How much does a home extension cost in Tonbridge?

In Tonbridge, a home extension typically costs between £23,000–£80,500, depending on the project. South East costs typically run above the UK average — Kent labour and materials are a real factor. Price comes down to single vs double storey and floor area, foundations and structural work and planning, glazing and finish quality more than anything else. Getting two or three quotes is the best way to see a fair local price, which is exactly what our free matching service arranges.
