Can I Claim Debt Recovery Costs on a Late Payment? Yes — Here's Exactly How

What Does the Late Payment Act Actually Say?

The Late Payment of Commercial Debts (Interest) Act 1998 (amended in 2002 to align with EU Directive 2000/35/EC) does something unusually powerful: it implies statutory rights into every commercial contract, whether or not either party ever thought about late payment terms.

That means if you have a business-to-business contract and the customer pays late, you are legally entitled to claim — full stop. You don't need to have agreed it upfront. You don't need to have sent a specific warning letter first. The right exists automatically.

It covers:

• Contracts between two businesses
• Contracts between businesses and public authorities
• All sectors — freelancers, agencies, manufacturers, consultants, trades

It does not cover: B2C transactions (selling to consumers), employment contracts, or financial services regulated separately.

When Does a Payment Become "Late"?

A payment is legally late when it passes the agreed payment date in your contract. If no date was agreed, the default under the Act is 30 days after:

• The date the customer received the invoice, or
• The date goods or services were delivered (whichever is later)

You can agree a longer payment term — up to 60 days for most commercial contracts. Beyond 60 days is only enforceable if both parties explicitly agreed it in writing and it is not grossly unfair to the supplier. Terms of 90 or 120 days imposed unilaterally by large buyers are challengeable under the Act.

Practical note: The clock starts from the date the invoice is received, not sent. If you're emailing invoices, keep delivery receipts or use tracked sending. It matters if you ever go to court.

The Three Things You Can Claim

1. Fixed Compensation (Per Invoice)

This is the simplest entitlement — a flat fee per late invoice, regardless of how long it's been outstanding:

• £40 — for invoices under £1,000
• £70 — for invoices between £1,000 and £9,999.99
• £100 — for invoices of £10,000 or more

This applies per invoice, not per debtor. If a client has 10 overdue invoices each worth £2,000, you can claim £700 in fixed compensation alone — on top of the principal debt.

2. Statutory Interest

You can charge interest at 8% per annum above the Bank of England base rate, calculated on a daily basis from the date payment became late.

As of April 2026, with the BoE base rate at 4.5%, the statutory interest rate is 12.5% per annum — or roughly 0.034% per day.

3. Reasonable Debt Recovery Costs

If you've had to spend money recovering the debt — beyond the fixed compensation — you can claim those costs too. What counts as "reasonable":

• Solicitor or debt collection agency fees
• Court filing fees (if you pursue a County Court Judgment)
• Credit reporting or tracing fees
• Time spent by a specialist credit controller (if you can evidence this)

The key word is reasonable. You cannot claim your own internal admin time as a general rule, but you can claim costs that are proportionate to the debt size and demonstrably incurred in recovery.

How to Actually Add These Charges to an Invoice or Demand Letter

There's no magic formula, but here's a structure that's clear, legally grounded, and harder to dispute:

Send by email and recorded post if the debt is significant. The paper trail matters if you escalate to court.

What If the Debtor Refuses to Pay the Additional Charges?

This happens. Common responses from late payers:

"We didn't agree to late payment charges."

They don't need to. The Act implies these rights automatically. No contract clause, no prior agreement, no warning letter required. If they want to dispute it, they'll need to show the charges are "unreasonable" or that a different contractual term applies — which is a high bar.

"Our standard terms say 60-day payment."

If you signed their terms, the 60-day period may be valid. But interest and fixed compensation still apply from day 61. And if those terms were never properly incorporated into your contract, they may not apply at all.

"We'll pay the invoice but not the interest."

You can accept partial payment without waiving your right to the additional amounts — as long as you make it clear in writing that you're accepting the payment "on account" and that the balance remains due. A sentence in your acknowledgement email is enough.

Escalating to Court

For debts under £10,000, the Small Claims Court (online at gov.uk) is fast, cheap, and doesn't require a solicitor. Filing fees start at £35 for claims under £300, scaling to £455 for claims up to £10,000. Court fees are recoverable if you win.

For larger debts, the County Court or a commercial debt collection agency is appropriate. Many agencies work on a contingency basis — no recovery, no fee.

Can You Contract Out of the Late Payment Act?

A customer cannot simply put a clause in their terms that removes your statutory rights. Any attempt to do so is void unless the substitute payment terms are deemed "substantial contractual remedy" — meaning they provide an equivalent or better remedy for late payment.

Courts have been skeptical of clauses that try to remove statutory rights without replacing them with something genuinely fair. If in doubt, the Act's protections still apply.

Does Invoice Size or Business Size Matter?

No. The Act applies whether you're a sole trader with a £300 invoice or a mid-market firm chasing £300,000. There's no minimum turnover, no minimum invoice value, no sector restriction.

In practice, many smaller businesses hesitate to add late payment charges to avoid damaging a client relationship. That's understandable — but it's worth knowing the right exists. Even just referencing the Act in your payment terms and reminder emails often accelerates payment without any confrontation.

Best Practices: Build This Into Your Process, Not Just Your Disputes

The businesses that get paid fastest aren't the ones who threaten legal action — they're the ones who make late payment consequences visible before the invoice is ever due.

• State your rights in your payment terms: "Invoices unpaid after [X] days are subject to interest and fixed compensation under the Late Payment of Commercial Debts (Interest) Act 1998."
• Send a reminder before the due date: A friendly nudge at day -3 prevents most lateness. It also establishes a paper trail if you do need to escalate.
• Issue the late payment notice on day 1 of lateness: Don't wait two weeks. The moment it's overdue, send the formal notice with the statutory amounts calculated.
• Use automation: Manually tracking 50 invoices across 30 clients is how things slip. Tools that flag overdue invoices and send escalating chasers automatically remove the emotional friction of chasing money.

Frequently Asked Questions

Can I claim debt recovery costs on late payment without a solicitor?

Yes. For debts under £10,000, the Small Claims Court process is designed to be used without legal representation. You file online at gov.uk, pay a filing fee (from £35), and the court handles the process. A solicitor is only necessary for complex disputes or larger debts where legal strategy matters.

Does claiming late payment interest damage client relationships?

It depends on how you do it. Embedding your statutory rights into your standard terms and sending professional, automated reminders is very different from an aggressive phone call. Most clients who receive a clear, factual notice referencing the Act simply pay — they know the law is on your side. For genuine long-term clients, a conversation before formal action is always worth having.

What if I'm based in Scotland or Northern Ireland?

The Late Payment of Commercial Debts (Interest) Act 1998 applies across the UK, including Scotland and Northern Ireland. The rights are the same. The court process for enforcing unpaid debts differs slightly (Sheriff Court in Scotland, County Court in Northern Ireland), but the underlying entitlements are identical.
