That time of year again, looking to change from Sainsburys Energy and surprised to see all the TCR figures seem to be missing now. Reading online Ofgem removed the need for suppliers to show them.
Having a bit of a nightmare getting an accurate comparison as all the sites give you a projected figure based on your existing tariff switching to a temporary tariff at the end, even if you put that you are on a fixed price to say March 2019 you still have 3 months on a temporary tariff skewing the annual price and inflating the estimated savings.
Anyway, going by usage figures it looks like Avro energy comes out the cheapest and reviews seem pretty good. Usually stick to the big suppliers but can't see anything bad about them really.
