Smoke vent rooflights (AOVs) for Plymstock: the essentials
Our smoke vent rooflights (AOVs) service in Plymstock covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
We work across Devon, including Plymstock, and in neighbouring towns such as Plymouth and Paignton. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Control panel with battery backup
- Rain and wind sensors for daily vent use
- Service and test plans

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 Plymstock
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.
Read the planning permission guide before you commit to a design.

Common questions
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 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 Plymstock?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Plymstock?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
