AOV in London
Automatic Opening Vent Installation & Maintenance Services
At Anchor Fire, we specialise in the installation, servicing, and maintenance of AOV (Automatic Opening Vent) systems across London. AOVs play a vital role in smoke control and fire safety, especially in residential blocks, stairwells, corridors, and commercial buildings. Our solutions ensure compliance with fire regulations, enhance building safety, and help save lives in the event of a fire.
What is AN AOV System?
An AOV (Automatic Opening Vent) system is a smoke ventilation solution designed to open automatically in the event of a fire, allowing smoke and heat to escape. This improves visibility for occupants evacuating and provides better access and conditions for emergency services.
AOVs are typically required in:
-
Apartment stairwells and communal corridors
-
Schools and hospitals
-
Office buildings
-
Underground car parks
-
High-rise residential and commercial developments
A well-designed AOV system helps keep escape routes clear and supports compliance with Approved Document B, BS 9999, and BS EN 12101-2 standards.
Legal Responsibilities
Under the Regulatory Reform (Fire Safety) Order 2005, building owners and managers are legally responsible for maintaining all life safety systems, including AOVs. Regular servicing helps ensure you're compliant and protects residents, employees, and visitors in an emergency.
