More than 1.5 million UK businesses are carrying overdue invoices

Late payment pressure is continuing to build across the UK economy.

According to R3’s latest Quarterly Business Health report, based on Creditsafe data, 1.57 million UK businesses had overdue invoices on their books in the first quarter of 2026. The total number of overdue invoices rose to 17.48 million, up 3% on the same period last year.

That is not just an accounting problem. It is a cashflow warning.

For small and medium-sized businesses, overdue invoices can quickly become a serious strain. Wages still need to be paid. Suppliers still need settling. Tax bills still arrive. Yet the money owed to the business remains locked in someone else’s bank account.

R3 president Tom Russell described late payments as an early warning sign, warning that mounting arrears can turn manageable cashflow issues into a wider crisis. That is the reality many UK businesses already understand too well.

Late payment is not harmless delay

When a customer pays late, the cost is rarely limited to the invoice itself.

Time is spent chasing. Management attention is diverted. Supplier relationships can become strained. Credit limits may be stretched. In some cases, businesses are forced to borrow simply to cover the gap created by customers who have not paid on time.

The Government has previously stated that late payments cost the UK economy £11 billion each year and contribute to the closure of 38 UK businesses every day. Those figures underline the scale of the problem, but for individual business owners the issue is much more personal.

Late payment can be the difference between confidence and uncertainty.

Construction remains under pressure

R3’s report also found that construction remained the most distressed sector in Q1 2026, with 1,159 insolvency-related cases.

That will not surprise many businesses in the sector. Construction is often exposed to long payment chains, tight margins and delayed approvals. One late payer can create pressure all the way down the supply chain.

But this is not only a construction issue. Wholesale and retail, accommodation and food services, and many other sectors are also feeling the pressure of rising costs, uncertain demand and slower payment behaviour.

Why early action matters

Overdue invoices age badly.

The longer an invoice is left unpaid, the harder it can become to recover. Payment urgency fades. Disputes are more likely to appear. The debtor may begin prioritising other creditors. In the worst cases, the customer’s financial position deteriorates before the supplier has acted.

That is why good credit control is not just about chasing debt. It is about protecting cashflow before overdue invoices become bad debts.

CPA’s guidance puts this clearly: delayed follow-up weakens payment urgency, increases dispute risk and makes repayment harder to secure. CPA helps businesses protect cashflow while preserving customer relationships.

How CPA can help

The Credit Protection Association has been helping UK businesses get paid since 1914.

Our Overdue Account Recovery service allows CPA Members to refer overdue invoices to us once their own internal process has been exhausted. We then act professionally and respectfully on the Member’s behalf, encouraging the customer to pay the Member directly.

That distinction matters. CPA does not insert itself into the customer relationship by demanding payment to us. The customer pays you, helping preserve goodwill while improving cashflow.

CPA Membership also includes CreditCare reports, monitoring alerts and other credit management tools designed to help businesses assess risk before granting credit and respond quickly when warning signs appear.

How CPA speeds up payment

CPA helps Members by adding structured, professional pressure at the right time. We contact overdue customers firmly but respectfully, making it clear that payment is expected, while keeping the relationship intact.

We are developing direct integration with leading accounting platforms such as Xero, allowing you to seamlessly refer overdue invoices to CPA instantly, without leaving your accounts package. Eliminating manual processes and administration. No duplication, no delays, just faster payment and better cashflow.

Unlike traditional debt collectors, we do not ask your customer to pay us.

They pay you, into your bank account, exactly as they would have done anyway.

That means:

• No redirection
• No disruption to your accounts
• No confusion for your customer
• No damage to your commercial relationship

Just faster payment.

How CPA gets you paid sooner

When an invoice becomes overdue, the issue is rarely inability to pay. It is priority.

CPA changes that priority.

At your instruction, we step in as a professional third party, making it clear that the account requires immediate attention. The tone remains respectful, but the message carries more weight than an internal reminder.

That shift is often enough to move your invoice from “later” to “paid”.

If you have customers who always say “we’ll get that sorted” but never quite do, this is exactly where CPA works best.

Why it works

CPA brings more than a century of credit control experience, a clear process and the authority of an established organisation. The message to the customer changes without becoming aggressive.

It says: this invoice matters, it is being monitored, and it needs to be paid.

“When should you use CPA?”

Most of our members build us into their credit management timeline.

Some pass overdue invoices to us shortly after they become due. Some use internal chases first and then pass accounts to us when those are not responded to.

But don’t leave it too long. The longer an invoice remains unpaid, the harder it becomes to recover. Early action makes all the difference.

Traditional debt collection can feel like escalation.
CPA feels like structure.

Proven results

Over 80% of accounts referred to CPA are resolved without escalation.

Most are paid within days, not weeks.

What you gain

Better cashflow. Less time spent chasing. Earlier escalation before debts go stale. A more consistent credit control process. And, importantly, a better chance of being paid without burning bridges.

Traditional debt collection often signals the end of a relationship.
CPA is designed to preserve it.
