The Office of Gas and Electricity Markets (Ofgem) has banned a Nottinghamshire energy firm from signing up new customers until it resolves ‘a number of problems with its customer service’.
Iresa, based on The Quadrant in Beeston, has had a series of complaints which has resulted in the ban.
Complaints include concerns around vulnerable customers and 40-minute waits when taking calls.
Now, Ofgem has banned the firm from taking on new customers for a second time until it can clear the backlog of complaints.
If Iresa fails to clear this backlog within the next three months, Ofgem could take further action to revoke the energy supplier’s licence.
Dermot Nolan, chief executive of Ofgem, said: “This order sends out a very clear message to suppliers that where they fail their customers on service, Ofgem will step in and take strong action.
“It’s crucial that all suppliers provide customers with good service, including acting quickly and effectively to sort things out wherever problems occur.
“Iresa now needs to act quickly and put its house in order otherwise ultimately its licence could be revoked.”
