Smoke vent rooflights (AOVs) in Norfolk: the essentials
Our smoke vent rooflights (AOVs) service in Norfolk covers automatic smoke ventilators at the head of stairwells and atria. We survey every job before fixing the price.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights. Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows.

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
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
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.
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.
Do you fit smoke vent rooflights (AOVs) across Norfolk?
Yes. We survey and fit smoke vent rooflights (AOVs) across Norfolk, including Norwich, Great Yarmouth, King's Lynn.
