What do smoke vent rooflights (AOVs) in Beckenham involve?
Our smoke vent rooflights (AOVs) service in Beckenham 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
From Beckenham to Bromley, Catford and Lewisham, the same survey-first process applies: measure, specify, fix the price, then fit.

Building control and safety duties in Beckenham
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We install to the building's fire strategy and the manufacturer's certification.
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.

Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.
