Just got a very apologetic email from Bulb saying they're real sorry but wholesale energy prices have risen and they're going to have to raise my energy bill another £122.49p a year.

Turns out, yes, prices have risen... by a whopping 0.2p per KWh.
And for that, they thought they'd charge 10x more to the consumer (a rise of 2p per KWh)
So they're paying 5.6p and charging 17.7p, a 300% markup (admittedly I'm on one of the more expensive tariffs but I don't have much choice due to being on a prepay meter)
Sick of getting ripped off 😞
