How much does a loft conversion cost in Merton?
A typical Merton loft conversion works out at about £32,000–£77,000 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. The biggest cost drivers are conversion type (Velux, dormer, hip-to-gable, mansard), staircase position and structural work, and 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?
A loft conversion in Merton usually takes 6–10 weeks, though planning and material lead times can affect the schedule.
- Consider building regs. Fire safety, insulation and stairs must meet regulations.
- 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.
