The late payment is a symptom.
The contract clause is the cause.

About the Late Payment of Commercial Debts Act 1998

UK law entitles businesses to claim statutory interest on late B2B payments at 8% above the Bank of England base rate, plus fixed compensation of £40 (debts under £1,000), £70 (£1,000–£9,999.99), or £100 (£10,000+). Interest runs from the day after the payment due date. This applies automatically — you don't need a late payment clause in your contract to claim it, but having one makes it easier to enforce.
