My energy provider (Octopus), persistently tell us that our direct debit is too low. They have a model on their website, which predicts what your account balance will be going forward if you pay different direct debits amount a month. They suggested we needed to pay £100 more a month than we are now, and that if we stuck to our preferred direct debit amount (we can decide it, up to a point), we'd be £1.5k in debit by this time, even taking into account the £67 a month from the government. So here we are, at the end of February, and our balance is -£150, and that will be covered when we pay the direct debit in a few days. Am I right in thinking that their "predictions" are a pile of doo doo? The weather will be getting warmer, we've had the worst of the winter, and we won't be using half as much gas over the next 6 months, and we'll be building up a lot of credit for next winter. I just don't believe that we need to be building up the sort of credit that Octopus think we do. I'd completely agree that we weren't paying enough IF at the end of winter we had a massive debt, but we don't, so I just do not get their reasoning. What's a normal sort of balance to have on the account at the end of February?
