Smoke vent rooflights (AOVs) in Streatham: what is involved?
Smoke vent rooflights (AOVs) in Streatham means automatic smoke ventilators at the head of stairwells and atria. We cover the SW16 district and the rest of Greater London, with a survey before any price is fixed.
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. In Streatham, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
Neighbouring towns include Balham (2 km) and Clapham (4 km). We offer a survey date when we reply to your enquiry.
Specification options
- Glazed rooflight or louvred vent
- Control panel with battery backup
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Service and test plans
- Replacement of failed or obsolete units
- Also usable for day-to-day ventilation
Things we check at survey
- 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 Streatham
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We install to the building's fire strategy and the manufacturer's certification.
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.

Smoke vent rooflights (AOVs) in Streatham: 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.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
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.
