Planning and building rules in Northern Ireland
Smoke vents are life-safety equipment: in Northern Ireland the appropriate person must keep them maintained under the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010. We install to the building's fire strategy and the manufacturer's certification.
For non-domestic buildings in Northern Ireland, Technical Booklet F2 covers energy performance; we supply the manufacturer's data for building control. Fire classification of rooflight materials near boundaries is checked at specification.

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.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
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.
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 I need to be at home for the survey in County Tyrone?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
