Smoke vent rooflights (AOVs) in Wigan: what is involved?
For Wigan homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. In Wigan, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
Jobs in Wigan are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Service and test plans
- Rain and wind sensors for daily vent use
- Control panel with battery backup
- Opens automatically on alarm signal
- Servicing and testing available
Things we check at survey
- 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
- Replacing a vent with a non-equivalent product can affect the fire strategy
Rules and responsibilities in Wigan
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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 a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
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) in Wigan?
Yes. We survey and fit smoke vent rooflights (AOVs) in Wigan and across Greater Manchester. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Wigan?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
