EN12101-2 Compliance: Automatic Opening Vent Services in London
For building owners in London who need dependable fire safety infrastructure, The Oltec Group offers complete EN12101-2 compliant automatic opening vent services, covering design, installation and long term maintenance. Our specialist engineers configure every AOV to work seamlessly alongside existing fire alarm and detection systems, triggering rooflights, windows or vents automatically the moment smoke is detected. This keeps escape routes clearer, helps emergency services locate and control fires faster, and significantly reduces structural damage. With decades of combined experience, we give schools, offices, care homes and HMOs the confidence that their fire safety system will perform reliably.

How Automatic Opening Vent Systems Work
Fires spread quickly, which is why an automatic opening vent system must respond instantly and reliably. AOVs keep escape routes clearer, allowing faster and safer evacuation, while helping emergency services locate and control fires more effectively. They remove smoke and heat from affected areas and reduce structural property damage considerably. Oltec designs, installs and maintains AOV systems throughout London that work in unison with your fire alarm or detection system, automatically triggering rooflights, windows or vents to open the moment smoke is detected. This coordinated, fully automated response gives building occupants and emergency crews the best possible chance of a safe outcome during a fire, no matter the time of day.
AOV Testing, Servicing and Retrofit Solutions
An automatic opening vent system is only as reliable as its maintenance schedule, which is why Oltec FM recommends servicing every AOV at least twice a year. These regular six monthly checks, carried out throughout London, ensure your system will perform exactly as intended during a genuine emergency rather than failing at the critical moment. We also specialise in retrofitting AOV systems into older buildings, designing solutions that satisfy strict compliance standards without requiring major structural work. Every maintenance visit includes a full inspection of detectors, control panels and vents, followed by testing under simulated fire conditions, giving building owners complete confidence that their fire safety infrastructure remains fully compliant and dependable year round.


Types of Automatic Opening Vent Systems We Install
Every building has different smoke ventilation requirements, which is why Oltec Services installs a range of automatic opening vent types tailored to the property in question. Across London we design and fit roof vents, window AOVs, vertical vents and more, ensuring the right solution is selected for schools, care homes, offices, HMOs and other multi occupancy buildings. Choosing the correct AOV type is critical, as roof vents suit certain layouts while window or vertical vents may better serve narrower stairwells or corridors. Our specialists assess each property individually, considering building height, occupancy and existing fire strategy, before recommending an EN12101-2 compliant AOV configuration designed to remove smoke and heat as effectively as possible.
The Benefits of a Fully Compliant AOV System
When it comes to protecting people and property, few systems matter as much as a properly maintained automatic opening vent. Oltec FM provides complete design, installation and maintenance services across London, giving building owners genuine peace of mind. AOVs remove heat and smoke efficiently, reducing fire spread and minimising structural damage that would otherwise be far more costly to repair. Under Building Regulations, AOVs remain a legal requirement for many multi occupancy buildings such as schools, care facilities, offices and HMOs, so compliance simply cannot be overlooked. Ultimately, AOVs maintain a smoke free layer at lower levels, giving occupants precious extra time to escape safely, confirming why these systems genuinely help save lives every single day.
