Smoke vent rooflights (AOVs) for Croydon: the essentials
Smoke vent rooflights (AOVs) in Croydon means automatic smoke ventilators at the head of stairwells and atria. We cover the CR0 district and the rest of Greater London, with a survey before any price is fixed.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
From Croydon to South Croydon, Wallington and Carshalton, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Glazed rooflight or louvred vent
- Break-glass and smoke-detector triggers

Things we check at survey
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- Replacing a vent with a non-equivalent product can affect the fire strategy
Building control and safety duties in Croydon
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.
Read the planning permission guide before you commit to a design.
