Contractor Vetting for Other Services — UK Guide

PSC ownership concentration averaging 13.4 risk score across 241,013 records reveals a pattern of concentrated control masked by structural complexity. In the Other Services sector—where contractors often operate with minimal capital and high failure rates—concentrated ownership frequently obscures beneficial interests of disqualified individuals, sanctions targets, or undisclosed third parties. When one PSC controls >75% of a company yet has minimal documented involvement, or when PSC information is incomplete, it indicates deliberate obfuscation. This directly threatens your business: hidden controllers may misappropriate funds, lack genuine financial commitment, or expose you to reputational risk through hidden associations. For contractors managing client premises access, sensitive data, or vulnerable individuals, ownership transparency is non-negotiable.

The sector average of 1.4 directors with 250,033 flagged records establishes a baseline: one or two directors is normal. Multiple directors—particularly four or more—warrants investigation. Ask: Why are there so many? Are all actively involved? Many multi-director arrangements reflect nominee structures where passive investors hold directorships while hidden PSCs exercise control. Request a written explanation of each director's role. Cross-check director names against other company directorships: individuals holding directorships across 10+ companies, particularly in similar service sectors, often function as professional nominees. This opacity makes accountability difficult if disputes arise. Verify each director independently through credit checks and Companies House disqualification searches.

Prioritise three areas: cash position, liabilities, and trend trajectory. Contractors with negative working capital, current liabilities exceeding current assets, or declining turnover year-on-year represent acute insolvency risk. Calculate cash conversion: if accounts show £500k revenue but minimal cash, investigate why. Request recent bank statements—published accounts are historical. Look for qualified auditor opinions ('except for' or 'adverse') indicating accounting problems. Compare payment history: contractors with long payment cycles often indicate cash flow stress. For contracts extending >6 months, request quarterly management accounts, not just annual filings. A contractor showing deteriorating figures may collapse mid-contract, leaving you liable for service gaps and potential redundancy obligations if workers are engaged.

Annual vetting is minimum; quarterly for high-value relationships or safety-sensitive services. With 129,145 new companies forming since 2020 and 0.3% sector dissolution rate, the landscape shifts constantly. Implement automated monitoring: subscribe to Companies House alerts for your contractors' filing changes, director updates, and account submissions. When a contractor updates their PSC register, changes directors, or files late accounts, this warrants immediate investigation. For security, cleaning, or event contractors accessing sensitive areas, conduct re-checks every six months. The cost (typically £50-200 per contractor per check) is minimal compared to risks: a single contractor failure causing service disruption, liability claims, or compliance breaches easily costs £10k+ in disruption and legal fees. Treat vetting as ongoing risk management, not one-time compliance.

Don't ignore findings; address immediately and document your actions. If vetting reveals disqualified directors, undisclosed sanctions exposure, or financial collapse indicators, termination is appropriate—many contracts include right to terminate for compliance failures. Contact your legal counsel before proceeding. If risks are moderate (late accounts filing, director changes), implement conditional engagement: increased monitoring, shorter contract terms, performance bonds, or reduced access to sensitive areas pending resolution. Request the contractor to remediate findings—updated PSC disclosures, financial explanations, insurance proof. Document all correspondence. If you continue despite known risks, you face regulatory liability claiming inadequate due diligence if subsequent problems arise. For existing relationships, vetting failure is an opportunity to reset terms: renegotiate with risk-reflective pricing or escalated oversight. Never assume previous vetting is ongoing.
