A statement from OVO
26 November 2014
A known fault with gas pre-payment meters
“We’ve been working closely with Siemens and Energy UK to make sure any customers affected by this issue are refunded any money they might be owed - since they’ve been on supply with OVO - as soon as possible. We supply around 0.2% of the faulty meters and will be directly contacting and proactively refunding, each and every one of our customers as a matter of priority.
“All refunds given before the customer’s meter has been fixed will include an additional amount to cover the estimated future over charging. This will ensure that all customers affected are not out of pocket throughout the colder winter months.”
