How we approach smoke vent rooflights (AOVs) in New Malden
We handle smoke vent rooflights (AOVs) across Greater London, including New Malden. 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 London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
New Malden is around 15 km from central London, and we survey and fit throughout that part of Greater London, including the KT3 district.
What you can choose
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Service and test plans
- Rain and wind sensors for daily vent use
- Glazed rooflight or louvred vent
- Replacement of failed or obsolete units
- Manual override at the fire service access level
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
Building control and safety duties in New Malden
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.

Smoke vent rooflights (AOVs) in New Malden: questions
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.

Many dual-purpose units also open for daily ventilation, closing automatically in rain.
