Lawyer Explains the ‘Domino Effect’ Behind Industry Collapses
One delayed payment doesn’t stop with the business waiting to be paid. A construction dispute solicitor explains how money withheld higher up the supply chain creates a cash-flow domino effect reaching contractors, subcontractors, suppliers and the businesses relying on them.
Key Insights
- Jonathan Waters, Senior Partner and construction dispute solicitor at Helix Law, warns that construction’s interconnected supply chains mean one significant unpaid invoice creates financial pressure far beyond the business originally owed the money.
- Construction firms accounted for 17% of all insolvencies in England and Wales in July 2026, with 343 registered construction businesses becoming insolvent, despite making up 14% of all registered UK businesses as of September 2025.
- Specialised construction firms, largely subcontractors, made up the largest share, with 186 insolvencies recorded in July alone.
- The 3,841 construction insolvencies in the 12 months to July 2026 sit 19% above pre-pandemic levels, despite being down 3% year on year.
- Waters urges businesses to track total exposure rather than the oldest unpaid invoice, and to act before the position becomes critical.
How one unpaid invoice affects the supply chain
A contractor doesn’t get paid. It delays payment to a subcontractor. The subcontractor can’t pay the specialist firm it brought in. The specialist owes a materials supplier. And that supplier is already waiting on money from three other projects.
One payment problem has now travelled through an entire supply chain, and reached businesses with no connection to the original dispute.
That chain reaction is what makes late payment in construction different from late payment in most other sectors, according to Jonathan Waters, Senior Partner and construction dispute solicitor at Helix Law.
“An unpaid invoice in construction rarely exists in isolation,” says Waters. “The business waiting for £100,000 may still have wages, subcontractors, suppliers and plant costs to pay. If that money doesn’t arrive, the pressure can quickly move down the supply chain.”
The sector is absorbing that pressure unevenly. Insolvency Service figures show construction firms accounted for 17% of all insolvencies in England and Wales in July 2026, with 343 registered construction businesses becoming insolvent, 11 more than the 332 recorded in both June 2026 and July 2025. Construction made up around 14% of all registered UK businesses as of September 2025.
The weight falls furthest down the chain. Firms providing specialised construction activities, typically the subcontractors carrying out electrical, plumbing, plastering and finishing work, accounted for the largest share with 186 insolvencies in July.
Across the 12 months to July 2026, 3,841 construction firms became insolvent. That represents a 3% decrease on the 3,976 recorded in the year to July 2025, but remains 19% higher than the 3,221 in pre-pandemic 2019.
The five-business domino
Domino one: the main contractor. A stage of work is completed, and a substantial payment is expected. It doesn’t arrive on time. The contractor’s own commitments, however, have not moved.
Domino two: the subcontractor. Money owed further down the chain is delayed or disputed. The subcontractor now faces its own wages, materials, and overheads without the cash it had planned around.
Domino three: the specialist. The subcontractor brought in a specialist firm for part of the works. That invoice slips too.
Domino four: the supplier. The specialist already bought materials on credit. That bill falls due regardless of whether anyone upstream has been paid.
Domino five: an entirely separate project. This is where it stops being one job’s problem. A business under pressure starts using cash from Project B to cover the hole left by Project A. A dispute on one site is now creating exposure on another.
That sideways spread is the part businesses underestimate. The domino doesn’t travel neatly down a single chain. It moves across a company’s other jobs, other clients, and other suppliers.
Why construction most affected by unpaid invoice
Most of the money has already been spent by the time an invoice goes unpaid. Labour, materials, subcontractors, plant hire, insurance, overheads, tax, and the cost of progressing other projects are all outgoings that happen before payment arrives.
A late payment in construction isn’t a number sitting on an accounting system. The work is done, and the costs are gone.
When late payment becomes a warning sign
Waters points to a pattern of behaviours rather than any single event:
- The payment date keeps moving. Friday becomes next week, then becomes another explanation entirely.
- The reason changes. What began as an administrative delay becomes a question about quality or scope.
- Work previously signed off starts being challenged.
- Unexplained deductions appear on applications.
- Communication gets noticeably harder. Calls go unanswered, replies slow down.
- You’re asked to carry out significant further work while existing sums remain unresolved.
“No single one of those proves anything about another company’s finances,” says Waters. “But together they’re a reason to look hard at your own exposure rather than carrying on assuming the money turns up eventually. That last one in particular is the point where a lot of businesses talk themselves into continuing.”
The mistake: building exposure while you wait
A business is owed £30,000. Stopping work or escalating feels commercially uncomfortable, so it carries on. The next application falls due, and the figure becomes £60,000. Then £90,000. Meanwhile, more labour and materials have been committed against a payment that hasn’t materialised.
The available options depend heavily on the contract and the circumstances, and rights around suspension or termination need proper consideration rather than a snap decision on site. But the principle is simple: don’t let an existing payment problem quietly become a much larger one.
What to do when the first domino wobbles
- Check the contract. Understand the payment provisions, notices and deadlines that apply.
- Get clarity quickly. Ask specifically why payment hasn’t been made rather than accepting a vague reassurance.
- Document everything. Keep applications, invoices, notices, emails and messages organised and intact.
- Track total exposure. Not just the oldest unpaid invoice, but what you’ll be owed if work continues another month.
- Look downstream. Know which of your subcontractors and suppliers are depending on that payment reaching you.
- Take advice early, particularly where significant sums are disputed or another party’s financial position is a concern.
If the business above you collapses
Where a company further up the chain enters insolvency, recovering what you’re owed becomes considerably more difficult, and the options narrow.
“The time to understand how exposed you are is before the company owing you money disappears, not afterwards,” Waters says.
Ask a different question
“Construction businesses don’t operate in isolation,” Waters says. “One company failing to pay £100,000 can mean another business can’t pay its subcontractor, that subcontractor struggles to pay a supplier, and suddenly a dispute that started between two parties is affecting businesses that had nothing to do with the original problem. The earlier companies recognise that domino effect, the more opportunity they have to protect their position.”
Don’t just ask when you’ll get paid. Ask how many other businesses are relying on you getting paid.
