Smoke vent rooflights (AOVs) in Hoddesdon: what is involved?
We handle smoke vent rooflights (AOVs) across Hertfordshire, including Hoddesdon. 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Jobs in Hoddesdon 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.
What you can choose
- Break-glass and smoke-detector triggers
- Control panel with battery backup
- Electric (24 V) or pneumatic actuation
- Service and test plans
- Glazed rooflight or louvred vent
- Also usable for day-to-day ventilation
- Servicing and testing available
What to check first
- Replacing a vent with a non-equivalent product can affect the fire strategy
- 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 Hoddesdon
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about smoke vent rooflights (AOVs) in Hoddesdon
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.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Do I need to be at home for the survey in Hoddesdon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Hoddesdon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
