How much interest can I charge on a late invoice?

Statutory interest is 8 percentage points above the Bank of England base rate, running from the day after payment was due. At the Bank Rate of 3.75% that is 11.75% a year, which works out at roughly £0.64 a day on a £2,000 invoice. Check the current Bank Rate first, because the rate that applies is the one in force on the preceding 31 December or 30 June.

What are my payment terms if I never agreed any in writing?

The law treats the payment as late 30 days after the customer receives the invoice, or after you deliver the goods or service, whichever is later. Agreeing terms in your quote is still worth doing, because it removes the argument about which date the clock started on.

Can I charge anything on top of the interest?

Yes. You can claim fixed compensation for debt recovery costs on each late invoice: £40 for invoices up to £999.99, £70 for £1,000 to £9,999.99, and £100 for invoices of £10,000 or more. You do not need to go to court to claim it.

Does this apply to work I do for homeowners?

No. The Late Payment of Commercial Debts (Interest) Act 1998 covers business-to-business debts, so it does not apply to a homeowner paying for work on their own home. Consumer work is covered by different rules, so put your payment terms in the quote instead.

What should I do first when an invoice goes overdue?

Send a short reminder with the original invoice attached at 7 days overdue, then a formal letter before action at 21 days, and only then consider court. Keep a dated record of every message you send, because that record is what makes the later steps straightforward.

Your rights

Late Payment of Commercial Debts Act 1998

The Late Payment of Commercial Debts (Interest) Act 1998 gives you the automatic right to charge interest on late business-to-business invoices. It applies even if your contract doesn't mention it. Consumer (B2C) work is covered under different rules.

Default terms

30-day default payment terms if nothing agreed in writing

If you haven't agreed payment terms in writing, the default is 30 days from the invoice date (or delivery of goods/services, whichever is later). Always confirm terms in your quote.

Interest

Statutory interest: 8 percentage points above the Bank of England base rate

From the day after payment was due, you can charge 8 percentage points above the Bank of England's base rate (the rate set on the preceding 31 December applies for interest starting Jan–Jun, and the rate set on the preceding 30 June applies for Jul–Dec). At the Bank Rate of 3.75% (held 30 July 2026), that's 11.75% a year, or roughly £0.64/day on a £2,000 invoice. Check the current Bank Rate before you calculate, since it moves.

Compensation

Fixed late payment compensation amounts

On top of interest, you can claim fixed compensation of £40 for invoices up to £999.99, £70 for £1,000 to £9,999.99, and £100 for £10,000+. You don't need to go to court to claim these.

Step 1
