Electric metre fault

netrcyluam

Hi
  I have what I believe is a faulty electric metre in my home, apologies for length of query.

I turned main supply breaker off which is before the original metre an the metre led light kept flashing constantly.
I raise with energy supplier who requested photos/video which they received. Supplier fitted a check metre to run alongside original metre in Oct 2022 as a check. The original metre has to date recorded 947 units more than check metre.
Supplier was supposed to remove metre after 6 weeks but it's still in.
Therefore this confirms my suspicion of a fault
I've been to ombudsman & sent them evidence ( photos/video/readings) they have adjudicated & informed supplier to get a independent examination done on metre.

Supplier contractors turned up at property & had wrong job booked in but when I asked engineer about a test he said metre will get chucked in box in van & go back to their returns store with rest of metres. He knew nothing about a test. As wrong job booked he said he could do anything.

Need some advice how do I know if the metre test / examination is independent or if it is just done by supplier contractors which I suspect they will say metre is ok, as I think the metre has been faulty by possible years if not months therefore may have financial implications for supplier.

Just to note I have asked for a determination test to be carried out but I don't think they'll do one.

Thanks in advance for replies.

The faulty metre was probably too big to work properly. Our meter's only about 60cm.

.

Could you post a photo of the wiring layout? I'm surprised by the comment that your isolator is before the meter, normally it would be after.
