How we approach smoke vent rooflights (AOVs) in Southall
We handle smoke vent rooflights (AOVs) across Greater London, including Southall. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. In Southall, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
Neighbouring towns include Greenford (2 km) and Ealing (2 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Break-glass and smoke-detector triggers
- Service and test plans

Before you order: points to check
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Building control and safety duties in Southall
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 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 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 a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Can you work alongside my builder in Southall?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Southall?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
