Loft conversion prices by type for 2026, including VAT, with London figures, the fees and extras a builder's quote leaves out, and when planning permission applies.
When a loft conversion needs planning permission in England, the 40 and 50 cubic metre limits for dormers, what a certificate costs, and the rules in Wales, Scotland and Northern Ireland.
What a dormer loft conversion costs in 2026, the dormer types, whether your loft has the height, the planning and building regulations rules in each nation, and how long it takes.
Usually not. Most fall under permitted development if you stay within 40 cubic metres for a terrace or 50 for a semi or detached, do not go above the existing roof ridge, and use materials in keeping. Mansards and anything on a flat or in a conservation area normally do need permission.
Six to eight weeks for a dormer once work starts, plus four to eight weeks beforehand for drawings, structural calculations and building control. Scaffolding usually goes up a week ahead.
