How we approach electric opening rooflights in Caerphilly
We handle electric opening rooflights across Gwent, including Caerphilly. In short: hinged rooflights that open on an electric actuator for fresh air. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Typical uses for electric opening rooflights include kitchens, bathrooms and bedrooms that need fresh air as well as light.
We work across Gwent, including Caerphilly, and in neighbouring towns such as Risca and Pontypridd. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Caerphilly
- Smart-home or app control (manufacturer dependent)
- Electric actuator with wall switch or remote
- Frame colour to match your doors
- Manual winder on smaller units
- Rain and wind sensor
- Daylight and purge ventilation from one unit
- Rain sensor closes the lid automatically
What to check first
- Electrical connection should be made by a competent electrician to BS 7671
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
Do you need permission in Caerphilly?
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Questions about electric opening rooflights in Caerphilly
Can it open in a power cut?
Most electric units stay where they are during a power cut. Some manufacturers offer a manual override or battery backup — we will tell you which option the chosen model has.
What happens if it rains while it is open?
With a rain sensor fitted, the actuator closes the lid automatically when the sensor detects water. Without one, the lid stays where you left it, which is why we recommend the sensor on any unit over a kitchen or bedroom.
Can I control it from my phone?
Some ranges link to smart-home hubs or their own app. If that matters, say so at survey and we will specify a compatible model.
Can you work alongside my builder in Caerphilly?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Caerphilly?
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission.
