Gas is shipped or piped into the UK from countries such as Russia, Norway and Latin America then distributed around the UK by Transco.

Electricity is mainly generated in the UK by coal, gas or nuclear power and distributed via The National Grid.

Historically just two suppliers serviced the UK energy market. Since deregulation in the early 1990’s some 30 energy supply companies have emerged to provide the country’s energy needs. These companies buy energy on the wholesale market and sell it on to businesses throughout the UK.
