Estimate only — not legal advice. Applies to business-to-business and public-sector debts in the UK under the Late Payment of Commercial Debts (Interest) Act 1998 — not to consumer customers. If your contract sets a substantial alternative remedy, that replaces the statutory rate. The reference base rate is fixed for six-month periods: use the rate in force on the preceding 31 December (for debts becoming late Jan–Jun) or 30 June (Jul–Dec). Interest and compensation are outside the scope of VAT.
