Authorised Corporate Service Provider (ACSP) – Notary Public London

At Notary Public London, we are formally recognised as an Authorised Corporate Service Provider (ACSP), approved and regulated to act directly with Companies House.

As both a Solicitor and Notary Public, Charles Guthrie is authorised to verify identities, submit filings, and ensure companies remain compliant with the Economic Crime and Corporate Transparency Act 2023.

What is an ACSP and Why Does It Matter?

An Authorised Corporate Service Provider (ACSP) is an individual or firm supervised by a professional body and approved by Companies House.

Only ACSPs are permitted to:

• Verify the identities of company directors, officers, and Persons of Significant Control (PSCs)
• Submit filings and statutory documents to Companies House
• Confirm compliance with the new legal requirements designed to prevent fraud, money laundering, and misuse of UK companies

This change means that from 2024 onwards, many company filings cannot be submitted directly — they must go through a registered ACSP like Notary Public London.

Frequently Asked Questions (ACSP – Companies House)

What is an ACSP at Companies House?

An Authorised Corporate Service Provider (ACSP) is a regulated professional authorised by Companies House to file company documents and verify identities on behalf of clients.

Why do I need an ACSP?

Under the Economic Crime and Corporate Transparency Act 2023, many company filings can no longer be submitted directly by individuals. They must be filed through an ACSP to ensure verified, trusted submissions.

Can I file my own documents with Companies House?

In most cases, no. From 2024, identity verification and many filings must be submitted via an ACSP. This applies to UK and overseas directors, PSCs, and officers.

How quickly can you act as my ACSP?

We can act immediately. Identity checks and filings are usually completed within the same working day, subject to receipt of all required documents.

Do you offer ACSP services outside London?

Yes. While we welcome walk-in clients at our central London office, we also serve businesses across the UK and internationally. Documents can be sent by Royal Mail Special Delivery, DHL, or FedEx. Remote verification can also be arranged.

How much does ACSP service cost?

Fees vary depending on the type and number of filings. We provide clear, fixed quotes in advance. Please contact us for a free estimate.
