Smoke vent rooflights (AOVs) in Hounslow: what is involved?
Smoke vent rooflights (AOVs) in Hounslow means automatic smoke ventilators at the head of stairwells and atria. We cover the TW3 district and the rest of Greater London, with a survey before any price is fixed.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
Jobs in Hounslow 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 Hounslow
- Rain and wind sensors for daily vent use
- Control panel with battery backup
- Glazed rooflight or louvred vent
- Service and test plans
- Break-glass and smoke-detector triggers
- Replacement of failed or obsolete units
- Manual override at the fire service access level
Before you order: points to check
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- Whoever holds the building's fire-safety duties (the responsible person, the duty holder in Scotland or the appropriate person in Northern Ireland) must keep systems maintained and tested
Regulations for smoke vent rooflights (AOVs) in Hounslow
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.
See our building regulations guide for U-values, glazing limits and self-certification.

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.
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.
