Smoke vent rooflights (AOVs) in Dyfed: the essentials
Across Dyfed, our smoke vent rooflights (AOVs) work covers automatic smoke ventilators at the head of stairwells and atria. Survey first, fixed price second, fitting third.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best.

Planning and building rules in Wales
Smoke vents are life-safety equipment: in Wales the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005 (as it applies in Wales). We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. 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
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 a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
How often should AOVs be tested?
Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
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 I need to be at home for the survey in Dyfed?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
