How much does it cost to replace windows?

It can be difficult to estimate the cost of new windows without seeing and assessing your home, which a tradesman or window fitter will be able to do. On average, the cost for new windows in an average three-bed UK home is £4000, which you can use as a good base point for building up your budget.

There are several things to consider when estimating the cost of new windows in your home:

  • Number of windows in your home
  • Type of frame material
  • Pane thickness – single or double
  • Style of windows
  • Period or style of your home

Firstly look at the number of windows in your home. This sounds simple, but it will be essential for creating a quote for new windows. Try to be specific with measuring the window panes and frames, which will help to make your quote as accurate as possible.

Secondly, check out the type of material that your window frames are currently made from, and the condition of these frames. Many older homes would have been built with timber or wooden frames, which over time, can grow mould or rot, and expand in hotter months.

The frames may be uPVC, which can warp or wear over the years, with bacteria building up around the frame and lock. Think about which material you’re planning for your new windows. Will it be a like-for-like replacement, or will you choose a newer and stronger frame like white uPVC?

Next, assess the look of all the windows in your home – are they using single pane or double pane? Are they standard casement windows or a particular style, like sash or bay windows. Are you choosing to replace the windows like-for-like? Or move to a more modern material and thicker pane that will be more energy efficient.

If you’re completing a self-build, you may have more freedom to choose whichever new windows you’d like or a combination of styles.

Each of these factors has an impact on the cost of new windows in your home. Through this article, we’ll consider the pros of each window material. This should help you to choose the best new windows for your home.

Benefits of Double Glazing

Double glazed windows are the standard choice for modern UK homes and are the recommended option. This is because double glazed windows are best for temperature control in your home.

They keep warmth and heat inside your home and cold air out. Double glazing made from two panes secured with an air pocket between them, making these replacement windows strong and reliable.

The double glazing cost is pricer than single panes, but it’s definitely worth the investment. On average, people that switch from single to double glazed panes save £150 a year in their heating bills, which builds up to a considerable saving over time.

If you currently have single glazed windows, we strongly advise upgrading if you can. Have double glazed replacement windows. You’ll find that double glazing windows will help to make your home more comfortable with better heat retention and less noise pollution.

Window Prices: Frame Materials

We’ve assessed the pros and cons of each frame material, and the estimated cost for window replacement for UK Homes. This will help you to choose the right frame and understand the prices involved.

Timber Window Prices

Timber is the most traditional material for window frames and has been used in the UK for centuries. Timber was often used on new build homes up until the 70s and 80s when uPVC models became available. Timber frames are often found with casement or standard windows, but look particularly good with period Victorian or Georgian sash windows.

In these period examples, timber can add a stately and elegant feel to your home – just be sure to maintain them well. If not properly maintained, timber frames can rot from sun and rain exposure, which is why they have become less popular with homeowners for windows replacement in the last 20 to 30 years.

Timber frames are the most expensive frame material and require frequent maintenance, so think carefully before purchasing your frames and replacing old windows.

1200mm by 1200mm double glaze casement – estimate cost £1400

Also, remember that fitting specialist window styles will have a higher price. Once you calculate this for all the windows in your home, it can be a costly investment.

Aluminium Window Prices

Aluminium is a brilliant and stylish option for windows and is often used on warehouse conversions or new builds where the windows and walls have been completely remodelled. Aluminium gives a sleek finished look that is available in a range of colours.

The frames are slim and can be fitted in hard to reach areas or thinner walls. Surprisingly, aluminium frames offer better energy efficiency than uPVC, but they are more expensive.

The cost of aluminium frames is nearly double that of uPVC frames:

600mm by 900mm double glaze casement – £500 per window
1200mm by 1200mm double glaze casement – £1000 per window

When considering your budget for new windows, it may be that you choose to have one or two aluminium framed centrepiece fitted windows, and replace other windows with grey or black uPVC.

uPVC Window Prices

For many years, uPVC has led the way in fitting new and replacement windows and is the most common for homes across the UK. Not only are they the cheapest material to use, but they are also reliable and durable and easy to maintain with soap and water.

They can sometimes warp or expand in a very sunny area but usually hold their shape well. uPVC windows also come in a range of finishing colours – the most popular being white, but grey, black and brown are also available to give a different look to your home or to blend in with the area.

Beware of buying the cheapest uPVC window frame options, as these can often be made with less durable plastic. They will warp and bend over time, hampering your initial investment and causing extra cost down the line.

The cost of uPVC windows can vary depending on the quality you choose, but on average the prices are:

600mm by 900mm double glaze casement window – £300 estimate
1200mm by 1200mm double glaze casement window – £700 estimate.

If you’re looking for additional features – finishing colour, additional locks, small top windows – then expect to pay a higher price per window.

Cost of Window Types

When replacing your windows, you may be limited by the style of your home, or by the current shape of your windows. These factors may mean that you have to choose a particular style of window to suit your home’s appearance. Alternatively, if you’re replacing windows in a modern home or self build home, you may have more flexibility to choose new windows.

We’ve looked at the most popular types of windows in UK homes, the average cost of each style and other factors to consider when choosing these windows. We’ve based our estimates on the cost of double glazed uPVC windows, as these are the most common choice for homeowners.

Casement Windows Prices

Casement window styles are the most popular style across the UK because they are versatile, simple and can be customised into a rang of pane shapes. Many UK homes have a large windowpane with a small horizontal opening pane at the top, which is great for kitchens and hallways.

Casement window arrangements offer good flexibility in design, but this can make it difficult to estimate the cost of windows for your home. Smaller panes and fewer openings are cheaper, and larger panes are more expensive. Therefore the cost ranges from £500 to £1,500 per window.

Even so, casement uPVC windows remain the most affordable and popular option for replacing windows in homes across the UK.

Tilt & Turn Window Prices

Tilt and Turn windows are a clever piece of design work that enables the window to be opened in two ways – traditionally like a door, and also turned to open a few inches at the top of the window frame. This design is a great option for children’s rooms, as it’s flexibility helps to keep people safe. These windows make for a popular choice in schools, nursery, offices, and apartment buildings.

Tilt and Turn windows cost less than you may expect and are similar to the price of uPVC frame windows. Typically a 600mm by 900mm window would be £300 and a larger 1200mm by 1200mm window around £700. You may choose to have just one or two of these windows, perhaps in the children’s room or kitchen in your home.

Sash Window Prices

Sash windows are usually made from a timber frame and have two large horizontal sections. To open, the lower section is lifted and held up using an internal pully system. The sash window is popular in Georgian and Victorian houses and is a beautiful and stylish feature on these types of homes. However, in the modern day, they can be drafty, a security risk, and low on energy efficiency ratings. Some sash windows are made up of several small frames, which can reduce natural light coming in.

This style is more expensive than others, thanks to the timber frame and unique build. It costs between £500 and £900 depending on the size and complexity of the window. Many people do not install new sash windows unless to replace an existing traditional design.

Prepare for Replacement Windows

When choosing replacement windows, it’s important to have a clear image in your mind of which type of windows and which frame material you’d like to use. Also make sure you have accurately measured all of the windows and frames, and provide this information to your window installer.

Be sure to measure the glass pane, the frame thickness, and the overall size of the gap your windows will sit in. This will help to get an accurate quote and avoid mistakes down the line, which could cost you extra money.

Furthermore, make sure you add labour costs into your budget, including labour day rate and scaffolding for upper floor windows. There may be an extra cost if your windows are hard to access or on a terrace.
