How much does a home extension cost in Hillingdon?

A home extension in Hillingdon usually falls in the £25,500–£89,500 range, though every project is different. London is the most expensive part of the UK for building work, well above the national average — Greater London 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 Hillingdon 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.
  • 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.
