What do smoke vent rooflights (AOVs) in Chichester involve?
For Chichester homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Chichester, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
We work across West Sussex, including Chichester, and in neighbouring towns such as Bognor Regis and Havant. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Control panel with battery backup
- Glazed rooflight or louvred vent
- Rain and wind sensors for daily vent use
- Break-glass and smoke-detector triggers
- Electric (24 V) or pneumatic actuation
- Glazed units bring daylight to stairwells
- Servicing and testing available
Before you order: points to check
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- 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
Rules and responsibilities in Chichester
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. Fire classification of rooflight materials near boundaries is checked at specification.

Common questions
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 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.
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 you fit smoke vent rooflights (AOVs) in Chichester?
Yes. We survey and fit smoke vent rooflights (AOVs) in Chichester and across West Sussex. Send your postcode and we will offer a survey date when we reply.
