Smoke vent rooflights (AOVs) in Maidstone: what is involved?
Our smoke vent rooflights (AOVs) service in Maidstone covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Maidstone is the main town we list in Kent; we also cover nearby Chatham and Rochester.
What you can choose
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Glazed rooflight or louvred vent
- Break-glass and smoke-detector triggers
- Service and test plans
- Glazed units bring daylight to stairwells
- Also usable for day-to-day ventilation
Things we check at survey
- Replacing a vent with a non-equivalent product can affect the fire strategy
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Building control and safety duties in Maidstone
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.

Common questions
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.
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.
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 you work alongside my builder in Maidstone?
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 Maidstone?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
