I have a 3 Phase supply to my house. Years ago it had a commercial site here hence the 3 phase. I get humongous electricity bills. Scottish power have finally said they a have been billing me incorrectly. Before all this lockdown they were ringing every week for a reading. Told me to cancel direct debit to them until they could sort it out. For the last two weeks I haven’t been able to speak to them ..no one in the call centre because of covid19. I have been taking the reading and keeping them. I took a reading last week the top figure was 563999 this week it is 564696. Does that mean I’ve used nearly 700 kw ? Surely not !! There are no decimal points on my display but I’m praying that the last digit is ignored on this type of meter and the usage is 70kw which would be about right because there is only Me and my husband living in the house. Oil for cooking (aga)and  oil central heating. 
Anyone out there help me on this one ? 

Kind regards 

Fiona
