What do smoke vent rooflights (AOVs) involve?
Our smoke vent rooflights (AOVs) service in Somerset covers automatic smoke ventilators at the head of stairwells and atria. We survey every job before fixing the price.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet.

Planning and building rules in England
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We install to the building's fire strategy and the manufacturer's certification.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.

Common questions
Do smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
Can you replace an old smoke vent?
Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.
Who is responsible for maintaining smoke vents?
The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Do you fit smoke vent rooflights (AOVs) across Somerset?
Yes. We survey and fit smoke vent rooflights (AOVs) across Somerset, including Bath, Weston-super-Mare, Taunton.
