How we approach smoke vent rooflights (AOVs) in Sheffield
Our smoke vent rooflights (AOVs) service in Sheffield 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.
Exposed Pennine and coastal towns in Yorkshire need upstand and flashing details built for wind-driven rain. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
Sheffield is the main town we list in South Yorkshire; we also cover nearby Rotherham and Dronfield.

Rules and responsibilities in Sheffield
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.

Common questions
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 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.
Can you work alongside my builder in Sheffield?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
