I have mentioned oddities before, in online electricity and gas supplier quotes....
I use Martin Lewis's energy compare system, but all such systems seem the same. I feed in my precise previous years consumption figures and my actual consumption proves to be fairly accurate, by the end of the year. I pay a fixed direct debit, so the cost is evened out over the year, with the cost of supply on a fixed 12 month contract. So no reason really that they should need to request me to agree to an higher DD amount.
My supplier for the past 12 months was Bristol, who originally quoted me £48 per month over the 12 months fixed for E&G. Over that 12 months, Bristol kept requesting I increase my DD, most recently to £92 per month. My predicted consumption that the quote was based up, was what within a few Kw what I consumed, so why the wide cost discrepancy?
I have just over the past few weeks moved to E.On. Their quote was £52 per month, which was cheaper than continuing with Bristol. Their system is still not yet set up to accept smart or manually supplied readings from me, so they have zero idea what my consumption might be, other than the figure they quoted me on...
In the few days since the switch, their system has already suggested I increase the monthly DD from £52 to £58, now it is suggesting I increase it to £62. WHY???
