I have an economy ten meter, but unfortunately the meter clock doesn’t change when the clocks go forward in summer time (i.e. it doesn’t go forward an hour in march). I spoke to EDF about it when I first signed up to economy ten in December last year, and they were vague about whether the clock would change (they didn’t know), and now a few months into summer I have checked and the clock didn’t change (although my hot water use etc moved to summer hours as our boiler clock changes automatically). They are refusing to refund me the amount I have overpaid because the meter clock didn’t update, and they are also claiming that it is not possible to get an economy ten that automatically changes its clock in winter and summer in London (and they refuse to change it manually either). Does anyone know if it is, and have any experience of this?
