What do smoke vent rooflights (AOVs) in Doncaster involve?
Smoke vent rooflights (AOVs) in Doncaster means automatic smoke ventilators at the head of stairwells and atria. We cover the DN1 district and the rest of South Yorkshire, with a survey before any price is fixed.
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.
Doncaster sits about 2 km from Bentley and 18 km from Rotherham, and we cover the whole DN1 postcode district and the roads in between.
What you can choose
- Glazed rooflight or louvred vent
- Break-glass and smoke-detector triggers
- Rain and wind sensors for daily vent use
- Service and test plans
- Electric (24 V) or pneumatic actuation
- Manual override at the fire service access level
- Opens automatically on alarm signal
What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- 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
Building control and safety duties in Doncaster
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
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
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.
Do I need to be at home for the survey in Doncaster?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
