Energy networks making big profits at expense of consumers, says watchdog

Companies that run UK's energy pipes and wires earning double-digit returns, says Ofgem

The regulator has allowed energy network companies to make bigger than expected profits at the expense of household bills, according to its own state of the market report.

Ofgem admitted the companies that run Britain's energy pipes and wires had earned double-digit returns in the last year despite its efforts to keep a lid on energy bills.
