Smoke vent rooflights (AOVs) in Rickmansworth: what is involved?
For Rickmansworth homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Rickmansworth, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
Rickmansworth is around 6 km from Watford, and we survey and fit throughout that part of Hertfordshire, including the WD3 district.
What you can choose
- Glazed rooflight or louvred vent
- Control panel with battery backup
- Rain and wind sensors for daily vent use
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Replacement of failed or obsolete units
- Also usable for day-to-day ventilation
Things we check at survey
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
- Whoever holds the building's fire-safety duties (the responsible person, the duty holder in Scotland or the appropriate person in Northern Ireland) must keep systems maintained and tested
Rules and responsibilities in Rickmansworth
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.
See our building regulations guide for U-values, glazing limits and self-certification.

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.
