EDF Energy agrees to pay a £4.5m 'fine'

The energy supplier EDF has agreed to pay £3.5m to customers who failed to get the best deal available to them.

The payment, imposed by the regulator Ofgem, is the biggest of its kind.

It will see £50 paid into 70,000 accounts of what EDF describes as its "most vulnerable customers".

EDF denied the amount was a fine or penalty - although the total of £4.5m includes a £1 penalty.
