Windows and Doors Cost Calculator FAQ

The cost of a new window in the UK ranges from £160-£2000 per window. Casement windows usually cost between £160 to £1,240. Sash windows cost from £240 to £1,860 and tilt and turn windows cost between £200 to £1,550. However, costs will vary based on chosen materials, customisations and window glazing. With our handy window installation cost calculator, you will know how much to expect to pay for your window installation. 

There are technically no grants specifically for new windows, but there are some incentives and schemes for glazing upgrades and draught-proofing as this meets the criteria for many energy-saving and eco-friendly policies. To find these schemes, you can contact your local council or look on their website for more information.
It is more cost-efficient to have all of your windows replaced at the same time rather than individually. It will also save time when making home upgrades. However, our window cost calculator will tell you exactly how much you should expect to pay for windows on your project.
House windows usually have a lifespan of 15–20 years. Once they begin to age, the seals begin to weaken or fail, which leaves you open to drafts and water seepage. If you have a single pane window, they will age faster as they are not as robust.
If you are choosing to upgrade your windows from single to double glazed panels then it is possible that you can see a reduction in your heating bills as double glazing helps to keep heat in and cold out meaning that you will use less energy to heat your home.
