I have had a terrible time with Scottish Power, it is now 6 months since I reported the problem and the matter is now with the Ombudsman. Due to a faulty meter my monthly bill has tripled and they have still not inspected or changed the meter. My contract was supposed to end two weeks ago but without my knowledge or consent they changed it to a different tariff 3 months ago and now doesn't end for 15 months, they haven't sent me any agreement.
I can't recommend Scottish Power
