Smoke vent rooflights (AOVs) for Ampthill: the essentials
Smoke vent rooflights (AOVs) in Ampthill means automatic smoke ventilators at the head of stairwells and atria. We cover the MK45 district and the rest of Bedfordshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
Ampthill sits about 3 km from Flitwick and 12 km from Bedford, and we cover the whole MK45 postcode district and the roads in between.

Building control and safety duties in Ampthill
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.

Many dual-purpose units also open for daily ventilation, closing automatically in rain.
