Smoke vent rooflights (AOVs) for Chester-le-Street: the essentials
For Chester-le-Street 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.
Coastal exposure along the North East means we look closely at frame finishes and seals. In Chester-le-Street, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
We work across Durham, including Chester-le-Street, and in neighbouring towns such as Washington and Houghton-le-Spring. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Control panel with battery backup
- Glazed rooflight or louvred vent
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Glazed units bring daylight to stairwells
- Also usable for day-to-day ventilation
Before you order: points to check
- Replacing a vent with a non-equivalent product can affect the fire strategy
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Building control and safety duties in Chester-le-Street
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.

Smoke vent rooflights (AOVs) in Chester-le-Street: questions
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.
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 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 work alongside my builder in Chester-le-Street?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Chester-le-Street?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
