    Good evening

    I have a meter that is for the landlords supply in a block of 4 flats, its been in situ for around 16 years and consumption has been around 450 units per annum, the last meter read was in january this year when it read around 8000 at the latest read this has jumped to 58000 ish, effectively the meter has suddenly gained 50000 units in 6 months.
    There is no reason for this to have happened , the circuits covered by the meter are for fire alarm, door entry, tv/ satellite system, lighting . No signs of any tampering any there have been no problems with any of the circuits. Flats are checked regularly and no sign of " cultivation" but this would require a circuit to be accessed and there is no sign one has.
    Have meters been known to behave in such an odd manner? Any suggestions as to what to look at? Building has an EIRC that was done last year and the electrician is coming round to check things out.
    Trying to be as informed as possible before comtacting my supplier.

    Many thanks

    That's either been tapped for one mighty weed farm or it's broken.

    Is it digital or an old spinny dial one? And whichever, is it currently going like the clappers or just ticking over at 1 unit per day?

    It's a digital, currently plodding along at around 1-2 units a day. Pretty sure it's as it was since imstalled in around 2001. Seems to have magically aquired 50k. Fag packet calcs suggest its been drawing 80 amps since january through breakers totalling 46 amps

    Sounds like probably a fault has resulted in some of its memory getting scrambled. Depending on how it's implemented this could just change a digit or add a power of two to the reading, or something more complex. This could either be a hardware fault or a "single event upset" - https://en.wikipedia.org/wiki/Single_event_upset

    If you report it they'll often put another meter in series with it as a check, but with a single event upset it may well never occur again. Perhaps get an independent inspection if the electricity company dispute it?
    Any electrical storms locally between the last good reading and you noticing the outrageous reading? Good luck with the electric co.. With a bit of luck the over reading is so outrageous that it can only be an error, e.g. if the additional was only 5000 units over you would have a much harder fight on your hands.

    Thanks gents, got an electrician coming round to give everything a check, then i'll contact supplier. Hopefully common sense will prevail.

    Good evening

    Electrician turned up to give things the once over, circuits etc fine, however the meter would appear to be the issue, having turned off the main breaker in the consumer unit, when it was turned back on the meter now has a blank display. So should be an interesting talk with supplier in morning.
    Ask for a refund!

    The meter is upstream of the consumer unit, no? Don't forget compensation for your time and the electrician when you ask for the refund!

    One of our meters did that.
    I reported it straight away. They arranged a replacement. It took several weeks.
    It so happened I had a 'the day before' reading for the meter (a sensible one in our case) and they were happy to use that as a final reading for the old meter.
    I expected that they'd want to do an "estimated" use for the period between the meter packing in & replacement, but no, they simply ignored that period.

    In your case you might prefer not to mention your recent reading!

    Finally all sorted, after several calls emails etc, where i'm repeatedly told meter won't have failed. Engineer eventually arrives takes a look shrugs and says "happens regularyly" 2 weeks later meter changed. A few emails exchanged regarding good will for my wasted time and consumption and standing charge have been waived for 8 months in good will. A pity that as its the landlords supply it only uses 1.5 units a day.
    Thanks to those that replied.
