Smoke vent rooflights (AOVs) in March: what is involved?
Our smoke vent rooflights (AOVs) service in March 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.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
March is around 23 km from Peterborough, and we survey and fit throughout that part of Cambridgeshire, including the PE15 district.

- Break-glass and smoke-detector triggers

Before you order: points to check
- 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
Rules and responsibilities in March
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.
Read the planning permission guide before you commit to a design.

Questions about smoke vent rooflights (AOVs) in March
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.
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.
