Loft conversion costs
The cost of a loft conversion depends mostly on the type of conversion, the size of the roof space and the finish you want. We price every loft from a survey.
What affects the price.
Conversion type
A rooflight conversion needs far less structure than a dormer, hip-to-gable or mansard.
Head height and roof shape
Low ridges or complex roofs may need more structural work.
Staircase position
Where the new stair lands affects the floor below.
Bathroom
An en-suite adds plumbing, waterproofing and fittings.
Planning route
Permitted Development or full planning, depending on your property and borough.
Access
Scaffolding, parking and how materials reach the roof.
