So, the smart meters were installed last week, after 4 days I noticed the electric charge seemed a bit high, then I noticed the amount charged by 6am averaged a higher cost per hour than during the day when I am clearly using more, that made no sense.
So, I started to think, 'oh, fuck, here we go again', and dreading having to contact OVO again.
Then I had a light bulb moment, remembering it's a touch screen monitor, I touched the amount and if by magic it changed to show kwh used, which was what I expected, then the penny dropped that the amount shown includes the daily standing charge, which is added just after midnight, and also includes the VAT.
Not that that's mentioned in the handy guide they give me, in fact it actually says the amount is for 'use', but a quick google search confirmed my conclusion.
Can't believe I was almost out smarted by a bloody meter thingy!
