What are smoke vent rooflights (AOVs)?
Smoke vent rooflights (AOVs) in West Yorkshire means automatic smoke ventilators at the head of stairwells and atria. Every quote follows a survey of the roof and the room below.
Stone-built terraces are common across Yorkshire, and roof windows in the rear slope are a popular way to light attic rooms. Conservation areas and stone villages across Yorkshire often call for conservation rooflights in slate or stone-slate roofs.

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 supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
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
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.
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.
Do you design the smoke strategy?
No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
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 West Yorkshire?
Yes. We survey and fit smoke vent rooflights (AOVs) across West Yorkshire, including Leeds, Bradford, Huddersfield.
