Maybe these people would rather be left the fuck alone!
Probably they would. But DECC and Ofgen are determined to see the energy market as a huge "market failure" requiring their intervention. As one of the most heavily regulated markets anywhere in the world, the UK energy market is a Frankenstein creation of successive public sector bureaucrats, and the problems they are trying to solve are generally down to their previous interference and incompetence. Nobody knows what's good for them quite as well as a civil servant paid to think and spend on their behalf.
Lets say you want to set up an energy supply company, just buying wholesale and selling, not doing networks, not generating. Ofgem's standard electricity supply licence conditions are a 473 page document, and gas supply is nice and concise at 363 pages.
And that's before the separate 229 pages of smart meter licence conditions, and before a bazillion pages of network codes and related documents.
The CMA have spent a year navel-gazing (at your expense) and the best they can come up with is a recommendation to spam the British population to death. Have you noticed the irony, the government put charities on notice over their spamming and mail-harassment of potential donors, but in the case of energy customers the fuckwits see just such an outcome as a measure of their success?
