Construction Insolvencies: A Structural Problem, not a Sudden Shock

The UK construction sector has now recorded the highest number of insolvencies for the fourth consecutive year.

This is no longer a short-term correction.It is a sustained trend.

Construction is one of the UK’s largest employers and supports thousands of small and medium-sized businesses across specialist trades and subcontracting disciplines.

When insolvency levels remain elevated for this length of time, it suggests deeper structural pressures rather than isolated mismanagement.

So what is driving it?

‍

Margin Compression‍

For many subcontractors, margins have been tight for years. Rising labour costs, material inflation and energy prices have not always been recoverable under fixed-price contracts. In competitive environments where work is won by tender, pricing discipline is often sacrificed to secure pipeline. The result is often that the contact won may generate turnover, but there is little resilience.

Cashflow Misalignment

Construction businesses frequently operate on extended payment terms, often with retention clauses that can delay payment and part of the contract value.  This creates a structural funding gap.  Profitability on paper does not equate to liquidity in the bank.  When debtor days extend beyond agreed terms,the working capital burden shifts entirely onto the subcontractor.

‍

Interconnected Risk

The sector is highly interconnected.  When a main contractor fails, the impact travels quickly through the supply chain. One unpaid contract can destabilise multiple smaller firms, particularly where there is limited cash buffer.

Tighter HMRC Enforcement

During the pandemic, enforcement was understandably relaxed.  That environment has changed.  Time to Pay arrangements are more closely monitored, arrears escalate more quickly, and HMRC is once again an active petitioner in winding-up proceedings. For businesses already operating with thin liquidity, this accelerates distress.

Overtrading
In a number of cases,insolvency follows a period of growth. Increased turnover without strengthened financial controls or additional working capital can heighten exposure rather than reduce it. Expansion funded by supplier credit or delayed tax liabilities is inherently fragile.

Importantly, most construction insolvencies are not caused by a lack of skill or effort. They are frequently the product of cumulative pressure: thin margins, delayed receipts, rising costs and late intervention.

What does this mean in practice?

It means directors in the sector need greater visibility over:

• Break-even turnover and contribution margins
• Contract-level profitability
• Cashflow forecasting, not just historic accounts
• Exposure to single large contracts or counter parties
• Tax liabilities building outside formal arrangements

For advisers, it reinforces the importance of early engagement. Once statutory demands or winding-up petitions (Court applications to close a company) are issued, options narrow significantly.

At Certus, we are seeing a continued flow of construction-related appointments across specialist trades and subcontractors.  The common thread is rarely misconduct.  More often, it is structural cash strain combined with delayed decision-making.

The current insolvency data suggests that this is unlikely to be a short-lived spike.  It is a sector operating under sustained pressure.

For accountants, lawyers and financial advisers working with construction clients, ongoing monitoring of liquidity and contract risk is becoming as important as year-end profitability.
