Smoke vent rooflights (AOVs) in Canterbury: what is involved?
We handle smoke vent rooflights (AOVs) across Kent, including Canterbury. 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
Jobs in Canterbury 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.
Options we can specify in Canterbury
- Break-glass and smoke-detector triggers
- Electric (24 V) or pneumatic actuation

Things we check at survey
- Replacing a vent with a non-equivalent product can affect the fire strategy
- 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
Regulations for smoke vent rooflights (AOVs) in Canterbury
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.
