Thanks for the info guys I'll keep you updates, this website and the people here are amazing I never expected such a rapid and comprehensive responses.

Thank you all for your responses, I will try to answer all the questions above in order 1. I don't recall receiving any letters from Npower or from SC however both said they had been sending letters Npower would have been sent in the previous tenants name. However, SC may have been overlooked by myself as I just assumed they DD was being taken out so everything was running how it should. 2. With regards to a SAR - i'm not familiar what it actually is and how I go about getting one and its benefits? 3. Billing wise I have never received a bill from them in my name and as stated above I have haven't opened the previous tenants letters to see if they had sent anything for him. I assumed it was a straight forward case they were looking for a tenant who had moved out the agent was informed and that information which was not forwarded back to NP in fact their report states nobody answered the door and they left a letter to respond within 7-days which I don't believe the agent even left for me! Look forward to your responses

I have been reading through the threads and I couldn't see anything to answer the current predicament I am in. I moved in as a new tenant on the 30th January 2015 and setup gas and electric with scottish power through a company (tenant Shop) who was given my details through the lettings agency. Scottish power setup electric and gas (or so I thought) through direct debit and then all was in place till about one month ago when we had a visit from MeterPlus who are partnered with Npower looking for a Mr Patel (previous tenant). He was informed that he no longer lives here and that was the end of it till yesterday morning when I heard some rattling outside they had returned and changed my meter to a prepayment meter and were unable to change it back unless I contacted Npower. After speaking to the reps (Npower) he said we received two requests from Scottish power and both were rejected on the grounds that debt was owed but, because the debt on the gas was apparently less they allowed that to be changed to Scottish Power but left the electric and continued to supply it until today. I explained I am a new tenant and had setup a connection with Scottish Power for electric and gas and I am not the previous tenant but they said I needed to inform them that I was a new tenant and now I need to pay the bills accrued for the last 6-MONTHS even though I never requested this from them and neither did they have authorisation from me. I have already spoken to members of their department and management team and filed a complaint due to their lack of communication and apparently not knowing I moved in as a new tenant even though their representative was informed and they accepted the application for changeover to gas but not electric. Based on this scenario my question is 1. Am I liable to pay this 6-month bill which has been accrued due to Npower assuming I am the original tenant and subsequently kept supplying me until yesterday when they changed it to a prepayment meter 2. They are requesting a meter reading from when I moved in if I am unable to provide it what is the next step to get an accurate bill (if I am liable) 3. Can I take any legal action against them for their clear failings to investigate thoroughly follow information through and for the unecessary time wasted and harrassment to me and my family. Any info would be greatly appreciated Thank you in advance
