UK businesses are owed an estimated £26 billion in late payments at any one time, according to government commissioned research. That is cash small firms cannot spend on hiring, equipment, training or marketing. The same research found that 10% of businesses indicated they had invested less because of late payment, and estimated that more than 14,000 firms close each year as a result. The impact of late payments on small businesses is not just a nuisance. It shrinks what they can afford to build.
The scale of the problem
| Measure | Finding |
|---|---|
| Owed at any one time | £26 billion |
| Businesses affected | More than 1.5 million, or 28% |
| Average owed per affected business | About £17,000 |
| Closures linked to late payment | More than 14,000 a year, or 38 a day |
| Jobs linked to those closures | Around 40,000 |
| Staff time spent chasing | 133 million hours a year |
| Cost to the economy | Almost £11 billion a year |
How late payment cancels growth plans
When a customer pays late, you are lending them money for free. Affected businesses in the survey gave up an average of £8,881 of investment in a year. For micro businesses, the investment forgone equalled 3.06% of turnover.
The most common casualties were plant or machinery and staff training, at around 25% each, followed by marketing at around 18%. Some firms made harder choices. The survey found businesses responding to late payment by reducing headcount, raising prices, putting in personal funds or taking on extra finance.
These are self-reported survey results, and the researchers did not find a statistically significant investment effect in their wider econometric model, so they should be read as a strong signal rather than proof of cause. But for the owner waiting on overdue invoices, the practical effect is obvious: a machine is not bought, a hire is delayed, or a campaign does not run.
The hidden cost of chasing
Businesses affected by late payment spend an average of 86 hours a year chasing money they have already earned. Across the economy, that becomes 133 million staff hours. In our experience, that time usually comes out of the same people who would otherwise be winning new work, improving systems or looking after paying customers.
In one recruitment case, recovering £21,000 of overdue invoices helped our client invest in two more recruiters. That is the point many late payers miss. An unpaid invoice is not just a line on an aged debtor report. It can be the difference between growing and standing still.
Why smaller firms feel it most
The burden falls hardest on micro businesses, where overdue invoices represent a bigger share of turnover. The government-commissioned research found that micro businesses affected by late payment had the largest relative investment impact, and construction remains especially exposed, with 10.1% of SMEs in the sector describing late payment as a big problem.
Large businesses often set the terms. Coface’s 2026 payment survey found that one third of large companies offer payment terms above 90 days, compared with 12% of micro and small firms. Our construction debt collection team sees the same pattern daily: smaller suppliers carrying the cash-flow strain while larger customers control the timetable.
Reform is coming, but it is not a reason to wait. Our guide to the Commercial Payments Bill and SME cash flow explains what could change, and the 60 day payment term problem shows why your contracts and chasing process still matter now.
What you can do before the law catches up
Late payment risk cannot be removed completely, but it can be managed earlier and more firmly.
- Run credit checking before extending terms.
- Keep aged debtors reporting current, so slippage is visible early.
- Track credit control KPIs to spot a lengthening collection period.
- Know when to escalate an invoice rather than waiting.
- Move chasing to outsourced credit control if it is eating into your week.
Not all late payment is domestic. The research found that around 16% of late payments by volume come from overseas customers, which is where our international debt collection service helps.
Frequently asked questions
How do late payments affect small businesses?
They tie up cash, force owners to fund gaps personally or borrow, eat staff time and can stop hiring, equipment purchases, marketing and training. In serious cases, they contribute to business failure.
How many UK businesses close because of late payments?
Government-commissioned research estimates that more than 14,000 businesses close each year as a result of late payment, equivalent to around 38 every day, accounting for around 40,000 jobs.
Can I charge interest on late payments?
Often, yes. Under the Late Payment of Commercial Debts (Interest) Act 1998, you can usually claim interest at 8% above the Bank of England base rate, plus fixed compensation of £40, £70 or £100 depending on the size of the debt. Our guide explains how to claim 8% statutory interest.
What is the quickest way to protect cash flow?
Check customers before you supply, chase on the first day an invoice is overdue and escalate early. Delay makes recovery harder and gives overdue invoices more time to become disputes, excuses or write-offs.
