How much does it cost to replace windows?

On average, the cost of installing new uPVC windows in a three bed UK home is £4000. It’s difficult to estimate how much replacement windows would cost for your home, without seeing it and understanding all the details. This figure is a good starting point for building your budget.

There are several factors to consider when thinking about replacing your windows. Firstly, count how many windows you have in your home – it sounds simple! This information will be essential for estimating prices.

Next, look at the type of material that your window frames are built using. For older homes, the frame is usually timber or wood, which can rot or grow mould over time. You may have uPVC frames that are warped, worn, or tired with age. Consider if you’re planning to replace your windows with the same frame material, or looking for an alternative material.

Thirdly, take a look at the windows themselves. Are they single pane, double glazing, sash or casement windows? This will have an impact on the type of windows you can install. Again, think about whether you will replace the windows with the same pane type, or move to a more modern design that saves on energy efficiency.

All of these factors will impact the cost to replace windows, and in this article, we’ll look at the benefits of each material and design. This will help you to choose the right type of window for your home and your budget.

Window Prices: Frame Materials

Let’s take a look at the pros and cons of each frame material and the impact on costs.

uPVC Window Prices

uPVC windows are the cheapest option and often the most common for homeowners in the UK. They are easy to maintain with soap and water and come in a range of finish colours, including white, grey and brown. However, the cheaper uPVC frames are not the strongest material and can warp over time, meaning that they’re not a great investment in the long run.

The prices for uPVC are variable depending on the quality, but typically a small 60cm by 90cm double glazed casement window would be £300. A larger 1200 x 1200mm can be around £700. Also, if you’re looking for a different colour finish or additional window locks, you can expect to pay a higher price per window.

Aluminium Window Prices

Aluminium frames are more expensive than uPVC but deliver the best on reliability as they are long-lasting and durable. They are also aesthetically pleasing with sleek lines and a range of finish colours. The slim frames are ideal for hard to fit areas, and the aluminium offers better energy efficiency than uPVC. Aluminium is also easy to maintain and won’t rot like timber frames.

Keep in mind that they are more expensive – nearly double the cost of uPVC frames. On average, a small 60cm by 90cm double glazed casement window would be £500. A larger 1200 x 1200mm can be around £1,000 with aluminium frames. If, however, this is in your budget, we highly recommend aluminium as the most durable and stylish frame.

Timber Window Prices

Timber is the traditional material for window panes, and often older homes with casement or sash windows will have wooden frames painted white. However, over time timber can rot with the exposure to sun and rain and requires maintaining or replacing. The choice to replace your classic timber frame old windows is a good one, as timber frames can add an elegant and stately feel to your home, especially if they are well maintained.

However, timber is often a higher cost than uPVC and aluminium and requires more maintenance, so carefully consider this before purchasing. For a small 60cm by 90cm double glazed casement window, the average cost would be £900. And for a larger 1200 x 1200mm window, the cost can be around £1400. Once you add this up to all the windows across your house, it can be a large investment.

Cost of Window Types

There are many different styles of windows in UK homes, and when looking at replacement windows, you may be limited to the period style of your home or area or the current shape and size of your old windows.

We’ve looked at each style of window, and the average replacement windows cost for the style, to help you consider which is right for your home. All price estimates are based on white uPVC windows, as this is the common choice for UK homeowners.

Casement Windows Prices

Casement windows are the most popular style of windows and have been around since the 17th century! Many modern homes use casement windows because they are versatile and can be fitted into the window space using a variety of shapes. For example, many UK homes will have a large pane with a small opening horizontal pane at the top. Or they might have three large windows with the centre pane stationary and the two side panes open vertically. This style of window is available in all frame materials and can offer good flexibility to your window design.

This flexibility and range, however, makes it difficult to estimate the costs of windows replacement for your home. Replacement windows cost can vary greatly depending on the style and size of each pane. Smaller panes with fewer openings are cheaper, and large panes with more openings and locks are more expensive. The range of replacement window cost, therefore, stretches from £500 to £1,500 per window.

Despite this, a casement window in uPVC setting remains the most affordable option for installing reliable and high-quality double glazing windows in your home.

Sash Window Prices

Sash windows come in two distinct styles: either a patchwork of small rectangular panels that are held together in a large timber frame or two large clear panes in a timber frame. A sash window works by the lower section being pushed up and overlapping the upper frame.

Sash windows also have a pulley system built into the frames to ensure the panes remain up when pushed. This style is traditional in Georgian and Victorian homes and is associated with class and style. They are however, not very energy efficient, sometimes lack in natural light, and can be drafty.

As they are built with a timer frame, they are typically more expensive than most other styles, and the windows cost between £500 and £900, depending on size. Many homeowners do not install sash windows unless to replace and restore the traditional style of the house.

Tilt & Turn Window Prices

Tilt and Turn windows are versatile in that they can be opened wide into the room or opened by a few inches at the top of the pane. The mechanism is built to add flexibility and airflow while keeping people safe. This option is common in homes with children and public buildings such as schools.

This style is surprisingly not as expensive as you may think and is similar to the cost of standard uPVC frame windows. A small 60cm by 90cm window would be £300. A larger 120cm by 120cm can be around £700. You may choose to just have one or two of these types of windows in your house, such as in a family room or nursery.

Bay and Bow Window Prices

Bay and bow windows are different, thanks to their build and structure. The windows curve out from the rest of the room, creating a sunny nook or reading corner. Most are built into the structure of the house, and so replace windows like these is a slightly difficult task. The cost of these windows is much the same as a standard casement style. They can be more tricky to get to, however, which means the windows’ cost may be more due to the installation and labour prices.

Prepare for replacement windows

To have a good estimate quote, make sure that you are clear on your choice of window frame material and window style. You will also need to measure the windows properly.

We recommend taking several window measurements, including the glass pane, frame, and the overall size of the gap your windows will sit in. By providing a good level of accuracy from the beginning, you’ll get a more accurate quote and will avoid costly problems down the line.

It’s important to also consider labour costs into your budget, which you can get a quote for through Quote Check. Remember that upstairs windows will need scaffolding to be safely installed.

Benefits of double glazing

Many modern homes will have double glazed windows – but what does this mean? Double glazing is where two panes of glass are built into the window with an air pocket between them. This style of window drastically improves installation, saves a large amount of heat getting out through the window, and reduces cold air coming in.

If you currently have single glazed windows that you’re replacing, we strongly advise upgrading to double glazing as it will be more cost-effective in the long run. This is the most popular choice for new windows in homes across the UK as it saves on heating bills and also reduces noise pollution.

When thinking about installing new windows, it’s important to consider the cost of the windows’ style you’d like in your house, while also considering the labour costs involved.
