For UK accountants + audit firms onboarding corporate clients
Phoenix director detection at client onboarding
A phoenix pattern at Companies House — a director repeatedly incorporating, accruing trading liabilities, then dissolving and re-incorporating in the same trade — is one of the strongest fraud signals an accountant can spot at client onboarding. MLR-2017 reg 33 enhanced due diligence triggers fire on the pattern, and the Insolvency Service operates a dedicated Phoenixing Hotline for reports under the Company Directors Disqualification Act 1986. The Stratum Business Risk + Director Score API surfaces the pattern in its director-cross-link analysis.
The three signals to watch
First: officer-history clustering — a single individual appears as director or PSC across 3+ dissolved companies with overlapping tenure inside a 36-month window. Second: registered-office reuse — consecutive companies share a registered office, especially a residential one (formation-agent addresses are normal, residential is a near-certain flag). Third: SIC + trading-name continuity — the new company files the same primary SIC code as its dissolved predecessors, often with a single-word name change (Acme Builders → Acme Building → Acme Build). Two-of-three triggers MLR-2017 enhanced due diligence; three-of-three is a phoenix pattern with high confidence.
How to surface the signal at onboarding
Pull the prospective client's Companies House profile (B-CH-1) and walk the director list. For each director, query /v1/business-risk/{ch-number}/director-cross-exposure with the director's officer ID. The response returns every UK company the director has ever been appointed to, with status (active / dissolved / liquidation / strike-off) and dissolution-date if applicable. A director with 3+ dissolved companies in the trailing 36 months at shared SIC codes triggers the phoenix flag. The pattern stays in the client-acceptance memo as documented enhanced-due-diligence ground.
What to do once the pattern fires
The accountant's options under MLR-2017 reg 33 + the firm's risk-acceptance policy: (a) refuse the engagement and document the rationale; (b) accept with documented enhanced ongoing monitoring (re-screen every 6 months minimum); (c) refer to the firm's MLRO for an EDD review before commitment. Accepting without documentation is the worst option — at HMRC inspection, an unflagged phoenix-pattern director on the client roster is a near-certain finding. The Stratum suite cert PDF stamps the phoenix-flag query into the audit trail so the firm can evidence the check at inspection.
Frequently asked
Is a single dissolved company a phoenix flag?
No. UK businesses dissolve for many legitimate reasons (founder retirement, business closure, group restructuring). The pattern requires 3+ dissolutions in 36 months at shared SIC codes, with overlapping director tenure across the dissolved companies. A single dissolution is not a flag on its own.
What about creditors' voluntary liquidation specifically?
CVL is a stronger signal than strike-off because it implies creditor-loss at dissolution — the typical phoenix mechanism. The API surfaces dissolution mode as a separate field; weight CVL more heavily than strike-off in the firm's risk model.
Does the API include the Director Disqualification Register?
Yes — the response cross-references the Insolvency Service disqualified-directors register and flags any officer with active or historic disqualification. A disqualified director currently appearing as a PSC is itself a separate flag (reg 5 UBO concerns).
Is this enough on its own for client acceptance?
No. The phoenix flag is one input to the firm's wider risk assessment. Pair with sanctions / PEP / adverse-media screening on the named individuals (use the suite endpoint) and source-of-funds verification where MLR-2017 enhanced due diligence triggers fire.
How does this compare to Creditsafe + Endole?
Creditsafe + Endole sell deeper financial enrichment (10-year accounts, credit limit recommendations, trade-payment data). Stratum surfaces the director-cross-link pattern at per-call pricing without requiring a subscription. For a firm running 50-200 onboarding checks per year, the per-call model is materially cheaper than a Creditsafe annual contract.
