How much does a home extension cost in Croydon?

A home extension in Croydon 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?

Once started, expect around 3–6 months for a Croydon home extension.

  • Hire a structural engineer. Essential where load-bearing walls are removed, for safety and compliance.
  • Match your materials. Choose brick and finishes that harmonise with your existing home.
  • Set a clear budget. Allow a 10–15% contingency for unforeseen costs during the build.

Local guide

Home Extensions in Croydon: the 2025 guide

Why a home extension makes sense in Croydon

A home extension lets Croydon families stay in the area they love while gaining the space they need. A well-built extension typically adds both significant living space and long-term property value.

Planning your home extension in Croydon

Think through how you’ll use the space long term, agree a written scope and schedule, and check insurance and guarantees — the fundamentals that keep a Croydon project on track.

Local know-how for Croydon

Homes in and around Croydon include Victorian and Georgian terraces, flat conversions and new-build apartments on tight urban plots. Those property types influence the best way to plan a home extension — party-wall agreements, borough-specific planning and widespread conservation areas all apply. A local specialist who knows Croydon will factor all of this into your quote and design.
