How we approach electric opening rooflights in Caernarfon
For Caernarfon 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.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Electric opening rooflights suit kitchens, bathrooms and bedrooms that need fresh air as well as light.
Neighbouring towns include Llangefni (13 km) and Bangor, Gwynedd (13 km). We offer a survey date when we reply to your enquiry.
Options we can specify in Caernarfon
- Electric actuator with wall switch or remote
- Manual winder on smaller units
- Frame colour to match your doors
- Insect screen
- Integral blind
- Same slim look as a fixed unit when closed
- Rain sensor closes the lid automatically
Things we check at survey
- Needs a power supply at the opening — plan the cable route before ceilings close up
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
Planning, building control and Caernarfon
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. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

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.
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.
Does it need an electrician?
The rooflight wiring needs a suitable supply. We can arrange it, or your own electrician can provide the spur and we connect the unit.
