Wingsofspeed has misinterpreted the meaning of asking for 3 yr address history. Im sure he isnt meaningly "talking rubbish"
Credit searching is purely for searching individuals against elctoral roll, credit registered at those properties, adverse credit registrations, details of other linked addresses, bankrupcy, IVA and associated individuals,
If a search is conducted against an individual, credit information about other individuals is not shown, unless it it clear that they are associated with the individual being searched, e.g. wife / husband.
Hope that helps
