How we approach smoke vent rooflights (AOVs) in Holloway
Our smoke vent rooflights (AOVs) service in Holloway 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. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Neighbouring towns include Highbury (2 km) and Camden Town (2 km). We offer a survey date when we reply to your enquiry.

What to check first
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Rules and responsibilities in Holloway
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about smoke vent rooflights (AOVs) in Holloway
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.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
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 work alongside my builder in Holloway?
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 Holloway?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
