back to article Gas bill climbed £13,000 after correct online reading given

Reg Reader and Stockport dweller Rob was shocked to find that trying to save his mother a few pounds on her gas bill ended up pushing the tab up £13,088.43, rather than down the 20 quid he was expecting. It was the unlikely result of entering a meter reading on Southern Electric's website. Utility companies have a patchy …

    Not just software stupidity.

    last year an accuread man took a meter reading from my meter (i had to fill in a card because I was apparently "out" when he came round, despite me hearing the card come through and my car being on the drive, and him having to walk past the gas meter). I filled the card with the correct readings, and the meter reader then duly entered completely different ones on his little device when he could be bothered to actually turn up and read my little card. I got a £3000 bill, and it then took several calls to e.on before one of them looked at the numbers and suggested that it was a little "unusual" to use that much energy in a month. I noted they were very keen to get a correct reading this time around though (entirely coincidentally my bills will be going up by 15% or so, so they will be sure that any overestimate was nullified before the rise).

      Retard brigade down at British Gas high command decided to merge my previously separate electricity and gas accounts. Their website now requires I enter *both* meter readings or it fails with a validation error.

      My electricity meter is in the house, my gas meter is is in an inaccessible locked box outside.

      That would be the same British Gas who managed to switch MY supply after my neighbour gave them the wrong flat number... cue shock billing with my existing provider who based my final bill on an estimate.

      1. Ed


        And the same British Gas that managed to take over £400 in advanced direct debit in 3 months and saying I had to wait 8 months before they'd adjust how much money they were taking each month. That could easily have meant that they had over £1000 of my money. Hardly worth it for saving the 5% or whatever it was for using Direct Debit.

      Or maybe it was because I didn't use one of their many domains that they use (,,,, ...). I can't remember now which of these I should keep using lest I'm deemed not to be an Internet (note the capital) user.

    It's not just Southern Electric

    It's not only Southern Electric whose web-based meter reading system can't cope with actual readings that are lower than the company's estimated reading.

    A couple of months ago, I tried to enter my own gas meter reading into Scottish Power's web site. It was 20 units lower than the estimated reading on the bill I'd just received, and Scottish Power were proposing to raise my monthly payment by a hefty amount based on their estimate, so I was keen that they should get the true reading.

    Their web site refused to accept my reading. It told me twice that I'd made a mistake, and on the third attempt, it told me to expect a call from their customer service department.

    After waiting for several days, I called Scottish Power myself, and a friendly customer service person was happy to enter the correct reading. I suppose I should be glad that they didn't try to bill me for 10,000 non-existent units of gas!

    1. Robert Harrison

      I had a similar story with Scottish Power. I had the usual quartely 'your meter readings are due' email reminder. Logged in to Scottish Power and noticed that the previous meter readings were unusually low (in the 00's) instead of around the 7000 mark. Turns out the previous reading was supplied by someone who turned up to read the meter.

      I thought nothing of it and entered the correct readings. Scottish Power's website then proceeded to tell me that I owed them £9000. Of course you are then locked out from supplying any different readings for that day. Rang customer services, on hold for 30 minutes! (Argh) and was told politely by the operator that she was also locked out of editing my account. However, to her credit she at least rang me back 15 minutes later to say she'd had a word with her supervisor and managed to correct everything. Although she did say check the follow up bill and call them back if there were any problems. I notice this becoming more common practice these days, get the customer to do the work that the service/utility provider should be doing themselves and not allowing to happen in the first place.

    Had this happen to me

    with Scottish Gas.

    Hardly a big problem. Gave them a call and was assure I wouldn't be billed that much. And I wasn't.

      Disconnect the gas pipe just as it comes out of the meter and let it free-flow. In reality it turns out the meter stops working after the third explosion on day 2.

        It takes 10p-20p worth of gas to blow up your average sized house - hardly going to make the wheels of the meter rotate at a blistering speed.

      One million cubic feet

      One unit on an older gas meter is 100 cubic feet according to . 10,000 units would be one million cubic feet.

      The average home floor plan is reportedly 91 square meters, which is about 980 square feet. Allow ten feet of height (which is more than adequate!) and you get something like 10,000 cubic feet in an average property. So a wrap-around on the meter would completely fill 100 average properties.

    Plenty of time to pay

    Well Southern Electrics Feed-In-Tariff meter reading page was down altogether when I tried it 6 days ago, had to email the reading in.

    They give you just a 5 day window to submit the reading and then say "We aim to make your payment within 65 working days after receiving your readings" so 13 weeks.

    If that's their terms when they owe you money I guess it only fair we apply the same terms when we owe them.

    1. Andus McCoatover

      65 "workin' daze" . That's 3 months in 'real numbers'

    Lots of gas?

    So if you have a meter reading of say 1000, and then over the course of a billing period manage to use 10001 units, your meter ought to read 1001, would you only be charged for 1 unit of gas?

    Time to put the gas on ultra!

    I suppose to make it less suspicious you should use 10400 units or something similar.

    The Joys Of User Friendly Automation

    Couple of big phat phails there. Communications phail. Behind-your-back game-changing phail. Customer expectation phail. And so on, and so phorth. At least they're promising (after the victim done and gone public) to not actually demand the customer pony up for their greedy stupid stuff, but of course with a company full of phailure like that, everyone else'll be thinking "we'll believe it when we see it".

    As a prudency measure, just how likely the gas meter has run up to 9999, back to 0, and up to slightly under the estimate, eh? It's unlikely even if it's below the previous estimate (if that was an estimate), so it's hardly reasonable to set your own estimates in stone. Inviting the customer to get stung with an outrageous bill in the name of customer friendlyness is just that more icing on the cake.

    The worst thing is, of course, that it's entirely avoidable. A couple seconds thought, playing "what if" scenarios, and if that's too hard (and what're you still doing playing developer, or worse, project manager for this customer facing project, eh?), there are rich online resources with lots of discussion. A good one is the old RISKS list (or digest), and its archives. I'd read it more often if it wasn't so depressing. Pretty sure these peeps have earned their mention there, too.

    If Southern really expect their customers to wrap their meters within the space of 2 weeks then they must be losing an awful lot of money through quarterly billing.

  10. Still Water

    Just, huh? If that's a feature, then the person who designed it needs to have a severe re-think. Sure coping with the 99999 roll-over might have a little bit of logic, but when you're in the 13000s, it's rather unlikely...

    Umm - my meter (replaced with a brand new one last year) actually has 5 digits before the decimal point. So this makes no sense? Yes, loop at 100,000 - but not at 10,000. Methinks there could be more to this than the explanation given?

    1. Ian Ferguson

      Mine only has four digits, and that's fairly common, especially with older meters. Your newer one probably has more digits precisely because of this issue.

      1. ChrisC Silver badge

        Metric vs Imperial

        Metric meters increment 2.83x faster than imperial ones (m^3 vs 100's of ft^3), so adding an extra digit to metric meters also means they'll not wrap-around any sooner than an imperial one given the same volume of gas flow.

      2. Ken Hagan Gold badge

        "Your newer one probably has more digits precisely because of this issue."

        Possibly, but since the 4 digit wrap-around corresponds to a £13,000 bill, I'm inclined to think that 4 digits is already sufficient to avoid ambiguity.

        Perhaps the modern trend for not bothering to read meters means that the interval between *reliable* readings is now an order of magnitude longer than it used to be.

  13. JaitcH

    Perhaps they were factoring in anticipated ...

    potential fuel rate increases.

    The utility hikes in Britain are highway robbery.

    Other suppliers look up historical consumption patterns and if there is a variance outside certain limits the account is flagged for human intervention.

      Scottish Power don't

      With last years cold spell my daily electrical useage spiked at 65Kwh - about 2.5 times normal. Got to love the rotten storage heaters my landlord has fitted :(

      At the same time my fixed price deal came to an end and it was a month before I clocked on.

      The didn't call me, but I did get a nice message when I entered my meter readings that my monthly direct debit was going from £40 per month to £106, some haggling got it down to £90, but I'm seriously considering moving somewhere warmer - ideally with no snakes though

  14. Eddie Edwards

    Funny, EON wrote to me when their meter reader made a balls up (instead of reading 05454 or whatever, he'd read 15454). They didn't state the amount, they just said "mind checking your meter reading and giving us a call, you're due a large bill and we want to make sure it's right". Much better than the heart attack of receiving a 5-figure bill.

    I ended up figuring out how much gas they reckoned I'd used, and it was half a gasometer's worth. You'd have thought they might have noticed that much gas going missing ...

    Rob's mom was obviously running an iron smelting foundary in her garden shed, and not declaring the profits to HMRC. Stands to reason...Evidence abundantly clear. (Well, clear enough for British plods).

    1. Velv

      Iron smelting foundaries tend to generate a lot of steam as you cool the steel, which makes them difficult to hide. You can stick up a Leyllandi hedge but people tend to notice huge plooms of white vapour, and consequently HMRC know where 80% of the foundaries are.

      More likely to be some furuistic advanced fractional cracking process splitting the methane into carbon for the production of man-made diamionds and the hydrogen for sale to all the Honda Clarity owners in Stockport (although I'm guessing a quick check of the DVLA records would show up an illegal hydrogen production facility).

    Not only the biggest logic fail I've ever witnessed, given they have prior history on the user's account in order that they could do the estimate, but they even felt the need to state that they wouldn't actually be charging £13k - no shit, that'd be illegal. Utter muppets.

    The most obvious test is to assume lower readings than estimated are being entered. If they can't get that right then there is no hope for them.

    And to try to excuse it by some arbitrary time limit on being able to correct the bill, even though it is yet to be paid, just beggars belief.

    Why is it that it seems it's the clowns that make all the decisions these days?

  20. Shaun 1

    I used to work for an electric company

    And I dealt specifically with these problems.

    When a meter read comes in that is either lower or signicicantly higher than the previous read (usually an estimate) the system will accept it but recognise that it is outside the normal consumption threshold for that type of account and would flag it to be manually checked/corrected (usually by removing the estimated read), which all happens before the bill goes out.

    However, as the online page gives an estimated billing amount instantly, the manual adjustments don't get done.

    That's Y2K to you...

    People never learn the wonders of carry-one digit, be it 2k or 10k.

    Around here the *ELECTRIC* companies usually asked you to draw (YES, *draw*) on the bill where the needles were pointing at, when it was done on paper (only needed when you believed your bill was a tad over the board). When they changed to digital, they asked the number that showed on the *previous* bill, along with the current reading. Mind you, this form was filled by the technician, in front of you.

    Yes, you should have kept a copy of the previous bill, what, didn't you? Shame on you, 'cause we are using our estimate then.

    Then again, the meters wrap around at 1 or 10 million kW/h, and it becomes pretty obvious when the jump happened, being the same meter model for large companies or a home. And there is a visible spinning disk, that goes faster with higher consumption. It is barely noticeable on a home, but it spins like a fan when reading for large companies.

    They just end up knowing when the meter jumped, because the amount that would show up as consumed was more than the entire building or the transformer up on the street corner could ever deliver in two (or ten) years. Many meters still show a preceding zero or two on the last digits...

    I bet they spent *less* money building a larger universal meter that held longer before resetting. For gas, you may change the valve, but you could use the same "hodometer" measuring up to 10.000 or 100.000 m3 before leaping.

    That just shows lack of human supervision in the end.

  26. Your Error Message Here Silver badge

    How quaint

    Here in Massachusetts, I think they switched the gas, water and electric meters to remote RF read systems, so the various "readers" just drive down the street remotely "reading" everyone's meters, oh, about 20 years ago. They all did so because it's not just more accurate, it's cheaper because one reader-person can read roughly ten times as many meters in a day.

    Maybe Southern Electric should think about joining the 20th Century. (Joining the 21st might be asking too much.)

      Market differs in the UK

      That is to say there IS a market. In MA I expect you have access to gas via exactly one supplier for an area. In the UK you can have access to many. The meters are not changed, just the bills come from a different "retailer". So basically in the MA monopoly system only one company needs to decide to upgrade meters, in the UK free market system, either all companies agree or the govt forces the upgrade by regulation (this is happening).

    Same thing

    Hah, exactly the same thing happened to be last year. I hadn't put in an actual reading all year, so they were going on my estimates, and when I did put in a reading it was not only less than their estimated reading for that quarter, but less than the reading for the quarter before (owing to a new boiler I guess. And me wearing jumpers in winter). I was expecting to owe about £20; the actual amount I owed was -£12; my bill was something in the region of 10 grand. After looking at it for a few seconds and realising it couldn't possibly be correct, I saw the funny side.

I eventually allowed one of their blokes to come in and see that there was no gas supply, no meter, no appliances or central heating; his comment - "Well, you must have had it removed."

    Yeah, I get an email through the webs (from Scottish Power) saying it's time for me to give my electricity meter readings...

    So as per my built-in priority system; this was shunted off to long term storage and ignored.

    2. Gas man read the wrong number and gas company billing system assumed I had wrapped the gas meter.

    In fact, Energy companies have gotten massively lazy, relying far too much on the customer entering their readings, instead of sending a meter reader around to get the correct readings.

    So, we pay a premium amount of cash for a sub-standard service.

    I got a quarterly estimated reading on my (late) father's empty house. It was bigger than any bill for any entire year even when he was living there and actually using gas. Any amount of telling them that their estimated reading would have been wrong even if my father was still living there - let alone for an empty property - was met by the entirly predicable response that that was what the computer had calculated, so there was nothing they coul do about it.

    What was a bit more wierd was that if I did not pay the stupidly high ESTIMATED bill, they would take me to court. The only way out of it was to make a special trip to the house to take an actual reading.

    Thanks British Gas.

      You should have let them take you to court, then humiliated them!

    So what would've happened

    if it was just ignored? Would she start getting collection letters for £13,000+ with interest?

    Are even worse, their system will do the wrap-around trick even if the lower reading is entered into the system by the official meter reader on his little tablet machine.

    Of course the first I knew of it was when they raised my direct debit payments to £1500 per month.

    They're all as bad

    nPower sent me my bill prediction for the next 6 months, based on an "estimate" that always seems to be for a family of 6 in a mansion. I sent them the correct readings, they acknowledged receipt of them, and then....kept my bills exactly the same...

    And then when they overcharge, trying to get the money back is fun. Credit against my account? No mate, cheque in the mail, now.

    When I worked for the leccy board, if your meter reading changed by more than 10% they'd schedule you for a meter change.

    As for EDF, well submit your meter readings on line, and then you can try in vain to actually access your bill on line, cos it won't let you register, and they say it takes 2 weeks to reply to their on line enquiries.

    Perfectly standard web design. Can't understand the fuss.

    Now a gas meter with only four digits - *that* is dumb.

    RF meters, energy company's IT systems, and other assorted nonsense

    In the UK, the design of the metering arrangements is such that there are a large number of companies that own the electricity and gas meters. These companies may be your supplier, the local distributor, or someone else. As such, although they could be read remotely through some sort of wireless magic, it'd still be horribly inefficient. The solution will probably come with "smart meters" (much as I hate the term), which will have remote collection (probably via GSM) as standard, with the exceptions having manual readings taken as per the current arrangements. This is broadly what happens for large (>100 kW) industrial customers at the moment - they have meter readings taken daily, broken down by individual half hours, to get a consumption profile through the day.

    The software running the meter data collection algorithm was probably specced out in generic terms by someone who understands WTF is going on. In my experience, this is then taken away by a bunch of consultants (including a normally incompetent Business Analyst), and about 30 Statements of Requirements and other assorted nonsense documents will have been produced. As the consultants don't actually understand the electricity or gas industries, they'll have assumed that meter readings can only go up, and can't go down from reading to reading. Therefore, if you enter a reading of 8500 followed by 8498, it stands to reason that you've used 9998 units of gas/power.

    This will, of course, have made it into the SoR that was produced, but as the only people who would spot that error are being required to review hundreds of the damn things on top of their day jobs, and because Cap Gemini, Capita, Logica, and friends tend to operate in a "if you don't make any comments of this document by noon tomorrow, we'll deem you to have accepted it" world, it's not really that surprising that something like that would get missed. As the testers are testing against the SoRs, instead of using common sense, it passes all stages of functional and non-functional testing.

    Oh, and 9998 units of gas is such a ludicrously small amount in terms of the wholesale markets, (where the smallest amount of gas you can buy is 4,000 therms / 117,288 kWh over a 24 hour period), your meter wrapping around would have been a) ignored as noise, and b) wouldn't have been noticed for about 6 months, until the supplier gets round to reviewing the site's capacity.

    Anonymous for obvious reasons.
