Electric opening rooflights in Cardiff: what is involved?
For Cardiff homes and buildings we offer electric opening rooflights: hinged rooflights that open on an electric actuator for fresh air. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. In Cardiff, as anywhere, electric opening rooflights are the usual choice for kitchens, bathrooms and bedrooms that need fresh air as well as light.
Cardiff is the main town we list in South Glamorgan; we also cover nearby Penarth and Dinas Powys.
Specification options
- Frame colour to match your doors
- Double or triple glazing
- Manual winder on smaller units
- Insect screen
- Rain and wind sensor
- Electric opening — no poles or winding
- Daylight and purge ventilation from one unit
Before you order: points to check
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
- Needs a power supply at the opening — plan the cable route before ceilings close up
Planning and building rules for Cardiff
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
Read the planning permission guide before you commit to a design.

Common questions
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.
Is it noisy?
Actuators run for a few seconds and are about as loud as an electric blind. Once closed, an opening unit is as quiet as a fixed one.
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.
