How much does a home extension cost in Slough?

In Slough, a home extension typically costs between £23,000–£80,500, depending on the project. South East costs typically run above the UK average — Berkshire labour and materials are a real factor. Price comes down to single vs double storey and floor area, foundations and structural work and planning, glazing and finish quality more than anything else. 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?

Most home extensions projects in Slough take around 3–6 months, depending on scope and specification.

  • 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 Slough: the 2025 guide

Why a home extension makes sense in Slough

With south east costs typically run above the uk average, a well-planned home extension in Slough can offer strong value for money. A well-built extension typically adds both significant living space and long-term property value.

Planning your home extension in Slough

Before you start, plan properly: set a realistic budget with a 10–15% contingency, confirm exactly what’s included in each quote, and check whether any permissions or building-regulations approvals apply. A good Slough specialist will guide you through this.

Local know-how for Slough

The housing across Berkshire spans mock-Tudor and Victorian villas, riverside homes and newer executive housing in an affluent commuter belt. That mix shapes how a home extension is approached here — high property values, plus thames-side flood zones in places, reward careful design. A local specialist who knows Slough will factor all of this into your quote and design.
