When customers delay payment: The hidden cost to businesses and what you can do about it
By Mr Bankruptcy
18th March 2026
Late or refused payments are an increasingly common challenge for UK businesses, placing unnecessary pressure on cash flow, operations, and long‑term sustainability.
For small businesses and sole traders in particular, unpaid invoices are more than an administrative headache; they can make the difference between growth and closure.
A widespread and growing problem
Studies underline how severe this issue has become. According to the Federation of Small Businesses (FSB), around 52% of UK small businesses experienced late payment in 2022.
UK businesses collectively lose billions annually in productivity and financial losses linked to chasing overdue bills.
For service providers, the consequences are immediate. Delayed payments can disrupt cash flow, making it difficult to pay staff, settle supplier invoices or buy stock.
Over time, these disruptions undermine stability, damage credit ratings, and fuel stress among business owners who have to juggle financial uncertainty with day‑to‑day operations.
Why do customers delay payment?
There are many reasons why customers might delay payment; some are unavoidable but others may be a cynical tactic:
- Cash‑flow issues of their own
- Administrative disorganisation or slow internal processes
- A dispute over the product or service delivered
- An attempt to improve their own liquidity by withholding payment
- A simple belief that they can pay when it suits them.
Regardless of the reason, the cost is carried by your business.
Your legal rights and regulations
English law provides clear protection for a business dealing with late‑paying customers:
- The Late Payment of Commercial Debts (Interest) Act 1998. This gives businesses the right to charge statutory interest at 8% plus the Bank of England base rate. You can also claim fixed‑sum compensation for late payments (£40, £70, or £100 depending on invoice value) or recover reasonable debt‑recovery costs. And unless you’ve agreed different terms in a contract, payment is legally due within 30 days for public sector bodies and 60 days for other businesses.
- The Small Business Commissioner (SBC). The SBC, established under the Enterprise Act 2016, supports small businesses in resolving payment disputes and can investigate complaints about unfair payment practices by larger firms.
- The Prompt Payment Code. This is a voluntary but influential code requiring signatories (usually large organisations) to pay their suppliers promptly and fairly. Persistent offenders risk being removed and publicly named.
Understanding your rights and the mechanisms at your disposal strengthens your position with a slow payer.
How to respond when a customer doesn’t pay
If you’re facing a late or refused payment, you can deploy several practical and legal options, escalating if necessary. Firstly:
- Send a friendly reminder. Sometimes a simple oversight is the cause and polite reminder after the due date can resolve the issue.
- Issue a formal written reminder. Restate the amount due, the original invoice reference and your payment terms. Request a firm payment date; asking the customer to commit to a specific date is better than vague promises.
- Offer a reasonable payment plan. If the customer is experiencing genuine hardship, agreeing a staged repayment plan may recover more of your money in the long run.
Maintain professional, factual communication. It’s best to avoid emotional language, keeping correspondence clear and documented but if none of these approaches get you anywhere, you may have to escalate:
- Start charging statutory interest and compensation under the Late Payment of Commercial Debts (Interest) Act.
- Send a Letter Before Action (LBA) – a formal notice giving the customer a final chance to pay before legal action.
- Use a mediation or negotiation service – this is cost‑effective and is often successful in disputes.
- Engage a debt‑collection agency; they can pursue payment on your behalf, though they will charge a fee.
- Make a claim through the Small Claims Court, for debts up to £10,000.
- Use the Money Claim Online (MCOL) service for simple, fast digital claims.
- Seek help from the Small Business Commissioner for unfair payment practices by larger clients.
As a last resort, you may have to write off a debt to prevent further recovery expense.
Protecting your business
Prevention is as important as recovery. Make sure you use clear, written contracts with unambiguous payment terms. It’s also worth running credit checks on new clients if the costs involved are significant. You can also request an upfront deposit or staged payments to reduce risk.
And make sure you invoice promptly and establish an effective reminder and tracking system (possibly automated) to avoid giving a customer any excuse for paying late.
Delayed or refused payments are a major burden on UK businesses but, by establishing robust processes and clear terms and understanding your legal rights, you can improve your chances of preventing delayed payments or, if necessary, recovering what you are owed.
