Smoke vent rooflights (AOVs) in Widnes: what is involved?
Smoke vent rooflights (AOVs) in Widnes means automatic smoke ventilators at the head of stairwells and atria. We cover the WA8 district and the rest of Cheshire, with a survey before any price is fixed.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
We work across Cheshire, including Widnes, and in neighbouring towns such as Runcorn and Halewood. Access, parking and how the glass reaches the roof are all checked at the survey.

Building control and safety duties in Widnes
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.

Questions about smoke vent rooflights (AOVs) in Widnes
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Do you design the smoke strategy?
No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
Can you replace an old smoke vent?
Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.
