What do smoke vent rooflights (AOVs) in Nailsea involve?
Our smoke vent rooflights (AOVs) service in Nailsea 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.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
From Nailsea to Portishead, Clevedon and Clifton, the same survey-first process applies: measure, specify, fix the price, then fit.

Rules and responsibilities in Nailsea
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. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about smoke vent rooflights (AOVs) in Nailsea
Who is responsible for maintaining smoke vents?

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
