It is an implied term of the contract between customers and their banks and building societies that these firms will keep their customers’ information confidential. This confidentiality is not just confined to account transactions – it extends to all the information that the bank has about the customer.
But from time to time, mistakes happen and – for whatever reason – banks end up releasing information that they should have kept secret. Sometimes, the resulting breach of confidentiality is little more than technical (in other words, nothing really flows from it), but occasionally it can have major consequences.Give a complaint to the Ombudsmen of your banks.
