Compensation for Late Payment UK Business: Your Complete Legal Guide

If you're a UK freelancer, sole trader, or small business owner, late payment from clients isn't just an inconvenience—it's a drain on your cash flow. The good news is that compensation for late payment UK business is not optional; it's a legal right. Under the Late Payment of Commercial Debts (Interest) Act 1998, you can charge statutory interest and claim fixed debt recovery costs from companies and public sector organisations that fail to pay on time.

This guide explains exactly how the law works, what you can claim, and the practical steps to recover what you're owed. We've updated all figures and rates for 2026.

What Is Late Payment Compensation Under UK Law?

Late payment compensation isn't optional. It's not something a customer can waive or negotiate away. The Late Payment of Commercial Debts (Interest) Act 1998 automatically gives you the right to charge interest on outstanding invoices after a payment deadline has been missed.

There are two main components to late payment compensation UK business owners can claim:

• Statutory interest: Automatic interest calculated on unpaid invoices
• Fixed debt recovery costs: A flat fee to cover your administration costs in chasing the debt

These rights apply to invoices issued to other businesses and public sector organisations. Consumer transactions are not covered. The compensation accrues automatically from the day the payment deadline passes—you don't need permission to charge it.

Understanding the Late Payment of Commercial Debts (Interest) Act 1998

The Late Payment of Commercial Debts (Interest) Act 1998 is the legislation that governs late payment compensation for UK business transactions. It's been strengthened several times, most recently with the Late Payment of Commercial Debts (Interest) Act 1998 (Amendment) Regulations 2015, which introduced fixed debt recovery costs.

The Act applies when:

• An invoice is issued between two businesses, or from a business to a public sector organisation
• The buyer is established in the UK
• Payment is not received by the agreed date

It does not apply to consumer sales (B2C), even if the consumer is purchasing for business use.

Key Protections for Small Businesses

The Act recognises that small businesses are particularly vulnerable to late payment. If you're a micro-enterprise (fewer than 10 employees and less than €2 million turnover), you have additional protections:

• You can claim late payment compensation even if your contract states otherwise
• Suppliers cannot legally enforce terms that attempt to remove your right to interest
• You're protected against "pay when paid" clauses that would otherwise delay your rights

Calculate Your Statutory Interest Rate for 2026

The statutory interest rate changes every six months, based on the Bank of England base rate. From 1 January 2026, the statutory interest rate is 12.50%. This is calculated as 8% plus the Bank of England base rate of 4.50%.

Here's how it works in practice:

Example: You invoice a customer for £5,000 on 1 January 2026, with payment terms of 30 days. They don't pay until 1 March 2026—60 days late.

• Unpaid amount: £5,000
• Statutory interest rate: 12.50% per annum
• Interest accrued: £5,000 × 12.50% × (60 ÷ 365) = £102.05
• Fixed debt recovery cost: £40 (for debts under £1,000) or £70 (for debts £1,000–£9,999)
• Total compensation: £5,172.05

Interest continues to accrue daily until payment is received. The longer you wait, the more compensation you can claim.

Fixed Debt Recovery Costs

In addition to statutory interest, you're entitled to claim fixed costs to cover the cost of pursuing the debt:

• Debts under £1,000: £40
• Debts £1,000–£9,999: £70
• Debts £10,000 or more: £100

These costs are fixed by law and don't need to be justified—you claim them automatically with the interest.

How to Claim Compensation for Late Payment

You have several options for claiming compensation for late payment, ranging from informal contact to legal action.

Step 1: Send a Formal Payment Demand

Start with a clear, professional letter or email. Reference:

• The original invoice number and date
• The agreed payment terms
• The date payment should have been received
• The current outstanding balance
• The statutory interest accrued to date (with your calculation)
• The fixed debt recovery costs (£40–£100)
• A final deadline for payment (usually 7–14 days)
• A statement that you'll pursue legal action if payment isn't received

Many customers will pay immediately once they realise you're aware of your rights and willing to enforce them.

Step 2: Use a Debt Recovery Service

If informal contact doesn't work, consider using a debt recovery agency. They'll handle chasing on your behalf (though they'll take a percentage of what they recover). Many reputable agencies specialise in business-to-business debt recovery and understand the Late Payment Act 1998.

Taking Action Through Small Claims Court

If compensation for late payment UK business disputes exceeds £100–£300 in disputed amounts, the Small Claims Court is your next step. The process is designed to be accessible to small business owners without legal representation.

Before You Go to Court

Most courts will expect you to have attempted alternative dispute resolution (ADR). This usually means:

• Written correspondence clearly explaining the debt
• A final deadline for payment
• Evidence of attempts to resolve the matter

Keep copies of everything—invoices, emails, payment reminders, your calculation of interest and costs.

Filing a Claim

You can file a claim through Money Claim Online (for under £100,000) or at your local county court. The filing fee depends on the amount claimed, starting from £25–£50 for small debts.

Your claim should include:

• The outstanding invoice amount
• Statutory interest calculated to the date of the claim
• Fixed debt recovery costs (£40–£100)
• The court fee
• Interest continuing to accrue at 12.50% per annum until judgment is paid

The defendant has 14 days to respond. If they don't, you can apply for a judgment by default. If they dispute the claim, a judge will review the evidence—which, for straightforward late payment cases, is usually just your invoices and proof of non-payment.

After Judgment

A court judgment is legally enforceable. If the customer still won't pay, you can apply for enforcement action, which may include:

• Bailiff intervention to recover goods
• Attachment of earnings (if an individual)
• Charging orders against property

The cost of enforcement varies, but the debtor usually has to pay these costs as well.

Preventing Late Payment in the First Place

While understanding your legal rights to compensation for late payment is essential, the best strategy is prevention.

Clear Terms and Conditions

Spell out your payment terms in every invoice and contract:

• Payment deadline: Be specific (e.g., "Payment due by 30 days from invoice date")
• Method of payment: Bank transfer, cheque, PayPal, etc.
• Late payment interest: State that statutory interest will be charged if payment is late (you can charge more if you've agreed it separately, but the statutory rate is the default)
• Your bank details: Make paying you as easy as possible

Chase Invoices Proactively

Don't wait until 60 days have passed to start chasing. Send a polite reminder at 10 days overdue, a more formal letter at 20 days overdue, and the formal demand with interest calculation at 30 days overdue.

Negotiate Better Terms with Habitual Late Payers

If a customer consistently pays late, you have options:

• Shorten payment terms (30 days instead of 60)
• Require a deposit or part-payment upfront
• Switch to invoice financing or factoring (a financial service where a lender buys your invoices for immediate cash)
• Decline future work if you can't afford the cash flow hit

Common Myths About Late Payment Compensation

Myth: "We agreed a longer payment term, so I can't charge interest."

False. You can agree extended terms (60 or 90 days), but once that deadline passes, statutory interest applies automatically. You don't need the customer's permission.

Myth: "They said they'll pay eventually, so I shouldn't chase."

False. Vague promises aren't a contract. After the agreed deadline, start accruing interest and pursue the debt formally. Interest stops when payment is received.

Myth: "Small claims court is too expensive for small debts."

False. Court fees for debts under £10,000 are modest (£25–£500 depending on the claim value). And the debtor has to pay your court fees if you win.

Myth: "Interest accrues only once per month."

False. Statutory interest accrues daily at 12.50% per annum. Every day adds to your compensation.

What About Limited Company Insolvency?

If your customer is a limited company that becomes insolvent, your claim joins other creditors. However, you still have rights:

• File a claim in the company's insolvency proceedings
• Your statutory interest claim (plus fixed debt recovery costs) has priority over unsecured creditors in some cases
• If the company has directors, explore whether director liability insurance might help recover funds

The insolvency process is complex; consider getting advice from an insolvency practitioner if the debt is substantial.

Final Thoughts: Your Right to Compensation for Late Payment

Compensation for late payment UK business law is robust and designed to protect small business owners from cash flow damage. The statutory interest rate of 12.50% (as of 2026) reflects the true cost of late payment, and fixed debt recovery costs ensure you're not out of pocket just for chasing the money that's rightfully yours.

The law is on your side. Use it. Send formal payment demands that reference statutory interest. If they don't pay, pursue the claim through Small Claims Court. Most businesses will settle rather than face judgment.

Late payment isn't inevitable. Many customers pay promptly once they realise you take your rights seriously. And for those who don't, the law gives you clear, enforceable remedies.

Your next step: Review your current outstanding invoices. Calculate how much compensation you're owed. Then take action.
