For decades, the culture of late payments has served as a silent, debilitating anchor on the cash flow of UK small and
medium-sized enterprises (SMEs). According to recent economic impact studies, approximately 38 businesses close their doors every single day across the UK purely due to the ripple effects of delayed invoices. In a historic legislative turn, the newly introduced Small Business Protections (Late Payments) Bill, unveiled during the recent King’s Speech, aims to legally dismantle the systemic practice of larger firms using their smaller supply chains as a source of free, interest-free credit.
The draft bill introduces a series of aggressive statutory mechanisms that will fundamentally shift commercial contractual dynamics. First, it establishes a mandatory maximum payment term of 60 days for large corporations paying smaller suppliers. More importantly, it makes statutory interest—set at a punitive 8% above the Bank of England base rate—entirely non-negotiable in all commercial contracts. Larger firms will no longer be able to leverage their market dominance to force small suppliers into waiving their right to interest on late fees.
For specific sectors, most notably construction, engineering, and manufacturing, the bill goes even further: it proposes an outright ban on the practice of deducting and withholding retention payments under the terms of construction contracts. Traditionally, a percentage of cash (often 3% to 5%) is withheld from subcontractors to ensure against defects. The government’s extensive consultation confirmed that these retentions are too often lost entirely due to upstream insolvencies or bad-faith withholding.
Preparing Your Business for the Transition:
While these protections are a massive win for SME liquidity, they require structural operational shifts over the next 12 to 24 months as the bill moves through Parliament toward full implementation.
- Audit Your Accounts Receivable Protocol:
Ensure your internal invoicing systems are ready to automatically calculate and apply the 8% above-base interest rate. You must establish unambiguous documentation of the date goods or services were delivered. - Contractual Health Check:
Review standard B2B terms. If you are a larger mid-tier business, you must ensure your own payment terms do not fall foul of the new 60-day mandatory cap, as compliance reporting will face strict audit scrutiny. - Re-evaluate Contractual Assurance:
For subcontractors who have historically relied on retentions to balance project risk, start exploring alternative security mechanisms such as performance bonds or parent company guarantees.
This legislation represents a turning point for corporate responsibility. Eliminating late payments will inject critical working capital back into the engine of the economy, allowing small businesses to pivot from defensive cash preservation to proactive scaling.
