Smoke vent rooflights (AOVs) in Caerphilly: what is involved?
Our smoke vent rooflights (AOVs) service in Caerphilly covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
We work across Gwent, including Caerphilly, and in neighbouring towns such as Risca and Pontypridd. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Caerphilly
- Glazed rooflight or louvred vent
- Electric (24 V) or pneumatic actuation

Before you order: points to check
- 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 Caerphilly
Smoke vents are life-safety equipment: in Wales the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005 (as it applies in Wales). We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fragile-roof safety and access are planned before work starts.
