How we approach smoke vent rooflights (AOVs) in Ewell
Our smoke vent rooflights (AOVs) service in Ewell covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Ewell, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
We work across Surrey, including Ewell, and in neighbouring towns such as Epsom and Banstead. Access, parking and how the glass reaches the roof are all checked at the survey.

Things we check at survey

- Smoke ventilation is designed to the building's fire strategy — we install to that design
Rules and responsibilities in Ewell
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.

Smoke vent rooflights (AOVs) in Ewell: questions
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
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 I need to be at home for the survey in Ewell?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Ewell?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
