Section 51 of, and Schedule 2 to, the Economic Crime and Corporate Transparency Act 2023 (c. 56) (abolition of certain local registers) made amendments to Part 21A (information about people with significant control) of the Companies Act 2006 (c. 46, “the 2006 Act”) to replace rules that required companies to maintain “local” registers of their registrable persons and registrable relevant legal entities (see section 790C of the 2006 Act for definitions of “registrable person” and “registrable relevant legal entity”, which are together also known as persons with significant control, or “PSCs”) with rules that require companies to notify the registrar of information about PSCs. These Regulations make amendments and additions to those new rules.
