The UK government has introduced new legislation aimed at speeding up payments between businesses, in a move designed to reduce long-standing delays that affect suppliers across the retail and wider commercial sector.

The Bill, now before Parliament, is being described by ministers as the most significant intervention on late payments in more than two decades.

Late payments have been a recurring problem in UK retail supply chains, where smaller suppliers often wait weeks or months to be paid by larger buyers. The government says the reforms are intended to improve cash flow, reduce financial pressure on smaller firms, and make payment practices more transparent across the economy.

Payment rules

The proposed law sets out tighter expectations on how quickly businesses must settle invoices. It is expected to strengthen maximum payment terms and improve how companies handle invoice approvals and disputes.

Larger firms will come under greater scrutiny, particularly around how consistently they pay suppliers. The government also plans to increase transparency so that suppliers can better assess the payment behaviour of potential customers before entering contracts.

Ministers have said the aim is to create “faster and fairer payment practices” across supply chains, reducing the uncertainty many smaller firms currently face when waiting for payments.

Retail supply chains

Retail businesses are among those most exposed to late payment practices, particularly smaller suppliers that depend on steady cash flow to manage stock, staffing, and operating costs.

Industry concerns have long focused on how delayed payments can quickly create knock-on effects. Even when sales are strong, late invoices can force businesses to rely on short-term borrowing or delay their own payments to suppliers.

The government’s reforms are intended to reduce these pressures by encouraging faster settlement of invoices and clearer timelines for resolving payment disputes. For international retailers operating in the UK, the changes may also affect contract terms and supplier management practices.

Enforcement

A key part of the Bill is stronger enforcement of payment standards. Larger companies will be expected to provide clearer reporting on their payment performance, making it easier for regulators and business partners to track behaviour over time.

The government has indicated that non-compliance will face tougher oversight, although detailed mechanisms will be set out as the legislation progresses through Parliament.

Overall, the policy marks a shift towards tighter regulation of commercial payment practices in the UK. If fully implemented, it is expected to improve liquidity for small suppliers and bring greater predictability to retail and industrial supply chains.
