Why Overdue Invoices Are a Serious Problem for Tradespeople and Businesses
Late payments are more than an inconvenience—they can seriously threaten a business. For tradespeople, unpaid invoices disrupt cash flow, delay supplier payments, staff wages, and business growth. Chasing payments also wastes valuable time and energy.
To recover overdue invoices:
- Send a polite reminder as soon as the payment is overdue, including the invoice details, amount due, and payment instructions.
- Follow up with a formal overdue letter if there’s no response within 5–7 days. State the debt is overdue, set a payment deadline, mention possible statutory interest, and warn of debt recovery action.
- Call the client directly to discuss the issue, agree on a payment date, and confirm the conversation in writing to keep a clear record.
Know Your Legal Rights When Chasing Unpaid Invoices
Many business owners don’t realise UK law offers protection against late payments.
Your legal rights
The Late Payment of Commercial Debts (Interest) Act 1998 allows businesses to charge 8% above the Bank of England base rate on overdue business-to-business invoices, unless a different rate is agreed. You can also claim fixed compensation:
Debt Amount Compensation
Up to £999.99 £40
£1,000–£9,999.99 £70
£10,000+ £100
Including these charges in your payment demand can encourage faster settlement.

Frequently Asked Questions About Overdue Invoices
What is classed as an overdue invoice in the UK?
An invoice becomes overdue the day after the agreed payment date has passed. If no payment terms were agreed in advance, the default position under UK law is 30 days from the date of the invoice or the date goods or services were delivered, whichever is later.
Can I charge interest on an overdue invoice?
Yes. For business-to-business transactions, you have a statutory right to charge interest at 8% above the Bank of England base rate under the Late Payment of Commercial Debts (Interest) Act 1998. You can also claim fixed compensation of £40, £70, or £100 depending on the size of the debt.
How long should I wait before using a debt collection agency?
Most experts recommend escalating to a professional agency if payment has not been received within 30 to 60 days of the due date, particularly if the debtor has stopped communicating or made promises they have not kept.
What is the difference between Federal Management and Frontline Collections?
Federal Management specialises in recovering debts from businesses (B2B), while Frontline Collections focuses on recovering debts from private individuals (B2C). Choosing the best specialist for the type of debtor significantly improves your chances of recovery.
Will using a debt collection agency damage my relationship with the client?
It is unlikely and any risk of this can be mitigated by working with Professionals. A client who refuses to pay a legitimate invoice has already compromised any relationship. Professional debt collection agencies approach recovery in a measured and compliant manner, which mitigates the risk of unnecessary confrontation.
Can I take a debtor to court instead of using a collection agency?
It is an option however not recommended by many. You can issue a claim through the UK’s Money Claim Online (MCOL) service for debts up to £100,000.
However, court action is time-consuming, can be costly, and does not guarantee payment even if you win. Using a debt collection agency first is often faster, cheaper, and more effective.
What can I do if a client disputes the invoice?
Attempt to resolve the dispute directly and in writing first. If the dispute is genuine, consider whether a partial settlement is preferable to a prolonged dispute. If you believe the dispute is being raised in bad faith to delay payment, a debt collection agency or solicitor can help you assess your options.
