Electric opening rooflights in Llangefni: what is involved?
Our electric opening rooflights service in Llangefni covers hinged rooflights that open on an electric actuator for fresh air. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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 rooms that overheat in summer or steam up when cooking.
Llangefni is around 12 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL77 district.
Options we can specify in Llangefni
- Double or triple glazing
- Electric actuator with wall switch or remote

- Smart-home or app control (manufacturer dependent)
- Frame colour to match your doors
- Can be grouped with fixed units on one roof
- Same slim look as a fixed unit when closed
Things we check at survey
- Opening area may count toward purge ventilation for the room
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
Consents for electric opening rooflights in Llangefni
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. 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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about electric opening rooflights in Llangefni
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.
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.
How do I book a survey in Llangefni?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Llangefni?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
