Opus Energy has agreed to pay more than £7million in refunds, redress, and goodwill payments after identifying it overcharged almost 88,000 non-domestic customers between 2003 and 2023.
The non-domestic supplier had two faults in its billing system, meaning customers were temporarily on the wrong tariff or their billing periods were incorrectly duplicated. The faults were initially identified during an audit, after which Opus Energy voluntarily reported itself to the regulator.
These two faults led to 87,825 customers being overcharged over a 20-year period. While 93% of accounts were overcharged by less than £50 in total, one customer, who has since been refunded, overpaid £102,000.
Opus Energy has since resolved the technical faults and will pay £5.5 million in refunds to affected customers. An additional £1.56 million will be paid in goodwill and redress payments.
The supplier has committed not to recover amounts from those customers who were undercharged as a result of the system faults.
It has identified all affected accounts and has processed refunds automatically for current customers. Former customers will be contacted to receive refunds where the refund due is £2.50 or greater.
Any unclaimed refunds and refunds below £2.50 will be paid to the Energy Redress Fund.
Accounts still supplied by Opus Energy have already been refunded.
