Good Energy, a renewables specialist based in the South West of England, took top honours for the second consecutive year. Ecotricity came second, with Ebico and Utility Warehouse tied in third place. There were also strong showings from Co-Operative Energy, Marks & Spencer and Ovo.
British Gas, EDF, Energy, Eon, Scottish Power, SSE and Npower – which had the dubious honour of limping in last – have a 98% share of the UK market. Only Eon and SSE managed to crack the top ten – coming in joint ninth.
Which? executive director Richard Lloyd, said: "Yet again customers have told us they are fed up with the way the biggest energy companies treat them, but the complexity of energy tariffs makes it hard to shop around.”
He continued: 'The Government's energy reforms need to go much further to increase competition so that suppliers are under pressure to raise their game and keep their prices in check. We want the switching process to be quicker and for energy prices to be set out in a way that allows people to spot the cheapest deal at a glance."
