Twelve million households could be hit by a loyalty penalty in 2021, overpaying by an average of £200 to their energy supplier, new research has revealed.
Those still on expensive standard variable tariffs will be paying a couple of hundred pounds more than those who have signed up to cheaper fixed-term rates, according to energy provider, Bulb.
Consumers affected by the loyalty penalty, which means loyal customers get charged more than new ones, pay an average of 23 per cent more compared to new customers joining on the cheapest rates.
This is a long standing practice but the Government has now promised to take action in its Energy White Paper.
