The United Kingdom has one of the most competitive energy markets with over 85 active energy suppliers and at least 13 who have stopped trading. These suppliers buy energy in the wholesale market, then sell it on to their customers. Energy suppliers – the companies that send out the bills – do not necessary generate or distribute the electricity. Consumers can choose any supplier to provide them with gas and electricity at the most competitive price.
