Many thanks for your patience. there is a ‘back billing code’ which applies if you have not received a bill for over a year, in which case you may not be liable to pay your usage going back more than a year. The code can be found here:
You will see that you have an obligation to provide a meter reading when you move into a new property.
On the other hand, suppliers should try to ensure that they:
· try to read meters every year;
· use actual readings, to improve the accuracy of future bills
As to back billing it states:
“If your supplier is at fault and has not sent you an accurate bill that they should have sent you, they will not ask you to pay any extra for energy you used (and which you did not receive an accurate bill for) more than one year before they issued the bill.”
The issue is that this code will not necessarily be enforceable in court so to challenge them over this you need to go through their complaints department or raise a case with the Energy Ombudsman. Of course you may raise this as a defence with the court claim as well and the court will decide whether to take into account the code and how enforceable it would be in court.
I hope this has answered your query. I would be grateful if you could please take a second to leave a positive rating (3, 4 or 5 stars) as that is an important part of our process and recognises the time I have spent assisting you. If you need me to clarify anything before you go - please get back to me on here and I will assist further as best as I can. Thank you
