Replacement costs: what to expect

The average cost for the supply and installation of one roof window is between £1200 and £1600. This cost is a broad average - your exact replacement quote will depend on the size and specification of your roof window. Speak to a member of our team to determine the best options for your lifestyle and budget.

With 12-months 0% interest credit, you can get more comfort and more daylight for less than you’d expect.

When you balance the costs, it starts to look like a good investment. Older roof windows can start to lose their edge - a little more draughty, a little less efficient. A straightforward replacement means your home stays comfortable year-round, and your heating bill isn't working overtime to compensate.
