What do smoke vent rooflights (AOVs) in Wallington involve?
Smoke vent rooflights (AOVs) in Wallington means automatic smoke ventilators at the head of stairwells and atria. We cover the SM6 district and the rest of Greater London, with a survey before any price is fixed.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Wallington is around 16 km from central London, and we survey and fit throughout that part of Greater London, including the SM6 district.

Building control and safety duties in Wallington
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.
