No - but should you apply for credit at some future date, such as mail order goods, your personal details'd be checked. Unless you altered your date of birth and other things, they could trace you that way. Also, you have to be living at whatever address you apply from for 3 years, and if it's less than that, you have to provide a previous address. The Powers That Be have all your personal info on record, & your credit worthiness'd be checked out - as well as the details you'd provided. I'd say it's not worth it, because you might get away with it for a while, but they'd find you eventually. Having said that, I know someone whose house was repossessed through non-payment of mortgage. She owed thousands, and hid behind new addresses and names. She then married, had a legitimate new identity, and after 8 years seems to've got away with it.
