Smoke vent rooflights (AOVs) in Chippenham: what is involved?
Thinking about smoke vent rooflights (AOVs) in Chippenham? 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.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
We work across Wiltshire, including Chippenham, and in neighbouring towns such as Melksham and Devizes. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Chippenham
- Rain and wind sensors for daily vent use
- Control panel with battery backup
- Electric (24 V) or pneumatic actuation
- Glazed rooflight or louvred vent
- Service and test plans
- Glazed units bring daylight to stairwells
- Also usable for day-to-day ventilation
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
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Rules and responsibilities in Chippenham
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.

Smoke vent rooflights (AOVs) in Chippenham: questions
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 smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
Can you work alongside my builder in Chippenham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Chippenham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
