What home projects cost near you

Building prices differ by region, and every council sets its own building control charges. We cover 92 council areas in England and Wales (not every council yet). Pick your council to see local prices for extensions, lofts, kitchens and bathrooms, with that council’s own published fees.

Council not listed? We haven’t checked its building control charges yet, so there’s no page for it. The calculator still covers every UK postcode: it uses building prices for your region and a typical building control charge from the councils we checked. Your council’s own charge is on its website, usually under building control.
