How much does a home extension cost in Bromley?

In Bromley, a home extension typically costs between £25,500–£89,500, depending on the project. London is the most expensive part of the UK for building work, well above the national average — Greater London labour and materials are a real factor. The biggest cost drivers are single vs double storey and floor area, foundations and structural work, and planning, glazing and finish quality. Getting two or three quotes is the best way to see a fair local price, which is exactly what our free matching service arranges.
