Smoke vent rooflight installation in Cardiff & the Vale

Before any smoke vent rooflight is fitted in Cardiff & the Vale, three measurements get checked: the builder's opening, the external size of the unit, and the upstand height above the finished roof, or the batten and tile details on a pitched roof. Get those right and the rest of the job follows. We handle smoke vent rooflight installation in every part of Cardiff & the Vale, with 3 towns listed on the site and the countryside between them covered too.

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 Cardiff & the Vale

Coverage in Cardiff & the Vale works by postcode, not by distance from an office. Give us the full postcode and we will confirm whether it is standard cover, as it is for most of Wales, or one of the few remote and island areas handled by arrangement. Either way, you get a written quote before any work is booked, with travel included in the price.

Included in the work

  • Old vent removed with the stairwell kept protected below
  • Upstand checked, adapted or rebuilt to the vent maker's drawing
  • New vent fitted, sealed and weathered into the roof
  • Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.
  • Free area at the stair head — We check the free area the vent must provide before choosing a replacement.

Rules that apply in Wales

In Wales, smoke vents must be certified products that keep the free area the building's fire strategy requires, with controls commissioned by a smoke-control specialist. Welsh guidance and building control set the detailed requirement for each building, and we confirm it before quoting.

Common questions in Cardiff & the Vale

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.

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 commercial rooflights need planning permission?

Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.
