Tenant of many years has now moved on. Found that unbeknown to us, he had swapped the gas and electric meters to prepayment ones. After several weeks of sorting it out, it has become apparent that the tenant left debts of £7000 on the gas and £4000 on the electric bills. I have been told by the energy provider that we don't have to pay the tenant's debts. They have refunded us for the money we have accidentally paid off the tenant's debts when the money we were putting on the meters was being swallowed up.
My question is however, will the house be "Blacklisted" even though the tenant has moved on?
