Over half of manufacturing suppliers report receiving late payments from customers, with an average invoice taking nearly two months to settle. The UK government's research estimates that late payments cost the UK economy almost £11 billion a year, affecting over 1.5 million businesses, with £26 billion owed at any one time and around 14,000 firms closing each year as a direct result.
Late payment pressures intensified for businesses in the first quarter of 2026, with the number of overdue invoices rising to 17.48 million, up 3% on the same period last year, while 1.57 million UK businesses had overdue bills on their books. Almost two-thirds of invoices UK small businesses sent in the past year were paid late, based on millions of invoices from over 200,000 FreeAgent customers. For small and medium-sized enterprises, this situation has become a systemic threat leading to cash flow crises and operational inefficiencies.
Even a single late payment can force a manufacturer to delay their own purchases and slow production; when this happens at scale, the ripple effects disrupt the entire supply chain, both upstream and downstream. Late payments severely impact suppliers that lack the financial cushion to weather cash flow crises effectively; SMEs frequently resort to unfavourable credit options such as high-interest loans or lines of credit, and this financial strain can force drastic measures including reduced investments, staff cuts, and delayed payments to their own suppliers, all of which can quickly snowball across their supply chain.
Large firms will be required to pay smaller suppliers within 60 days, with late payments subject to mandatory interest of 8% above Bank of England base rate. The new measures also give the Small Business Commissioner powers to investigate businesses suspected of conducting poor payment practices and adjudicate disputes between businesses, as well as the ability to fine persistent late-paying businesses. These measures, announced in March 2026 and confirmed in the King's Speech in May, represent what is being called the toughest laws on late payments in the G7.
