How we approach smoke vent rooflights (AOVs) in Westhoughton
We handle smoke vent rooflights (AOVs) across Greater Manchester, including Westhoughton. 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 blocks of flats and commercial buildings with a smoke strategy.
Neighbouring towns include Atherton (3 km) and Hindley (4 km). We offer a survey date when we reply to your enquiry.

What to check first
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Regulations for smoke vent rooflights (AOVs) in Westhoughton
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
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 Westhoughton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Westhoughton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
