What we fit in Llangefni
From flat-roof extensions to period slate roofs, we fit the right rooflight for the building in Llangefni — after a survey, with 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.
Jobs in Llangefni are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

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. 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.

Skylight questions: Llangefni
Do you fit skylights and rooflights in Llangefni?
Yes. We survey and fit skylights and rooflights in Llangefni and across Gwynedd. Send your postcode and we will offer a survey date when we reply.
Is the survey in Llangefni free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission 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.
Can you work alongside my builder in Llangefni?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
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.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
