The Financial Services Compensation Scheme (FSCS) is the UK's statutory deposit insurance and investors compensation scheme for customers of authorised financial services firms. This means that FSCS can pay compensation if a firm is unable, or likely to be unable, to pay claims against it. The FSCS is an operationally independent body, set up under the Financial Services and Markets Act 2000 (FSMA), and funded by a levy on authorised financial services firms. The scheme rules of the FSCS are made by the Financial Conduct Authority (FCA) and are contained in the FCA's Handbook. The FCA also appoint its Board and the FSCS is ultimately accountable to the FCA. The scheme covers deposits, insurance policies, insurance brokering, investments, mortgages and mortgage arrangement.

FSCS is free to consumers and, since 2001, has helped more than 4.5 million people and paid out more than £26 billion. Since 31 December, 2010, maintaining a single customer view has become mandatory for United Kingdom banks and other deposit takers due to new rules introduced by the FSCS.
