What do smoke vent rooflights (AOVs) in Hazel Grove involve?
For Hazel Grove homes and buildings we offer smoke vent rooflights (AOVs): automatic smoke ventilators at the head of stairwells and atria. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Jobs in Hazel Grove are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Choices for your Hazel Grove project

- Electric (24 V) or pneumatic actuation

Things we check at survey
- Replacing a vent with a non-equivalent product can affect the fire strategy
- The product should be certified to BS EN 12101-2 as a natural smoke and heat exhaust ventilator
Building control and safety duties in Hazel Grove
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.

Common questions
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.
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.
Do you fit smoke vent rooflights (AOVs) in Hazel Grove?
Yes. We survey and fit smoke vent rooflights (AOVs) in Hazel Grove and across Greater Manchester. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Hazel Grove?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
