How we approach electric opening rooflights in Aberdare
For Aberdare 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.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Think of electric opening rooflights for kitchens, bathrooms and bedrooms that need fresh air as well as light.
We work across Mid Glamorgan, including Aberdare, and in neighbouring towns such as Rhondda and Merthyr Tydfil. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for electric opening rooflights in Aberdare
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
See our building regulations guide for U-values, glazing limits and self-certification.

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.
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.
Is it secure when open?
An opening rooflight is a vent, not an access hatch, so the gap is small. For security, close it when the house is empty — a rain sensor does not lock the unit.
Will I need planning permission in Aberdare?
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.
Is the survey in Aberdare free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
