What is an overdue payment — what it means and what to do in the UK

What is an overdue payment and what it means for you in the UK

An overdue payment is simply any payment not made by the date set in a contract, account statement or credit agreement. What follows – phone calls, late fees, interest, a record on your credit file or even court action – depends on whether the debt is consumer credit (like a loan or credit card), a business invoice, and the contract and regulatory rules that apply.

Read on to understand the immediate consequences, the differences between consumer and commercial debts under UK rules, and sensible next steps whether you are the payer or the person chasing money.

What typically happens after a missed consumer payment

If you miss a consumer payment, most firms will contact you with reminders and warnings and may apply charges or interest permitted by the contract. Lenders and other regulated firms must follow the Financial Conduct Authority's rules on treating customers fairly and on communications about missed payments, including considering vulnerability when deciding forbearance or payment plans; see the FCA policy on deferred payment credit for the regulatory context.Financial Conduct Authority guidance

A missed consumer payment is often recorded as an arrears entry with credit reference agencies. That entry can make it harder or more expensive to borrow in future. For practical consumer steps and what to expect if a creditor takes things further, Citizens Advice explains the court process and the importance of responding to any claim.Guidance from Citizens Advice

Why this matters: consumer-credit outcomes are not uniform. There is no single statutory “late fee” that applies to all consumer credit; the contract and FCA rules determine what a firm may lawfully charge and how it must communicate.

How commercial (B2B) overdue payments differ — statutory interest and compensation

For business-to-business invoices the law gives suppliers clearer, statutory remedies. Under the Late Payment of Commercial Debts (Interest) Act 1998 a supplier of qualifying commercial goods or services may charge statutory interest and claim fixed compensation for debt recovery costs; the government explains how to calculate and recover these sums.Charging interest on late commercial payments (GOV.UK) The Act itself sets the legal entitlement to interest for qualifying commercial debts.Late Payment of Commercial Debts (Interest) Act 1998

A practical example: if a small business issues a 30‑day invoice and the buyer pays after that term, the supplier can normally add statutory interest and a small fixed compensation amount without needing a separate contractual clause. That statutory entitlement does not automatically apply to consumer purchases — it is aimed at commercial transactions.

When unpaid debts can lead to court and enforcement

If informal contact and reminders fail, a creditor may start court action. In England and Wales, a successful claim can lead to a county court judgment (CCJ). A CCJ appears on the Register of Judgments, Orders and Fines and can remain for six years, affecting creditworthiness and enabling enforcement options such as attachment of earnings or bailiffs. For an overview of CCJs and what they mean, see GOV.UK's guidance on county court judgments for debt.County court judgments for debt (GOV.UK)

If a judgment is obtained but not paid, the courts provide tools a creditor can use to enforce payment; HM Courts & Tribunals Service sets out practical post-judgment options and consequences.What to do if a defendant does not pay money after judgment (EX321)

Note: procedures and remedies can differ in Scotland and Northern Ireland. If jurisdiction matters to your case, check the relevant local procedures.

Practical steps if you have an overdue payment (as the payer)

1. Check the agreement and whether the debt is regulated. If the payment relates to regulated consumer credit, the FCA rules affect what the firm may charge and the forbearance you can request.Financial Conduct Authority guidance

2. Contact the lender or supplier immediately. Explain your situation, ask for a temporary payment plan or hardship arrangement, and request written confirmation of any revised terms.

3. Keep records. Save statements, emails, and notes of calls. If you dispute the amount, use the provider’s complaints process and hold evidence (invoices, delivery records, bank statements) that supports your position.

4. Respond to court documents. If you receive a claim form do not ignore it — failing to respond can lead to a default judgment. Citizens Advice explains how to respond and the risks of not replying.Citizens Advice on being taken to court for debt

5. Get specialist advice if enforcement begins. Enforcement action or insolvency risk are moments to seek legal or regulated debt-advice help.

Practical caveat: asking for time or disputing a charge does not erase an underlying contractual obligation. However, early, clear communication often prevents escalation.

Practical steps if you're chasing an overdue payment (as the creditor)

1. Start with clear, polite contact and a statement of the invoice, due date and outstanding sum. Attach evidence of supply where relevant.

2. For business invoices, consider calculating statutory interest and compensation under the Late Payment of Commercial Debts (Interest) Act 1998; official guidance explains the calculation and recovery process.Charging interest on late commercial payments (GOV.UK) and the statutory provision is at legislation.gov.uk.

3. If informal steps fail, a formal written demand can clarify your position and signal readiness to litigate. Before sending formal documents, some businesses use services that prepare professional demand letters from the paperwork they provide; a practical option is to review those documents carefully and keep any demand factual and proportionate. For an example provider that prepares dispute documents from customer-provided information, see BeforeSuit.

4. If you issue court proceedings, follow the rules for the relevant UK jurisdiction and be aware a judgment is no guarantee of recovery — post-judgment enforcement has costs and limits. For guidance on what enforcement options the courts provide after judgment, see the HMCTS material.What to do if a defendant does not pay money after judgment (EX321)

How to decide your next move

If the sum is small and the payer admits the debt but cannot pay, a realistic payment plan is often the quickest, cheapest solution. If the payer disputes the invoice, gather documents and follow the supplier’s complaint process; if you are the supplier, keep correspondence factual and time-stamped. If litigation is a live possibility, weigh the cost, time and likelihood of recovery against the amount at stake.

Where rules are complex or enforcement is threatened, get regulated legal or debt-advice help — especially when court papers arrive or enforcement action begins.

There is no one automatic consequence for an overdue payment in the UK: the outcome depends on the contract, whether the debt is consumer or commercial, regulatory rules and, ultimately, whether court proceedings are started. Use the official guidance and regulator material cited above to check specific rights and procedures before deciding your next step.
