Octopus Energy - £4k elec bill for 11 months?

90 replies

Watchoka · 13/08/2025 20:30

Trying to help my brother.

He lives in a 2 bed flat on his own and works in an office during the day. Only has electric.

When he moved in in 2023 Shell was the electricity provider.

Octopus took over Shell in Feb 24

Since he moved in he has paid £135 per month for electricity.

In January 25 Octopus sent him a bill for £4k without explanation.

There were a series of charges made to his account in one day and then credits made on another day and then charges made again (all on one day) all adding up to approx £4k. Again no explanation.

my brother called them and they said he had only been paying estimated amounts and he had now been billed for actual usage for the last 11 months (amounting to £4k in 11 months)

I queried with Octopus whether the charges related to electricity used more than 12 months ago (back-billing) and they said no. They said they checked the account and the charges were correct. They did say that they attempted to install a new meter in May 25 but couldn’t. They didn’t say why they were installing a new one or whether the old one was faulty.

I’ve checked the usage amounts on all his bills and they just don’t add up for one person in a small apartment who is out most of the day.

The Customer Service Advisor appeared almost ecstatic when he came back to say the £4k for 11
months still owed.

I’m not sure where he goes now. The billing just doesn’t make sense and no real explanation has been given about the charges piled on in Feb 25.

Anyone had a similar experience please?

any help would be very much appreciated please

That sounds like the block bill and not the flat bill??

Why would the whole block have a bill? Do you mean communal lighting? A few light bulbs don't cost much to run.

There is a group on Facebook called "Facebook Group Energy Support & Advice UK". They have some incredibly knowledgeable industry people on there who can help guide you though the process.

That used to be a good group. The woman who ran it was skimming off the proceeds for herself, and the industry experts all left.

If you go into the Octopus app you can see all meter readings and charges. Look up the starting reading when he moved in, take a reading now and see if that matches the bill, as a first step. He must have submitted an initial meter reading when he opened his account.

Has the meter definitely not been changed? We had an insane bill from OVO once because they “forgot” the meter had changed and assumed that they could subtract the reading on the old meter from the one on the new meter. Luckily I had read both meters on the day of the change.

Unless there is a lift; they use a lot of electricity.

Oh wow, I didn't see that. I used it a few years ago when I had very similar to the OP with bulb/octopus and they were so helpful. What a shame, it was a great resource for what is a ridiculously complicated industry we all have no choice but to engage with.

Yeah, it was really helpful for a lot of people, but it went downhill quickly. The original team posted this update, I don’t know what, if anything, happened afterwards.

@katmariejust read your first post - what an ordeal! Glad you finally got justice. Sounds like a hell of a lot of work. Disappointing and concerning to hear the ombudsman didn’t ensure OVO complied

Are you sure someone else in the block has illegally connected to his meter at some point? That's a huge amount of electricity for one flat.

Honestly by the end of it I think I was powered by sheer fury and rage that they were all just so rubbish at solving the problem, and I just went for the scorched earth approach. I truly believe if my MP hadn't acted I'd still be trying to sort it out now. The ombudsman were very disappointing, I hope you have better luck with them though.

@LakieLady interesting point - I’ll check what his reading in November 24 was and compare to estimates

he has been taking readings each week since about May and usage no where near what he was previously billed for despite no changes in how using electricity.

so difficult to navigate all this

It's also possible that they opened his account with a reading lower than the actual reading, but that wouldn't account for the ongoing overcharging.
