About DoubleGlazing.com
An independent guide to replacing windows and doors in a UK home: what each kind looks like, what it costs fitted, and how to find a good installer.
Most window and door websites belong to a company that sells them, so none of them tells you the price. We do. Every product on this site shows what it typically costs fitted, including VAT, with the range most people pay and the things that push a quote up or down.
We don't make or fit windows. That lets us compare uPVC with aluminium and timber, or a national brand with a local FENSA installer, without a reason to prefer one.
Where the numbers come from
Guide prices are compiled from published UK price guides and trade sources, each one cited on the page it supports. They are indicative ranges, not quotations, and they are rounded so that nobody mistakes them for a quote. Regional prices scale the UK figure by local labour rates. Our pricing methodology sets out how all of it is put together.
Who writes it
John B edits the guides and checks the price data. Every page carries a byline and a last-reviewed date.
How we make money
The site is published by Leads Do Work Ltd, which runs the quote service on it. When you request quotes, installers who cover your area pay us for the introduction, and some pages carry adverts. You pay nothing and you are under no obligation to accept any quote. Neither has any bearing on the prices we publish or the advice we give: see how we make money.
If we get something wrong
Tell us. The report a price form comes straight to us, and a report from someone who has just had the work done is the most useful thing we receive.
