Smoke vent rooflights (AOVs) in Alfreton: what is involved?
Smoke vent rooflights (AOVs) in Alfreton means automatic smoke ventilators at the head of stairwells and atria. We cover the DE55 district and the rest of Derbyshire, with a survey before any price is fixed.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. In Alfreton, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.

Common questions
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.
Do smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
