Smoke vent rooflights (AOVs) for Crewe: the essentials
Thinking about smoke vent rooflights (AOVs) in Crewe? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Jobs in Crewe 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
- Control panel with battery backup
- Break-glass and smoke-detector triggers
- Service and test plans
- Rain and wind sensors for daily vent use
- Glazed rooflight or louvred vent
- Servicing and testing available
- Replacement of failed or obsolete units
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
Regulations for smoke vent rooflights (AOVs) in Crewe
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
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.
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.
Do I need to be at home for the survey in Crewe?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Crewe?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
