How we approach smoke vent rooflights (AOVs) in Middlesbrough
We handle smoke vent rooflights (AOVs) across North Yorkshire, including Middlesbrough. 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.
Conservation areas and stone villages across Yorkshire often call for conservation rooflights in slate or stone-slate roofs. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
Middlesbrough is around 69 km from York, and we survey and fit throughout that part of North Yorkshire, including the TS1 district.

What to check first

- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Building control and safety duties in Middlesbrough
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
Do I need to be at home for the survey in Middlesbrough?
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 Middlesbrough?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
