How much does a home extension cost in Crawley?

As a 2025 guide, most homeowners in Crawley pay somewhere between £23,000–£80,500 for a home extension. South East costs typically run above the UK average — West Sussex 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?

Plan for about 3–6 months of work for a home extension in Crawley, weather and approvals permitting.

  • 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.

Local guide

Home Extensions in Crawley: the 2025 guide

Why a home extension makes sense in Crawley

Across West Sussex, a thoughtfully designed home extension adds comfort day to day and appeal when it’s time to sell. A well-built extension typically adds both significant living space and long-term property value.

Planning your home extension in Crawley

Careful planning avoids the common pitfalls. Get a detailed quote, agree milestones, and don’t choose on price alone — the cheapest option often costs more in the long run. That’s why our vetting focuses on track record, not just rates.

Local know-how for Crawley

Crawley and the wider West Sussex area are known for tile-hung and flint cottages, Downland villages and coastal-town housing. The style of local homes matters for a home extension — south downs/aonb, conservation and coastal exposure are all common. A local specialist who knows Crawley will factor all of this into your quote and design.

Choosing the right Crawley professional

Choosing the right person is the hardest part. Rather than sifting through directories and reviews, Renomate does the legwork — we match you with a vetted Crawley specialist for your home extension, check their credentials, and introduce you personally.
