Smoke vent rooflights (AOVs) for Farnham: the essentials
Smoke vent rooflights (AOVs) in Farnham means automatic smoke ventilators at the head of stairwells and atria. We cover the GU9 district and the rest of Surrey, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Farnham sits about 5 km from Aldershot and 8 km from Fleet, and we cover the whole GU9 postcode district and the roads in between.

- Replacing a vent with a non-equivalent product can affect the fire strategy
Rules and responsibilities in Farnham
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.

Common questions
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.
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 do I book a survey in Farnham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Farnham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
