I’m a landlord that has worked with all the big and most of the small energy suppliers in the U.K. I can easily say, Scottish Power is by far the WORST energy supplier in the U.K. I think their license to operate should be cancelled. I had so many issues, I don’t think this comment box will be big enough to explain. Whatever you do avoid them. I’m writing this review while waiting on the line for more than 1 hour to challenge an additional bill for a house that was empty at the entire period Scottish Power was the supplier and all the main Power was switched off and they charged me over £500+ for nothing! They are so fraudulent, I actually can not believe they are allowed to do business in this country. This call I’m still on hold of for is for the final bill they created from thin air and constantly chase me for payment (I’ve changed suppliers) and when you ring them back, you wait for 1 hour + with no answer. Absolutely & utterly the worst energy company in the U.K.!!
