Understanding Authorised Corporate Service Providers (ACSPs): A Guide to Companies House Requirements
What is an Authorised Corporate Service Provider (ACSP)?
Companies House has introduced new regulatory requirements for third-party service providers who conduct identity verification checks on behalf of clients when submitting applications. Under these regulations, both individuals and corporate entities must register as Authorised Corporate Service Providers (ACSPs).
Registration as an ACSP will become mandatory from 18 November 2025 and establishes a new standard for identity verification processes that all qualifying organisations must meet.
Who Needs to Register as an ACSP?
Any individual or organisation that performs anti-money laundering (AML) activities and conducts identity verification checks for clients must register as an ACSP. This includes:
- Company formation agents
- Accountants
- Solicitors who assist clients with UK company registration
Important: You are only eligible to register as an ACSP if your organisation is supervised by a recognised Anti-Money Laundering supervisory body. A comprehensive list of approved supervisory bodies is available on the UK Government's AML registration page.
How to Register as an ACSP with Companies House
The registration process must be completed by a senior staff member, such as a sole trader or company director. Registration requires:
- Evidence of your AML registration
- Payment of the £55 registration fee
Once submitted, Companies House will review your application and, upon approval, activate your ACSP account. After activation, additional staff members who will be conducting identity verification checks can be added to the authorised agent account.
Is ACSP Registration Mandatory?
If your organisation intends to conduct identity verification checks on behalf of clients, ACSP registration is mandatory, and you must comply with the new identification verification standards. These regulations come into force on 18 November 2025.
Organisations that choose not to register as an ACSP will be unable to complete identity checks on behalf of clients. In these cases, clients will need to complete the verification process directly with Companies House using the GOV.UK One Login system, which provides a unique code as evidence of completed identity checks.
