I went on eon next in August and it took them until December before I started getting actual readings insted of guesswork ones. I also messaged them to ask about transfering to the lower rate, checked my original sign up and there are no penalties for changing, just don't want to leave one and then get told no room on the new one. Will get back if they say I can change. I went on to the facebook page to get in touch with them because not much seems do-able on the websiteMy contract ends in July but there's no exit fees so should be able to move without any penalty before the contract is up.
I'm going to ask to be switched to the cheaper rates as I've got to contact them again anyway as although the meter is sending the readings to E.on Drive they aren't letting billing know what they are so keep getting estimated bills.
