How much does a home extension cost in Marlborough?
A typical Marlborough home extension works out at about £20,000–£70,000 in 2025. South West costs are broadly around the national average — Wiltshire 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 Marlborough take around 3–6 months, depending on scope and specification.
- 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.
