It's rather annoying as a brit. Apparently the wholesale cost of electricty is about 7p in the UK but I get charged 25p. Something not very efficient is going on.

This is what happens when people treat the Telegraph as news rather than a source of disinformation used by wealthy vested interests to manipulate public opinion.
That I'm aware of, the "wholesale cost" does not include the local distribution networks. Those cost a fair number of pence to build and maintain.
And - I vaguely recall that the UK had world-beating taxes and surcharges on electricity - some for "green" reasons, some to spread the agony of the staggering cost overruns at new British nuclear plants, and some to help shore up the government's "general budget" financial woes.
