What do smoke vent rooflights (AOVs) in Flitwick involve?
Thinking about smoke vent rooflights (AOVs) in Flitwick? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
From Flitwick to Ampthill, Dunstable and Bedford, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Electric (24 V) or pneumatic actuation
- Control panel with battery backup
- Rain and wind sensors for daily vent use
- Service and test plans
- Break-glass and smoke-detector triggers
- Servicing and testing available
- Opens automatically on alarm signal
What to check first
- 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
- Smoke ventilation is designed to the building's fire strategy — we install to that design
Regulations for smoke vent rooflights (AOVs) in Flitwick
Smoke vents are life-safety equipment: in England the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005. We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
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
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 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 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.
Can you work alongside my builder in Flitwick?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Flitwick?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
