Conservation rooflights in Bangor, Gwynedd: what is involved?
Our conservation rooflights service in Bangor, Gwynedd covers slim, low-profile steel-look rooflights for period and listed roofs. 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. In Bangor, Gwynedd, as anywhere, conservation rooflights are the usual choice for period, listed and conservation-area roofs.
We cover all of Bangor, Gwynedd and the LL57 district, and nearby Llangefni and Caernarfon.

Do you need permission in Bangor, Gwynedd?
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.
Read the planning permission guide before you commit to a design.
