Their customer service is completely incompetent and the complaints department non-existent. We had an issue which was a result of OVO somehow changing our meter serial number (which they initially blamed on us) on their system having been customers of theirs for a couple of years and which then meant they stopped taking payment for our gas. The correction of this went on for MONTHS. At one point we were told it was taking so long because according to their system our house didn't exist.... which is amazing because they were still managing to take payment for our electricity from our non-existent house. The only reason they even bothered to investigate this (the complaints team were completely uncontactable and not once replied to an email) was because I escalated the case the Energy Ombudsman. Credit where it's due goes to Garry M (Ombudsman Resolution Specialist) who was the only person who knew how to do his job, seemingly in the entire company. We have now left OVO and will never ever use them again. I recommend avoiding at all costs.
