How much does a home extension cost in Letchworth?

Budgets for a home extension in Letchworth generally land between £21,000–£74,000. Costs in the East of England sit a touch above the national average, especially nearer London — Hertfordshire 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.

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

How long does it take?

A home extension in Letchworth usually takes 3–6 months, though planning and material lead times can affect the schedule.

  • Check planning permission. Most larger projects need planning and building-regs approval — check early.
  • Plan for the long term. Design for how you’ll use the space in five and ten years, not just now.
  • Set a clear budget. Allow a 10–15% contingency for unforeseen costs during the build.
