What do smoke vent rooflights (AOVs) involve?
Across Northumberland, our smoke vent rooflights (AOVs) work covers automatic smoke ventilators at the head of stairwells and atria. Survey first, fixed price second, fitting third.
Stone villages inland in the North East can have conservation areas where low-profile rooflights are preferred. Coastal exposure along the North East means we look closely at frame finishes and seals.

Planning and building rules in England
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.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

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.
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.
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 fit smoke vent rooflights (AOVs) across Northumberland?
Yes. We survey and fit smoke vent rooflights (AOVs) across Northumberland, including Blyth, Cramlington, Ashington.
