Infographic - Navigating Choppy Waters: Financial Stressors for Main Contractors

The financial health of main contractors is intrinsically linked to their supply chain. 

Materials Costs: A Volatile Landscape 

The cost of construction materials has been on an upward trajectory. Over the past decade, there has been an average cost increase of 55% for construction materials in the UK (Source: UK Government). These significant and often unpredictable increases directly impact project budgets and can quickly erode profit margins, especially on fixed-price contracts. 

Subcontractor Insolvency: A Domino Effect 

The financial struggles of subcontractors can quickly cascade up the supply chain. In 2024, there were 2,514 subcontractor insolvencies in the UK (Source: UK Government). When a subcontractor goes bust, it can lead to project delays, additional costs for finding new suppliers, and most critically, the loss of retention. 

Retention Lost from Upstream Insolvency: A Costly Consequence 

Further compounding the issue of subcontractor insolvency, main contractors face the risk of losing retentions held by insolvent upstream parties. The UK Government reports that the average value of lost retention for main contractors due to upstream insolvency is a staggering £79,900. This can be a devastating blow to a contractor's finances, particularly for smaller firms. 

Working Capital: The Lifeblood of Operations 

Working capital – the difference between current assets and current liabilities – is critical for day-to-day operations. When comparing average net working capital days across sectors in Europe (2023, Source: PwC), construction stands out at an average of 83 days, compared to 73 days for manufacturing and 57 days for tech.  

Construction's high working capital days indicate that a significant amount of cash is tied up in ongoing projects, making it challenging to manage cash flow and respond to unforeseen expenses. 

Administration: Drowning in Paperwork 

Despite technological advancements, the construction industry remains highly administrative. A study by Re-flow & YouGov revealed that the average UK construction employee spends 91 hours annually on paperwork. This translates to a significant amount of unproductive time that could be better spent on core construction activities, impacting overall efficiency and profitability. 

The journey of a construction project begins with the client, and unfortunately, this is often where the first financial hurdles appear. 

Payment Cycles: The Long Wait for What's Owed 

Imagine building a house, then waiting three months to be paid for your work. For main contractors, this is a common reality. Research by GoCardless highlights the stark difference in payment terms across industries, with construction waiting an average of 90 days compared to 75 days for professional services.  

This average 90-day payment term in construction is a significant burden. It means contractors are constantly funding projects from their own capital, leading to stretched cash flow and increased reliance on financing, which in turn incurs further costs. 

Retentions: Cash Trapped in Limbo 

Beyond the long payment cycles, an additional percentage of the payment, known as retention, is typically held back by clients. In UK construction, the average retention rate stands at 5% (Source: UK Government Report – 'Retentions in the Construction Industry'). While intended as security against defects, these funds often remain unreleased long after practical completion, further restricting a contractor's working capital. 

Scope Creep: The Unforeseen Expansion 

Projects rarely stick precisely to the original plan. Unanticipated changes and additional client requests, known as "scope creep," can have a devastating impact on budgets. The Project Management Institute reports an alarming average budget overrun of 27% due to scope creep. This translates directly into unbudgeted costs and squeezed margins for contractors. 

Delays: Time is Money, and Delays Cost Both 

Construction is a time-sensitive industry, and delays are a persistent headache. Data from nPlan illustrates the prevalence of project delays in large-scale construction, with 13% of construction projects facing delays of over a year. The majority of 59% of construction projects face delays of between 60-250 days.  

With over 90% of large-scale projects experiencing delays of 60 days or more, the financial implications are enormous. Extended project timelines lead to increased labour costs, equipment rental fees, penalties, and a delay in receiving final payments. 

Rework: The Cost of Getting It Wrong 

Mistakes happen, but in construction, they can be incredibly expensive. The Get It Right Initiative estimates that the annual spend on construction rework in the UK is a staggering £10–25 billion. This includes the cost of wasted materials, additional labour, and the time lost in rectifying errors - all of which directly erode profit margins.
