Smoke vent rooflights (AOVs) for York: the essentials
We handle smoke vent rooflights (AOVs) across North Yorkshire, including York. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Conservation areas and stone villages across Yorkshire often call for conservation rooflights in slate or stone-slate roofs. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
York is the main town we list in North Yorkshire; we also cover nearby Selby and Harrogate.

Rules and responsibilities in York
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.
Read the planning permission guide before you commit to a design.
