The Gwynedd heating oil market
Gwynedd has one of the highest proportions of oil-heated homes in Wales, reflecting its mountainous terrain and almost complete absence of mains gas outside Bangor and a handful of coastal towns. Snowdonia National Park, the Llyn Peninsula, and the agricultural uplands of southern Gwynedd are almost entirely reliant on oil heating. The limited number of suppliers serving North West Wales and the challenging terrain in some areas can result in prices above the national average, particularly for remote Snowdonia properties.
10 regional and independent suppliers deliver here as well as 12 national ones, and prices between them can vary by several pence a litre on the same day. It is worth getting more than one price before you order.
