Been with OVO for 4 years always comes up as the cheapest in internet search, never had a problem I give them my readings every month bill comes back the same day or the next. Pay by direct debit and any credit on account gets interest at 3% if believe which is better than most banks. I hope they do bring in smart meters save me taking readings to send to them however having said that I will for the first 12 mths so I know the meter aint fiddling me.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
