Smoke vent rooflights (AOVs) in Lancaster: what is involved?
We handle smoke vent rooflights (AOVs) across Lancashire, including Lancaster. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
Lancaster is around 32 km from Preston, and we survey and fit throughout that part of Lancashire, including the LA1 district.
Options we can specify in Lancaster
- Electric (24 V) or pneumatic actuation
- Control panel with battery backup
- Service and test plans
- Glazed rooflight or louvred vent
- Rain and wind sensors for daily vent use
- Glazed units bring daylight to stairwells
- Also usable for day-to-day ventilation
What to check first
- Replacing a vent with a non-equivalent product can affect the fire strategy
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Regulations for smoke vent rooflights (AOVs) in Lancaster
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We install to the building's fire strategy and the manufacturer's certification.
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
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.
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.
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.
Can you work alongside my builder in Lancaster?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit smoke vent rooflights (AOVs) in Lancaster?
Yes. We survey and fit smoke vent rooflights (AOVs) in Lancaster and across Lancashire. Send your postcode and we will offer a survey date when we reply.
