(Reposting here and I just wrongly posted this in Chat).
I just had an energy bill cancelled yesterday (after months of them chasing me), so I thought I'd share what happened:
When I moved into a new property last year I picked up the card that the previous energy supplier had posted through the door, so I got in touch and gave them gas/electricity readings. I am a loyal customer of a specific energy provider so I knew I wanted to switch which I went on to do. I then was billed by the previous provider which came to around £8, so I paid it immediately and then switched to the new provider. Several weeks later, the previous energy provider sent me a bill for 3 days' use which came to £100+! The property I am in does not have a smart meter so it was their estimated reading.
Obviously, I was furious. Since that time, the previous energy provider was chasing for payment and I wrote to them about 6 weeks ago to say that I didn't agree with their estimated £100+ bill for those 3 days. It was very hot when I moved here (there was a heat wave at the time), so the heating wasn't on, and I wasn't in much as I was eating out a lot at the time. The dryer also wasn't working and I didn't have a TV at the time so there was nothing that pointed to high energy use.
I contested the bill, raised a complaint and then the previous provider wrote back a few weeks later to say that they looked into the complaint and still believed that their final bill for me was correct and so they weren't going to budge on the £100+.
This escalated to the previous provider calling me every day (once in the morning and once in the evening!) chasing me for months. I didn't answer the phone for a while. Last week, I got very fed up and I wrote to them to explain that I don't believe their bill was correct, wasn't reflective of my use over those 3 days, and informed them that I would be making a complaint about them to the Energy Ombudsman.
This is the response I received from one of their managers yesterday:
'Although we do feel the final statement we sent to you was correct I am happy to resolve your complaint by crediting you with £xxx.xx which will close the account and take you to a £0 balance. If you would still like to take this to the ombudsman and are unhappy with my resolution please do let me know.'
So if you feel that your bill is incorrect/unfair, it is worth a try if you didn't know about this or haven't done so already.
