Smoke vent rooflights (AOVs) in Totton: what is involved?
Thinking about smoke vent rooflights (AOVs) in Totton? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
Totton sits about 6 km from Southampton and 9 km from Hythe, and we cover the whole SO40 postcode district and the roads in between.

Rules and responsibilities in Totton
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.
Read the planning permission guide before you commit to a design.

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.
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 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 work alongside my builder in Totton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Totton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
