Smoke vent rooflights (AOVs) for Chiswick: the essentials
Our smoke vent rooflights (AOVs) service in Chiswick 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
We work across Greater London, including Chiswick, and in neighbouring towns such as Hammersmith and Acton. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Glazed rooflight or louvred vent
- Control panel with battery backup

What to check first
- Replacing a vent with a non-equivalent product can affect the fire strategy
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Rules and responsibilities in Chiswick
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.
Our planning guide covers each nation in more detail.
