Under the Late Payment of Commercial Debts (Interest) Act 1998, statutory interest is 8% plus the Bank of England base rate set on the relevant reference date. Fixed compensation is £40 for debts under £1,000, £70 for £1,000 to £9,999.99, and £100 for £10,000 or more. Enter the base rate that applied — this tool does not look it up.
