The Turbulence Report: Carillion — £7 Billion in Debt, £29 Million in Cash, and 30,000 Suppliers Who Got Nothing

The Quote That Aged Like Milk in a Heatwave

In August 2016, Carillion published its half-year report. The language was the kind of warm, reassuring corporate prose that credit departments love to see:

The annual report echoed it: "The Group continues to be well positioned to make further progress."

If you were a supplier reading those words — a subcontractor deciding whether to extend payment terms, a materials company wondering whether to take on a £500,000 exposure — you'd have felt reassured. The UK's second-largest construction company, running 450 government contracts, staffing 18,000 people. Well positioned.

Eleven months later, Carillion announced an £845 million impairment charge. The share price fell 39% in a single day. Seventy percent in three days.

Five months after that, on 15 January 2018, the company entered compulsory liquidation. It had £7 billion in liabilities and £29 million in cash. That's enough cash to cover roughly 0.4% of what it owed.

Thirty thousand suppliers found out what "well positioned" actually meant.

What the FCA Found — February 2026

This isn't ancient history. In February 2026, the Financial Conduct Authority published its Final Notice on Carillion's former CEO, Richard Howson. The ruling is extraordinary in its directness.

The FCA found that Howson "acted recklessly" in making statements to the market. He knew about serious financial deterioration and failed to ensure Carillion's public announcements reflected reality. The Insolvency Service went further, finding that Howson had published "misleading" market announcements and that the company's accounting "falsified and concealed" its actual position.

The fine: £237,700. A fraction of the damage inflicted on 30,000 suppliers, 18,000 employees, and the UK taxpayer who inherited the cost of 450 orphaned government contracts.

Howson was banned from UK directorships for eight years. He moved to Florida and became president of an American company whose own CEO, as it happens, is a convicted felon. You couldn't script it.

Seven Years Later: Still Nothing

In September 2025, PwC's administration report — seven full years after the collapse — revealed that 60 of 84 Carillion group companies cannot pay unsecured creditors a single penny. Only 23 subsidiaries have any realistic prospect of distributing anything at all.

For the suppliers who extended credit, delivered materials, poured concrete, and laid cable for Carillion projects in 2016 and 2017, the balance owed is as close to £0.00 recovery as mathematics allows without reaching it.

The pension deficit: £1 billion. KPMG, Carillion's auditor from 2013 to 2017, was fined £21 million for what the Financial Reporting Council called "exceptional" audit failures. The finance directors received bans of 11 to 12.5 years.

What Every Supplier Should Have Seen

Carillion's warning signs were visible to anyone who looked past the annual report's language. The company was using aggressive revenue recognition, running unsustainable payment terms with its supply chain, and carrying pension obligations it could never meet. The operating margins were thin. The cash conversion was poor. The debt was climbing while the order book was front-loaded with low-margin work.

But the annual report said "well positioned." And most credit departments stopped reading there.

This is the fundamental problem with corporate due diligence as practised by most businesses: they read the headline, not the footnote. They check the credit rating, not the cash flow. They see a household name and assume household names don't default.

Carillion was a household name. It defaulted. And it didn't just default — it evaporated, taking £7 billion in supplier obligations with it.

The Debtor Passport Would Have Caught This

Every warning sign Carillion exhibited maps directly to the checkpoints in the Debtor Passport framework. Registration gaps, financial deterioration, communication patterns that prioritised reassurance over substance, payment behaviour that was stretching long before the public disclosure.

Your construction debtor doesn't need to be Carillion-sized to leave you with nothing. The warning signs are the same at every scale. A £50,000 default uses the same playbook as a £7 billion one — the debtor reassures, delays, and then disappears.

The only difference is the number of zeros.

The Intercol Position

We've recovered construction sector debts across 14 jurisdictions. The pattern is always the same: by the time the supplier contacts us, they've already sent four reminders, made two phone calls, and received one vague promise. The debtor isn't going to pay because you asked nicely a fifth time.

If a customer's payment behaviour has changed — even slightly — the countdown has started.
