Phoenix Companies at Forty: Section 216 IA 1986, the ECCTA Cleanup and the Director Networks That Still Slip Through

The Insolvency Act 1986 turned forty in 2026. Most of its provisions are workhorses that practitioners cite without thought — Schedule B1 administration, Schedule 6 preferential debts, section 122 winding-up petitions. Section 216 is different. It is a slim, criminal-law gate around one specific bit of corporate misuse: directors of liquidated companies who reincorporate under the same or a similar name, draw the same customers in, and leave the same creditors holding the same losses. Britain calls the practice phoenixing, and forty years on the rules to police it remain — in formal terms — almost untouched.

What has changed in 2026 is the surrounding architecture. The Economic Crime and Corporate Transparency Act 2023 (ECCTA) gave Companies House a new toolkit: directions to change misleading names under section 1100B of the Companies Act 2006, identity verification for every director, sharper grounds to refuse incorporation, and a registrar empowered to query and reject filings rather than nod them through. Director ID, mandatory for new appointments since April 2026 and in transition for the existing register until April 2027, should in principle pull phoenix patterns into daylight. In practice, the Insolvency Service's section 216 prosecution numbers have not visibly shifted. The criminal regime is forty years old; the data infrastructure that could feed it is six months old; and the two have yet to meet.

This piece walks through what section 216 actually prohibits, the three exceptions practitioners rely on, how phoenixing now intersects with ECCTA's enforcement layer, and what the Companies House register can and cannot currently surface.

What section 216 actually prohibits

Section 216 of the Insolvency Act 1986 makes it a criminal offence — and grounds for personal liability — for someone who was a director (or shadow director) of a company in the twelve months before it entered insolvent liquidation to be, for the following five years, any of the following without permission:

• A director of any other company known by a prohibited name
• Concerned in the promotion, formation or management of any other company so named
• Concerned in carrying on any business carried on otherwise than by a company under a prohibited name

A prohibited name is defined in section 216(2) as a name by which the liquidated company was known at any point in the twelve months before liquidation, or one so similar to that name as to suggest an association with it.

The so-similar test is doing most of the work in practice. The leading authority — Ricketts v Ad Valorem Factors Ltd [2003] EWCA Civ 1706 — adopted the test of whether the names, considered in their relevant context, would suggest an association in the mind of a person familiar with the failed company. Adding "(2024) Ltd", swapping "Limited" for "(UK) Ltd", or merely rearranging the words rarely creates enough distance.

Breach is punishable by up to two years' imprisonment, an unlimited fine, or both. Section 217 then layers civil personal liability on top: the offending director is jointly and severally liable for the new company's debts incurred while they were involved in its management, alongside anyone who knowingly acted on their instructions.

The three exceptions that swallow the rule

The Insolvency (England and Wales) Rules 2016 carve out three exceptions, in rules 22.4 to 22.7, that are widely used and reasonably well-documented in practice:

Rule 22.4 — the IP-led sale — is the route that overlaps most heavily with the pre-pack administration regime. A pre-pack sale to connected parties triggers the Pre-Pack Pool referral under SI 2021/427, but the section 216 carve-out is a separate test, sitting on top of — not within — the administration order. The two regimes have grown up alongside each other and remain awkwardly bolted together.

Rule 22.7 is the quietest of the three, and the one most often overlooked in casework. It works only where the new vehicle has a clean twelve-month trading history in its own right; off-the-shelf companies activated days before liquidation do not qualify, and the rule's wording rules out shells that were dormant during the relevant period.

What the Companies House register shows — and doesn't

A central oddity of the section 216 regime is that none of its enforcement currency is filed at Companies House in any structured form. There is no "permission obtained" form, no checkbox on an IN01 incorporation to declare that the proposed name was previously used by an insolvent associate, and no field on a CS01 confirmation statement to disclose past directorships of liquidated companies. The register simply does not ask.

Three filings carry the signal indirectly:

1. NM01 name-change resolutions — a phoenix successor sometimes changes its name shortly after the predecessor enters liquidation, either to comply with section 216 by abandoning the prohibited name, or to drift just far enough from the original to mount a defence. NM01 filings clustered in the four weeks following an insolvency announcement are a well-known investigative tell.
2. AP01 director appointments — for the new company, these record the directors taking the wheel. Cross-referenced against TM01 director terminations on the liquidated company in the same window, a phoenix overlap becomes visible. Companies House does not surface these joins; commercial director-network platforms increasingly do.
3. Court orders for permission to use a prohibited name — when granted under section 216(3), these are advertised in the London Gazette, the Edinburgh Gazette or the Belfast Gazette depending on jurisdiction. The Gazettes remain the canonical source for the genuinely lawful phoenix transaction; the absence of a Gazette notice is the most common evidential gap in section 217 personal-liability litigation.

The result is a regime built on the assumption that the Insolvency Service, creditors, and commercial intelligence providers will do the matching work themselves. Companies House supplies the raw filings; section 216 enforcement happens elsewhere.

ECCTA and the registrar's new powers — partial overlap, no merger

ECCTA's name-change architecture, under section 1100B of the Companies Act 2006, gives the registrar a power to direct a company to change a name that is misleading, that could give a false impression of the company's activities, or that has been used for a purpose connected with fraud. The power is administrative and civil; it does not require Insolvency Service involvement.

In principle, ECCTA closes part of the phoenix gap. A successor company whose name signals continuity with a liquidated predecessor — and which is trading on misappropriated goodwill — is exactly the kind of vehicle Companies House can now direct to rename, irrespective of whether the directors involved have committed a section 216 offence. In practice, the registrar's new power and the section 216 criminal regime are not formally joined up: a name-change direction is not, by itself, evidence of a section 216 breach, and a successful section 216 prosecution does not automatically trigger registrar action against any associated entity.

The table below sets out where the three current enforcement layers sit alongside one another:

A determined phoenix abuser can, in theory, face all three regimes for the same conduct. The Insolvency Service's published enforcement figures suggest the overlap is rare in practice: CDDA disqualification undertakings still account for the vast majority of director-misconduct outcomes, with section 216 prosecutions a small minority and discrete section 1100B directions, in this first full year of operation, lower still.

Director networks and the data that does not yet flow

ECCTA's most consequential structural change for phoenix detection is not section 1100B but the mandatory director identity verification regime now extending across the existing register. For the first time, a single verified person identifier — not a name string — sits behind every appointment.

In theory, that identifier should let the Insolvency Service join the dots on a director's full appointment history, including liquidated predecessors, with no fuzzy name-matching required. In practice three frictions remain:

1. The verified-person identifier is held by Companies House but is not yet exposed as a public field in the Companies House API. Director-network products that already do this matching rely on name-and-date-of-birth heuristics, which Companies House has been progressively obscuring as part of the personal information suppression regime introduced by ECCTA.
2. The Insolvency Service's case-management systems and Companies House's filings index remain on separate technical estates. Cross-referencing requires a manual data-share request, not a live query.
3. Section 216 has never been a high-volume offence to enforce, and Insolvency Service resourcing has tracked that. Better data, on its own, does not translate into more prosecutions without a corresponding shift in enforcement priorities.

The most likely first-order effect of director ID is therefore not a surge in section 216 prosecutions, but cleaner data for the commercial providers and creditors who currently do the bulk of phoenix detection — and a less hospitable environment for the most casual reusers, who have historically relied on name variations and the absence of a single director index to escape notice.

What changes next

Without legislative change, two operational shifts would do most of the remaining work. The first is tighter scrutiny of connected-party sales that fall outside the rule 22.4 carve-out: the IP-led sale is the rule designed to launder a phoenix transition lawfully, and the test for whether a particular sale qualifies sits with the practitioner, not the registrar. The second is pattern-matching against directors who appoint themselves to multiple post-liquidation vehicles in close succession, something director ID now makes technically straightforward and that previously depended on commercial datasets to do well.

ECCTA section 1100B will continue to take the visible cases — names so close to insolvent predecessors that the registrar can act on the public face of the filings alone. The harder cases, where directors disperse across new vehicles under unrelated names, will continue to depend on commercial director-network mapping and creditor-driven section 217 actions.

Forty years on, the section 216 architecture has weathered well. The bigger question for 2026 is whether the data layer underneath it — identity-verified, registrar-curated, increasingly machine-readable — can finally feed it at the volume the original drafters of the Insolvency Act 1986 might have hoped.
