Loft Conversions

As a 2025 UK guide, a loft conversion typically costs between £25,000 and £60,000. The biggest factors are conversion type (Velux, dormer, hip-to-gable, mansard), staircase position and structural work, and adding an ensuite or extra glazing. These are guide figures only — the best way to get an accurate price is two or three quotes, which our free matching service arranges for you.

Most loft conversion projects take around 6–10 weeks on site, plus design time and any approvals beforehand. Your matched specialist will give you a firm schedule once they've seen the project.

Many loft conversions are permitted development, but dormers facing a road, mansards, and anything in a conservation area or on a listed building usually need planning permission. Building regulations always apply — covering fire safety, insulation and the staircase. Your specialist will confirm the route for your property.

As a rule of thumb you need around 2.2m of head height at the highest point for a comfortable, compliant conversion. If you're short on height, options like a dormer or hip-to-gable can create it. A specialist survey gives you a definite answer.

Loft conversions are among the best-value ways to add a bedroom and increase a home's worth, especially when they add an ensuite. They use space you already own, which is why the return is usually strong.
