AOV and Smoke Ventilation Servicing and Testing

Servicing, testing and repair of automatic opening vents and smoke shafts so stairs and corridors stay clear of smoke.

In most blocks of flats, smoke ventilation is what keeps the common corridor and stair usable during a fire, for residents leaving and for firefighters coming in. If the vent does not open, or opens late, the escape route can fill with smoke in minutes.

AOV systems are usually triggered by smoke detectors on each landing and are linked to a control panel with battery backup. We test the detection, the actuators, the free area at the opening, the panel and its batteries, the firefighter override switches, and the link to the fire alarm. Where a system is failing, we repair or replace actuators and panels from most major manufacturers.

The Fire Safety (England) Regulations 2022 require Responsible Persons of high-rise residential buildings to report a fault in a key fire-fighting system, including smoke control, to the fire and rescue service if it cannot be fixed within 24 hours. Regular servicing is how you avoid that call.

The rules in each UK nation

England

In England, fire safety in non-domestic premises and the common parts of blocks of flats is governed by the Regulatory Reform (Fire Safety) Order 2005, as amended by the Fire Safety Act 2021 and the Fire Safety (England) Regulations 2022. Higher-risk residential buildings are also covered by the Building Safety Act 2022, which is overseen by the Building Safety Regulator.

Wales

In Wales, the Regulatory Reform (Fire Safety) Order 2005 applies to non-domestic premises and the common parts of residential buildings, as amended for Wales by the Fire Safety Act 2021. The Welsh Government is reforming building safety separately from England, so duties for taller residential buildings in Wales follow Welsh legislation and guidance rather than the English higher-risk building regime.

Scotland

In Scotland, fire safety in non-domestic premises is governed by the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006, and enforced by the Scottish Fire and Rescue Service. Scotland has its own building standards system and its own approach to cladding risk.

Northern Ireland

In Northern Ireland, fire safety in non-domestic premises and the common areas of houses in multiple occupation is governed by the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010, and enforced by the Northern Ireland Fire and Rescue Service.

How a job runs

  1. Tell us about the building

    Use the form or send us your fire risk assessment action plan. A few details on height, use and current systems are enough to start.

  2. Survey or desktop review

    Where we need to see the building, we visit. For some jobs, such as EWS1 scoping, we start with the documents you already hold.

  3. Fixed quote

    You get a written, fixed price with a clear scope. Nothing chargeable happens without your approval.

  4. Work and certification

    Our engineers carry out the work and leave the right certificates, photographs and logbook entries.

  5. Records and reminders

    Reports are filed by building and we remind you before the next test, inspection or review is due.

Questions we are often asked

How often should AOVs be tested?

Most manufacturers and BS EN 12101 guidance call for a weekly or monthly functional check by the building's management and a full service by a competent engineer at least once a year. Many managing agents choose six-monthly servicing to match the fire alarm.

Who has to report a broken smoke ventilation system?

In England, the Responsible Person for a high-rise residential building must report a fault to the local fire and rescue service if it is not fixed within 24 hours.
