What does ACSP stand for? This guide explains what an Authorised Corporate Service Provider is, how ACSP status fits into Companies House identity verification, and what overseas founders should check before choosing a nominee director provider. #ACSP #NomineeDirector #UKCompanyFormation

What ACSP means in plain English

ACSP means Authorised Corporate Service Provider. According to Companies House, ACSPs are also known as authorised agents. They are agents such as accountants, solicitors or company formation agents that have registered with Companies House to file or complete other activities on behalf of clients.

In simple terms, an ACSP is relevant when a provider is helping with:

• Companies House identity verification
• authorised-agent processes
• future client filing workflows through the ACSP regime
• corporate setup support where Companies House compliance is part of the service

This matters because the UK company-law reform programme has moved identity verification into the centre of Companies House compliance. From 18 November 2025, identity verification became a legal requirement, with a 12-month transition period for existing directors and PSCs to comply by their due dates. Companies House also says that, from no earlier than November 2026, businesses will need to be registered as an ACSP to file on behalf of clients through that authorised-agent route.

So, when a provider says it can help you navigate Companies House verification or future filing requirements, the sensible next question is whether it is actually registered as an ACSP and how that fits into the service you are buying.

For overseas founders using non-resident company formation services or a UK nominee director service, this can be a particularly useful distinction to understand early.

Why ACSPs should be used

ACSPs should be used where a client wants a professional, supervised route into Companies House identity verification and related authorised-agent processes. Companies House says a person can verify directly using GOV.UK One Login or ask an ACSP to verify on their behalf. For many overseas founders, nominee-director clients and corporate-service users, that second route can be helpful when working with an established provider as part of a wider company-formation or compliance service.

They can also be useful because Companies House requires ACSPs to be supervised by a UK anti-money-laundering supervisory body and to comply with defined legal responsibilities if they verify identity. That does not remove the need for due diligence, but it does mean the provider is operating inside a formal regulatory framework rather than simply describing itself as a general corporate-services business.

Another practical reason to use an ACSP is accessibility. Companies House says an ACSP can verify someone’s identity from any country, provided the agent is properly authorised and supervised in the UK. For non-UK residents, that can make the process easier to manage where UK company formation, nominee-director support and Companies House compliance are being handled together.

Why ACSP status matters for nominee director services

ACSP status does not mean the provider is itself the nominee director. It means the provider has a specific authorised-agent role in the Companies House system. In the nominee-director market, this matters because onboarding often overlaps with identity verification, PSC compliance, registered office arrangements, and wider company-formation support.

If a nominee director provider says it can manage Companies House identity verification as part of its service, it should be able to explain whether it is acting as an ACSP, what evidence it needs from the client, and what remains the responsibility of the director, PSC or beneficial owner.

This is especially relevant where the same provider also offers a registered office or service address, because overseas founders often buy a bundle of compliance services at once and assume all providers operate under the same authorisations. They do not.

ACSP status also does not remove the ordinary legal duties of a director. Companies House guidance makes clear that directors still owe the seven general duties under the Companies Act 2006, including acting in the company’s best interests and exercising independent judgment. That remains true even if somebody else tells the director what to do. So, in nominee structures, the legal nature of the office still matters.

What legal responsibilities an ACSP takes on

Companies House says an authorised agent must remain registered with at least one UK AML supervisory body, tell Companies House about changes to its details within 14 days, provide further information when requested, and keep identity-check records for 7 years if it has verified someone’s identity for Companies House.

These are not optional housekeeping steps. Companies House states that failing to comply can be an offence. A sole trader, or all company directors or equivalents responsible for the authorised agent, could face a fine or criminal prosecution. Companies House may also suspend or cease the agent’s status, which would stop it from verifying identities or filing as an authorised agent.

From a client’s point of view, that means ACSP status should be treated as a meaningful compliance role. It is not just a line on a website footer.

ACSP at a glance

The table below summarises what ACSP status does and does not mean for overseas company owners and nominee-director clients.

How to check an ACSP properly

Companies House publishes a list of ACSPs and also publishes a list of ceased or suspended ACSPs. However, Companies House states that the main ACSP list may not include every registered agent and may be incomplete or out of date, because it is not updated on a set schedule. It also says it does not endorse or recommend the agents on the list.

So a sensible due-diligence approach is to combine the public list with direct provider checks. Ask what services the provider offers, whether it verifies identity remotely, what its terms are, and whether it explains director duties and PSC disclosure clearly and lawfully.

Key takeaway for overseas founders

ACSP stands for Authorised Corporate Service Provider. In today’s Companies House framework, that means a provider authorised to operate in a defined part of the identity-verification and authorised-agent system, provided it is already supervised by a UK AML body. For overseas founders, that makes ACSP status an important quality and compliance checkpoint when comparing nominee director, company formation and broader corporate services.

It is not the only thing to check, but it is now one of the clearest questions to ask: if a provider says it can handle Companies House identity verification or related compliance workflows, is it registered as an ACSP, and can it explain exactly what that means for your company?
