Two Years of ECCTA Name-Change Directions: How Companies House Took Back the Power to Police Misleading UK Company Names

For most of Companies House's history, its leverage over a misleading company name ended at the front door. Once a name passed the incorporation screen — clearing the prohibited list, the sensitive words rules and the same-as-another test under section 66 of the Companies Act 2006 — it was the courts, the Company Names Adjudicator, or an aggrieved competitor who had to do the policing. The registrar's own remedies, once the certificate of incorporation had issued, were narrow and slow.

The Economic Crime and Corporate Transparency Act 2023 changed the geometry. From 4 March 2024, the registrar acquired a directly enforceable power to require a company to change a name after incorporation — on grounds that would previously have required either an Adjudicator complaint, a court order, or a Secretary of State intervention. Two years on, the early data tells a clearer story than the white-paper rhetoric did: this is a real enforcement lever, not an aspirational one, and it is being used asymmetrically across categories that policymakers did not weight equally when the Bill was drafted.

The pre-ECCTA naming regime

Britain's statutory framework for company names did not lack rules — it lacked teeth. The Companies Act 2006 set out three layers of constraint at the point of incorporation:

• Prohibited names under section 53, on grounds of offensiveness or being contrary to the public interest.
• Sensitive words and expressions under sections 54–56, expanded by the Company, Limited Liability Partnership and Business (Names and Trading Disclosures) Regulations 2015. Words such as Bank, Royal, Trust, Chartered, British, Authority and Architects require either Secretary of State consent or a relevant body's letter of non-objection. The Sensitive Words and Expressions Regulations 2014 set out the comparison conventions.
• Same-as-another rules under section 66, which strip out punctuation, spacing and common suffixes when comparing names against the existing index, so that AB Holdings (UK) Ltd and A.B. Holdings UK Limited collide.

Post-incorporation, the principal remedy was the Company Names Adjudicator regime under sections 69–74 of the 2006 Act — operational since 1 October 2008 and administered by the Intellectual Property Office. A trade-mark proprietor or trading-name holder could object to a registered company name on the ground that it was an opportunistic registration aimed at exploiting goodwill. If the objection was upheld, the Adjudicator could order a change of name and award costs against the registered company.

That regime worked, within its remit. Published Adjudicator decisions show several hundred objections decided each year, the majority going to the complainant by default after the registered company filed no defence. But it was reactive, and it was private. A misleading name that did not infringe a specific complainant's trade interest — for example, one suggesting a fictitious government connection, or a string of random characters generated by an automated incorporation service — could sit on the register indefinitely.

What ECCTA actually changed

ECCTA inserted a series of new and amended provisions into Part 5 of the Companies Act 2006, giving the registrar a freestanding power to direct a name change without any complainant standing behind it. The four ECCTA grounds, broadly stated:

1. Misleading view of the nature of the company's activities — an extension of the long-dormant section 76 direction, with the bar lowered from "likely to cause harm to the public" to something closer to a reasonableness threshold.
2. False or misleading connection with a public authority, including foreign governments and overseas public authorities — closing a gap that had previously required Secretary of State intervention.
3. Names registered for a purpose connected with a criminal offence, including names used in service of fraud, money laundering or evasion of disqualification orders.
4. Names registered using false, misleading or computer-generated information, including names containing strings of characters with no apparent legitimate purpose.

A company directed to change its name is given 28 days, extendable on application, and faces criminal liability if it does not comply. If the company still fails to act, the registrar can in extremis allocate it a substitute name composed of its company number followed by Limited (or its Welsh equivalent). The substituted name is then itself protected, in the sense that the company may not adopt a replacement without registrar consent.

The procedure is not exotic. What is novel is who pulls the trigger. Before ECCTA, that decision sat with the Secretary of State for marginal misleading-activities cases and otherwise with a private complainant prepared to fund a process. Post-ECCTA it sits at Cardiff, and it sits there for free.

Volumes and patterns: the first two years

Companies House has now published several rounds of transparency data on its use of ECCTA powers. The disclosed pattern in the first 18 months is consistent: bulk action against the cheapest category (computer-generated and gibberish strings) and selective action against the more politically charged categories (false government connection, criminal-purpose names).

The clearest enforcement signal sits in the first row. Where pre-ECCTA the registrar had no straightforward way to remove the long tail of nonsense-string companies generated by automated incorporation services for use in dormancy, dissolution and money-laundering layering schemes, it now does. Companies House has confirmed in its own quarterly updates that bulk name changes are now the single largest category of post-incorporation direction, by a wide margin.

The Adjudicator's parallel docket

A reasonable prediction at ECCTA's enactment was that the Company Names Adjudicator's caseload would fall as Companies House absorbed the obvious cases. The early evidence is the opposite. Complaints to the Adjudicator have stayed steady because the trade-mark and goodwill cases the Adjudicator is designed for have always been outside ECCTA's grounds. ECCTA targets the public interest in the register; the Adjudicator vindicates private rights in a name. The two systems are now genuinely parallel rather than overlapping.

A useful way to draw the line between the four available forums:

For a small business confronting a clear cybersquatter, the Adjudicator remains the right forum: the grounds map to the wrong, and a reasoned decision is on the public file. For a regulator confronting a company calling itself British Tax Compliance Office Limited, ECCTA is now the faster route, with no need to evidence a private interest in the name.

What the data does not yet show

Three caveats merit explicit recognition.

First, the published numbers are not yet broken down by company status. Without that breakdown it is impossible to tell whether ECCTA directions are concentrated on companies that were already non-trading, already dissolved, or already linked to disqualified directors. If the directions land mainly on companies that have ceased to operate, the practical deterrent effect on live fraud is smaller than the headline volumes suggest. The transparency reports lump all directions together regardless of trading status.

Second, the substitution remedy creates its own data-quality problem. A company that fails to respond to a direction and is renamed 01234567 LIMITED is still on the register. It still has filings, charges, directors and a number. Researchers running due diligence on a counterparty by name will find nothing; those running it by company number will find a renamed shell with no narrative explanation of why the change occurred. Change-of-name history (form NM01 for company-initiated changes; a registrar-led update for ECCTA directions) is filterable in principle but not yet exposed cleanly through the Companies House public API.

Third, the Adjudicator and the registrar have not yet published a joint protocol. A complainant with both a trade-mark grievance and a public-interest concern — say, an apparent attempt to imply a connection with HMRC — has no published guidance on which door to knock on first. In practice the Adjudicator route is slower but produces a reasoned, citable decision; the ECCTA route is faster but produces a single-page direction letter that is not, in any conventional sense, precedent.

Editorial take

ECCTA's name-change powers are the least dramatic of its corporate-transparency reforms and one of the most underrated. Identity verification, the ACSP regime and the appropriate-address rule have absorbed most of the airtime in the trade press. But the names regime touches something more foundational than any of them: the integrity of how a company presents itself to the public before any filing, audit threshold, PSC declaration or director ID check is even examined.

Two years in, the registrar has acquired a power it visibly uses, and uses asymmetrically — heavily against gibberish, selectively against impersonation. The next test will be whether that power survives the political cycle. A directly enforceable, no-appeal, free-to-the-public power to compel a name change has obvious applications, and equally obvious risks if exercised against names that turn out to be unfashionable rather than unlawful. The quarterly transparency reports Companies House now publishes on its use of these directions are, quietly, doing more to underwrite the system's legitimacy than any single direction it has issued.
