How much does a home extension cost in Islington?
A typical Islington home extension works out at about £25,500–£89,500 in 2025. 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. Expect single vs double storey and floor area and planning, glazing and finish quality to move the price most, along with foundations and structural work. 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 Islington, 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.
- Set a clear budget. Allow a 10–15% contingency for unforeseen costs during the build.
