I submitted an indemnity claim after Octopus Energy withdrew an extra £220 from my account, even though I had already moved out a month earlier and paid what they labelled a “final bill.” That final bill was an inflated charge to clear a supposed debt for a one-bedroom flat, where we were being charged close to £300 per month. We found this completely unreasonable given our normal energy usage. We raised a dispute and requested a debt waiver, but Octopus took the money anyway without properly addressing our concerns. Their response was essentially, “It’s already been taken, nothing we can do,” and all follow-up attempts to get real support went nowhere. No resolution. No accountability. Just an expensive lesson. I wouldn’t use Octopus Energy again.
