Hey there! That's not good and could indicate a possible fault with the meter.
Just so you know, I'm only a forum volunteer and therefore can't access your account or make changes. But I can give advice that might help you out. Hope that's OK with you.
I'd like to ask you to do something called a Creep Test really quickly. What this does, is tests to see whether your electric meter is still clocking usage in a situation where it should be recording nothing at all. It doesn't take long to do, but can I please ask that you safely shut down and turn off all sensitive electronics/electricals (such as computers, TV's, games consoles, smart home gadgets, Wi-Fi Router etc.) before you do this, just to keep them safe. You can leave the fridge and freezer on though, along with a few lights - they prove quite helpful for this test!
Once that's all done, here's what you'll want to do for a Creep Test.
- Locate your fuse box/consumer unit and turn off all the power to the entire house - this will only be for a few minutes, so don't worry about spoiling anything in the freezer
- Observe your electric meter for about three to five minutes - you should see no further consumption being recorded after the first minute at most
- Keep an eye out for any red flashing lights on the meter during this time
- After five minutes, feel free to turn the power back on when you're ready
If you don't see any consumption being recorded during the test (aside from the first 30 seconds or so), then your meter has passed the Creep Test and probably isn't faulty. However, if it continues clocking usage despite the fact ALL the power is off, then this is a good indication that your meter has developed a fault. In this case, you'll want to contact Customer Service and request a Meter Accuracy Test, which costs around £160 and you'll need to pay this upfront. If the MAT confirms that the meter is faulty, it will be replaced free of charge immediately. You'll also get the test fee refunded in full and your bills will be regenerated once E.On has been able to figure out how far out the meter was - you'll also be refunded the difference if it was clocking too fast. If it's clocking too slow, you won't be expected to make up the excess either.
Please bear in mind that if the MAT confirms the meter is not faulty, then you'll forfeit the test fee as it won't be refunded, and your bills will stand as valid. Obviously, a Creep Test is free and you can do that yourself pretty easily, so it's recommended to try this first - and only consider requesting a Meter Accuracy Test if the Creep Test confirms that there's a possible fault.
The other thing to consider, is are you definitely sure it's
only those Christmas lights you've had on recently, but otherwise everything's unchanged? It's pretty common to use more energy in winter than in summer, so you may want to check for any other energy guzzlers in the house, just in case.
