Octopus electricity have been a bit weird (and predatory) in not waiting for my regular meter reading date and billing me a day early for a hugely overestimated amount instead.

that, even though they took over from the previous people not that long before the pandemic (Nov.2019), they ought to have enough data to have made a more accurate / honest assessment of my electricity usage. But none of the companies I've been unfortunate enough to get passed to has ever managed that.

no smart meter for you? Ours was installed last week and we’re seeing a big benefit in rates.

not letting anyone in for something that stupid.
