Energy supplier E.ON has agreed to pay £12 million after the firm was accused of selling incorrect tariff information to customers.
The chief executive of the firm has said he is determined to "put this right".
The following advice has been issued by the company for customers who think they may have been mis-sold a tariff:
- Who could be affected?
The energy supplier has said that customers who purchased a tariff between June 2010 and December 2013 are the most likely to be affected.
- What will they do?
E.ON will send letters to 465,000 customers outlining the steps they should take to have their account investigated by the E.ON Sales Compensation Fund.
Any customers thought to be a priority, will automatically receive a payment from the firm, which they said will be made clear in the letter. This means that these customers will not have to take action themselves.
- How will customers be compensated?
Around 333,000 vulnerable customers, including pensioners, disabled and low income families, will receive a payment of around £35. Warm Home Discount receivers will also be compensated.
- Who should you contact?
A dedicated hotline has been set up for customers with concerns. Customers can contact the E.ON Sales Compensation Fund by calling 0800 056 8497 for more information.
