Smoke vent rooflights (AOVs) in Northallerton: what is involved?
For Northallerton homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Converted barns and mills in Yorkshire often suit bespoke or ridge rooflights that follow the original structure. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
From Northallerton to Darlington, Thornaby-on-Tees and Stockton-on-Tees, the same survey-first process applies: measure, specify, fix the price, then fit.

Before you order: points to check

- Smoke ventilation is designed to the building's fire strategy — we install to that design
Building control and safety duties in Northallerton
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. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.

Common questions
Who is responsible for maintaining smoke vents?
The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
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.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
Do I need to be at home for the survey in Northallerton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Northallerton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
