Folks doing major business with UK firms are literally screwed. The Financial Services Compensation Scheme will not compensate barren claims against insolvent firms, it will compensate small businesses for their losses, but there is a 50 000 limit there, and its not per person, no no, that would be sweet, its per institution. Same for banks (lately there's a trend of going bankrupt rofl). Trickiest thing is yeah, banks owned by the same company/bank/whatever count as one institution.
Talk about ownd.
