Welcome to Celtic Energy

Celtic Energy is one of the leading coal mining companies in the UK. We produce over 300,000 tonnes of high quality coal per year from our sites in South Wales for domestic, industrial and specialist applications in the UK and elsewhere in Europe.

We operate surface coal mining sites in the Swansea and Neath valleys and a coal washery at Onllwyn, near Neath, where the coal is processed and despatched by road and rail to customers throughout Europe.

We plan and operate our sites to the highest health and safety and environmental standards and sites are restored for agriculture, forestry and local amenity including wetlands, tree plantations and other forms of development.
