I'm still baffled by that email, which was from Octopus not Electroverse. I emailed Octopus and they said they couldn't find an account linked to my email address at all, which is worrying, and asking me for my full name, address and account number. I sent these back last night, but still no reply to that email.
However, this morning I woke up to a completely different email, also from Octopus.

Scroll to the end of the email, and I find this.

I'm pinching myself. That surely has to be too good to be true!
I don't know what's going on with the other email but it looks increasingly like a mistake.
