Sliding rooflights for Bangor, Gwynedd: the essentials
Our sliding rooflights service in Bangor, Gwynedd covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Sliding rooflights suit walk-out access where a hatch would feel cramped.

Planning, building control and Bangor, Gwynedd
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. 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.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.
Read the planning permission guide before you commit to a design.
