Recent Regulatory Changes for UK Private Limited Companies (Ltd): 2023–2025

Overview

The United Kingdom has implemented substantial reforms to company law through the Economic Crime and Corporate Transparency Act 2023 (ECCTA). These changes affect all private limited companies (Ltd) registered at Companies House.

1. ECCTA 2023 — Identity Verification (November 2025)

Mandatory identity verification (IDV) for all company directors, persons with significant control (PSCs), and persons filing on behalf of companies became operational in November 2025. All new incorporations require IDV as part of the filing process. Existing directors and PSCs must complete IDV within a transitional period. Failure to verify identity prevents filing of documents at Companies House and may result in the company being struck off.

2. Abolition of Local Registers (November 2025)

The obligation for UK private limited companies to maintain their own local registers of directors, PSCs, and members was abolished with effect from November 2025. Companies House now maintains the sole authoritative statutory register. Companies are no longer required to keep or update local copies.

3. Authorised Corporate Service Providers (March 2025)

From March 2025, only Authorised Corporate Service Providers (ACSPs) — agents registered with and supervised by an AML supervisory body — may file incorporation documents and certain changes on behalf of third parties at Companies House. Private firms offering company formation services must either obtain ACSP status or cease offering these services.

4. Failure to Prevent Fraud Offence (September 2025)

The Failure to Prevent Fraud offence under the ECCTA 2023 entered into force in September 2025. Large UK private limited companies are criminally liable if a person associated with the company commits a fraud offence that benefits the organisation, unless the company can demonstrate it had reasonable fraud prevention procedures in place. A company is considered large if it meets two of: more than 250 employees, more than GBP 36 million turnover, or more than GBP 18 million total assets.
