How we approach smoke vent rooflights (AOVs) in Gainsborough
Thinking about smoke vent rooflights (AOVs) in Gainsborough? 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.
Many Midlands semis have had a single-storey rear extension added, and a larger flat rooflight or lantern is often the change that makes it feel finished. In Gainsborough, as anywhere, smoke vent rooflights (AOVs) are the usual choice for communal stairwells, corridors and atria.
From Gainsborough to Retford, Scunthorpe and Lincoln, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Glazed rooflight or louvred vent
- Service and test plans
- Break-glass and smoke-detector triggers
- Control panel with battery backup
- Electric (24 V) or pneumatic actuation
- Replacement of failed or obsolete units
- Glazed units bring daylight to stairwells
Before you order: points to check
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- Replacing a vent with a non-equivalent product can affect the fire strategy
Regulations for smoke vent rooflights (AOVs) in Gainsborough
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.

Smoke vent rooflights (AOVs) in Gainsborough: questions
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
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.
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.
Can you work alongside my builder in Gainsborough?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Gainsborough?
