The BBC radio news yesterday (I was on the road for about five hours, so I heard a LOT of radio news) was full of the fact that Energy Secretary Ed Davey had told disgruntled energy customers to “shop around” after SSE put up its prices last week. Now, the commentators said, former SSE customers who had gone to British Gas had even more reason to be angry at the man who won’t do anything to curb the rapaciousness of this (might as well be) unregulated virtual monopoly. Mr Davey’s response? “Shop around”.
