For over a quarter of a century, the issue of late payments has been a persistent thorn in the side of the UK economy, particularly for small and medium-sized enterprises (SMEs). On 19 May 2026, the landscape of commercial transactions in England and Wales underwent a seismic shift with the introduction of the Commercial Payments Bill 2026 to Parliament.

This landmark legislation represents the most significant crackdown on late payments in more than 25 years. At Tyndel Solicitors, we understand that cash flow is the lifeblood of any business. Whether you are a small supplier struggling to get paid or a large corporation needing to overhaul your procurement processes, this Bill will fundamentally change how you operate.

In this comprehensive guide, we break down the key provisions of the Bill, the new powers of the Small Business Commissioner, and how our debt recovery experts can help you navigate these changes.

The 60-Day Statutory Cap: Ending the Long-Wait Culture

One of the most transformative elements of the Commercial Payments Bill 2026 is the introduction of a hard cap on payment terms. For years, large firms have leveraged their market power to impose payment terms of 90, 120, or even 180 days on smaller suppliers, effectively using them as interest-free lines of credit.

Key Provisions of the Cap:

• Private Sector (B2B): A mandatory 60-day cap on payment terms now applies to non-public authority contracts.
• Public Sector: For public authorities, the requirements are even stricter, with a maximum payment period of 30 days.
• Voiding Unlawful Terms: Any contractual clause that attempts to extend payment beyond these 60 days will be considered legally void.
• The Default Rule: Where a contract fails to specify a payment term, or where the existing term is struck out for exceeding the cap, a default 30-day payment term is automatically implied by law.

While there are limited exemptions for cross-border trade and contracts between two equally large entities, the vast majority of commercial transactions in the UK will now be governed by these strict deadlines. Businesses must review their standard terms of business immediately to ensure compliance.

Mandatory 8% Interest: No More Contracting Out

Under previous legislation, many businesses found ways to "contract out" of statutory interest or agree to "substantial remedies" that were often anything but substantial. The Commercial Payments Bill 2026 closes this loophole entirely.

The Bill mandates that statutory interest on late payments be set at 8% above the Bank of England base rate. Crucially, this is now a non-waivable right.

Why this matters:

1. Non-Negotiable: You can no longer agree to a lower interest rate in your contracts. Any attempt to do so will be void.
2. Automatic Entitlement: The interest begins to accrue the moment the 60-day (or 30-day) window closes.
3. Financial Deterrent: With base rates often fluctuating, the 8% margin provides a significant financial penalty that encourages prompt payment.

As experienced civil litigation and debt recovery specialists, we see first-hand how mandatory interest can provide the necessary leverage to settle outstanding invoices without the need for prolonged court battles.

The Small Business Commissioner: New "Teeth" for Enforcement

Perhaps the most significant change is the radical expansion of the powers granted to the Small Business Commissioner (SBC). Previously seen by some as a purely advisory body, the SBC is being transformed into a powerful regulator with the ability to impose heavy financial penalties.

Expanded Investigatory and Enforcement Powers:

• Adjudication: The SBC can now adjudicate contractual payment disputes between small and large businesses, offering a faster and cheaper alternative to the court system.
• Binding Decisions: The Commissioner has the power to make binding interim decisions, ensuring that small suppliers receive at least a portion of their funds while a dispute is being resolved.
• Turnover-Based Fines: For persistent late payers, the SBC can now levy fines of up to 1% of a business’s annual UK turnover. For major corporations, this could mean penalties in the tens of millions of pounds.
• Mandatory Investigations: The SBC can launch investigations into any large business where 25% or more of their invoices are consistently paid late.

This shift moves late payment from a private contractual issue to a regulated corporate governance matter. Larger firms must now treat their payment performance as a primary compliance risk.

New Rules for Invoice Disputes

The Bill also addresses the common tactic of raising "spurious disputes" at the last minute to delay payment. Under the new rules, a statutory deadline for disputing invoices has been established.

In most instances, a purchaser must raise any dispute regarding an invoice at least eight days before the payment falls due. Furthermore, they must provide "sufficient information" to explain the nature of the dispute.

Failure to meet this deadline or provide adequate detail triggers a fixed financial liability. The supplier becomes entitled to a fixed sum, the higher of £40 or 1% of the contract price, as a penalty for the delay. This ensures that legitimate disputes are handled early, rather than being used as a stalling tactic.

Sector-Specific Changes: Construction and Beyond

The construction industry, notorious for payment delays and "pay when paid" culture, faces specific changes. The Bill introduces a ban on construction contract retention payments, pending further consultation on the transition period. This aims to ensure that subcontractors are not left waiting years for the final 5% of their contract value.
