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.
Is your address covered?
If you also own a property or a business unit in Sutton, Ewell or Epsom, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and SM7, KT17 and KT18 sit comfortably within that pattern.
Included in the work
- Controls, detection and wiring handled by the smoke-control specialist
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- New vent fitted, sealed and weathered into the roof
- 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.
Fitting your smoke vent rooflight, step by step
On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a smoke vent rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.
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.
Getting a price from photos
Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, SM7 or nearby, confirms travel.
Common questions in Banstead
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.
Do you cover Banstead?
Yes. Fitters travel to addresses in Banstead and the surrounding districts, including SM7. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
How does payment work?
Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
