Switch exclusive I think, used whichever switching website. Existing customers get the worst deals.
British Gas wanted to charge me more than standing charge to stay with them, and wouldn't even believe the unit rates on the plan I switched too and straight up said I must be mistaken, no plan could currently be that cheap.
So as I'm an E.ON customer, I can't get your deal? Uswitch isn't even bringing the E.ON Next tariff up. I'll call them tomorrow anyway, maybe I can persuade them to put me on your tariff.
