Smoke vent rooflights (AOVs) for Grantham: the essentials
We handle smoke vent rooflights (AOVs) across Lincolnshire, including Grantham. 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.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
Neighbouring towns include Newark-on-Trent (21 km) and Melton Mowbray (23 km). We offer a survey date when we reply to your enquiry.

What to check first

Regulations for smoke vent rooflights (AOVs) in Grantham
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
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.
