Sliding rooflights for Colwyn Bay: the essentials
Sliding rooflights in Colwyn Bay means box rooflights whose glass lid slides back for walk-out roof access. We cover the LL29 district and the rest of Clwyd, with a survey before any price is fixed.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. In Colwyn Bay, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
From Colwyn Bay to Rhyl, Bangor, Gwynedd and Llangefni, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for 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. 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.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Sliding rooflights in Colwyn Bay: questions
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
Will I need planning permission in Colwyn Bay?
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.
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.
