UK late payment interest, worked out for you

If you sell to UK businesses, the law already lets you charge interest and compensation on late invoices. Almost nobody claims it because working it out is fiddly. Terms Due does the maths.

What the law allows

The Late Payment of Commercial Debts (Interest) Act 1998 lets a business supplier claim interest on a late business-to-business invoice at 8% a year above the Bank of England base rate, unless your contract sets a different substantial remedy.

You can also claim a fixed sum for the cost of recovering the debt, on top of the interest. Read the detail in our UK late payment interest guide.

Fixed compensation per invoice

What Terms Due does

  • Works out daily interest from the day after the due date, using the reference base rate for the right half-year.
  • Adds the correct fixed compensation for each invoice.
  • Shows interest and compensation as separate lines on the buyer's statement and final reminder.
  • Lets you waive it for any company or invoice, for example a long-standing buyer who is rarely late.

Questions

Can I charge late payment interest to consumers?

Is this legal advice?

No. Terms Due calculates the figures from your invoice dates and amounts. Check your own trade terms and take advice for disputed debts.
