I'm trying to help an elderly neighbour, so bear with me that I might not have all the relevant info! She told me that her power bill was very high (double mine and she in in a 1 bed flat vs my 4 bed house). After getting no help for the supplier she contacted the ombudsman. The ombudsman told her someone is tapping her electricity. It seems the matter has stopped there and she doesn't know what to do next.
I also have no idea - I want to help her. She sits in the dark and won't use the electric cooker because she can't afford it.
She rents the house. What do we need to do?
