Glass conservatory roof vs. tiled conservatory roof

Tiled conservatory roof

In recent years, tiled conservatory roof replacements have become more and popular. However, most homeowners with glass roofs chose to stick with what they know and invest in a new glass replacement conservatory roof!

Glass replacement conservatory roofs are popular for several different reasons! This type of replacement conservatory roof will let a lot of light into your home, making your conservatory enjoyable to relax in.

You’ll also get the feeling that you’re outside, without any of the hassles of cold temperatures and wind. Enjoy your garden from the comfort of your own home! Plus, if it’s raining, you won’t be disturbed by a loud sound as you would with a tiled conservatory roof.

A glass replacement conservatory roof will also keep you warm and cosy during the winter months as they offer great insulation compared to a tiled conservatory roof. Plus, in the summer, you’ll be able to keep cool and comfortable as glass also provides UV protection. You just don’t get that with a tiled conservatory roof!

A tiled conservatory roof is less durable than its glass counterpart. You’ll also love the low-maintenance and chicer look you’ll get with a glass conservatory!

New conservatory roof installer trade bodies and accreditation schemes
Now that you know a bit more about what you can expect to pay for new conservatory roofing, you may be wondering how to pick a good installer to get the job done. One way to know which installer to chose is to take a look at their accreditations and which trade bodies they belong to.

It’s a good sign if the installer belongs to one or more trade bodies and accreditation schemes. Trade bodies and accreditation schemes are there to make sure that you get quality work, and if an installer breaks certain rules, they are automatically kicked out.

If installers belong to these groups, it means that they’re required to abide by the rules the body and schemes abide by themselves. What does this get you? An installer that is dedicated to providing quality work!

Here are some trade bodies and accreditation schemes you should look out for:

  • FairTrades/TrustMark accreditation
  • Certification and Self-Assessment (CERTASS)
  • The Fenestration Self-Assessment Scheme (FENSA)
  • Glass & Glazing Federation (GGF)
  • Get the best installation for the best price
  • Before you decide on an installer, you’ll want to get several price
  • quotes! You also need to decide if you want to stick with a
  • smaller local company or go for a larger national one.

You will likely be able to find several options, both big and small, close to your home. You may recognise some of the bigger names from nation ad campaigns, but the same could go for smaller companies that advertise in your area.

As you begin to consider the options, you’ll find that there are pros and cons for both! A smaller company will likely offer lower prices, but you’ll want some assurance that they won’t run away with your money without completing the job. In this case, you’ll want to double-check that your local installer belongs to an accreditation scheme or a trade body.

You’ll also want to confirm that the company has builders’ insurance to protect themselves – and you – if anything goes wrong on the job. If you like the results, make sure to leave a review somewhere online to support them. Local companies can live or die based on customer reviews!

You may feel more comfortable going with a larger, more well-known company. These large companies are usually financially stable, so you know that your money is safe! Larger companies can also usually provide higher quality materials as they are required to use the industry standards.

They will usually work more quickly and efficiently than a local provider, simply because they likely have more business they need to get to! But, these upsides will come at a price. You can expect to pay up to 30% more than with a local company.

Ultimately, the choice is yours! Consider the pros and cons of each type of new replacement roofs and the different types of companies before you make a decision, and you’ll be glad that you did!

Cost of a Conservatory with Full Guide


A conservatory is an ideal way to increase the living space within your home. This type of home extension is favoured by many people and allows them to benefit from much needed extra space. A conservatory also lets a vast amount of light into the property. This is due to the glass panelling used in the construction.

Another benefit is that conservatory prices are a lot less than a full bricked home extension project. Conservatories are also much easier to construct, meaning they are built quicker than a bricked home improvement.

Conservatories are great for all year round use, and people use the space for their individual needs. Some people use them for additional storage space, while others see them as a tranquil area where they can relax and look through the conservatory glass windows to observe nature.

There is a mixture of materials used in the construction of a conservatory, which varies depending on the style of conservatory that is constructed. You can choose from a wide range of conservatory styles, ranging from Edwardian conservatory styles to contemporary conservatories that have a modern style.

The different types of conservatories will be different in cost. Victorian conservatory prices are generally lower than the cost of a contemporary conservatory because many of the modern conservatories are uniquely designed for an individual household. Even if you choose a contemporary conservatory that’s not unique in design, it will still be a higher cost than other styles.

Contributing Factors That Will Alter the Cost of A Conservatory

Many factors will determine the cost of your conservatory, and it’s worth considering these factors to ensure you purchase the right type of conservatory for your planned budget.

1. The Size of the Conservatory

Modern Sunroom Conservatory

As you can imagine, the bigger the conservatory, the higher the cost due to the use of more building materials. If it is a bigger size, it will take longer to construct by the conservatory fitter.

Conservatories range in size. Smaller types will create an extension of your property of around 8 feet or around 2.5 meters, which is useful if you intend to use the new space as an additional storage area or if you’d like to fit a few chairs in.

The standard size for a conservatory varies slightly, but it’s around 10 feet by 10 feet or roughly 3 meters by 3 meters. Depending on the shape of your conservatory, they may be slight variants of 10 feet by 8 or 12 feet or 3 meters by 2.5 meters or 3.5 meters.

This will provide adequate room for a family to sit inside. Due to it being much bigger, you will be able to fit much larger items in it, like a sofa or floor space for pot plants.

If you require a more considerable extension, the conservatory cost will increase significantly. But you will be able to make a larger conservatory much more of a living space. You will have room to place more seating, and you could even fit a table inside for those summer night meals. A larger conservatory size is around 10 feet by 20 feet or 3 meters by 6 meters.

2. Conservatory Style Will Affect the Overall Cost

Empty conservatory

As mentioned earlier, there is a wide range of conservatories to choose from, and some have a higher cost than others.

If you’re looking for the lowest cost for a new conservatory, your best choice would be the lean-to conservatory style. The conservatory costs for this style are low because the extension uses the wall of your home. This means only three new walls need to be installed.

The roof is also built out from the house wall. It then slopes down to join the rest of the frame. The Lean to conservatory is quite a basic design, but it’s a perfect choice if you’re looking to add an extension or if you’re considering selling your property. Homes with conservatories will always attract potential buyers.

If you’re looking for a new conservatory that’s a bit more styled or has a touch of elegance, then the Victorian or the Edwardian conservatory is a fantastic choice. The prices of conservatories styled like these are classed as a middle of the range in cost.

The Victorian conservatory is a classic style of conservatory that many people are aware of. It’s identifiable by its circular bay window type of design that allows you to see out onto the garden from different angles.

Just like the lean-to conservatory, this is a popular choice of conservatory. It’s been around for many years. The conservatory roof slopes down from a central point in the roof. Conservatories like this let in a considerable amount of light.

The conservatory cost of the Edwardian conservatory is worth it if you’re looking for an extension that has a more spacious design. This conservatory is rectangular and makes the floor size seem much bigger than other conservatories.

The conservatory roof also slopes down from a middle point of the conservatory but only has three sections as the front of the conservatory is flat, unlike the Victorian roof design.

If you like the idea of all the above conservatories or certain aspects from each one, then the P-shape conservatory might be an ideal choice for you. However, the conservatory cost for this extension will be a bit higher than the mid-range price.

The conservatory pricing will also fluctuate for this style, depending on the size that you choose. A P-shape conservatory combines both Edwardian and Victorian conservatory design. The lean-to conservatory element means that this conservatory can use the wall of the house.

The price of an orangery conservatory is at the upper end of the cost scale. It’s like getting a mini home extension. The conservatory roof style lets light in, and this style also brings other qualities that conservatories bring.

These types of conservatories can be uniquely made and designed for each house to ensure it makes the best use of space and fits in with the property feel. Planning permission is not generally needed for conservatories, but the orangery conservatory comprises of a higher level of brickwork.

This means you may need to check to ensure that planning permission isn’t required before choosing a conservatory like this. Ensure it complies with building regulations, too.

Contemporary conservatories are also at the top end of the price scale. They cost far more than other conservatories. These conservatories can benefit from features such as bi-folding doors, giving easy access to the garden. Some are made with floor to ceiling glass panels to create the ultimate modern look.

3. The Material Used for the Conservatory Frame

New conservatory

Conservatory prices will change based on the material that’s used for the frame of the conservatory. If you want to keep the cost low, you should opt for a uPVC conservatory frame. This type of frame will provide a strong structure and is made from plastic.

The plastic is generally white and will give your new conservatory a fresh look. uPVC conservatories are still the most common type of framework that people select for their conservatory.

The mid-range framework of a conservatory is the aluminium frame – mostly referred to as the metal frame. You will also be able to choose from different colour aluminium frames, so if you’re considering a contemporary conservatory, an aluminium frame would be the perfect pairing to enhance the modern look and ensure it’s to your liking. This metal is very robust and will last for a long time and won’t get affected by the elements.

If you have the capacity for your conservatory cost to increase, then a timer or wooden structure is a possibility. Unlike the uPVC conservatory frame and aluminium frame, this will require regular maintenance to ensure it’s durability. The high cost for this type of frame is mainly because timber needs to be treated before being installed. Plus, timber carries a heavy price singularly also.

4. Base Work Requirement

Patio roof construction

This factor will change all conservatories prices due to the different materials used and if more building work is required.

Base work is essential as the conservatory needs a good foundation to sit on. There are various types of base work, including concrete, steel, raised, and wooden.

Conservatory costs will be more if you choose a wooden, steel, or raised foundation. A raised foundation will be needed if the conservatory area isn’t level, meaning you won’t have a choice about that, unfortunately. It will be mainly made out of a timber structure.

Steel foundation conservatory prices are more costly than regular concrete bases, but one of the positives is it can be installed much quicker.

Concrete is the standard base that’s used for most conservatories. A new conservatory built with a concrete foundation will be the lowest cost-wise, although this depends if a dwarf wall is also going to be built. A concrete foundation will be laid on top of the ground to form a good solid floor base, or the ground will be dug into to create a solid foundation that will support a dwarf wall build.

5. Conservatory Wall Installation

Builder layering bricks wall

The conservatory cost can increase depending on what type of wall you require. The wall type options are either a dwarf wall – which is bricked a meter high from ground level to form robust support for the actual conservatory frames. Or you can go with a glazed wall, which is the actual glazing starting at the base and going right up to the roof.

If you’re going for one of the traditional styles of conservatory, like the Victorian, Edwardian, or lean-to conservatory, then a dwarf wall is generally the standard feature to go with. All of these styles can be fully glazed instead, but it’s not so common and might be more of a contemporary style instead.

Conservatory prices will increase if you opt for a dwarf wall. But in the long run, you can rest assured that you have solid support for the frame of your conservatory, especially if you select a tiled roof or thick glazed glass for your windows of the conservatory.

A dwarf wall won’t generally require planning permission as long as it meets the various requirements. If your dwarf wall falls outside of the permitted conditions, then you’ll need to apply for the planning permission and ensure your wall complies with building regulations.

The conservatory cost will be lower if you choose a fully glazed wall instead, which will mean your conservatory has floor to roof glass windows. You’ll get a lower cost mainly if you choose a Victorian, Edwardian, or any of the others (apart from a contemporary conservatory style.)

This type of fully glazed glass wall is common with the modern style, but these conservatories will cost much more due to them being specifically designed. Even if they’re not tailor-made, they’re of a more modern and fashionable style that does cost more.

One of the main aspects to consider when choosing your wall type is privacy. Whether you choose floor to roof glass windows is entirely up to you. Depending on where you live, and if you have neighbours close by, it could make you feel a bit exposed.

You’ll be able to put blinds up, but one of the main reasons people have conservatories is to benefit from the light and openness that comes through the glass windows, so this is something to consider along with security.

You should also think about insulation when deciding on the perfect wall. A dwarf wall will give you more insulation due to its brickwork design, the same way that your walls within your home are insulated. They will provide you with warmth, and they contain airbricks to allow the circulation of air.

Fully glazed glass floor to roof panels won’t be as insulated, although there are many different types of glass that you can choose from. So if you like this conservatory look, select a glass that will help to insulate.

6. The Type of Glass Used

Glass conservatory

There are many different glass options to choose from for your conservatory glazing. Conservatory prices will increase if you opt for a glass that has more features on it than others.

Seven glass options are available, from standard glass to extremely strong glass for added security.

Standard glazing is classed as normal double glazed or triple glazed glass. You’ll find it used in conservatories from steel-framed to framed uPVC conservatories. It’s the most popular choice. It’s very tough and will meet the needs of all households, so the good news is you can keep your costs down slightly by choosing this standard glass option.

If you’re looking for glass that’s a little bit special and will make your life slightly easier, then you can choose a self-cleaning glass. It can sound strange when you first hear this term as you don’t usually come across self-cleaning windows, but these can be an ideal addition to your conservatory.

If your glass is large, this could make your cleaning chores less, although the only difference that you might notice from a standard glass is the amount of light that comes in through the glass. This is only a slight difference, and many people don’t even realise.

A concern that many people have regarding conservatories is if it will be too cold or too warm at different times of the year. If this concerns you, then a low E glass might be the best pick for you. The conservatory cost will increase from a standard glazing price but may be worth it, especially if you live in an area that’s prone to the extremes of weather elements.

This type of glazing contains a metallic coating that will prevent warm air from escaping and entering. This ensures you can utilise your conservatory’s living space all year round.

Another couple of glass types include glass that will reduce the level of noise that enters your windows. This is ideal for urban areas. Alternatively, you can choose to have stained glass that is decorated with colours, or a unique decretive pattern. It makes for a subtle look if you add a few decorative panes of glass to add more character to your new conservatory.

It doesn’t necessarily need to be everywhere. You could choose to decorate a small window. The noise-reducing glass is perfect if you want to create a quieter ambiance while you look out at your garden.

If you want a glass that is four times stronger than the standard glass, then toughened glass is perfect for your conservatory. Conservatory prices will increase with this, but it will ensure the glass is safer if it breaks.

This is because glass that’s toughened will break into small pieces rather than large sharp segments. Depending on the size of the glass you’re using in your conservatory, this may be a safer option. This is especially if you have floor to roof glazing.

The most costly glass is the laminated glass. It’s similar to the toughened glass as it has the same strength, but it also includes a plastic layer that stops the glass from falling if it breaks. The glass will remain in place, which makes it the safest type of glass. It will increase your overall conservatory cost, but if you have the fully glazed floor to roof style, this option is worth consideration.

7. The Conservatory Roof

Conservatory roof

There are many roof styles available for you to choose from, including a tiled roof or a polycarbonate roof. It’s entirely up to you the type of roof that you select for your conservatory extension. You may favour a roof style that lets in optimal light.

This allows you to feel like you are outside but with the protection of the conservatory. You may prefer a roof made using tiles to fit in with the look of your house. This will make it feel like more part of your actual home as light won’t come in from the top.

The conservatory roof is an important feature that you need to think about, and also it will affect the final conservatory cost as a polycarbonate roof will be cheaper than a tiled roof.

If you want a roof that allows as much light into your conservatory as possible, then go for either a glazed roof or polycarbonate.

There can be some negatives with a glazed roof. Your conservatory could become too warm in the summer, and you may be septuple to more noise entering your conservatory. If you want to benefit from more light, then you may be able to oversee these negatives. Plus, there are various types of glazing that you can select that will reduce these factors.

The polycarbonate roof will decrease the overall conservatory costs. It’s a lot quicker to fit than glass, and it’s lighter in weight. This type of roof won’t require you to have a dwarf wall, as it’s the lightest option available.

The negatives are the same as the glazed roof, but if these don’t concern you and you want to make a small saving, then this might be the best way to reduce the overall conservatory cost.

Another conservatory roof option could be a tiled roof. There are two types to choose from. You can go for the traditional kind of tiling, which is completed in the same way as the roof on your house. Your installer will lay tile by tile to achieve this look. Or you could choose a tiled roof that’s pre-made in the factory; it’s simply placed on top of your conservatory frame and fixed.

There are many positives to having a traditional tiled roof, but it will increase conservatory prices. If this is your chosen option, then other, more costly features will need to be selected, including a dwarf wall and possibly a reinforced frame to be able to support the weight of it. A trained roofer may be needed to complete this job, and that can also add additional costs and be more time-consuming.

A pre-made tiled roof won’t always necessarily be as heavy as a traditional roof so that it won’t require strong supporting walls. The positives of having a pre-made roof are that you can have all the features of a tiled roof but in a lot less time. It’s simply placed on top of the conservatory frame and fixed.

The positives for a tiled traditional roof are that you can fully insulate your conservatory to ensure it’s usable all the time and can reduce outside noise. If you’d like to have more light into your conservatory, then go for built-in skylights.

This will let more light in, but you will still benefit from the tiling feature. Although this choice will increase the conservatory cost, it does give you the best of both worlds.

8. Internal Conservatory Features


You may wish to have a few built-in features inside your conservatory to make it more homely.

You may consider having a shelf unit built-in around the perimeter of the conservatory. This will provide you with the space to place objects on like photos or ornaments. If you have chosen a small-sized conservatory, then it may be best not going for this option and, instead, just sticking to plastering the dwarf wall – if you have one.

You can finish it in your chosen style. Conservatory costs will increase slightly if you want to have extra features inside, but some may be worth it to give you the living space that you desire.

Flooring is another cost altering feature. You can choose from carpet, wooden or laminate flooring, linoleum, and tiled. If you go for tiled, you may want to consider underfloor heating.

Your conservatory cost will depend on the type of features you choose to have. Always remember, though, some more fancy features may pay off in the long run, so try to think about what you want to use your conservatory for.

A legal aspect to think about when designing your conservatory build is planning permission. Conservatories don’t usually need planning permission due to the size of them, but there are a few exceptions to this when the conservatory that you want will fall outside of these permitted rules. Ensure you check if your conservatory falls within this allowed rights. If not, you will need to apply for planning permission.

If you’re having a brick wall built from floor to roof in height, then make sure you keep to all building regulations.

Conservatories can be achievable for people who only want to spend a little bit of money on extending their homes and for people who are quite happy to pay a large amount of money to get a tailor-made conservatory. Prices will range, and they can be between £5,500 for a lower budget and up to and exceeding £20,500.

Lean-to Conservatory Cost (2020)


What Does it Cost to Build a Lean-to Conservatory?

Modern house conservatory

Have you always dreamt of having a conservatory built onto your home, but is the cost holding you back? Well, have you considered a lean-to conservatory? This type of conservatory is perfect if you’re on a budget but still want to gain extra space and extend your home.

A lean to conservatory can be used to increase the space of your home, create additional storage space for large items, and to give you a place to relax while looking at your garden.

The reason you might want a lean to conservatory may be different from the above. But the great thing about lean to conservatories is that you can use them for anything that you like and will cost less than having a new extension built onto your home.

One of the best features of a lean to conservatory is that it allows maximum natural light into your conservatory compared to some of the other styles of conservatories that have a different type of roof. The lean-to conservatories have a sloping roof, which is usually made from either glass or polycarbonate, and these materials allow light in from every angle, including the sides.

Lean to conservatory prices will alter depending on the type of specification you select. You can choose from many different materials and even include dwarf walls, which will add to the overall conservatory cost. Although a lean-to conservatory cost is lower than other conservatories, such as the Victorian, Edwardian, and Contemporary, these new conservatories cost are a lot more – especially Contemporary conservatories.

Conservatory prices can vary widely. For all types of conservatories, the cost ranges between around £5,000 and up to and exceeding £20,500. The lean-to conservatory cost dips towards the lower end of the price range. You can pay between £5,000 and £10,000, based on the materials you choose for your new conservatory.

Lean-to Conservatory Features

Lean-to conservatories have design features that identify them from other conservatories, such as a sloping roof that starts on the wall of your home and slopes down meeting the side walls. This also helps with drainage for the conservatory roof.

A lean to conservatory is rectangular and can also be square, depending on the size of conservatory you require.

The structure of lean to conservatories is always with straight lines. There are no curved features that can be found on conservatories like the Victorian.

Due to lean-to conservatories being relatively small in design, and their simple structures, you don’t generally need planning permission to construct one. However, you should always check to make sure.

Factors That Will Affect the Price of a Lean-to Conservatory

A wide range of factors will have an impact on the overall cost of your new lean to conservatory. You should be aware that specific features, such as a dwarf wall, can add a significant price increase, and you could save money by omitting this and opting for a fully glazed wall instead.

The Type of Wall You Select for Your Lean-to Conservatory

Glass wall conservatory

Lean conservatories can be constructed with two different types of walls. You can choose between a dwarf wall or a full height glass wall. Depending on which one you want, lean to conservatory prices will increase. That’s if you select the dwarf wall to be built instead of the full height glass wall.

If you want to keep your lean to conservatory prices at the lower end, then it’s advisable to go for the full height glass walls. This means that your lean to conservatory will have double glazed panes of glass. The glass will go from the floor to the roof of the conservatory. There are other glazing options if you prefer, but these will also affect costs.

This fully glazed look can work well with a home that requires a lot of natural light. It will make your space seem bigger than it is, which is a bonus. Another plus to having a glazed wall is that you can achieve a slightly modern or contemporary look of a conservatory but on a budget.

Many of the modern conservatories have this feature of floor to ceiling glass within their design. Unlike lean-to conservatories, the contemporary conservatories are at the higher end of the scale – they cost up to and beyond twice the price of a lean-to conservatory, creating a luxury look but with less cost.

The other option is to have a dwarf wall built for your lean-to conservatory. Dwarf walls will cost more as brickwork can be costly and will also require more materials to be used, such as the bricks themselves, and the concrete.

The ground will need to be excavated. Not only are more materials needed to construct dwarf walls, but you also need to consider the labour costs, too. It will take longer to build as the ground will need to be prepared thoroughly.

The initial digging process could take a while, depending on if they encounter any unforeseen issues while the ground is dug-out. The dwarf wall will also need time to dry and set before any framework can be placed on top to ensure it creates a sturdy and robust base structure. Otherwise, in time, issues will start to appear on the conservatory.

There are a few aspects you should consider before deciding which wall you would like to have on your lean to conservatory. If your garden is over-looked by many other houses in your area, then a full glass pane may not be the best answer. Although cheaper, it won’t provide you with any privacy as the whole space is visible.

You can purchase blinds that you can fit internally and close them for privacy. But you won’t want these closed during the daytime, and they will prevent natural light from entering your conservatory. The reason for many people to have a conservatory is not just for added space, but to allow them to look out onto their gardens.

Another aspect to consider is whether you’re going to have a heavy framework installed. Even though it will cost more, a dwarf wall is recommended as it can effectively support a heavier framework, such as timber. It will also offer more privacy than a glazed wall as it will be around a meter high and will prevent your new home space from being completely visible.

The only area that will have more glazing is where the French doors will be placed, so you can strategically place these to the side of your conservatory instead of the front to prevent opposite neighbours from seeing directly through.

If you do have a dwarf wall built, you might need planning permission, depending on where you’re building conservatory. Although, it should fall within the permitted regulations but double-check.

The Type of Framework Used for Your Lean-to Conservatory

Conservatory prices will be largely affected based on the type of framework you choose. There is a choice of three materials for your framework, which includes uPVC, aluminium, and timber.

Each of these materials will have an impact on the overall look of your lean to conservatory. Plus, if you live in a particular area, such as a conservation area, or a listed building, you may need to keep in with the natural feel.

This may be non-negotiable, and you might need to have a timber frame built on to your conservatory. It’s best to check if planning permission is required for your property if you do fall in the above categories.

The most favoured choice for many people is the uPVC framework. It’s a durable material, and it’s easy to maintain. If it becomes dirty on the outside, you can simply wipe it clean. Also, uPVC is featured on the framework of many windows and doors of each home within the country. You won’t need to worry if this style will blend in with the rest of your home.

Another positive regarding uPVC framework is that now there’s a vast range of different coloured uPVC that can be used, so you don’t have to stick with a white frame if you prefer something a little bit different. Also, by choosing a coloured frame, you can again make your budget conservatory look slightly like a contemporary one as these modern custom-made conservatories generally avoid white framework.

If you opt for a coloured uPVC framework, it may cost slightly more than the original white uPVC colour. But if you don’t mind the original look, then you could save money on this feature and ideally spend it on another conservatory feature.

The most expensive framework is one made from timber. But, as mentioned before, you might not be able to get around this and need to install this more expensive frame. However, a timber frame can give your lean to conservatory a more eloquent look if you’re happy to pay a bit more for this specific design feature.

In terms of maintenance, a timber frame will be more time consuming than both of the other materials. This is because the timber needs additional care and treatment to ensure it will last a long time. It needs to be kept in reasonable condition to support the conservatory windows and roof.

If you prefer something in the middle, the aluminium framework is an ideal option for your lean to conservatory. It will last a long time, and it’s easy to maintain in the same way as the uPVC framework. Just like the uPVC framework, there is a choice of colours, which gives you your desired look. It’s very similar to uPVC in the sense that it can provide your lean to conservatory with a modern and contemporary look without the price tag.

The Type of Glazing You Select for Your Lean-to Conservatory

Conservatory Open Windows

There are several types of glass that you can install for lean to conservatories. They range in price, and you could save a considerable amount of money by choosing to have standard glass in favour of laminated glass, which is the most expensive.

Also, bear in mind that most of your conservatory sides will be glazed. This is where a large increase can be seen in the overall cost if you choose to go for high specifications on the glazing

The following options are available for the glazing of your conservatory:

  • Standard glass – double glazed
  • Low E glass
  • Self-cleaning glass
  • Decorative glass
  • Noise-reducing glass
  • Toughened glass
  • Laminated glass

Each glass type has unique features and can be beneficial for homeowners in various ways. If you live in a noisy street, you may opt to have noise-reducing glass to ensure your new space is a peaceful environment for you to relax.

If you are going for a fully glazed wall, having noise-reducing glass may be the best way to make sure that you’re not disturbed by your outside environment.

The standard glass option is double glazed, although you can select triple glazed with a slightly increased cost. Most people choose this option, and it works well with any frame type. Another factor to consider is the type of roof you’re going to install.

If you’re going for a glazed option, you will most likely choose the same glazing for the roof. So to keep costs down, double glazing would be a good option. Otherwise, you will need to install higher-priced glazing to complete the roof.

For energy efficiency, Low E glass is the best option but more costly. It will keep your lean to conservatory at an optimal temperature throughout the year. The metallic coating on the glass prevents the transfer of heat from the outside. It does the same from the inside.

Self-cleaning is a good option, especially if you’re glazing your roof and going for floor to roof glazing. It works all year round and uses water from the environment to self-clean.

It will also help to reduce noise. If you don’t need the self-cleaning element, you could choose the noise-reducing glass instead. This is specifically designed to allow less sound into your lean-to conservatory.

If you like seeing colour in your windows, you can select a decretive glass instead. You may not want to put this all around the conservatory, but you could choose specific areas to inject a bit of colour and prevent your conservatory from looking dull.

Toughened glass and laminated glass are very similar, apart from the price and one feature. Laminated is more expensive and contains a plastic film that protects you if the glass was to break. If the glass breaks, the film stops it from falling.

This is a great safety feature and you should consider it to prevent accidents, especially if you have a full-glazed wall. Plus, it’s an additional safety feature. Both toughened glass and laminated are up to four times the strength of standard glass, so it might be justifiable to choose and pay more to install this glass into your lean to conservatory.

The Type of Roof Installed onto Your Lean-to Conservatory

The lean to conservatory roof is normally made with polycarbonate or is glazed. You can get the roof tiled if you prefer this look, but it will cost more and will take longer to complete.

Polycarbonate, used to be the standard for a lean-to conservatory roof as it’s low in price, can be installed quickly and allows rain to drain off effectively. During heavy rainfall, a polycarbonate roof can be noisy as the rain lands on it, but if that doesn’t bother you, then this type of roof could save you a lot of money.

If you want to glaze your roof, you can choose from a wide range of glass types at various costs, as mentioned above. A standard glass works well for the roof. You could lower costs by selecting this type, but it’s a good idea to remain consistent with the glazing that you choose from the side, especially for the noise-reducing glass, self-cleaning, and the Low E glass.

The Size of Your Lean-to Conservatory

Spacious conservatory

This will be a significant factor in your lean to conservatory price.

If you don’t require a lot of space in your new conservatory, then you could choose a small size and keep costs down. If you do need as much space as possible, you can opt for a larger size but then decrease some of the other features. Choose a standard glazing option, with a polycarbonate roof if you are tight on your budget. This will then allow you to increase the floor space of your conservatory.

This is an excellent strategy to apply to other features. For example, if you want a dwarf wall built for privacy and don’t mind the size of your conservatory as long as you have an outdoor space, you could opt for a small lean to conservatory.

One of the great features of a lean-to conservatory is that you can build it onto any sized home. If your house is only small, you can make a small conservatory, and it will keep in with the style of your house and not take away too much garden space.

The Internal Design Features of Your Lean-to Conservatory

The inside of your conservatory will need to be designed to your liking. The cost will be dependant on certain features you choose.

You will need to decide on the type of flooring that you would like. Carpet, vinyl, and laminate flooring are cheaper options, whereas tiled and real wood flooring is more expensive.

The type of blinds you have on the inside is a factor to think about, or you could do without and make a saving.

Does a Lean-to Conservatory Need Planning Permission?

The good news is that most lean to conservatories don’t need planning permission. However, you should make enquires to ensure that your lean to conservatory is compliant with regulations. If it doesn’t comply with the rules, you will need to apply for planning permission. That can sometimes cost you a fee.

How Much Will an Orangery Cost in 2020


Orangeries may not sound like a common part of the house these days, but they were once one of the most exclusive and luxurious of household areas. While less common, there’s no denying that there’s a ton of benefits to be enjoyed from getting one.

From being a highlight and talking point to adding value to your property, and then all the days of use you’ll get from it, it’s well worth considering an orangery if you’re trying to breathe new life into your house.

But where do you get started with an orangery, and most importantly, how much is it going to cost? In today’s guide, we’re going to detail everything you need to know about the cost of your orangery.

The Basics: What is an Orangery?

House with orangery

Let’s start with the basics. An orangery is a room that is very much like a conservatory, except it comes with a brick base and sides, plus a flat perimeter roof lantern. Most commonly, orangeries are referred to as ‘home extensions,’ especially since they can be used for any kind of home use.

If you’re looking to expand and add space to your home in a luxury way and want a variety of styles that you simply can’t get with other designs like conservatories, this is the option for you.

The Pros of an Orangery

Easily the biggest pro of building one is the fact that it’s a much more connected design to your house than a traditional conservatory. Even if you’re using the orangery as an inconspicuous extension for a new kitchen, dining room, or even a new living space that doesn’t look as separate as a conservatory, this is the extension for you.

Hand in hand with the pro above, orangeries are usually designed in a way that matches your existing buildings and materials. This way, it won’t make much of a difference and doesn’t stand out too much. Orangeries are also renowned for letting in impressive levels of natural light.

Thanks to the brick foundations and sides of orangeries, these allow the extensions to carry much more weight, allowing for the use of brick and stone roof lantern that you simply can’t achieve with conservatories.

From a sustainability standpoint, these kinds of walls and roofs are also ideal for optimising heat insulation, which can help to reduce your heating bills. All of these come together to make orangeries very attractive prospects.

The Cons of Orangeries

The only real con of investing in an orangery is that it can be more expensive. It will require a lot more orangery design work and input to ensure the extension fits into your existing building properly.

Also, while orangeries do let in a lot of light, they let less light in than conservatories. But this, of course, varies depending on the windows you put in or openings.

The only other potential con of an orangery is the disruption it’s going to bring to whatever area of the house you’re connecting it too. However, this would happen with any kind of extension.

How Much Does an Orangery Cost?

House with conservatory

So, onto the main question. How much does an orangery, or the cost of an orangery building process, going to be? Well, as a general average, the orangery prices average is around the £15,000 mark.

Don’t cringe too much at those orangery costs because, although the highest orangery cost you can expect to pay is around £20,000, you can find basic orangeries cost around £10,000.

Sure, this average orangery cost more than your typical traditional conservatory. Still, with orangeries providing much more space, much more functionality, and a much more stylish and luxurious experience, it’s well worth every penny.

When you break this time, this means that you should budget between £2,000 and £2,500 per square metre. If you were opting for the largest kind of orangery, around 4.5m x 3.5m, this is going to be around £35,000, but the sizes you opt for will completely depend on you.

Also, check the cost of orangery and orangery prices with your contractor to get a quote that suits you and your budget.

It’s worth remembering the ‘Golden Ratio’ when it comes to sizes. If you have an average house width of around 28-feet, the ratio for your orangery is around 17.5ft. This ratio will give your orangery extension the right look for your specific house.

Finally, you’ll also need to consider how much the materials are going to cost, as this will affect the price variably.

If you’re going for a basic white UPVC or timber frame, your orangeries costs will be around £15,000, but large, multi-material builds will be the most expensive.

How Long Does Building Take?

Typically, an average orangery will around three to five weeks to build, but this is dependant on a range of factors. These factors include things like the size of the build, its complexity, and how many custom elements you’ve ordered.

You may also need some other works to be done, such as electrical or plumbing work, or laying new foundations, but your contractor will be able to advise with this.

Do You Need Planning Permission?

As the UK law states, you must acquire planning permission from your local council if you want to build, change, or use any kind of land or building in a way that differs from the original structure. You’ll also need to check your local building regulations to ensure you meet them.

With that in mind, yes, in most cases, you’re going to need planning permission for your orangery. However, some exclusions allow you to use build one.

These exclusions include;

The orangery extension must be single-story and must have the following criteria.

  • The property is already extended in some way.
  • The materials on the extension are similar to the materials already used on your home.
  • The roof of the orangery doesn’t extend over more than half of your garden.
  • The extension roof does not extend higher than the top of your home or property.
  • The overall height of the orangery isn’t higher than four metres.
  • You don’t currently have balconies, raised platforms, or a veranda.

If you fit these criteria, you may be able to build without planning permission, but you’ll need to contact your local council to make sure you’re not breaking the law.

Do Different Materials Change the Price?

The materials are a very important aspect you’ll want to think about when building an orangery, and will very much determine the overall cost of your build.

The standard materials, like glass for the windows, will cost the same throughout the country, but the biggest difference will come when choosing the framing for your orangery.

There are plenty of materials to choose from. This includes uPVC, aluminium, a timber frame build, or a composite of all.

While each material has pros and cons as to why you would choose it, in terms of cost, the uPVC orangeries are the most affordable.

This is thanks to the plastic build, wide availability of the material, and the fact its relatively maintenance-free. On the other hand, the average cost of a timber frame would be the most expensive but is also known for being the most beautiful.

The same applies to the roof of your orangery. There are plenty of different styles available. Some include simple tiled roofs, which will be less expensive than their complex frame and glass counterparts.

If you really want the best experience and you want to go all out with your orangery, you can even invest in a self-cleaning roof. This roof uses the latest technology to keep itself clean during the times of the day when you’re not using the orangery – usually the night time.

What Kind of Size is Best?

One of the first steps you’ll take when choosing your orangery is finding the design and size to suit you. Of course, you can use the Golden Ratio we spoke of above to find the perfect size for your specific property.

Just to recap, the Golden Ratio would take the width of your house, let’s say the UK’s 28ft average, and then use the 1:1.168 ratio. This means your orangery will 17.5ft long.

This is believed to give you the most aesthetically pleasing size of orangery for your property, but you can choose whatever you like, of course.

Aren’t Orangeries Just a Different Conservatory?

Open conservatory

While an orangery and a conservatory are very similar in lots of ways, the main differences to think about are the bases and the roof.

Unlike a conservatory, orangeries have brick bases and will have a centralised roof lantern. A conservatory typically has pitched lanterns. The base will be framed construction sides with no perimeter.

A conservatory is also usually defined as a building with over 50% of the wall area glazed with glass. Over 75% of the roof is glazed. Orangeries tend to have an under 75% of glazed roof.

So, Which Are Cheaper?

If we look at the average prices of building types in the UK, the average cost of an orangery will be around £18,000 to build. This includes everything from materials to labour costs.

Since materials and design complexity can add to the price, you’re probably looking at a price range of £15,000 to £35,000 for a 4,000 x 5,000 build.

On the other hand, conservatories that are custom designed tend to cost around £50,000. On average, orangeries are more affordable.

As we’ve spoken about above, it depends on your custom build. If you opt for a fully bespoke timber frame orangery with glass, composite materials, and a self-cleaning roof, you’ll be looking to pay more than that.

How to Design the Best Orangery for You?

Finally, with everything we now know, you’ll be wondering how do you design the best orangery for you and can help you save money throughout the build.

There are some simple questions to ask yourself.

  • What will I be using my orangery for in my day-to-day life?
  • What maximum size boundaries will I have to work with?
  • What kind of design/materials do I like and want to use?
  • Which part of my house will my orangery living space be connected to?
  • How will I make my orangery suit and aesthetically match with my existing property?

If you write down the answers to these questions, you’ll be able to design your perfect orangery for a price that suits you.

Remember, bigger is not always better. You’ll have a much more satisfying experience if you design your orangery to suit your needs perfectly. You’ll be much more capable of creating one to a budget that’s good for you.
