Scottish Power - Avoid them - I use Octopus without problem.
I have heard so many people saying Scottish Power are demanding unreasonable amounts,or false billing, setting up direct debits without authority, faulty meters. Personally I left them several years ago and they tried to bill me for hundreds of pounds even thugh I had a pre-payment meter, but must say after I left they sent me a cheque for money they had overcharged me due to a faulty meter two years prevuously and never told me about.
