What do smoke vent rooflights (AOVs) in Enfield involve?
Our smoke vent rooflights (AOVs) service in Enfield 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.
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.
From Enfield to Edmonton, Tottenham and Wood Green, the same survey-first process applies: measure, specify, fix the price, then fit.

- Replacing a vent with a non-equivalent product can affect the fire strategy
Building control and safety duties in Enfield
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.
Our planning guide covers each nation in more detail.

Smoke vent rooflights (AOVs) in Enfield: questions
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.

Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
