Smoke vent rooflights (AOVs) for Islington: the essentials
We handle smoke vent rooflights (AOVs) across Greater London, including Islington. 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Typical uses for smoke vent rooflights (AOVs) include communal stairwells, corridors and atria.
From Islington to Highbury, Holloway and Camden Town, the same survey-first process applies: measure, specify, fix the price, then fit.

- Break-glass and smoke-detector triggers
- Rain and wind sensors for daily vent use

Before you order: points to check
- Smoke ventilation is designed to the building's fire strategy — we install to that design
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Regulations for smoke vent rooflights (AOVs) in Islington
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. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about smoke vent rooflights (AOVs) in Islington
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.
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.
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 do I book a survey in Islington?
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 Islington?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
