These days very few homes can do without double glazing. Unless you live in a listed building, conservation area or simply prefer lighting a warm fire to deal with those cold draughts from your windows, then double glazing is the best way to keep you and your family warm and your home well insulated – all year round!

Double glazing comes in a range of different styles, sizes, shapes and patterns, so to try and summarise costs is tricky. If you aren’t looking for anything too out of the ordinary, however, then this tabulated price guide should be able to help you decide whether or not double glazing is the right investment for you at this moment in time – just make sure you budget carefully before signing with any company or contractor.

Window Size (mm) Cost (£) Per Window
530 x 780 £275
550 x 980 £300
780 x 1,180 £350
940 x 1,600 £450
980 x 1,340 £450


It should also be noted that these prices don’t include labour charges – so don’t get ahead of yourself and book double glazing installation without asking about exact costs first. To get the best deal you should also try comparing a number of different quotes, from both major companies to local businesses.  Don’t be afraid to ask about things like insurance or guarantees either – just as with any business transaction, you want to be sure you’re getting what you pay for.
