Hi Spring is a long way off and the talk is just that "talk" go to the websites that give you a saving NOW and when spring comes and there are cheaper deals change again.
It is FREE to change the only hassle is to complete the paperwork but hey if it saves money then I don`t mind a little paperwork "ANYWAY MOST OF IT IS DONE OVER THE INTERNET AND ALL YOU HAVE TO DO IS SIGN AND RETURN DOCUMENTS" i have just moved from Powergen to "Believe it or not BRITISH GAS" they have just announced an online only Green tarrif. Meter readings online , paperless bills, as you get your bill online Direct Debit payments monthly etc.
it all cuts down on cost so they can pass savings on through cheaper tariffs, not for everyone
Checkout your personal details as regards usage etc.
hope this helps
Kevin
