Loft Conversions in Hanwell
Dormer, hip-to-gable, mansard or a simple Velux conversion — including the staircase, the fire-rated doors and the building control certificate that makes it count as a bedroom when you sell.
A loft is only a bedroom if it is signed off as one. That means head height, a protected escape route, fire doors on the landing, mains-wired interlinked alarms and floor joists sized for living load rather than storage. We see plenty of conversions done without any of it, and they become a problem at survey. Every conversion we do goes through building control from the start.
Loft Conversions in Hanwell: what to know locally
Victorian and Edwardian terraces and semis, with 1930s housing towards Boston Manor and larger properties near Churchfields.
Hanwell sits on relatively generous plots for the price point, which makes it good ground for rear extensions and loft conversions on properties where the budget would not stretch in Ealing or Chiswick. Older stock often has solid walls and benefits from external insulation.
Planning authority: Ealing Council. Parts of Hanwell including the Golden Manor and Churchfields areas carry conservation designation. The Victorian stock frequently has solid walls, making external wall insulation worth considering alongside other work.
What the work covers
- Structural floor joists and steel beams
- Dormer construction or roof reconfiguration
- Staircase design and installation
- Fire doors, protected escape route and interlinked alarms
- Insulation to current regs, electrics and heating
- En-suite plumbing where wanted
What it costs
A dormer conversion with an en-suite typically runs £55,000 to £85,000 in West London. Velux-only conversions are considerably less; mansards more. The roof structure drives the price more than the floor area does.

Loft Conversions in Hanwell — questions
Do you cover Hanwell?
Yes — Hanwell and the W7 postcodes are part of our core working area, along with Ealing, Greenford, Acton. Being local means a site visit within days rather than weeks.
Which council handles planning for Hanwell?
Ealing Council. Parts of Hanwell including the Golden Manor and Churchfields areas carry conservation designation. The Victorian stock frequently has solid walls, making external wall insulation worth considering alongside other work.
Is my loft tall enough to convert?
You want roughly 2.2 metres from the floor joists to the ridge before work starts. Below that it can still be possible by lowering ceilings below or altering the roof, but it changes the job substantially. We measure on the first visit.
Do I need planning permission for a loft conversion?
Rear dormers often sit within permitted development, subject to volume limits of 40 cubic metres for terraces and 50 for semis and detached. Anything facing a highway, or in a conservation area, usually needs an application.
Does a loft conversion need building regulations approval?
Always. Structure, fire escape, insulation and stairs are all covered. Without the certificate your conveyancer will flag it as an unsigned-off room when you come to sell, which costs you more than the sign-off would have.
