In the UK, there is no check on the name and address field at all. You can put "Micky Mouse" there if you like, and nobody will notice.
Furthermore, almost all UK bank account numbers do not have a checksum - so a typo in the account number will not be automatically detected. If you are lucky, the typo'ed account number will not correspond to an account number, and the receiving bank will bounce it back. Typically however, the money just goes into the wrong account.
Whether you are entitled to claim the money back is a rather complicated legal question, but the short answer is "yes, providing you do so quickly". However, banks don't make it particularly easy to do so and may require you to go to court (you may even need a court order to force the receiving bank to identify who you have to sue - a "Norwich Pharmacal" order). There have been a number of such cases highlighted in the media, and there have been agreements to improve the ability to recover the money.
But if you are transferring a large sum, triple check the account number.
