How much does a home extension cost in High Wycombe?

A home extension in High Wycombe usually falls in the £23,000–£80,500 range, though every project is different. South East costs typically run above the UK average — Buckinghamshire labour and materials are a real factor. What you pay depends mainly on single vs double storey and floor area and foundations and structural work, plus 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.
