I think they have to come out and check the meters periodically anyway - although I have to say since we have been switching we have never had anyone out in 6 yearsto do this, so I can't say for sure. We did have a bloke turn up from Swalec to check the meter, but I told him we're not with Swalec and he said yes we were according to his records and that this was a meter check. I assured him we were not and to check his records again - and then he realised there was a muddle up on the meter numbers

(why am I not surprised). So he apologised and legged it. Never seen anyone else to check the meter to date though, so I'm wondering whose responsibility it is for checking the calibration - perhaps it's all gone to pot now the energy market has opened up with all these new suppliers.
We've recently left 2 new suppliers - Iresa who went under, then the ombudsman agreed an interim arrangement with Octupus, who we left as they were far too expensive, so went to Outfox The Market, until they pi**ed off all their customers by suddenly doubling their customer's direct debits for the winter, regardless of actual consumption!
So thousands took to complaining and venting their anger on Trustpilot and they have now issued a grovelling apology as customers left in their thousands in protest. I bet the bright spark who dreamt that one up is now at the Job Centre.
So we are now on a fixed 2 year tariff with no increases - with Green Energy network - one recommended by that Moneysupermarket site (other sites are available

) which we found after doing the latest comparison site searches. Just as well too, as all the energy wholesale prices have just soared again.
