An unpaid invoice becomes overdue when a customer misses the payment deadline. For businesses in England and Wales, recovering payment involves checking the contract, documenting the debt and choosing an appropriate response. A payment plan may resolve the issue, while formal recovery requires attention to evidence, costs and the customer’s ability to pay. Businesses may also have rights to interest and recovery charges on qualifying commercial debts. This article explains how to approach unpaid invoices, assess additional charges and choose between negotiation, court proceedings and enforcement.

Keeping a good business relationship can be important for repeat work, even if a client pays late. You can use strong credit control and automate reminders to save time in chasing payments.

If your debtor wants to pay but cannot pay the full amount at once, consider offering a clear, structured payment plan that outlines the: 

  • payment schedule; 
  • amounts due; and 
  • deadlines. 

This approach can help you recover your payment without resorting to formal processes, which could incur extra costs. Before you negotiate a payment plan, you should prepare to outline how you might reach a resolution.

Review the debt and determine how much is owed, and accordingly decide what you are willing to accept. Consider whether you will allow payments in stages, on longer terms, or in smaller amounts.

Legal action should usually be the last resort, after you have explored informal routes.

Acting Fast and Documenting the Debt Owed 

It is important to act quickly when an invoice is overdue, rather than waiting for things to escalate. Late payments may be due to simple human errors or delays, and a quick reminder could quickly resolve the issue. Always put any agreement you reach in writing and keep clear records and documents to help you later. 

To support a debt recovery claim, keep accurate and complete records. Whenever possible, obtain a written contract, as verbal agreements are harder to prove. To support your claim, you should retain key documents, including: 

  • unpaid invoices;
  • proof of delivery; 
  • all relevant client correspondence;
  • account statements;
  • emails; and 
  • letters about the debt.

Claiming Interest and Recovery Charges

An overdue invoice may entitle your business to recover more than the original price of goods or services. Check the contract before adding interest or recovery charges.

The Late Payment of Commercial Debts (Interest) Act 1998 allows statutory interest on qualifying commercial debts. The annual rate is eight percentage points above the applicable Bank of England base rate. However, contractual terms that provide a substantial remedy for late payment can replace that statutory entitlement. Consumer invoices do not qualify under this regime.

Understanding your right to charge interest on late payments helps you identify which terms apply before demanding an additional amount.

Where the statutory regime applies, you can also claim a fixed recovery sum for each qualifying late payment. The amounts are £40 for debts below £1,000, £70 for debts from £1,000 to £9,999.99, and £100 for larger debts. You may also recover reasonable recovery costs exceeding the fixed sum.

For example, a qualifying overdue invoice of £2,000 can attract £70 in fixed compensation, plus statutory interest. Itemise the invoice balance, interest and recovery charges separately when writing to the customer. Explain the calculation so the customer can check the total.

If you decide legal action is necessary and the debtor still does not pay after reminders and follow-up, your business may wish to issue a formal letter of claim. At this stage, your business may choose to engage a third party for support, such as a solicitor or a debt collection agency. 

Your letter of claim should hopefully prompt some action from the debtor and provide the documentation needed if recovery proceedings continue. A letter of claim is an important part of debt recovery and should be prepared carefully; legal support is advisable. You will need to provide various information, depending on whether the debtor is an individual or a business. 

Your business should specify a clear payment deadline; this is typically 14 days for businesses and 30 days for individuals. You should also explain the further consequences, including court proceedings or, where appropriate, the statutory demand route. 

Court proceedings usually come after a letter of claim. You must clearly explain the debt and the reason for your claim.

After the claim is served, the debtor has 14 days to respond or acknowledge it. If they acknowledge, the deadline to file a defence is extended to 28 days. If no defence is filed, your business can apply for judgment in default. If a defence is filed, the claim proceeds through the court process.

Enforcing a Judgment 

Once judgment is obtained, your business can choose from several enforcement options if payment is still not made.

These include: 

  • writs or warrants of control; 
  • charging orders; 
  • third-party debt orders; and 
  • attachment of earnings orders where applicable.

Your business should select the enforcement route based on the debtor’s assets and financial position.

“Winning a debt claim only solves part of the problem. I would assess the customer’s ability to pay before committing to proceedings, because a strong claim has limited commercial value without a realistic route to recovery.”

Using Statutory Demands 

Another route is a statutory demand, a formal legal notice requiring payment within 21 days.

You can issue a statutory demand against a company if the debt is over £750, or against an individual if the debt is over £5,000. If the debtor does not pay, you can commence insolvency proceedings, such as winding-up or bankruptcy.

Only use statutory demands for debts that are not disputed. If there is a dispute, follow the court process instead.

Understand Key Time Limits

Generally, your business has six years from the debt due date to issue a court claim, although few businesses wait that long in practice.

After you serve a statutory demand, the debtor has 21 days to pay. If they do not, you should start winding-up or bankruptcy proceedings promptly, usually within four months.

Understanding Your Options and Prospects 

Unpaid debts can affect cash flow and business operations. You should seek legal advice when payment issues arise to assess your recovery options and identify the best strategy. 

This guidance can help to: 

  • avoid pitfalls; 
  • preserve your leverage; and 
  • determine whether informal recovery or formal proceedings are appropriate, depending on the circumstances. 

Any escalation should be based on a careful review, considering the debt: 

  • value; 
  • enforcement prospects; and 
  • the likely time and expense.

Key Takeaways 

If you are owed unpaid invoices, you may have various legal remedies available to pursue the debtor. Before taking matters further, try to resolve the issue informally and seek advice before deciding whether formal action is worth it for your business. Debt recovery can take time, cost money, and use up management time. You will need to analyse factors such as the size of the debt, the strength of your evidence, and whether the debtor can, in fact, pay. If you do want to take legal action, a solicitor specialising in debt recovery can help you assess your options and the best way forward depending on the circumstances.

Frequently Asked Questions

Can my business agree on a payment plan instead of taking legal action against a debtor?

Yes. If the debtor cannot pay the full amount immediately, your business can agree instalments. Record the payment amounts, due dates and overall schedule in writing. Choose terms that the debtor can realistically meet and that support your business’s cash flow.

What documents should my business keep to support a debt claim?

Keep the written contract, any agreed changes, unpaid invoices, proof of delivery, account statements and correspondence about the debt. Retain emails and letters that show what the customer agreed to pay and any subsequent repayment arrangements.

What interest can I charge on an unpaid invoice?

For qualifying commercial debts, statutory interest is eight percentage points above the applicable Bank of England base rate. Check your contract first: terms providing a substantial remedy for late payment can replace statutory interest. The statutory regime does not cover consumer invoices.

Can I recover debt collection costs from the debtor?

Yes, for qualifying commercial debts, your business can claim fixed recovery costs under the Late Payment of Commercial Debts (Interest) Act 1998. Check whether the statutory regime applies to your transaction and contract before adding recovery charges.
