How we approach smoke vent rooflights (AOVs) in Richmond
Thinking about smoke vent rooflights (AOVs) in Richmond? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
From Richmond to Twickenham, Isleworth and Kingston upon Thames, the same survey-first process applies: measure, specify, fix the price, then fit.

What to check first
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Rules and responsibilities in Richmond
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.
Read the planning permission guide before you commit to a design.

Smoke vent rooflights (AOVs) in Richmond: questions
