More than three quarters of bill-paying Brits living in rented accommodation have never switched their energy suppliers, a new survey reveals.

Ofgem’s 2014 Consumer Engagement Survey also found one in five tenants are not aware they can switch to a different supplier.

The regulator is urging tenants to shop around for their energy as they could save £200 on their bills.

It suggests they ask landlords about any exit fees they may have to pay before switching suppliers and take meter readings when moving in and out of rented accommodation.

Ofgem has updated its ‘Be an Energy Shopper’ website for renters so they can use the information to make sure they are getting the best deal on their gas and electricity.

CEO Dermot Nolan said: “The number of British households renting stands at nine million and counting, yet research has shown that this group is not shopping around for their energy and missing out on savings of up to £200.”
