Smoke vent rooflights (AOVs) in Bushey: what is involved?
For Bushey homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
From Bushey to Watford, Borehamwood and Harrow, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Bushey
- Rain and wind sensors for daily vent use
- Glazed rooflight or louvred vent
- Service and test plans
- Break-glass and smoke-detector triggers
- Electric (24 V) or pneumatic actuation
- Manual override at the fire service access level
- Also usable for day-to-day ventilation
What to check first
- 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
- Replacing a vent with a non-equivalent product can affect the fire strategy
Regulations for smoke vent rooflights (AOVs) in Bushey
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.

Questions about smoke vent rooflights (AOVs) in Bushey
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.
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 work alongside my builder in Bushey?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Bushey?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
