Question

Electricity meter still recording high usage (20 kWh/day) even when fuse box is completely off

Hi everyone,

I’m looking for advice because something doesn’t seem right with my electricity usage.

I live in a flat, and until recently our usage was around 100 kWh per month. However, it has suddenly increased to around 20 kWh per day, which is a huge jump.

To investigate, I turned off the fuse box inside the flat (old-style fuse box with removable fuses), so everything in the flat should be off. Despite this, the electricity meter is still recording usage.

There is no main isolator switch installed — just the meter and the sealed main fuse. Even with all circuits off in the flat, the meter continues to increase.

The property is a flat with neighbours next door, upstairs, and nearby, so I’m concerned it could be:

  • Something wired before the fuse box (e.g. immersion heater or similar), or
  • A possible crossed meter / shared supply issue

Has anyone experienced something similar or know what could cause this?

Any advice on what to check next or how to confirm the source would be really appreciated.

Thanks in advance!

That certain sounds like something needs checking.

This might help you to check some items about your account and the meter

Hi ​@V1lm4 and a warm welcome to the OVO Forum.

 

I’m sorry to hear of what’s happening here. It does indeed sound like it could be a ‘crossed meters’ situation. Have a look at the article I wrote that ​@BPLightlog has linked above. It contains some tests you can do yourself to help ascertain what the problem might be, and you’ll then need to contact our Support Team about it.

 

Hopefully this is sorted for you asap!
