Smoke vent rooflight installation in Northamptonshire

Across Northamptonshire we fit smoke vent rooflights for homeowners, builders, roofers and commercial clients. The trade side matters: an extension company with jobs running in several of the 7 towns we list does not want to coordinate a different fitter for each. We can take the rooflight element of every site, fitted to the maker's instructions and left ready for the next trade. Domestic customers get the same fitting standard, quoted in writing before work begins.

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.

Towns we list in Northamptonshire

Builders and roofers working in Northamptonshire can use us for the rooflight element of a job, wherever the site is in England. Homeowners can book us directly. In both cases the fitters come to the address, the work follows the maker's instructions, and a written quote fixes the price first. Fitting is carried out by vetted teams under S&K's direction.

What the job includes

  • Commissioning and sign-off carried out by the specialist before handover
  • Upstand checked, adapted or rebuilt to the vent maker's drawing
  • Controls, detection and wiring handled by the smoke-control specialist
  • Free area at the stair head — We check the free area the vent must provide before choosing a replacement.
  • Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.

Rules that apply 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.

Common questions in Northamptonshire

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.

Who is responsible for the smoke-control system?

The building's responsible person, duty holder or managing agent, depending on the nation, is responsible for keeping fire safety systems working. Our part is the rooflight and roof work; the controls, detection and commissioning are handled by a smoke-control specialist, and the quote says who does what.
