For this reason, we don't show an average price list online because all our windows are bespoke made to precision fit your specific requirements.

How much do new windows cost? (2023) (3)

Casement windows

A casement window is the standard and the oldest style of window in the UK. Hinged at the side (or the top) for opening, usually with a single or pair of opening windows in one frame. Casement windows in white uPVC are the most economical style of window you can buy.

The average price for a casement window can be anything from £600 up to £1,800.

Sash windows

Usually found on period properties and buildings in London, the sash window is prized for its classic aesthetic appeal but its high maintenance compared to other windows. The window has two panels that slide up and down over the top of each other.

The cost to replace sash windows is usually 50% higher than an average casement window.

Tilt and turn windows

The tilt and turn window has become a hugely popular style for uPVC and aluminium windows because they can be securely left open for ventilation by tilting them inwards whilst remaining fully locked.

The cost of double glazed tilt and turn windows is 25% more than a casement window.

Bay windows

Bay windows are built out from the walls of the house and can require planning permission to build to the front of the house. The bay window has windows on the front and at the sides and for these reasons, bay windows are the most expensive to replace.

A uPVC bay window will cost 100% more than the average casement window.

The average price of uPVC windows

Unplasticised Poly Vinyl Chloride, otherwise known as uPVC, has been one of the most popular choices for double glazed windows in the UK since the eighties.

uPVC double glazing is thermally efficient, low maintenance and secure. It's also the most economical material for windows.

The average price for new windows with a uPVC frame is between £600 to 1,800 depending on size, glazing design and how many are being replaced in the property.

What to consider when comparing the cost of new windows online

If you want to compare the cost of new windows like-for-like, you need a full quote that factors in all requirements to see who really offers the best value.

To work out how much new windows cost you need to consider several variables:

  • Style of the frame
  • Size of the frame
  • Material used for the frame
  • Double or triple glazed?
  • Number of windows
  • Will you need scaffolding?
  • Do you need planning permission?
  • The cost of installation

The cost of a new window listed on a website might seem cheap at first, but installation costs can leap up if you need to erect scaffolding to reach high windows.

And, poor quality uPVC can warp - so it's a false economy and not a long-term investment when you have to factor in the early replacement of your windows.

How do other companies show the average price for new windows on their website?

You can buy windows off-the-shelf that are made to specific sizes in limited colours and materials. But, these windows are a standard size and don't take into account all the problems that can arise when fitting new windows:

  • Many houses have windows that are not a standard size
  • Frames are not straight due to building shifts
  • You might want windows to open a certain way
  • Or, want handles that are easier to reach
  • Listed properties have limitations on style or colour

Cheaper off-the-shelf windows are often not a perfect fit and to make up for this an installer will use excessive expanding foam around the edges to fill in the gaps.

This can also cause damp, draughts and shorten the life of your windows.

Be cautious of new windows prices before an installer surveys your property. Just like a builder needs to see your property before he can give you a price, a reputable window installer will need to see your home before they can give an accurate cost of windows.

How colour and finish can increase the cost of new windows

Frame colourAverage price for new windows (per casement window)
White uPVC£600-1,800
Grey uPVC10% more than white
Wood grain uPVC10-15% more than white

Beware of cheap double glazing

If something looks too good to be true, then it usually is. And when it comes to home improvements, never take the cheapest option as it will end up more expensive in the long-term.

More importantly, it can devalue your property for resale. A cheap new window is not going to offer guarantees of longevity or quality of materials.

Poor quality windows leave you at risk from:

  • Scratches on new frames and glass
  • Cheap uPVC can warp over time
  • Incorrect frame sizes that need excessive expanding foam to force fit
  • Bad installation that causes damp, leaks or draughts
  • Double glazing desiccant - where the double glazing seal fails and bits get in-between the glass
  • Condensation between the glass from poor seals
  • Fading on the frames


  • +

    How much are new windows for a 3-bed house?

    When budgeting the double glazing cost for a 3-bed house you will need a price for how many windows there are.

    An average 3-bed semi-detached house has 3-4 windows at the front and back = 8 windows.

    An average small detached house has 4 windows front and back and 2 on the side = 10 windows.

  • +

    How long should new windows last?

    Double glazing lasts for around 20 years but does vary depending on the quality of the window units and the quality of the installation.

    Reputable double glazing manufacturers and installers will offer guarantees (at Everest, we offer a standard 10-year guarantee on all windows and lifetime guarantees against internal condensation and discolouration*).

    Of course, windows can last far longer than their predicted lifetime and many houses have windows that are over thirty years old - if they've been well-maintained.

    The first part of the double glazed window that is likely to fail is the seal and second to that are the hinges.

    It also depends on where the windows are positioned in a property. For example, a south-facing window that gets a lot of sun and heat is more prone to discolouring or the seals drying out.

  • +

    Does double glazing increase the property value?

    House buyers in the UK rate double glazing and central heating at the top of their list when looking for a new home.

    Double glazing can increase the property value by up to 10% if the windows are of good quality and the style and colour are in keeping with the property. Therefore, an investment in new windows can pay back if you are thinking of selling.

    Beware though, the windows must suit the property and if you get this wrong you can decrease instead of increasing the value. For example, period properties suit timber frames and traditional sash windows. If you remove old sash windows to replace with uPVC double glazing you can devalue the house.

  • +

    Cheap double glazing windows or quality double glazing?

    Don't ever be fooled into thinking that cheap double glazing is a better option than paying more to install quality windows.

    As we highlighted above, fitting uPVC in a period property instead of timber can decrease the property value and turn off buyers.

    Poor quality double glazing can have a host of issues and you may also find that a cheap supplier has a cheap or non-existent guarantee. More importantly, only reputable well-established companies can offer a lifetime guarantee with the confidence they will be there in twenty years to replace a window if there is a problem.

    Cheap window companies are more likely to not be around to honour warranties when you need them.

    For any investment, you make in your home, quality should always take precedence over price. Trying to do anything on the cheap always turns out to be expensive in the long-term.

    Double glazing or triple glazing?

    Just when you got used to buying double glazed windows, along came triple glazed to throw another option into the equation.

    The benefits of triple glazed are:

    • Thermal efficiency - an extra pane of glass with more argon gas sandwiched between boosts the A+ rating to A++ and the highest rating a window can have. The result is a reduction in energy bills and a warmer house.
    • Soundproofing - acoustic glass can reduce sound by 40 dB and make a road seem four times further away.
    • Security - one more pane of glass to get through makes a window with serious resistance.

    The cost of triple glazing is 10-20% more than double glazing, but you can gain 20-30% more energy efficiency.

  • +

    What is the cost of secondary double glazing?

    As an alternative to double glazing, secondary glazing might be a more economical option to consider.

    Instead of replacing the full window, secondary glazing fits internally over your window recess to give a second layer of insulation over the window.

    Why would you choose secondary glazing over double glazing?

    • If you live in a period property or have a clause in your lease that stops you from replacing your single-glazed (usually sash) windows.
    • You want to retain the style of your original windows.
    • You want to eliminate draughts without the expense of new windows.
    • You want to reduce the noise if you live next to a busy road.
    • Secondary glazing is great for acoustics and can reduce external noise pollution by up to 80%.

    The cost of secondary glazing can be up to 50% less than installing double glazing new windows.

What should your cost of windows quote include?

When researching the average price for new windows from different suppliers make sure that you compare like-for-like.

Keep in mind that prices listed on a website don't reflect the full cost of windows and all the variables.

Ask your supplier to provide a full and transparent quote that lists everything that's included from the new windows cost to installation and any aftercare and warranties they offer.

You don't want to have the surprise of any hidden costs when you're half-way through a window installation.

What should be included in your cost of window quote:

  • A full technical survey of your property
  • The sizes, styles and colours of the frames
  • The materials to be used
  • Type of glass to be used
  • The window energy rating for the glass
  • Window furniture and handles
  • External window cills
  • Full installation including all fixings, trims and sealants
  • Disposal of your old windows

Most importantly, make sure you get a certificate to say your installer is registered with a competent person scheme, such as FENSA or Certass. This means that you have automatic approval for building regulations and don't need to apply yourself.

    Considering all factors, replacing old inefficient windows is worth the cost and a good investment."}},{"@type":"Question","name":"Should I replace all windows at once?","acceptedAnswer":{"@type":"Answer","text":"

    It is better to replace all windows at once.

    Firstly, because the aesthetic of the property looks better with uniformity. This will help the value of your property and make it more appealing to buyers.

    Secondly, it is far more cost-effective to replace all windows at the same time. Installers work on a basis of having fixed costs to attend a job. The more windows you have installed at once, the cheaper the cost per unit becomes.
