Smoke vent rooflights (AOVs) in Tottenham: what is involved?
We handle smoke vent rooflights (AOVs) across Greater London, including Tottenham. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
Jobs in Tottenham 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.
What you can choose
- Break-glass and smoke-detector triggers
- Glazed rooflight or louvred vent
- Service and test plans
- Control panel with battery backup
- Rain and wind sensors for daily vent use
- Opens automatically on alarm signal
- Glazed units bring daylight to stairwells
Things we check at survey
- Replacing a vent with a non-equivalent product can affect the fire strategy
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Rules and responsibilities in Tottenham
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Smoke vent rooflights (AOVs) in Tottenham: 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 a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.

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