"Flipper" an interesting price comparison website in the UK

Except that it's not a price comparison site. You sign up, you pay them £25 a year, and they monitor your energy usage and switch you automatically to the best deal. They don't take any commission from suppliers.

So, an energy broker? I'd be game - if I trusted them.
Putting a competent middleman between me and the stupid utility company is worth a few quid a year.
I like the payment structure, but it rarely survives long once "free" competition arrives.
