Guide ranges for supply & fit; controls and commissioning by a smoke-control specialist. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.
Where our fitters travel
Covering Wembley means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in HA0, HA9 and UB6, and are happy to quote further out in Brent and Harlesden. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.
What the job includes
- Certified vent and actuator matched to the opening and controls
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- Old vent removed with the stairwell kept protected below
- Certified as a system — We only fit smoke vents that are certified to BS EN 12101-2.
- Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.
From arrival to clean-up
Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a smoke vent rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.
Planning and building rules in England
In England, smoke vents for common stairs must be certified to BS EN 12101-2, provide the free area the fire strategy requires (Approved Document B calls for at least 1 m² at the top of a common stair), and have backup power. Smoke vents have their own energy limit, commonly 3.5 W/m²K. Controls and commissioning are handled by a smoke-control specialist, and building control is involved where the system changes.
Before you get in touch
What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around HA0 and we will come back with a quote or a survey date.
Common questions in Wembley
How long does fitting take?
Fitting a smoke vent rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
Does commercial rooflight work need building control?
Usually. New openings, structural changes and smoke vents go through building control, and on buildings covered by fire safety law that means a full plans application rather than a building notice. We are not registered with a competent person scheme, so replacements we fit are notified to building control. We confirm the route and show any fee on the quote.
Do you need scaffolding to fit a rooflight?
Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
