OFGEM’s failure to effectively regulate energy suppliers has added £94 to household energy bills, the spending watchdog has said.
The energy regulator did not tighten requirements for new suppliers until 2019 or for existing suppliers until 2021, the Public Accounts Committee (PAC) said.
Some 29 energy suppliers have failed since July last year, affecting around four million households.
Customers have been left to pick up the £2.7 billion cost of the failures at an extra £94 per household, a cost that will “very likely increase”, the PAC said in a report.
The committee concluded this was due to “Ofgem’s failure to effectively regulate the energy supplier market”.
