Smoke vent rooflights (AOVs) in Bath: what is involved?
Thinking about smoke vent rooflights (AOVs) in Bath? 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. In Bath, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
We cover all of Bath and the BA1 district, and nearby Trowbridge and Kingswood.

- Rain and wind sensors for daily vent use
- Break-glass and smoke-detector triggers
- Control panel with battery backup
- Electric (24 V) or pneumatic actuation

What to check first
- Replacing a vent with a non-equivalent product can affect the fire strategy

Rules and responsibilities in Bath
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.
