Smoke vent rooflights (AOVs) in Northolt: what is involved?
Thinking about smoke vent rooflights (AOVs) in Northolt? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Jobs in Northolt are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Northolt
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers

What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Rules and responsibilities in Northolt
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

Questions about smoke vent rooflights (AOVs) in Northolt
Who is responsible for maintaining smoke vents?
The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
Do smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
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.
Do I need to be at home for the survey in Northolt?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Northolt?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
