I'm in the same boat as Ian Greenwood. I was switched to Scottish Power by OFGEM after the collapse of Extra Energy. Which I didn't ask for, I spoke to customer services as they were going to put me on a higher tariff of 75 a month I said I couldn't afford it as I'm benefits and I have serious health issues. I was told not to worry about it, but I decided to switch companies as I didn't trust Scottish Power and Often were no good. I switched to Bulb on the 28th December via one the compare sites. It wasn't until February 2019 that my supply was actually changed. Now I'm £156.00 in debt thanks to Scottish Power because they didn't switch when I requested it. I'm going seek legal advice as I think they are out of order. Not only that I have Extra Energy breathing down my neck, despite being in credit at the time they went bankrupt all of a sudden I owe them money and now I have bad credit rating.
