Smoke vent rooflights (AOVs) in Warminster: what is involved?
Our smoke vent rooflights (AOVs) service in Warminster covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Warminster is around 48 km from Swindon, and we survey and fit throughout that part of Wiltshire, including the BA12 district.

Building control and safety duties in Warminster
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.

Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
