Underpinning ranges from £17,068 (Sean W Scott General Builder based in IP28) to £17,900 (Helenski Group Ltd based in IP24), but the final cost will depend on the method of underpinning used, how much of your foundations need underpinning and where you live.
Comparing extension builders estimates for underpinning gives you an idea of who will be better value but the best way to compare costs is to get actual quotes.
