“This is a hugely significant intervention by the Secretary of State for Energy and implies that Ed Davey agrees with Which? that the structure of the biggest energy companies is partly to blame for the price hikes that millions of squeezed customers have been struggling with in recent years.
“The pressure is now on the regulators to announce next month that they are taking the first steps towards a more radical reform of the energy market, and to give consumers confidence that they are paying a fair price.”
