Smoke vent rooflights (AOVs) for Bishop Auckland: the essentials
Smoke vent rooflights (AOVs) in Bishop Auckland means automatic smoke ventilators at the head of stairwells and atria. We cover the DL14 district and the rest of Durham, with a survey before any price is fixed.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Jobs in Bishop Auckland are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Bishop Auckland
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Service and test plans
- Break-glass and smoke-detector triggers
- Control panel with battery backup
- Also usable for day-to-day ventilation
- Glazed units bring daylight to stairwells
What to check first
- 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 Bishop Auckland
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.

Questions about smoke vent rooflights (AOVs) in Bishop Auckland
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.
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.
