Smoke vent rooflights (AOVs) in Crawley: what is involved?
For Crawley 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. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
We cover all of Crawley and the RH11 district, and nearby Horley and Horsham.
What you can choose
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Control panel with battery backup
- Glazed rooflight or louvred vent
- Break-glass and smoke-detector triggers
- Also usable for day-to-day ventilation
- Opens automatically on alarm signal
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
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Building control and safety duties in Crawley
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
Who is responsible for maintaining smoke vents?
The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
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.
Can you work alongside my builder in Crawley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit smoke vent rooflights (AOVs) in Crawley?
Yes. We survey and fit smoke vent rooflights (AOVs) in Crawley and across West Sussex. Send your postcode and we will offer a survey date when we reply.
