As Julian says, just fill out the Notice of Disassociation. It does work, as I too live with my folks, and mum has recently just got her first credit card & mobile phone contract.
Thank you for letting us know that - my hubby is also in the process of contacting the credit reference agencies as we have no financial links - fingers crossed will get the same results if he needs anything.
Onwards and Upwards is the way im going :-0)
From "Moneyworries" to "Movin On" in 3 months is fantastic :-))
