Conservatory Job Costs

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

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

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

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

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

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.
