Smoke vent rooflights (AOVs) in Northamptonshire: the essentials
Across Northamptonshire, our smoke vent rooflights (AOVs) work covers automatic smoke ventilators at the head of stairwells and atria. Survey first, fixed price second, fitting third.
Midlands housing is a mix of Victorian terraces, inter-war semis and newer estates, and rear kitchen extensions with flat rooflights are a common upgrade. Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement.

Planning and building rules in England
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
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
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.
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.
Do you fit smoke vent rooflights (AOVs) across Northamptonshire?
Yes. We survey and fit smoke vent rooflights (AOVs) across Northamptonshire, including Northampton, Corby, Kettering.
