Considering a home extension? The below calculator uses the latest data from the Office of National Statistics, looking at property prices per square metre in England and Wales, and will show you how much an extension could add to your home. Perhaps you want to extend your kitchen or bathroom or add an extra bedroom? Let us know where you live and the size of extension you’re looking to add and we’ll help you work out how much an extension could add to the value of your home.

It’s important to remember that the value an extension could add to your home will vary depending on a number of factors from the quality of construction, to the type of room (e.g. whether it’s a kitchen extension or adding an extra bedroom) and the exact location of your property. This calculator provides an indication of how much you could add to your property by utilising the average value of houses across local authority areas.
