Late Payment Clauses: How to Protect Your Cash Flow

Late payment costs UK small businesses billions each year. The right contract clauses can deter late payers and give you powerful recovery tools.

Last updated: February 2025

Your Statutory Rights Under UK Law

The Late Payment of Commercial Debts (Interest) Act 1998 gives UK businesses automatic rights to charge interest and claim compensation on overdue B2B invoices. These rights apply even if your contract does not mention late payment, but it is far better to include explicit clauses.

  • Statutory interest rate: 8% per annum above the Bank of England base rate
  • Fixed compensation: £40 (debts under £1,000), £70 (£1,000-£9,999.99), or £100 (£10,000+)
  • These rights apply to all B2B transactions unless the contract provides a 'substantial remedy' for late payment
  • You can claim statutory interest and compensation even if the invoice has now been paid

Drafting Effective Late Payment Clauses

While statutory rights provide a baseline, contractual late payment clauses can be more comprehensive and act as a stronger deterrent. The clause should be prominent, clear, and proportionate to be enforceable.

  • Specify a contractual interest rate on overdue payments — the statutory rate of 8% plus base rate is a good starting point
  • Include a right to suspend services or deliveries if any invoice is more than 14 days overdue
  • Add a clause making the debtor liable for all reasonable recovery costs, including legal fees
  • Consider requiring a personal guarantee from directors for significant contracts with small limited companies

Practical Recovery Steps

Contract clauses are only useful if you act on them. A systematic approach to credit control reduces the need for formal recovery action and signals to clients that you take payment seriously.

  • Send a reminder 7 days before the payment is due, and on the due date if not received
  • Issue a formal late payment notice citing your contractual and statutory rights after 7 days overdue
  • For debts under £10,000, the Small Claims Court is a cost-effective recovery route
  • Consider statutory demands and winding-up petitions for larger debts from companies that can pay but will not

Key Takeaways

  • UK law gives you automatic rights to charge 8% plus base rate interest and fixed compensation on overdue B2B invoices.
  • Contractual late payment clauses should include interest, service suspension rights, and recovery cost provisions.
  • A systematic credit control process reduces late payment and makes enforcement easier when needed.

Frequently Asked Questions

Can I charge interest on late payments without a contract clause?

Yes. The Late Payment of Commercial Debts (Interest) Act 1998 gives you an automatic right to charge interest at 8% above the Bank of England base rate on any B2B invoice that is not paid by the agreed date. You can also claim fixed compensation. These are statutory rights that apply regardless of your contract terms.

How do I recover a small debt cost-effectively?

For debts under £10,000, use the Small Claims Court (now called the Small Claims Track of the County Court). The process can be started online via Money Claims Online for a small fee. You do not need a solicitor and costs are limited, making it practical for small businesses. The court fee depends on the claim value.

Can late payment clauses be challenged as unfair?

In B2B contracts, the parties have significant freedom to agree payment terms. However, under the Late Payment Act, a contractual term that tries to remove or restrict the right to statutory interest can be challenged if it does not provide a 'substantial remedy' for late payment. Excessively punitive interest rates may also be unenforceable.
