How much does a home extension cost in Brentwood?
In Brentwood, a home extension typically costs between £21,000–£74,000, depending on the project. Costs in the East of England sit a touch above the national average, especially nearer London — Essex 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?
Typical Brentwood home extensions timescales run to about 3–6 months on site.
- Check planning permission. Most larger projects need planning and building-regs approval — check early.
- Match your materials. Choose brick and finishes that harmonise with your existing home.
- Plan for the long term. Design for how you’ll use the space in five and ten years, not just now.

Why a home extension makes sense in Brentwood
Demand for quality home improvement in Essex keeps growing, and a home extension in Brentwood can transform how you use your space. A well-built extension typically adds both significant living space and long-term property value.
Planning your home extension in Brentwood
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 Brentwood
The housing across Essex spans weatherboarded cottages, interwar and postwar estates and commuter new-builds. That mix shapes how a home extension is approached here — fast estate growth meets estuary flood zones across the south of the county. A local specialist who knows Brentwood will factor all of this into your quote and design.
