My electricity charges are significant. At one end of my shed I heat snakes whilst at the other end of the shed I freeze rats. I have just spent an hour or so comparing electricity rates and , well, its as bad as getting a mobile phone plan. So far all I have come up with the offer to contract to a discount off a variable price, which to me committing to buy electricity, exclusively from a supplier irrespective of price they chose to charge.Is this what everyone else agrees to? Do any companies offer fixed price contracts?
