Walk-on rooflights in Llangefni: what is involved?
Walk-on rooflights in Llangefni means structural glass you can stand on, set flush into terraces and floors. We cover the LL77 district and the rest of Gwynedd, 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. Think of walk-on rooflights for terraces where the light below matters as much as the space above.
Llangefni is around 12 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL77 district.

Consents for walk-on rooflights in Llangefni
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. 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.

Common questions
Can it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
Does it need a structural engineer?
Often, yes. Where the unit sits on new or altered structure, an engineer confirms the support and the manufacturer confirms the glass.
Can you see through it?
Clear glass can be seen through from both sides. A privacy interlayer or patterned frit keeps the light while obscuring the view.
Do you fit walk-on rooflights in Llangefni?
Yes. We survey and fit walk-on rooflights in Llangefni and across Gwynedd. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Llangefni?
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.
