Smoke vent rooflights (AOVs) for Winchester: the essentials
We handle smoke vent rooflights (AOVs) across Hampshire, including Winchester. 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Winchester, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
Neighbouring towns include Eastleigh (11 km) and Southampton (19 km). We offer a survey date when we reply to your enquiry.

Building control and safety duties in Winchester
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.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.

Yes. We survey and fit smoke vent rooflights (AOVs) in Winchester and across Hampshire. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Winchester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
