How we approach smoke vent rooflights (AOVs) in Chelsea
We handle smoke vent rooflights (AOVs) across Greater London, including Chelsea. 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.
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 communal stairwells, corridors and atria.
Chelsea sits about 2 km from Battersea and 2 km from Wandsworth, and we cover the whole SW10 postcode district and the roads in between.
Options we can specify in Chelsea
- Rain and wind sensors for daily vent use
- Break-glass and smoke-detector triggers
- Control panel with battery backup
- Service and test plans
- Electric (24 V) or pneumatic actuation
- Glazed units bring daylight to stairwells
- Manual override at the fire service access level
What to check first
- Replacing a vent with a non-equivalent product can affect the fire strategy
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Building control and safety duties in Chelsea
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.
