Smoke vent rooflights (AOVs) in Gerrards Cross: what is involved?
Smoke vent rooflights (AOVs) in Gerrards Cross means automatic smoke ventilators at the head of stairwells and atria. We cover the SL9 district and the rest of Buckinghamshire, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Jobs in Gerrards Cross 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.

- Replacing a vent with a non-equivalent product can affect the fire strategy
Building control and safety duties in Gerrards Cross
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We install to the building's fire strategy and the manufacturer's certification.
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.

Questions about smoke vent rooflights (AOVs) in Gerrards Cross
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.
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.
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 work alongside my builder in Gerrards Cross?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Gerrards Cross?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
