How we approach smoke vent rooflights (AOVs) in Tonbridge
For Tonbridge 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Jobs in Tonbridge 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
- Glazed rooflight or louvred vent
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Glazed units bring daylight to stairwells
- Replacement of failed or obsolete units
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
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Building control and safety duties in Tonbridge
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.

Smoke vent rooflights (AOVs) in Tonbridge: questions
Do smoke vents need a control panel?
