How we approach smoke vent rooflights (AOVs) in Colne
Our smoke vent rooflights (AOVs) service in Colne 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.
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 communal stairwells, corridors and atria.
We work across Lancashire, including Colne, and in neighbouring towns such as Nelson and Burnley. Access, parking and how the glass reaches the roof are all checked at the survey.

Things we check at survey
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- Replacing a vent with a non-equivalent product can affect the fire strategy
Building control and safety duties in Colne
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.
Read the planning permission guide before you commit to a design.

Common questions
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
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.

Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
