I had a kilowatt meter place in a granny flat I had in order to make two tenancies. I asked the real estate agent to have the electric bill sent to them and to read the meters and issue separate accounts. The boys moved moved in the the big house and connected the electricity in their names. The real estate agent told me I asked her to change it no matter the new lease costs. 18 months later she contacts me again and tell me a dispute has arisen over the account, the boys claiming injustice. During this call she tell me the new lease never happened. The boys given notice leave owing rent and property damage. Detesting the situation split everything properly and created a separate billing. Two months later the R/E gets a letter from the boys claiming the set up was illegal and wanting 5k back on the electricity? I though the set-up was (not ideal) but still within allowable parameters, will I be liable?
