How we approach smoke vent rooflights (AOVs) in Leatherhead
We handle smoke vent rooflights (AOVs) across Surrey, including Leatherhead. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
Leatherhead sits about 6 km from Epsom and 8 km from Ewell, and we cover the whole KT22 postcode district and the roads in between.

Before you order: points to check
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- Whoever holds the building's fire-safety duties (the responsible person, the duty holder in Scotland or the appropriate person in Northern Ireland) must keep systems maintained and tested
Building control and safety duties in Leatherhead
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. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.
