How much does a home extension cost in Guildford?

In Guildford, a home extension typically costs between £23,000–£80,500, depending on the project. South East costs typically run above the UK average — Surrey 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.

  • Check planning permission. Most larger projects need planning and building-regs approval — check early.
