We have just taken over an HMO with 5 self contained flats. The landlord pays the electric bill for the whole house and the tenants have individual coin meters which the landlord has to empty. Can anyone suggest a better way of doing this. Would it be expensive for us to rewire and only pay electric for the communal areas and let the tenants pay their own individual bills? Would the supplier have to fit new meters or would it be the ladlord?
