I pay monthly my average over the last 48 days since 14th Oct is about 2.5% below my direct debit.
Eg if my DD is £100, my usage over Oct & Dec was £97.50
Are you with me?
So for the next 3 months (dec, Jan & feb) I need to use no more elec than I did in Oct & Nov
This doesn't make sense to me because Dec, Jan & Feb are much colder
Am I stuffed?
