Appalling company as noted by all the other reviews here - I supply regular accurate meter readings but their billing system is all over the place meaning you will suddenly find an unexpected bill for £hundreds coming through the door - this is a shock that nobody wants especially when you pay regularly so stay well away. Customer service is beyond inept and when I asked a customer service rep who his electricity provider was he paused and then said "Aeon". When I asked why he wasn't using his own employer as a provider all he could say was "Erm...inertia." So there it is from the horse's mouth - the people who work there are clearly used to these problems and don't want them for themselves so stay well away! I'll be switching provider this afternoon, inertia most definitely won't apply here...
