ECCTA & Limited Partnerships: New Transparency Rules for TCSPs

Setting the Scene: Why ECCTA is Transforming UK Limited Partnerships

The UK's corporate landscape is undergoing its most significant overhaul in over a century, driven by the Economic Crime and Corporate Transparency Act 2023 (ECCTA). This landmark legislation aims to bolster the UK's fight against economic crime, enhance corporate transparency, and prevent the misuse of UK entities. While much attention has rightly focused on companies and LLPs, the ECCTA introduces particularly profound changes for UK Limited Partnerships (LPs).

Historically, LPs, governed by the outdated Limited Partnerships Act 1907, have been criticised for their opacity and susceptibility to illicit activities, including money laundering and fraud. The ECCTA directly addresses these vulnerabilities, fundamentally reshaping how LPs are registered, governed, and monitored. For Trust and Company Service Providers (TCSPs), these reforms represent a critical shift, demanding proactive engagement and a thorough understanding of the new compliance obligations.

The New Mandate: Authorised Corporate Service Providers (ACSPs) and LP Filings

One of the most impactful changes for ECCTA Limited Partnerships is the mandatory requirement for all filings at Companies House to be submitted by an Authorised Corporate Service Provider (ACSP). This is a significant departure from previous arrangements and underscores the government's commitment to ensuring the accuracy and legitimacy of information on the public register. Companies House will now reject any applications or filings that do not come via an ACSP.

For TCSPs already registered as ACSPs, this solidifies your pivotal role as gatekeepers of corporate data. For those not yet registered, it becomes an urgent priority. To qualify as an ACSP, your business must be supervised by a UK Anti-Money Laundering (AML) supervisory body, such as HMRC or the FCA. This requirement links directly to your existing TCSP AML supervision obligations, ensuring a regulated professional is responsible for verifying client information before it reaches Companies House.

ACSPs will bear significant responsibility. You must keep records of identity checks for at least seven years, ensure the accuracy of information filed, and notify Companies House of any changes to ACSP details within 14 days. It's crucial to note that Companies House's identification standards for ACSPs are distinct from the risk-based approach typically adopted under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 (MLR 2017). Therefore, TCSPs must familiarise themselves with both sets of requirements.

Establishing a UK Connection: Registered Office and Email Requirements

To ensure LPs maintain a genuine and verifiable link to the UK, the ECCTA introduces strict new rules regarding their registered office and email addresses. This directly addresses concerns about shell companies and untraceable entities.

The 'Appropriate Address' Standard

Under the ECCTA, every LP must maintain a registered office that is an 'appropriate address' in the part of the UK where the partnership is registered. This means an LP registered in England must have an address in England, for example.

An address is considered 'appropriate' if:

• Any document delivered to it would reasonably be expected to come to the attention of a person acting on behalf of the LP.
• The delivery of documents to the address is capable of being recorded by an acknowledgment of delivery.
• It is not merely a Post Office (PO) box number.
• It is either the principal place of business of the LP, the usual residential address of an individual general partner, the registered or principal office of a legal entity general partner, or the address of an ACSP acting for the LP.

This change has significant implications for TCSPs providing registered office address rules and mail forwarding compliance services. Digital mail handling solutions can be invaluable here, providing clear audit trails of document receipt and forwarding, which helps evidence that the 'appropriate address' criteria are met.

Mandatory Registered Email Address

In addition to a physical registered office, LPs will also be required to provide and maintain a registered email address. This address must be one where communications from Companies House can reasonably be expected to come to the attention of a person acting on behalf of the LP. Importantly, this email address will not be made public on the Companies House register.

Unpacking Transparency: Enhanced Information for LP Partners and PSCs

The ECCTA introduces a substantial expansion of the information that LPs must file with Companies House, moving far beyond the minimal details previously required. This aims to shed light on beneficial ownership Limited Partnerships structures and their true controllers.

Detailed Partner Information

A new Schedule to the Limited Partnerships Act 1907, inserted by the ECCTA, specifies the extensive information to be notified to Companies House about an LP's partners and proposed partners.

• For individual partners (general or limited): Full name, date of birth, nationality, former names, usual residential address, and the part of the UK or other country/state where the individual is usually resident. For individual general partners, a service address will also be required.
• For legal entity partners (general or limited): Corporate or firm name, principal or registered office address, service address, the legal form of the entity, the law by which it is governed, and if applicable, the register it is entered in (including outside the UK) along with its registration number.

Any changes to this required information must be notified to Companies House within 14 days of the change.

Registered Officers for Corporate General Partners

Where a general partner of an LP is a legal entity, it will be required to appoint and maintain one of its managing officers as a contactable 'registered officer'. This individual's identity must be verified. If there are multiple corporate managing officers, a named contact must be provided for each. This directly aligns with the broader Companies House identity verification regime introduced by the ECCTA, ensuring accountability for corporate actors.

Navigating the Timeline: Key Deadlines for Limited Partnership ECCTA Changes

While the ECCTA received Royal Assent in October 2023, its provisions are being implemented in phases. For the specific reforms impacting ECCTA Limited Partnerships, the government has indicated that these will come into force "no earlier than the end of 2026" or "by 1 April 2027", pending the necessary secondary legislation.

Companies House has committed to providing at least six months' notice before these new requirements take effect. Once the measures are implemented, existing LPs will typically have a six-month transitional period to bring themselves into compliance.

Key Takeaway: Although the exact commencement date is yet to be confirmed, TCSPs and their LP clients should consider late 2026/early 2027 as the critical timeframe for full compliance. Proactive preparation during 2025 and 2026 is essential to avoid penalties and ensure a smooth transition.

It's also worth noting that the wider identity verification requirements for directors and Persons of Significant Control (PSCs) of companies and LLPs became mandatory in November 2025, with a 12-month transition period for existing individuals, ending around November 2026. The LP reforms will integrate with this broader IDV framework.

Strategic Preparation for TCSPs: Guiding Your LP Clients Through Reform

The upcoming ECCTA changes for LPs present both challenges and opportunities for TCSPs. By understanding the new requirements and preparing effectively, you can solidify your role as a trusted compliance partner.

1. Review Your LP Client Portfolio: Identify all Limited Partnerships you administer. Categorise them by jurisdiction (England, Wales, Scotland, Northern Ireland) and assess their current compliance status against the upcoming requirements.

2. Enhance Client Due Diligence (CDD): The expanded information requirements for partners mean you'll need to collect more granular data. Review your onboarding and ongoing monitoring processes to ensure they capture all necessary details, including former names, nationalities, and usual residential addresses for individuals, and comprehensive details for corporate partners. This reinforces your existing AML obligations under MLR 2017.

3. Confirm ACSP Registration: Ensure your firm is fully registered as an ACSP with Companies House and is supervised by an appropriate AML body. Understand the specific Companies House identity verification standards, which may go beyond your standard AML/KYC checks. Remember, all future LP filings must go through an ACSP.

4. Address Registered Office & Email Compliance: Advise clients on the 'appropriate address' rules. For LPs using your registered office service, ensure the address meets the new criteria and that your internal processes for handling and acknowledging mail are robust. Implementing digital mail handling solutions can provide the necessary audit trails and efficiency. Ensure a compliant registered email address is in place for each LP.

5. Prepare for Annual Confirmation Statements: Inform LP clients about the new annual filing requirement. Establish a system to gather and verify the necessary information for these statements well in advance of their due dates.

6. Educate Your Team: Provide comprehensive training to your compliance, operations, and client-facing teams on the specific ECCTA Limited Partnerships reforms. Ensure they understand the new filing obligations, data requirements, and the implications of non-compliance.

7. Communicate Proactively with Clients: Begin discussions with your LP clients now. Explain the upcoming changes, the reasons behind them, and what information they will need to provide. Emphasise the importance of timely compliance to avoid penalties, which Companies House has increased powers to levy.

8. Leverage Technology for Compliance: Digital platforms can streamline the collection, verification, and filing of information, as well as maintain robust audit trails for all communications and filings. This is particularly valuable for evidencing compliance with the 'appropriate address' and ACSP filing mandates.
