How we approach smoke vent rooflights (AOVs) in Dewsbury
Our smoke vent rooflights (AOVs) service in Dewsbury 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.
Many Yorkshire homes have had kitchen extensions with flat roofs, where a larger glass rooflight is a straightforward upgrade from an old dome. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
Dewsbury is around 13 km from Leeds, and we survey and fit throughout that part of West Yorkshire, including the WF12 district.

Rules and responsibilities in Dewsbury
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.

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.
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 smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
Do I need to be at home for the survey in Dewsbury?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Dewsbury?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
