What do smoke vent rooflights (AOVs) in Clifton involve?
Smoke vent rooflights (AOVs) in Clifton means automatic smoke ventilators at the head of stairwells and atria. We cover the BS8 district and the rest of Bristol, with a survey before any price is fixed.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Clifton is around 2 km from Bristol, and we survey and fit throughout that part of Bristol, including the BS8 district.
What you can choose
- Electric (24 V) or pneumatic actuation
- Rain and wind sensors for daily vent use
- Glazed rooflight or louvred vent
- Break-glass and smoke-detector triggers
- Service and test plans
- Opens automatically on alarm signal
- 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
- Replacing a vent with a non-equivalent product can affect the fire strategy
Rules and responsibilities in Clifton
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 Clifton
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
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 Clifton?
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 Clifton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
