According to The Fool:

"Banks in the UK are regulated and authorised by the Financial Services Authority (FSA) and must hold a banking licence. However, a number of banks may use the same banking licence - for example, Halifax, Bank of Scotland and Birmingham Midshires are all registered under Bank of Scotland plc. As you can only make one claim for compensation per FSA banking licence, if you should hold accounts with all three you would unfortunately only be able to make one claim.
Interestingly, however, although Sainsbury's Bank is part of the same organisation, as it is registered as Sainsbury's Bank plc and holds its own licence, if you held money here you would be entitled to another claim."
Any comments?

I pulled all my money out of Sainsbury's last week because I didn't realise this until today.
Note to armed robbers: better returns at out of town supermarkets and parking is no problem.
