How much does a loft conversion cost in London?
Expect a loft conversion in London to cost roughly £32,000–£77,000, based on typical local projects. 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. What you pay depends mainly on conversion type (Velux, dormer, hip-to-gable, mansard) and staircase position and structural work, plus adding an ensuite or extra glazing. 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 London, expect a typical loft conversion to take about 6–10 weeks once work begins.
- Plan the staircase. Access takes space from the floor below — design it in early.
- Think about light. Rooflights and dormers dramatically change how the room feels.
- Budget for a contingency. Older roofs can hold surprises — keep 10–15% in reserve.

Planning your loft conversion in London
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 London
London and the wider Greater London area are known for Victorian and Georgian terraces, flat conversions and new-build apartments on tight urban plots.
