What do smoke vent rooflights (AOVs) in Ellesmere Port involve?
Our smoke vent rooflights (AOVs) service in Ellesmere Port covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
Ellesmere Port sits about 10 km from Chester and 10 km from Halewood, and we cover the whole CH65 postcode district and the roads in between.

Rules and responsibilities in Ellesmere Port
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.
