Weird that this has happened. Until recently, we were with Scottish Power & had been for a few years. Every time there was a disparity between our DD and our current usage, we would get a letter telling us that the DD would be adjusted up or down to match what we were using.
Admittedly, the last one was a bit stupid in that they wanted to double the DD at the END of winter, as we had accumulated a bit of a debit – the fact it would more than likely be evened out by the lower summer bills fell on deaf ears, although we did manage to get a reduced DD, compared to their proposal. Still ended up with a credit by the end of the summer, as I predicted & had told them we would…..
Now with OVO – it was cheaper & the customer service (so far) is very good.
Website easy to use & bills easy to understand.
