How we approach smoke vent rooflights (AOVs) in Bedford
We handle smoke vent rooflights (AOVs) across Bedfordshire, including Bedford. 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
We work across Bedfordshire, including Bedford, and in neighbouring towns such as Sandy and Ampthill. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Electric (24 V) or pneumatic actuation
- Break-glass and smoke-detector triggers
- Control panel with battery backup
- Glazed rooflight or louvred vent
- Service and test plans
- Glazed units bring daylight to stairwells
- Replacement of failed or obsolete units
Before you order: points to check
- 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 Bedford
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.

Smoke vent rooflights (AOVs) in Bedford: questions
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.
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.
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.
How do I book a survey in Bedford?
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 Bedford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
