How We Turned a Subcontractor Insolvency into a £340,000 Recovery
The Call
It was 8am on a Monday morning. The MD's voice told me everything before he'd finished his first sentence.
His key mechanical subcontractor had entered liquidation overnight. Eight weeks from Practical Completion. The project was a significant commercial development. The mechanical package was substantial, partially defective in places he couldn't yet fully quantify, and now sitting in the hands of an insolvency practitioner whose primary obligation was to creditors, not to him.
"We're in big trouble, aren't we?"
I understood why he thought so. The instinctive read of subcontractor insolvency is catastrophic: programme collapse, emergency procurement costs, lost margin, client penalties and a debt that will never be recovered because the company it's owed by no longer meaningfully exists.
That instinct is wrong. And the gap between that instinct and the correct commercial response is worth, in this case, £340,000.
The Total Loss Myth
The construction industry has a deeply embedded and deeply damaging relationship with subcontractor insolvency. It treats it as an act of God - an unpredictable external force against which the only sensible response is to absorb the loss, recover what scraps the administrator throws your way, and get the project finished as cheaply as possible.
This framing is almost entirely incorrect, and it costs main contractors significant recoverable money on a regular basis.
Insolvency is not an act of God. It is a contractual trigger event. It engages defined legal remedies, bond provisions, set-off rights and debt recovery mechanisms that are already written into your contract. The money does not simply evaporate because a subcontractor enters administration or liquidation. What happens is that the legal mechanisms for recovery become active, and the contractors who recover well are the ones who understand those mechanisms, have the documentation to deploy them, and move with the speed the situation demands.
The contractors who write it off as a loss are the ones who didn't build the foundation before the crisis, don't know what bond they hold or whether it's properly executed, can't accurately articulate the overpayment position and haven't got a forensic schedule of outstanding works to hand.
In short, they lose money that was theoretically recoverable because they weren't ready to recover it.
The UK Construction Insolvency Landscape
Before getting into the mechanics of recovery, it is worth being clear about the operating environment. UK construction has the highest insolvency rate of any sector in the economy, and has held that position for years. The combination of thin margins, long payment chains, demanding procurement practices, inflationary cost pressures and complex subcontract structures creates conditions in which subcontractor insolvency is not an exceptional event - it is a recurring feature of the industry's commercial landscape.
The practical implication is straightforward: the question is not whether a subcontractor on your supply chain will enter insolvency. The question is when, and whether you will be ready when it happens.
Every main contractor running a significant programme of projects carries latent insolvency exposure at any given moment. The businesses that manage this well treat it as a systemic risk to be managed proactively, not a random shock to be absorbed reactively.
The Legal Architecture You Need to Understand
To execute a recovery of this kind, you need to understand the legal framework you are operating within - because your rights are defined by it, and the speed at which you act within it determines how much you recover.
Termination provisions. Under most standard form subcontracts - JCT, NEC and their bespoke equivalents - insolvency of the subcontractor is a specified ground for termination by the main contractor. This matters because it defines your rights on termination: the ability to engage a replacement contractor, to set off costs against sums otherwise due and to draw on any performance security. You do not need to wait for the administrator to tell you what is happening. The contractual trigger is insolvency itself.
Performance bonds. If your subcontract includes a performance bond - and for any significant package it should - this is a critical asset that is routinely underused or misunderstood. There are two fundamentally different types, and the distinction is commercially decisive.
An on-demand bond (sometimes called an unconditional bond) is payable on demand, without the need to prove loss. The bond holder presents the demand, the surety pays. These are the most commercially powerful form of security, and precisely because of that, sureties and subcontractors resist them.
A default bond (or conditional bond) requires you to demonstrate a breach of contract and quantify your loss before the surety is obliged to pay. This is the more common form in UK construction subcontracting, and it requires proper evidencing and claim preparation to call effectively.
If you don't know which type you hold - or whether you hold a validly executed bond at all - you cannot call it. The bond sitting in a filing cabinet somewhere, unsigned, undated or with incorrect party details, is worthless.
Set-off rights. Both at common law and under most standard form contracts, you have the right to set off sums properly due to the subcontractor against sums owed by them to you - whether for overpayment, defects, or costs of completion. Under the Housing Grants, Construction and Regeneration Act 1996, a valid pay less notice must be issued if you intend to deduct sums otherwise due, but insolvency does not remove your underlying set-off rights. Speed and precision in issuing the correct contractual notices is essential.
The insolvency practitioner's position. Administrators and liquidators are officers of the court acting in the interests of creditors. They will not volunteer information about your entitlements, they will not chase you to call your bond and they are not your commercial partner. They are a counterparty with their own objectives. Treat them as such. Engage quickly, establish your secured and unsecured positions clearly, and do not assume that cooperative communication means they are acting in your interest.
The Three Recovery Streams
We didn't chase one pot of money. We pursued three simultaneously, and the speed with which we moved across all three was central to the result.
Stream One: The Insolvency Debt - £127,000
The starting point in any subcontractor insolvency is an accurate, defensible reconciliation of what has been paid against what has been installed and completed. This is the payment versus value analysis, and it defines your secured and unsecured positions.
In this case, we had precise, contemporaneous records of every valuation, payment and application. We knew the exact overpayment position before the administrator's first communication. We immediately applied contractual set-off against unpaid valuations and retention that had not yet been released, securing £127,000 before it left our account.
The critical word here is "before." Once money leaves your account and sits in an insolvent estate, your claim is unsecured. You join a creditor queue. You may recover pennies in the pound, or nothing. Set-off exercised before payment is protected. Set-off claimed after payment is largely academic.
This is why the "value vs payment tracker" - an accurate, live reconciliation of payment against installed value - is not an administrative nicety. It is a financial protection mechanism. If you are systematically overpaying your subcontractors relative to the value installed, you are carrying unsecured credit exposure on your balance sheet whether you know it or not.
Stream Two: The Defect Claim - £89,000
Performance bonds cover more than insolvency. They cover performance - meaning they can be called in respect of defective work that constitutes a breach of contract, regardless of whether insolvency has occurred.
In this case, a rapid and thorough inspection of the completed mechanical works identified £89,000 of defective installation. Some of it had been concealed. All of it was evidenced by independent inspection reports prepared specifically for the bond claim.
The bond claim was not simply "the subcontractor has gone bust." It was a precisely documented breach of contract claim, supported by independent expert evidence, quantified to a specific sum and presented in a format that the surety could assess without needing to conduct its own investigation to understand the loss.
Sureties, like any commercial entity, are looking for reasons to reduce or resist payment. Your job is to remove those reasons by making the claim undeniable. A vague assertion of defects does not achieve that. A schedule of defects supported by photographs, inspection reports and cost evidence does.
Stream Three: Completion Funding - £124,000
The bond company funded the replacement contractor directly. They accepted liability promptly - not because they were generous, but because our evidence package gave them no commercially rational basis for delay, and because paying quickly reduced their exposure to the costs of programme delay.
The scoping of outstanding works was complete before we engaged replacement contractors. We knew exactly what was unfinished, exactly what was defective and exactly what the replacement contractor would be pricing. That precision eliminated the "risk premium" that replacement contractors almost always build into emergency pricing when they cannot define the scope of what they're taking on.
The completion costs were funded from the bond. The programme was maintained. Practical Completion was achieved on time.
The Insolvency Defence Framework
The recovery described above was possible because the groundwork had been laid. None of the three streams were available to us by luck. They were available because the right documentation, the right contracts and the right tracking systems were in place before the crisis hit.
The Bond Audit. Do you physically hold the signed performance bond for each significant subcontract package? Is it properly executed - signed by the correct parties, dated, with the surety's details accurate? Is it an on-demand or default bond, and do you understand the precise trigger conditions? If you cannot answer those questions in under two minutes, you are carrying bond protection that you may not actually be able to call.
The Value vs Payment Tracker. For every significant subcontractor, do you know - today, not at month end - the precise relationship between what has been paid and what has been installed? If you are overpaid relative to installed value, you are unsecured for the difference. That exposure crystallises immediately upon insolvency. This is not a sophisticated management information requirement - it is a basic commercial hygiene standard.
The Scope Gap. The single largest cost driver in subcontractor insolvency is the scoping gap - the premium that replacement contractors build into emergency pricing because they cannot establish precisely what is outstanding. A forensic schedule of remaining works, updated at each valuation cycle, eliminates that premium. It turns an emergency procurement into a defined scope appointment. The difference in pricing is significant.
Notice Readiness. Do you know the contractual notices required to formally terminate under your subcontract and to call the bond? Are the notice provisions clearly understood - service method, addressee, timing? Incorrect or late notices can compromise your legal position materially. This is not a situation for improvisation.
The Broader Lesson
The MD's question at 8am - "We're in big trouble, aren't we?" - is asked by contractors every week across the UK. Most of the time, the answer is more nuanced than they assume. Sometimes, the honest answer is that the trouble is real and significant, but still manageable if the right actions are taken immediately. Occasionally, as in this case, the answer is that with the right preparation and the right response, what looks like a crisis is actually a recoverable commercial event.
The difference between a £340,000 recovery and a £500,000 loss in this scenario was not cleverness under fire. It was preparation before the fire started. The documentation was accurate. The bond was properly held and understood. The notices were ready. The scope was defined.
Insolvency is rising across the UK construction supply chain. The economic conditions driving it - thin margins, cost inflation, payment chain pressure, interest rate sensitivity - have not meaningfully reversed. If you are running a significant contracting business and you have not stress-tested your insolvency exposure across your key supply chain, you are making an assumption about the future that the industry's history does not support.
The question is not whether a subcontractor in your supply chain will enter insolvency. The question is whether you will be ready to recover when one does.
If You're Worried About a Shaky Subcontractor
If you have a subcontractor you're watching nervously, or if you want to build the documentation systems and contractual framework that turn a potential insolvency event into a managed recovery rather than a write-off, I can help. I can review your exposure across your supply chain and prepare the Insolvency Defence Pack that ensures you are ready to claim, not just absorb.
