How we approach smoke vent rooflights (AOVs) in Caterham
We handle smoke vent rooflights (AOVs) across Surrey, including Caterham. 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Caterham is around 34 km from Woking, and we survey and fit throughout that part of Surrey, including the CR3 district.
Specification options
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Control panel with battery backup
- Service and test plans
- Break-glass and smoke-detector triggers
- Servicing and testing available

What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- 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
Rules and responsibilities in Caterham
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.
Read the planning permission guide before you commit to a design.
