Swansea, along with the rest of South Wales, used to be supplied by 'South Wales Electricity Board' before privatisation. In 1990 the company went private. It was eventually sold to SSE in 2000 who continue to use the same branding for the energy sales in Wales today.


Between 1948-1973, gas in Swansea was supplied by 'Wales Gas Board; however, this stopped when it became an area of the British Gas Corporation.
