How we approach smoke vent rooflights (AOVs) in Gosport
For Gosport 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. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Jobs in Gosport 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
- Control panel with battery backup
- Rain and wind sensors for daily vent use
- Break-glass and smoke-detector triggers
- Glazed rooflight or louvred vent
- Electric (24 V) or pneumatic actuation
- Servicing and testing available
- Opens automatically on alarm signal
Before you order: points to check
- 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
Rules and responsibilities in Gosport
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.
Read the planning permission guide before you commit to a design.

Questions about smoke vent rooflights (AOVs) in Gosport
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.
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 a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Can you work alongside my builder in Gosport?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Gosport?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
