What do smoke vent rooflights (AOVs) involve?
Our smoke vent rooflights (AOVs) service in County Fermanagh covers automatic smoke ventilators at the head of stairwells and atria. We survey every job before fixing the price.
Conservation areas and listed buildings in Northern Ireland are excluded from householder permitted development, so we check before quoting. Northern Ireland has a mix of terraces, bungalows and rural farmhouses, and rooflights are a common upgrade when extending.

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.

- 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.
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 I need to be at home for the survey in County Fermanagh?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
