Why would anyone change energy provider when what you buy is the same?
The only reason is the tariff and billing. It seems to be that most of the different tariffs expect you to gamble in some way - commit to X years at a fixed price and hope prices don't fall, for example. Some work on budgets that are DD regular amounts and can get out of step with reality. All I want is to pay for what I use at a fair price, no messing about.
Well British Gas keep messing about. They have chased (and probably filed bad credit reports) bills that they had never sent, and done that several times.
Their latest - a bill on my door step today, 17th September 2014, that clearly states "Your payment is due by 27th August".
WTF? Unless they mean 27th August 2015, I am seriously unimpressed. What is the point of sending a bill over a month after the bill date (13th Aug) that is already overdue when it arrives.
This sort of crap really does make me think about switching supplier.
