What do smoke vent rooflights (AOVs) in Brentwood involve?
For Brentwood 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.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
From Brentwood to Billericay, Hornchurch and Romford, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Electric (24 V) or pneumatic actuation
- Service and test plans
- Glazed rooflight or louvred vent
- Break-glass and smoke-detector triggers
- Control panel with battery backup
- Also usable for day-to-day ventilation
- Servicing and testing available
Before you order: points to check
- Replacing a vent with a non-equivalent product can affect the fire strategy
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Rules and responsibilities in Brentwood
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Questions about smoke vent rooflights (AOVs) in Brentwood
Can you replace an old smoke vent?
Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.
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.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Can you work alongside my builder in Brentwood?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Brentwood?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
