I have an Econo 7 energy unit (Electric). When we bought our property in 2021 we opted to have both our gas and electric with the same company. Some time during the supply period I called Scottish power for a query I had. The lady who assisted me realised that I was being billed separately for both gas and electric and decide no .. it should all be added to one bill, account number changed and also never carried my existing fixed package over. By doing so, my gas package did not go over on the fixed rate package. My bill started to climb. So again .. I called to find out how I had gone from £43 a month to a staggering £93, then again to £102, then to £147 and now the last bill as of 24 March £227!! I have had an open complaint for 4 months and still nothing has been done. In the meantime we have had a smart meter installed. Now listen to this!! Its a joke. Scottish power reckons that the smart meter is just a guideline of what your bill COULD be and that it is not a true reflection of what your actual usage is!!! So is my bill then estimated?? So why install this in the first place?? I might as well as stayed on my usual meter and just provide my monthly readings online like I use to do. So I have a piece of plastic in my home that is not really of any use to me. what they are actually saying is .. we get your readings but we do not care if your bill has gone up by 300%. The next excuse the consultant has was our usage. I said what about our usage. He says it is high. Which is utter nonsense!!! Scottish power will give you a comparison of your annual usage from last year and compare it with the same time this year. Our usage LAST YEAR for GAS was 6451KWh … THIS YEAR IT IS 5250 KWh. Its much less than the previous year. Our electric is slightly higher but there is no concern there. Our issue is with our GAS bill. After chasing Scottish power to rectify this .. I have decided we will find a different energy supplier as they are a bunch of SHARKS! Scottish Power has been using my bank account as there own personal wallet but it will stop today!!! A Fixed Rate Tariff means absolutely squat to this company, laced with lies and deceit! I will be pursuing Scottish Power for a back dated refund. Complaints department only log a call .. they do not actually action or resolve customer complaints. Think twice about this company for your energy use. I am done. PS: theres only one person living at the property and it is my husband. I do contract work and not always at home. As a Tipper Driver he leaves at 06:00 in the morning and returns after 17:00 at night, our gas and most of our electric is off during the day. The gas radiators are used only in the winter months and is switched off during bedtime. AVOID, AVOID THIS COMPANY AT ALL COST.
