Smoke vent rooflights (AOVs) in Chesterfield: what is involved?
We handle smoke vent rooflights (AOVs) across Derbyshire, including Chesterfield. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Chesterfield is around 37 km from Derby, and we survey and fit throughout that part of Derbyshire, including the S40 district.

Rules and responsibilities in Chesterfield
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Questions about smoke vent rooflights (AOVs) in Chesterfield
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.
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 Chesterfield?
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 Chesterfield?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
