Late payment has long been a major issue across the construction industry – particularly for small and medium-sized businesses and subcontractors – often creating significant pressure on cash flow and overall financial stability.

That is why the government’s proposed Small Business Protections Bill is attracting significant attention across the sector. The Bill, which entered Parliament today (19th May), is being described as the biggest crackdown on late payments in more than 25 years. Keep reading this week’s blog to find out more about what the proposed changes involve and what this means for construction and the wider economy.

Why late payment matters in construction

Construction is heavily reliant on subcontractors and specialist trades, many of which are small or medium-sized businesses operating within complex supply chains.

When payments are delayed at any point in the chain, the impact can quickly spread across multiple organisations. Businesses may struggle to manage wages, materials, supplier costs and day-to-day operations, even when projects themselves are progressing successfully. In some cases, businesses may be carrying out work correctly and on time, only to wait months before receiving payment.

In a sector already facing wider challenges around costs, labour availability and market uncertainty, improving payment practices is increasingly seen as an important part of creating a healthier and more sustainable industry.

What is the Small Business Protections Bill?

The proposed legislation, introduced to Parliament on 19th May, is intended to strengthen protections for small businesses and self-employed people by tackling unfair payment practices.

Key measures include:

  • A clear 60-day cap on payment terms on all large firms paying smaller suppliers.
  • Mandatory interest on late payments, set at 8% above the Bank of England base rate.
  • A ban on the practice of withholding retention payments under construction contracts.  

In addition, the Small Business Commissioner will receive significant new powers to investigate poor payment practices, adjudicate disputes and fine the worst offenders.

The overall aim is to create a fairer environment where smaller businesses are not left carrying disproportionate financial risk while waiting for payments to arrive.

Minister for Small Business and Economic Transformation, Blair McDougall said:

“I’ve spoken to too many business owners who do everything right and are still left lying awake at night wondering how they’ll pay their staff or cover their bills because they haven’t been paid what they’re owed.

“Introducing this Bill is about standing up for those people, to restore fairness, dignity and security for small business owners and the self-employed, so they can focus on doing what they do best: growing their businesses and the economy.”

What could this mean for the construction sector?

For construction businesses, stronger payment protections could have several positive implications.

More reliable payment practices can help improve cash flow stability, giving businesses greater confidence when planning workloads, investing in staff and managing supplier relationships.

The proposed changes may also encourage greater transparency and accountability across supply chains, helping reinforce good commercial practices throughout the industry. For many businesses, this is not simply a financial issue – it is about creating greater stability, supporting long-term growth and giving smaller companies more confidence and security.

However, as with any major legislative change, the success of the Bill will ultimately depend on how effectively the measures are implemented and enforced in practice.

Final thoughts

Late payment remains one of the most significant challenges facing many small businesses across construction and beyond. The proposed Small Business Protections Bill represents an attempt to address some of these long-standing issues and improve confidence across supply chains.

While the long-term impact of the legislation will depend on how it is delivered in practice, the focus on fairer payment practices is likely to be welcomed by many businesses across the sector.
