How much does double glazing cost?

The cost of fitting new double glazing windows is high up on my people's heads, so it's worth taking a brief look at the costs involved.

The cost of double glazing depends on the number of windows you need, their size and style, the frame's material and the installer you choose. A straightforward uPVC casement window will usually cost considerably less than a large bay window or bespoke aluminium installation.

That's why comparing like-for-like quotes matters. Prices can vary between installers even when the spec looks remarkably similar.

1-3 windows

Homeowners requesting 3 uPVC windows typically receive quotes between:

£1,200 - £2,500

For smaller replacement jobs

Whole house

Homeowners requesting 8 uPVC windows typically receive quotes around:

£4,500 - £8,000

For a typical 3-bedroom home

Doors + windows

Homeowners needing fully fitted windows and doors throughout the home typically receive quotes around:

£6,000 - £10,000+

For a broader home upgrade

Top tip:
Get at least three like-for-like quotes. The cheapest quote isn’t necessarily the best value if the specification, fitting or guarantee differs.

Is it worth getting more than one double glazing quote?

Usually, yes. Double glazing isn't an off-the-shelf purchase. Two installers can quote quite different prices for essentially the same job.

Comparing several quotes doesn't simply help you find the lowest price. It gives you a better idea of what a reasonable price looks like — and makes differences in guarantees, materials and installation clearer.
