Smoke vent rooflights (AOVs) in Plymouth: what is involved?
We handle smoke vent rooflights (AOVs) across Devon, including Plymouth. 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.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
We cover all of Plymouth and the PL1 district, and nearby Plymstock and Paignton.

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
Building control and safety duties in Plymouth
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.
What do smoke vent rooflights (AOVs) cost in Plymouth?
These are typical supply-and-fit ranges. For an address in Plymouth, scaffold, a hoist for heavy glass, or a new structural opening can move the figure, which is why we survey first.
| Option | Guide price inc VAT | Ex VAT |
|---|---|---|
| Large glazed AOV with actuators | £4,795 – £7,795 | £3,995 – £6,495 |
| Standard glazed AOV Typical | £3,595 – £4,795 | £2,995 – £3,995 |
| Replacement vent onto existing upstand | £2,995 – £3,595 | £2,495 – £2,995 |
The process, step by step
- Send the details. Postcode, rough size and a photo of the roof and room.
- Measure and check. A surveyor visits Plymouth, measures and checks structure and access.
- Fixed quote. Product, work and price in writing — nothing is ordered until you agree.
- Installation day. Usually one day into a prepared opening, longer for new openings.
