Tesla Bid to Become a UK Electricity Supplier Gets Politically 'charged'

Ah that is better. We were on the right track to bring Tesla sales to 0%. European politics are dumb I know but we have to change that and make them change the laws that make car makers to buy credits in electric car makers. That and many other laws are reallys stupid.

But having that company to supply anything is already bad.

## 1. Are all of Britain’s electricity suppliers private companies?

*Yes, all major electricity suppliers in Great Britain are privately owned.* There are no significant government-owned electricity supply companies currently operating for households or businesses. The exception was *Robin Hood Energy*, a publicly owned non-profit launched by Nottingham City Council in 2015—but it is no longer active as a general supplier.([Wikipedia][1])
