What does skylight installation in Colwyn Bay involve?
For Colwyn Bay homes and buildings we offer skylight installation: survey, supply and fit — new openings, extensions and fit-only work. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Think of skylight installation for new extensions, new openings and fit-only jobs.
Colwyn Bay sits about 16 km from Rhyl and 28 km from Bangor, Gwynedd, and we cover the whole LL29 postcode district and the roads in between.

Before you order: points to check

Consents for skylight installation in Colwyn Bay
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.
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 skylight installation in Colwyn Bay
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
How long does installation take?
Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Can you work alongside my builder in Colwyn Bay?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Colwyn Bay?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
