The cost of installing a new window varies depending on several different factors. Some general considerations include the frame material (wooden or PVC), the size of the window, and if you need to remove the old window and frame.

For a wooden frame, you’ll need to factor in the cost of the lumber, as well as the cost of labor if you don’t want to do it yourself. For PVC, you’ll just need to buy the window and install it yourself.

If you’re cutting in a new window, you’ll need to account for the cost of materials (lumber and screws), as well as labor if needed. If you’re replacing an existing window, you may need to hire a professional to do the job, which will add to the overall cost.

If you’re building a new structure, or if the window requires scaffolding, you’ll need to factor in the cost of the scaffolding and any additional labor needed.

Finally, there are the costs of the windows themselves. Depending on the type or style you choose, they can range from £80 to over £1,750.

uPVC Window Installation Cost

The cost of windows depends on the primary material you select. The most familiar type in UK residences today are uPVC windows (unplasticized polyvinyl chloride), a sort of plastic.

The word “Velux” is technically a brand name, but it has become synonymous with roof windows – windows in a roof or ceiling. A new Velux window installation will cost you £750-£1,750, depending on the size and type of window.

To give you an idea of sash windows, those typically cost between £1,500 (softwoods) to more than £2,000 (hardwoods).

You have a few options when it comes to installing your windows: you can buy them directly from a national company, which will provide and install the windows, or you can go with a smaller local business that will just get the windows for you.

A tip for discernment is to see if the company is associated with national organizations like FENSA or CERTASS. These groups work to advance the industry’s standards and promote only qualified tradespeople.

Although the double-glazing sales industry has changed over the years, it’s still important to be cautious of high-pressure sales tactics or time-sensitive offers that seem unrealistically good. You should never feel pressured into making a large purchase like new windows or get rushed into making choices you wouldn’t normally make.

Why Install New Windows?

Whilst the cost of installing new windows may discourage some people initially, it is worth considering the benefits that your new windows will bring to your home:

  • Bills: according to the Energy Saving Trust, by swapping your old single-glazed windows with new B-rated double glazing windows, you could shave around £165 per year off your energy bills. And if double glazing is too expensive, consider secondary glazing, which is still estimated to save you £100 per year on bills.

FAQs on New Window Fitting

What is a window fitting?

Window fitters or Windows Installers install windows, doors, conservatories as well as sash windows for buildings and structures. The team can be involved in the renovation and repair of existing homes, renovating old fittings, and restoring historic buildings.

Can I fit a window myself?

Yes, it’s possible. However, be aware that installing new window replacements is a skilled trade that can damage a wall and/or invalidate a manufacturer’s warranty.

How long do new windows typically last?

Windows, if well-maintained, can last for much longer than the manufacturer’s predicted lifespan. Many homes in the UK have windows that are over thirty years old.

The positioning of a home’s windows also contributes to how well they hold up over time. Windows that face south and get a lot of sunlight and heat are more likely to discolor or have the seals dry out, for instance.
