ACSP is a term that has started to appear much more frequently in discussions about company formation, compliance, and anti money laundering, and it has caused a fair amount of confusion. I am often asked what an ACSP actually is, who needs one, and whether it changes how directors and business owners interact with Companies House.

ACSP stands for Authorised Corporate Service Provider. It is not a new type of company or business structure, but a regulatory status given to certain organisations and professionals who are allowed to carry out specific services on behalf of companies and individuals. Understanding what an ACSP is matters because it directly affects how companies are formed, how filings are made, and who can act on your behalf.

In this article I will explain what an ACSP is, why the role has been introduced, who can be an ACSP, what they are allowed to do, and what this means in practice for limited companies, directors, and business owners. I will also cover common misconceptions and practical implications, so you can see clearly whether an ACSP is relevant to you.

What ACSP stands for

ACSP stands for Authorised Corporate Service Provider.

An ACSP is an organisation or professional that has been authorised to carry out certain corporate services while meeting enhanced identity verification and anti money laundering standards.

In simple terms, an ACSP is a trusted intermediary that can deal with company filings and identity checks on behalf of others.

ACSPs are closely linked to reforms designed to improve transparency, reduce fraud, and strengthen trust in the UK company register.

Why ACSPs have been introduced

The introduction of ACSPs is part of a wider reform of the UK corporate system.

For many years, it was relatively easy to form companies, file documents, and make changes at Companies House with very limited identity checks. While this made the system fast and accessible, it also left it open to abuse.

Problems that the reforms aim to address include:

• Fake directors and shareholders

• Companies set up using stolen identities

• Shell companies used for fraud or money laundering

• Poor quality or misleading information on the public register

ACSPs are intended to act as a filter and safeguard, ensuring that individuals and businesses are properly identified before certain actions are taken.

What an ACSP actually does

An ACSP is authorised to carry out identity verification and company related services on behalf of clients.

Depending on the specific permissions and regulations in force, this can include:

• Verifying the identity of directors and persons with significant control

• Filing information with Companies House on behalf of clients

• Forming companies

• Submitting confirmation statements and changes

• Acting as an intermediary between clients and Companies House

The key point is that an ACSP is trusted to verify identities to the required standard, rather than leaving this entirely to Companies House or the individual.

Who can be an ACSP

Not just anyone can become an ACSP.

ACSPs are typically organisations or professionals that are already subject to strict regulation and anti money laundering rules.

Examples include:

• Accountants and accountancy firms

• Company formation agents

• Legal professionals

• Corporate service providers

To be authorised, an ACSP must be properly supervised for anti money laundering purposes, usually by a recognised supervisory body.

This often includes firms already overseen by HMRC or professional bodies.

The link between ACSPs and anti money laundering rules

ACSPs sit squarely within the UK’s anti money laundering framework.

They are expected to:

• Carry out customer due diligence

• Verify identity using reliable evidence

• Understand the nature of the client relationship

• Monitor for suspicious activity

• Keep proper records

These obligations already apply to many professionals, but ACSP status formalises their role in the company registration and compliance process.

In effect, the government is relying on regulated professionals to act as a front line defence against misuse of the company register.

ACSPs and identity verification

One of the biggest changes associated with ACSPs is identity verification.

Under the reformed system:

• Directors and persons with significant control must have their identities verified

• Verification can be done directly or through an ACSP

• An ACSP can confirm to Companies House that checks have been completed

This means that instead of every individual interacting directly with Companies House systems, many will rely on an ACSP to handle verification and submission.

For business owners already working with accountants or company service providers, this may feel like a natural extension of existing processes.

What an ACSP is not

There are several misconceptions about ACSPs that are worth clearing up.

An ACSP is not:

• A new type of company

• A replacement for Companies House

• Mandatory for every business interaction

• A guarantee that no fraud will ever occur

ACSPs are part of a layered system of checks, not a silver bullet.

Do all companies need an ACSP

No, not every company will need to use an ACSP.

Individuals can still deal directly with Companies House for many matters. However, where identity verification is required, using an ACSP may be simpler and more efficient, particularly for those who already use professional advisers.

In practice, many companies will choose to use an ACSP because:

• They already work with an accountant or adviser

• They want reassurance that filings are correct

• They prefer not to deal with verification systems themselves

Over time, using an ACSP may become the default choice for many businesses, even where it is not strictly required.

ACSPs and accountants

For accountants, ACSP status is particularly relevant.

Many accountancy firms already:

• Form companies for clients

• Act as registered office addresses

• Submit filings to Companies House

• Carry out identity checks under AML rules

ACSP status formalises this role and allows accountants to continue acting on behalf of clients under the new verification regime.

From a client perspective, this often means less disruption, as existing advisers can continue handling compliance.

ACSPs and company formation

Company formation is one of the areas most affected by ACSPs.

When forming a company:

• Directors and shareholders must be properly identified

• Information submitted must be accurate and verified

• An ACSP can handle this process end to end

This helps reduce the risk of companies being formed with false details and strengthens the integrity of the register.

How ACSPs affect directors and PSCs

For directors and persons with significant control, ACSPs change how identity verification works.

Instead of navigating verification alone, individuals can:

• Provide documents to an ACSP

• Have checks carried out professionally

• Rely on the ACSP to confirm compliance

This can be particularly helpful for those who are less comfortable with digital systems or who have more complex arrangements.

Record keeping and responsibility

Using an ACSP does not remove responsibility from directors.

Even where an ACSP is involved:

• Directors remain legally responsible for accuracy

• Information provided must be truthful

• Obligations under company law still apply

An ACSP can help reduce errors and improve compliance, but it does not replace director responsibility.

Costs and commercial considerations

ACSP services are not free.

Costs vary depending on:

• The type of service provided

• The complexity of the business

• Ongoing compliance needs

For many businesses, the cost is modest compared to the time and risk saved by using a regulated intermediary.

How ACSPs fit into wider company law reform

ACSPs are not an isolated change. They form part of broader reforms aimed at:

• Improving data quality at Companies House

• Reducing economic crime

• Increasing trust in UK corporate information

• Enhancing enforcement powers

Together, these changes mark a shift from a purely administrative register to a more actively regulated system.

Common questions I hear about ACSPs

I am often asked whether ACSPs mean more red tape. In some respects, yes, there are more checks. However, the intention is to move that burden onto regulated professionals rather than individual directors wherever possible.

Another common question is whether small businesses will be disadvantaged. In my experience, small businesses already working with accountants are likely to find the transition straightforward.

How I explain ACSPs to clients

When clients ask me what an ACSP is, I usually describe it as a trusted gatekeeper.

The role exists to ensure that the people behind companies are real, identifiable, and accountable. For honest businesses, this should feel like sensible housekeeping rather than an obstacle.

Final thoughts

An ACSP, or Authorised Corporate Service Provider, is a regulated organisation that can verify identities and carry out company services on behalf of others under enhanced rules. It is not a new business structure, but a key part of modernising the UK corporate system.

For many directors and business owners, ACSPs will simply formalise what already happens when working with accountants, lawyers, or company service providers. The goal is greater transparency, better data, and reduced misuse of the company register.

In my view, ACSPs are less about adding complexity and more about restoring confidence in how companies are formed and managed. If you already work with a professional adviser, you are likely to interact with the ACSP framework without even realising it.
