Applying to register as a Companies House authorised agent
Source: gov.uk (2025-06-26)

How to use our service to register as as an Authorised Corporate Service Provider (ACSP), also known as a Companies House authorised agent.

To verify the identity of clients for Companies House, agents must register as an Authorised Corporate Service Provider (ACSP). This is also known as an authorised agent.

The agent must already be registered with an Anti-Money Laundering (AML) supervisory body. Not all businesses are eligible for money laundering supervision. For more information, read the guidance on anti-money laundering registration (https://www.gov.uk/anti-money-laundering-registration).

Apply to register as a Companies House authorised agent (https://find-and-update.company-information.service.gov.uk/register-as-companies-house-authorised-agent).

1. Check you can apply

If you are a sole trader, you can register yourself as an authorised agent.

To register a business as a Companies House authorised agent, you must have a senior role. You must be one of the following:
- director
- general partner
- partner
- member
You’ll be able to add other people who work for the business to the agent account once it’s registered.

If you’re registering a corporate body

If the body is managed by its members, you must be a member of the body. Otherwise, you must be the equivalent of a director.

If you’re registering an unincorporated entity

If the body is managed by its members, you must be a member of the body. Otherwise, you must be a member of the governing body.

2. Verify your identity

You’ll need to verify your identity for Companies House before you can use the online service to register an authorised agent.

If you have not verified before you start your application, we’ll ask you to do it when you start.

3. Tell us about the business

The details you need to give will depend on the type of business you’re registering.

We’ll also ask which business sector (https://www.gov.uk/guidance/money-laundering-regulations-who-needs-to-register) you work in. This is optional.

We’ll check your AML supervisory body holds the company name that’s shown on the Companies House register (https://www.gov.uk/get-information-about-a-company). If the AML registration is in a different name, you’ll need to update this before you apply.

You’ll need to tell us the:
- names of the supervisory bodies the business is registered with

How to find your membership number

Depending on your supervisory body, you may be able to find this on:
- your practising certificate
- communications from the supervisory body
- the supervisory body’s online register
Your AML supervisory body may have a different name for it, such as:
- a firm ID or number

You should contact the AML supervisory body if you need to check your details.

You’ll need to confirm you accept your legal responsibilities as an authorised agent.

Once registered, authorised agents must:
- always be registered with at least one UK AML supervisory body
- tell us about any changes to the authorised agent’s details
