As a matter of fact I have a good friend who works for a British energy provider, and he’s been keeping me up to date on how providers in the UK are struggling. In fact, many of them have gone under and more will very soon.
His company is struggling to take up the slack. Some of the provider crisis is artificial, because of how energy regulations deal with price fixing. The system is, amazingly, not built to take rapid supply price increases into account. Prices go up, providers go bankrupt.
That’s bad enough, but what nobody’s talking about is why supply prices are going up. Brexit isn’t the only reason, but it’s a big reason, and you won’t see that being reported anywhere, not even the Guardian.
