Skylights and rooflights in Caernarfon
From flat-roof extensions to period slate roofs, we fit the right rooflight for the building in Caernarfon — after a survey, with a fixed written price.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass.
We work across Gwynedd, including Caernarfon, and in neighbouring towns such as Llangefni and Bangor, Gwynedd. Access, parking and how the glass reaches the roof are all checked at the survey.

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

Skylight questions: Caernarfon
Do you fit skylights and rooflights in Caernarfon?
Yes. We survey and fit skylights and rooflights in Caernarfon and across Gwynedd. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Caernarfon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in 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.
Do I need to be at home for the survey in Caernarfon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can I cancel?
Made-to-measure products are excluded from the statutory 14-day cancellation right, but you can cancel without charge until we place the order with the manufacturer. Our terms explain the rest.
Will a rooflight make my room too hot?
It can on a south-facing roof with clear glass. Solar-control glass, an opening unit and a blind keep the room comfortable.
