Being an Authorised Corporate Service Provider

Understanding your role as an Authorised Corporate Service Provider (ACSP), also known as a Companies House authorised agent.

Registering as an Authorised Corporate Service Provider (ACSP) is a new requirement that will help us to know who鈥檚 filing information on the public register.

ACSPs are also known as Companies House authorised agents.

An authorised agent can be a business (for example, a limited company or partnership), or a person who files on behalf of others (sole trader).

To register, agents must be supervised by a UK Anti-Money Laundering (AML) supervisory body. For example, this could include:

  • company formation agents
  • solicitors
  • accountants

Who needs to register as an authorised agent

For now, only agents that plan to聽verify the identity of clients for Companies House聽need to register.

In the future, all agents that file with Companies House on behalf of clients will need to register.

To apply, you must have a senior role in the business. For example, you must be a director if you鈥檙e registering a limited company.

Sole traders can register themselves as an authorised agent.

Once a business is registered, we鈥檒l create an online account for the authorised agent. You鈥檒l be able to add other people who work for the agent to the account.

Read the聽guidance on applying to register as an authorised agent聽to find out how to apply.

Companies House authorised agents must comply with the following legal requirements.

  1. The agent must always be registered with at least one Anti-Money Laundering (AML) supervisory body.
  2. The agent must tell us if there is a change to any of the information we hold about the agent. They must do this within 14 days.
  3. If we request it, the agent must provide more information:
    • about the agent鈥檚 filings with Companies House
    • about identity checks, if the agent verifies someone鈥檚 identity for Companies House
    • to prove the agent is complying with their legal responsibilities
  4. The agent must keep records of any identity checks for 7 years, if they have verified someone鈥檚 identity for Companies House.

If you鈥檙e a sole trader and have registered yourself as an authorised agent, you are responsible for making sure you comply.

For other businesses, all officers are responsible. This means all directors, or anyone whose roles and responsibilities correspond to that of a company director.

The agent will be committing an offence if they do not comply with legal requirements. This means the sole trader, or all company directors (or equivalent) could receive a fine or face criminal prosecution.

We may also suspend or cease (stop) the authorised agent鈥檚 status. This would prevent the agent from being able to file or verify people鈥檚 identities for Companies House.

If we need to suspend an authorised agent

We鈥檒l send an email to the agent鈥檚 correspondence email address with information about what to do next.

We may need to ask the agent to provide more information or records about their filings. The agent will have 28 days to do this.

Users that have been added to the authorised agent account will not be able to access services for the authorised agent while it is suspended. This means they will not be able to:

  • file as an authorised agent
  • verify people鈥檚 identity for Companies House

People who have had their identity verified by the agent for Companies House may need to verify their identity again. We will contact anyone who needs to do this.

We鈥檒l also publish information to show that the authorised agent has been suspended. We鈥檒l publish the agent鈥檚 name, status and the date it was suspended.

If we need to cease an authorised agent鈥檚 status

We will send an email to the agent鈥檚 correspondence email address to let them know we鈥檝e ceased (stopped) their status. This will mean they are no longer registered as an authorised agent with Companies House.

The agent will not be able to file on behalf of clients, or verify people鈥檚 identities for Companies House.

We will:

  • close the agent鈥檚 online account 鈥� any users who have been added will no longer have access
  • publish the agent鈥檚 name and the date we ceased their status
  • contact anyone whose identity the agent has verified, if they need to verify again

An account owner must tell us if there are any changes to the information we hold about the authorised agent. This includes if the agent is no longer registered with an AML supervisory body.

This is a legal requirement. They must do this within 14 days or the agent will be committing an offence.

To tell us about changes, an account owner must email [email protected] using the same email address as they use to sign in. They鈥檒l need to use the subject line 鈥楿pdate ACSP details鈥�.
