What UK small businesses should know about the Late Payment of Commercial Debts Regulations 2013
By InvoiceReminder Editorial Team · Published 6th August 2026
Cash flow is the lifeblood of any small business, and nothing disrupts it more than a client who pays late. While polite reminders are the first step, UK law provides a powerful tool to deter late payers and compensate you for the delay. This article dives deep into the Late Payment of Commercial Debts Regulations 2013, explaining how they strengthened the original 1998 Act and what rights they give your business when an invoice goes unpaid. We'll break down how to calculate statutory interest, when you can claim compensation, and how to apply these rules professionally.
The legislation might sound complex, but the rights it grants are surprisingly straightforward. Understanding them gives you the confidence to enforce your payment terms, protect your cash flow, and ensure you're compensated for the cost and inconvenience of chasing commercial debts. Let's unpack what every UK small business owner, freelancer, and accountant needs to know.
A Quick History: The Late Payment Act 1998
Before we explore the 2013 changes, it’s important to understand the foundation they were built on. The Late Payment of Commercial Debts (Interest) Act 1998 was a landmark piece of legislation for UK businesses. For the first time, it gave businesses a statutory right to charge interest on overdue commercial invoices, even if this right wasn't explicitly stated in their contract.
The goal was simple: to tackle the UK's poor payment culture, which disproportionately harms small and medium-sized enterprises (SMEs). The 1998 Act established three core principles:
- The Right to Interest: Businesses could charge interest on late payments at a rate of 8% plus the Bank of England's base rate. This is often referred to as 'statutory interest'.
- The Right to Fixed Compensation: In addition to interest, businesses could claim a fixed sum as compensation for the cost of recovering the debt. The amount depended on the size of the debt.
- An Implied Term: This right was automatically 'implied' into business-to-business (B2B) contracts, meaning you didn't need to have a clause in your terms and conditions to use it.
While a huge step forward, the 1998 Act had its limitations. The fixed compensation sums were often insufficient to cover the actual costs of debt recovery, especially if a collection agency or solicitor was required. Furthermore, payment terms in contracts could be excessively long, leaving suppliers waiting months to get paid, even if they had technically agreed to it under pressure from a larger client. These gaps set the stage for the 2013 amendments.
The Game-Changer: What Did the 2013 Regulations Actually Change?
The Late Payment of Commercial Debts Regulations 2013 were introduced to implement a new EU Directive (2011/7/EU) aimed at harmonising payment terms and strengthening the rights of creditors across Europe. While the UK has since left the EU, these regulations were transposed into UK law and remain fully in effect.
The 2013 changes didn't replace the 1998 Act; they amended and extended it. Here are the most significant changes for UK small businesses.
Change 1: Standardising Payment Terms (The 60-Day Rule)
This was arguably the most impactful change. The 2013 Regulations introduced a cap on payment periods in B2B contracts.
- For business-to-business transactions: The payment period is capped at 60 calendar days, unless a longer period is expressly agreed upon by both parties and is not 'grossly unfair' to the supplier. The default payment term, if nothing is specified in the contract, is 30 calendar days.
- For business-to-public authority transactions: The payment period is strictly capped at 30 calendar days. There is very little room for negotiation here.
Before 2013, a powerful client could impose 90- or 120-day payment terms on a small supplier, who often had little choice but to accept. The 2013 Regulations make such terms much harder to enforce. While parties can still agree to terms longer than 60 days, the burden of proof is on the customer to show this extension is not "grossly unfair". In practice, this gives suppliers a much stronger legal footing to challenge excessive payment terms.
Change 2: Extending Rights to Cover Full Recovery Costs
The 1998 Act allowed for fixed compensation of £40, £70, or £100. For a small debt, £40 might be adequate. But for a larger, more complex debt requiring significant effort to collect, it often fell short of the true cost.
The 2013 Regulations introduced a crucial addition: if the fixed compensation sum does not cover the reasonable costs of recovering the debt, the supplier has a statutory right to claim those additional costs from the debtor.
What does this mean in practice? It means you can now claim for:
- The fees charged by a debt collection agency.
- The costs of a solicitor sending a letter before action.
- Other administrative costs directly attributable to the recovery process, over and above the fixed sum.
This is a powerful deterrent. A late-paying client now knows that if they force you to escalate the matter, they could be liable not just for interest and a small fixed fee, but for the full, reasonable cost of the collection process.
Change 3: Clarifying the 'Implied Right'
The 2013 Regulations reinforced that the right to claim interest and compensation is statutory. You do not need to mention it on your invoices or in your T&Cs for it to apply. It is an automatic right for qualifying B2B transactions.
Many small businesses are hesitant to add "we reserve the right to charge interest..." to their invoices for fear of appearing aggressive. The law makes it clear that this is unnecessary. The right exists whether you state it or not.
Calculating What You're Owed: The Three-Part Formula
When an invoice becomes overdue, the total amount you can claim is made up of three distinct parts. It's crucial to calculate each part correctly.
Part 1: Statutory Interest
Statutory interest is calculated on a daily basis from the day after the invoice was due until the date it is paid.
The formula is: Debt Amount x (8% + Bank of England Base Rate) / 365
Let's break this down:
- Debt Amount: This is the total amount of the overdue invoice, including VAT if applicable.
- Bank of England Base Rate: This is the official lending rate set by the Bank of England. It can and does change. You must use the base rate that was in effect for the six-month period in which the invoice became overdue. You can always find the historic and current rates on the Bank of England's website.
- The 8%: This is the fixed statutory percentage added on top of the base rate.
Worked Example:
- You issued an invoice for £2,000 (inc. VAT).
- Payment was due on 1st March.
- The client pays you 45 days late on 15th April.
- Let's assume the Bank of England Base Rate for the period was 5.25%.
The annual interest rate you can charge is 8% + 5.25% = 13.25%.
The calculation is:
- Annual Interest: £2,000 x 13.25% = £265.00
- Daily Interest: £265.00 / 365 days = £0.726 per day
- Total Interest Owed: £0.726 x 45 days = £32.67
You can claim £32.67 in statutory interest.
Part 2: Fixed Compensation
This is a one-off charge per overdue invoice, designed to compensate you for the initial administrative effort of chasing the debt. The amount is set by law and depends on the value of the invoice (excluding VAT).
| Invoice Value (excluding VAT) | Fixed Compensation Owed |
|---|---|
| Up to £999.99 | £40 |
| £1,000 to £9,999.99 | £70 |
| £10,000 or more | £100 |
In our example above, the invoice was for £2,000. Assuming the VAT rate was 20%, the ex-VAT value is £1,666.67. This falls into the middle band, so you can claim £70 in fixed compensation.
Part 3: Reasonable Recovery Costs (The 2013 Addition)
This is the part that was added in 2013. If the £70 fixed compensation from our example did not cover your costs, you can claim the difference.
For instance, imagine that after your initial reminders were ignored, you engaged a debt collection agency that charged you a fee of £150 to recover the £2,000.
- Total reasonable recovery cost: £150
- Fixed compensation already claimed: £70
- Additional recovery costs you can claim: £150 - £70 = £80
Total amount to claim in our example:
- Statutory Interest: £32.67
- Fixed Compensation: £70.00
- Additional Recovery Costs: £80.00
- Total owed on top of original invoice: £182.67
How to Actually Apply Late Payment Charges: A Practical Guide
Knowing your rights is one thing; applying them is another. It can feel confrontational, but if handled professionally, it can be a very effective tool.
Step 1: Check Your Eligibility First, confirm the legislation applies. Is this a business-to-business transaction? The rules do not apply to invoices issued to consumers. Is there a genuine dispute over the goods or services provided? If so, the clock on late payment interest is paused until the dispute is resolved.
Step 2: Decide if You Want to Apply Charges Just because you have the right to charge interest doesn't mean you must. Consider the client relationship. For a long-standing, valuable client who has made a one-off mistake, you might choose to waive the charges as a gesture of goodwill. For a persistent late payer or a one-off client you don't expect to work with again, enforcing your rights makes commercial sense.
Step 3: Communicate Clearly and Professionally The best first step is to issue a formal statement of account. This should clearly show:
- The original invoice number and date.
- The due date.
- The number of days it is overdue.
- A line-by-line calculation of the statutory interest.
- A separate line item for the fixed compensation charge.
- A final, updated total amount due.
Send this with a polite but firm cover email explaining that as the invoice is now significantly overdue, you are exercising your statutory right to claim interest and compensation under the Late Payment of Commercial Debts Regulations 2013.
Step 4: Issue a New Invoice for the Charges Once the original debt is paid, you should issue a separate, new invoice for the interest and compensation charges. This keeps your accounting clean. A crucial point: late payment charges are not subject to VAT. Do not add VAT to this new invoice.
Step 5: Automate the Initial Chase The most effective credit control strategy is to prevent invoices from becoming seriously overdue in the first place. This is where automation can be a game-changer. Using a tool like InvoiceReminder, you can set up a schedule of automated email reminders that start as soon as an invoice is due. A typical escalation could be:
- A friendly reminder on the due date.
- A firmer follow-up 7 days later.
- A final notice 14 days later, which can mention your right to apply statutory charges if payment is not made.
Automating this process ensures consistency, saves you countless hours of manual work, and often prompts payment long before you even need to consider calculating statutory interest. It professionalises your credit control and frees you up to focus on running your business.
Frequently Asked Questions
Do I have to go to court to claim statutory interest and compensation?
No, you do not. You have the right to claim these charges directly from your debtor. The standard process is to send them a revised statement or a new invoice detailing the charges. Most businesses will pay to avoid the matter escalating further. Court action is a last resort if they refuse to pay both the original debt and the statutory charges.
Is late payment interest subject to VAT?
No. Statutory interest and compensation for late payment are considered compensation for damages, not a further supply of goods or services. Therefore, they fall outside the scope of VAT, and you should not charge VAT on them.
What is the current Bank of England base rate for late payment interest?
The Bank of England's base rate changes over time. You must use the rate that was in effect on the day the debt became overdue. The Bank of England publishes both the current and historical rates on its website. A simple search for "Bank of England base rate" will give you the current figure. Remember that for late payment purposes, the rate is fixed for a six-month period (1st Jan - 30th June and 1st July - 31st Dec).
Can I charge interest if my customer is disputing the invoice?
If there is a genuine and substantial dispute regarding the invoice (e.g., the goods were faulty or the service was not delivered as agreed), you cannot charge late payment interest for the period the dispute is ongoing. However, if the dispute is found to be spurious or a delaying tactic, the right to interest may be applied retrospectively.
Does the Late Payment Act apply to freelancers and sole traders?
Yes. The legislation applies to all "commercial debt", which covers transactions between any businesses, regardless of their legal structure. This includes sole traders, freelancers, partnerships, and limited companies. As long as you are supplying goods or services to another business (not a private individual), you are protected by the Act.
Stop Chasing, Start Getting Paid
Chasing overdue invoices is a frustrating and time-consuming drain on any business owner. While the Late Payment Regulations provide a powerful legal backstop, the best strategy is proactive credit control that stops invoices from becoming a problem. Manually tracking due dates and sending follow-up emails is inefficient and prone to error.
