Eventually I realized i was liable for the bills till the end of april due to my contract on the flat so i paid LCS. But then i realized i had not used anything during April so i contacted eon about this and they said they would revise it. I then get a statement for a ton of new reversed charges that i don't really understand and the balance changes to say i owe £19 no mention of the £92 i paid 4 days ago.
I never received a call text or email from eon about the debt i didnt know about for the last year. The balance on my account did not show -£92 so now im baffled. will eon get the £92 and will they add it to the account making it in credit by £70ish or has it vanished to some other account they hold?
Its been a nightmare
Did you ever download or receive a copy of your final statement? Did your rental contract specifically state about the energy costs in the eventuality of moving out before the end of your notice?
Others may have a view on this but here is my take if others might care to comment on the situation the OP finds themselves in.
The OP almost certainly had an obligation to pay rent on the flat until the end of the month because that was in your contract (4 weeks notice etc). However I'm not sure that the OP ever had an obligation to pay anything more to Eon Next once the final bill was raised via contacting them with your final read(s) and paid off once that final bill (due to change of tenancy) was generated. This is why I have asked if they received a final statement and downloaded it.
Surely the LL at that point in early April 2023 becomes the 'new tenant' and should have assumed responsibility for
ANY and ALL energy costs incurred immediately upon you leaving (whatever the reason) and would continue to do so until a new tenant moved in. The LL should have contacted the incumbent energy supplier (Eon Next) at that point in early April and told them 'I am the new tenant here, are my start readings'. If no energy was used the LL is responsible for these costs (standing charges only if no energy used in the meantime) until the new tenant moves in and the whole process gets repeated. Getting the money back from this debt collection agency might prove problematic given that you have now paid them monies.
It would not surprise me if the LL neglected to ever tell Eon Next that they had effectively taken over the tenancy or, if they did, they told them mistakenly IMO at the end of April 2023, instead of when you actually moved out
leaving a period of time between the early to the of end of April 2023 when Eon Next do not have a 'tenant' matched to your energy supply. Possibly the LL may have even originally told them that you are the tenant until the end of April 2023 which is why you suddenly got this bill demand for this period. Remember the new tenant would have created a new account start date and payment for the gap is what was being sought.
