How much does a home extension cost in Sevenoaks?

In Sevenoaks, 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. 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.

Figures are a 2025 guide only — your matched installer will give you an accurate, no-obligation quote.

How long does it take?

Allow roughly 3–6 months for a home extension in Sevenoaks, plus any design and approval time beforehand.

  • Check planning permission. Most larger projects need planning and building-regs approval — check early.
  • Hire a structural engineer. Essential where load-bearing walls are removed, for safety and compliance.
  • Plan for the long term. Design for how you’ll use the space in five and ten years, not just now.
