How confident are you in your supply chain risk strategy? The hidden risk of National Minimum Wage Breaches

Working with suppliers who breach National Minimum Wage (NMW) law can expose your business to significant reputational and financial risks. Recently, the UK government’s naming scheme publicly identified over 500 employers1 for underpaying workers, highlighting a widespread issue. For main contractors, this isn’t just a distant problem; it represents a direct supply chain risk. A supplier’s non-compliance can compromise your Environmental, Social, and Governance (ESG) commitments, damage your reputation, and jeopardise your prospects in competitive tenders. Ensuring ethical labour practices throughout your supply chain is crucial.

  • Why suppliers breach the rules 
  • The consequences for businesses that breach National Minimum Wage law

What is the National Minimum Wage in the UK?

The National Minimum Wage (NMW) is the minimum hourly pay that most workers are legally entitled to receive. The rate depends on a worker’s age and whether they are an apprentice. For those aged 21 and over, this is known as the National Living Wage (NLW).

Rates are reviewed annually by the government. As of April 20262, the rates are: 

  • £12.71 per hour for workers aged 21 and over (National Living Wage) 
  • £10.85 per hour for workers aged 18-20 
  • £8 per hour for workers under 18 and apprentices 

It is the employer’s legal responsibility to ensure all workers receive the correct pay. This includes correctly calculating working hours, accounting for different types of work, and making only legally permitted deductions.

 

Why do suppliers breach National Minimum Wage regulations? 

Breaches of National Minimum Wage regulations can happen for several reasons, ranging from accidental errors to deliberate avoidance. Ignorance of the law is not considered an acceptable defence by HM Revenue and Customs (HMRC), the body responsible for enforcement. 

Common causes for underpayment include: 

  • Incorrect calculation of working hours: Failing to pay for all time worked, including overtime, travel time between assignments, or training. 
  • Improper deductions: Deductions for items such as uniforms, tools, or accommodation that reduce a worker’s pay below the National Minimum Wage. 
  • Misunderstanding regulations: Errors in accounting for specific work types, such as sleep-in shifts or piece work, can lead to underpayment. 
  • Failure to apply annual rate increases: Not updating payroll systems when the National Minimum Wage rates change each April. 

Whether accidental or intentional, HMRC investigates all reported cases of wage underpayment, and the consequences for non-compliant employers are severe.

 

Consequences for subcontractors who fail to pay the National Minimum Wage 

Subcontractors/Suppliers who fail to meet their National Minimum Wage obligations face a range of serious penalties3 that can impact their financial stability and market standing. 

  • Financial Penalties: Employers can be fined up to 200% of the arrears owed to workers, capped at £20,000 per underpaid worker. They must also repay all the money owed to their employees. 
  • Public Naming: The government operates a ‘naming and shaming’ scheme, publicly identifying non-compliant employers. This public disclosure can cause immense reputational damage. For instance, recent naming rounds have included companies within the construction supply chain, tarnishing their brand and business relationships. 
  • Legal Action: In the most serious cases, employers can face criminal prosecution under the National Minimum Wage Act 1998. 
  • Reputational Damage: Being publicly named as a business that underpays its workers can destroy trust with customers, partners, and potential clients, making it difficult to secure future work. 

 

Is this ethical labour? Meeting your Social Value obligations 

National Minimum Wage compliance is a cornerstone of ethical labour practices. When you engage with your supply chain, you are also taking on a responsibility to uphold social value. The Social Value Act encourages public sector buyers to consider how their procurement might improve the economic, social, and environmental well-being of an area. 

Working with suppliers who breach National Minimum Wage law directly undermines this. It means your projects may rely on labour practices that fail to meet expected employment standards, contributing to unfair competition and an erosion of employment standards. For public sector contracts, demonstrating ethical supply chain management is increasingly a requirement, and a failure to do so can lead to disqualification. Your ESG strategy is only as strong as the weakest link in your supply chain.

The fallout from a supplier’s National Minimum Wage breach extends far beyond their own business, creating direct risks for your projects and company. 

  • Reputational Risk: Your brand becomes associated with your supplier’s poor employment practices. This can lead to negative press and public backlash, regardless of your direct involvement. 
  • Tender Disqualification: You risk being excluded from public and private sector contracts that demand proof of an ethical and compliant supply chain. 
  • Project Disruption: A supplier facing significant HMRC fines and enforcement action may become financially unstable, leading to delays, disruption, or even their complete failure, leaving you to find a replacement mid-project. 
  • Due Diligence Failures: It demonstrates a lack of oversight in your supply chain management, raising questions for investors, clients, and regulators about your risk management processes. 
  • Stakeholder Pressure: Modern investors, customers, and employees expect and demand that companies operate ethically. A failure to ensure this can damage stakeholder confidence.
