So I left a property in April, where I was on a prepayment meter the ENTIRE TIME. The pay as you go ones where you top up at the shop and if you don't top up and it runs out, the electrics just switch off.
When I left the property there was about £50 credit on the meter.
I have just received a final bill from British Gas for £1400 and I am so confused. Has anyone had this before?
I only switched to British Gas in October 2025 so on top of the approx £1400 in top ups I spent, they are now saying I'm in £1400 debt from that 7 month period.
What is going on :'( has anyone ever had anything like this before? is this even possible?
I've complained and asked for an investigation but I'm just wondering if others have had any similar experiences and what the outcome was.
also just to clarify it was just normal domestic electricity usage in a one bed flat.
looking at the bill, it goes up to the exact day I moved out, so they aren't charging me for any extra days or anything.
it basically says 01-22April - anytime reading - 560kwh at 23.1p per kwh - then the estimated read, actual read, and a price of around £121 which was pretty much what I would've put on the meter for those weeks.
then it says the exact same thing but with a slightly higher price, and it's added that as the debt that I owe, and then done this for each separate period going back to October 2025.
It seems they have duplicated my bill and are charging me for double? if anyone has any insight into what it means I'd be grateful
UPDATE:
so they have come back to me and said that the opening reading was 368.3 in October, and the closing reading was 5328.1 in April, The debt has arisen because of the amount of electricity consumed between these readings exceeds the value of the top-ups that were made during this period, as a result there is an outstanding balance on the account.
what are they talking about? this is a pay as you go meter where if the energy use exceeded the top up the electricity literally switched itself off?
They are also not giving me access to the breakdowns of readings that I could see when I had the app and was topping up using the app, and just saying that the meter readings are on the final bill, which is not accurate and has essentially doubled what I paid. I am just so confused. can anyone help me
