"Moved to So Energy from EDF and glad I did. They were the cheapest rate I could find in Money Supermarket and beat my EDF quote by £200/year.
Switch was very smooth. Their web site is excellent and gives you the choice of having a direct debit that reflects your consumption throughout the year (ie. more in winter than in summer) or one that is consistent throughout the year - which I much prefer.
Also, gave me the ability to add my wife to the account so that she is able to make calls etc should the need arise.
And a UK support line based in London!
