This Practice Note explores the requirements of chapters 15, 16 and 17 of the Financial Conduct Authority (FCA) Handbook’s Supervision Manual (FCA SUP 15, 16 and 17A) in relation to standing data and keeping it up to date. The PRA works closely with the FCA in the collection and management of regulatory data. Much of the regulatory data for PRA firms continues to be collected by the FCA. This includes reporting via the FCA’s RegData system, the submission of firms’ controllers and close links reports and the reporting of changes to firms’ standing data. The Practice Note also outlines the FCA RegData and Connect systems and the Financial Services Register. The consequences of providing inaccurate information are also addressed. It is very important that the standing data that the FCA and/or PRA hold about firms is accurate and up-to-date. Each authorised firm is responsible for ensuring that it discloses any changes in its standing data to its relevant regulator.
