How much does a home extension cost in St Albans?
In St Albans, 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 — Hertfordshire labour and materials are a real factor. What you pay depends mainly on single vs double storey and floor area and foundations and structural work, plus 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?
In St Albans, expect a typical home extension to take about 3–6 months once work begins.
- 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.
