Had no issues until installing a smart meter - I've had 2 massive spikes in my energy bills coinciding EXACTLY with the dates of installation, and their response has been "your meter is fine, you owe the money" despite the fact a quick look at the account shows a doubling in my amount owed at installation times While the staff have been friendly enough - after test showed there wasn't a physical fault in the meters they've been no help is resolving this and will not reduce my debited amount owed - It seems crazy to me that they won't entertain the possibility there could be an electronic error, far easier just to overcharge the customer and tell them they owe it Contacting energy Ombudsmen to resolve and will be leaving as soon as my contract is up. If you are with Octopus and don't have a smart meter - think twice before you get one. There's a good chance it'll end up costing you.
