Smoke vent rooflight installation in Kensington

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for smoke vent rooflight installation in Kensington, internal finishing is listed so you can see whether it is included or left for your decorator. That way a smoke vent rooflight looks right from the room below as well as from outside. We cover Kensington and properties throughout Greater London.

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.

Coverage in and around Kensington

Jobs across W8, SW5 and SW7 are part of our normal cover for Kensington. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Bayswater and Notting Hill are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Included in the work

  • Certified vent and actuator matched to the opening and controls
  • Old vent removed with the stairwell kept protected below
  • Upstand checked, adapted or rebuilt to the vent maker's drawing
  • 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.

What happens on the day

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a smoke vent rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one to two days per vent.

Planning, building control and Kensington

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.

What to send for a quick quote

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 W8 and we will come back with a quote or a survey date.

Common questions in Kensington

What upstand height and roof pitch does smoke vent rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.

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 cover Kensington?

Yes. Fitters travel to addresses in Kensington and the surrounding districts, including W8. 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.
