Scottish power personal assessment
Having had a lot of problems with inaccurate bills, due, I was told to a problem with the updating of their computer system, I stuck with them and for the last 18 months I have had no problems at all. Their best fixed rates can only be taken up if you accept a mandatory smart meter installation and other fixed rates can be easily beaten by other suppliers. However, their website is very good, with plenty of options to compare energy usage over months time and from previous years and the ability to change your contract to a more beneficial one, within the Scottish Power options.
