What do smoke vent rooflights (AOVs) in Deal involve?
Smoke vent rooflights (AOVs) in Deal means automatic smoke ventilators at the head of stairwells and atria. We cover the CT14 district and the rest of Kent, with a survey before any price is fixed.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
Jobs in Deal are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Building control and safety duties in Deal
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.
Read the planning permission guide before you commit to a design.

Common questions
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
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 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.

Yes. We survey and fit smoke vent rooflights (AOVs) in Deal and across Kent. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Deal?
