Smoke vent rooflight installation in Catford

Our guide price for smoke vent rooflight installation starts from £3,595, and the real figure for your roof in Catford depends on a handful of things: the size and type of smoke vent rooflight, whether the opening exists already, the roof covering, and how easy access is. We fix the price in a written quote before work begins. Nothing gets added on the day without your say-so. For a rough idea first, photos and a couple of measurements are enough to go on, and we cover all of 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.

Fitting across Catford and nearby

Fitters travel to the job, so the address is what counts. In Catford that means postcode districts SE6, SE13 and SE4, and the same teams can just as easily take on work in Lewisham, about 1 mile away, or Brockley at roughly 1 mile. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

What we do on the day

  • Certified vent and actuator matched to the opening and controls
  • Controls, detection and wiring handled by the smoke-control specialist
  • Commissioning and sign-off carried out by the specialist before handover
  • Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.
  • Free area at the stair head — We check the free area the vent must provide before choosing a replacement.

What happens on the day

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, building control and Catford

A replacement smoke vent in England has to keep the free area and performance the building's fire strategy relies on, using a vent certified to BS EN 12101-2 with its actuator and backup power. We fit the vent and do the roof work; a smoke-control specialist connects and commissions the controls, and we confirm whether building control needs to be notified.

Before you get in touch

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, SE6 or nearby, confirms travel.

Common questions in Catford

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.

What if my roof opening is the wrong size for the smoke vent rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

Do you cover Catford?

Yes. Fitters travel to addresses in Catford and the surrounding districts, including SE6. 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.
