What this value means
UK statutory interest on qualifying commercial debts = Bank of England base rate + 8 percentage points (Late Payment of Commercial Debts (Interest) Act 1998; the 8pp margin is set by SI 2002/1674). The base rate is fixed for each half-year at 30 June (debts becoming late Jul-Dec) / 31 December (Jan-Jun); the Bank does not change Bank Rate on those dates, so the half-year snapshot equals the rate in force. Derived live from this API's policy-rate series.
