Energy network owners have made £3.9bn ‘excess profit’ from higher bills, says report

Citizens Advice believes Ofgem made flawed interest rate calculation for companies in Great Britain

The companies behind Great Britain's gas pipes and power lines have pocketed a windfall of nearly 4bn from household bills during the energy and cost crisis, according to a report.

The analysis, by Citizens Advice, argued that energy network owners were able to make the excess profits" over the past four years after the industry regulator misjudged their costs.
