Just be guarded what you say on here re Octopus. I was reported to them by a member, a warning was issued to me by Octopus, when I took them to task about it they agreed they had got it wrong, they had lied to me and that I was brought to their attention by a member of this form (you can see who if you do a little digging). They also confirmed that my operation of IOG was all within T&C's and they had no issues.
Following all of this I looked around, found Tomato and moved to them, to date I have now taken over 240 people with me away from Octopus. Tomato is substantially cheaper, doesn't have the flaky software changing charging schedules and doesn't have the resident grass from here.
