On 30 April 2026, the Credit Institutions and Investment Firms (Miscellaneous Definitions) (Amendment) Regulations 2026 (made on 29 April 2026) were published on legislation.gov.uk with an explanatory memorandum.

This instrument restates in legislation certain definitions, such as CRR firm, investment firm and financial institution that are currently defined in the UK Capital Requirements Regulation (UK CRR) and need to be maintained in legislation to ensure that the overall framework and wider legislation for banking prudential regulation continues to operate as intended after the revocation of the UK CRR comes into force on 1 January 2027. The legislation is also intended to improve the clarity of certain definitions and makes them consistent with the approach adopted in UK law, but it is not intended to change the substance of the definitions or alter the wider regulatory framework.
