What are smoke vent rooflights (AOVs)?
Our smoke vent rooflights (AOVs) service in Berkshire covers automatic smoke ventilators at the head of stairwells and atria. We survey every job before fixing the price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors.

Planning and building rules in England
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.

- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common 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.
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.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
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.
Do you fit smoke vent rooflights (AOVs) across Berkshire?
Yes. We survey and fit smoke vent rooflights (AOVs) across Berkshire, including Reading, Slough, Bracknell.
