How we approach smoke vent rooflights (AOVs) in Bexleyheath
For Bexleyheath homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
Neighbouring towns include Welling (2 km) and Bexley (2 km). We offer a survey date when we reply to your enquiry.

Building control and safety duties in Bexleyheath
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

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 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 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 fit smoke vent rooflights (AOVs) in Bexleyheath?
Yes. We survey and fit smoke vent rooflights (AOVs) in Bexleyheath and across Greater London. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Bexleyheath?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
