What do smoke vent rooflights (AOVs) involve?
Our smoke vent rooflights (AOVs) service in Worcestershire covers automatic smoke ventilators at the head of stairwells and atria. We survey every job before fixing the price.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. Midlands housing is a mix of Victorian terraces, inter-war semis and newer estates, and rear kitchen extensions with flat rooflights are a common upgrade.

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. Fire classification of rooflight materials near boundaries is checked at specification.

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.
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.
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 Worcestershire?
Yes. We survey and fit smoke vent rooflights (AOVs) across Worcestershire, including Worcester, Redditch, Kidderminster.
