Plenty of companies here that are like subletters for utilities; they claim to be able to offer you a lower energy bill because they buy up electricity in bulk, but when I looked into it it turns out that in practice they're only cheaper the first year. These aren't energy companies, they're marketing / sales companies.
Anyway I went with one of the "source" power suppliers who instead offer a loyalty discount that builds up over time. I'm sure switching suppliers every year will be a bit cheaper in the long run but I choose reliability and convenience in this case. Also because the reseller companies tend to pop up and be bought up / merge constantly. Besides, it gives me some moral peace of mind that I'm paying the company producing electricity directly instead of a marketing middle man.
