How much does a home extension cost in Harlow?

For a home extension in Harlow, a realistic budget is around £21,000–£74,000. Costs in the East of England sit a touch above the national average, especially nearer London — Essex labour and materials are a real factor. Expect single vs double storey and floor area and planning, glazing and finish quality to move the price most, along with foundations and structural work. 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 Harlow, 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.

Local know-how for Harlow
