How much does a loft conversion cost in Thornbury?
A loft conversion in Thornbury usually falls in the £25,000–£60,000 range, though every project is different. South West costs are broadly around the national average — Gloucestershire labour and materials are a real factor. Price comes down to conversion type (Velux, dormer, hip-to-gable, mansard), staircase position and structural work and adding an ensuite or extra glazing 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.

- Check your head height. You generally need 2.2m at the highest point for a usable conversion.
- Consider building regs. Fire safety, insulation and stairs must meet regulations.
- Think about light. Rooflights and dormers dramatically change how the room feels.
