Smoke vent rooflights (AOVs) in Eltham: what is involved?
Our smoke vent rooflights (AOVs) service in Eltham 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. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Eltham is around 14 km from central London, and we survey and fit throughout that part of Greater London, including the SE9 district.

Things we check at survey

- Smoke ventilation is designed to the building's fire strategy — we install to that design
Rules and responsibilities in Eltham
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. Fragile-roof safety and access are planned before work starts.

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.
