Understanding late payments

Late payments are one of the biggest challenges facing small businesses in the UK. Knowing what counts as a late payment, and how it affects your finances, helps you take the right action early.

A payment becomes late when it isn't received by the agreed due date on your invoice. If you haven't set specific payment terms, the default under UK law is 30 days from either the delivery of goods or services, or the date the customer receives the invoice.

According to gov.uk guidance on late commercial payments, businesses have the right to claim interest and compensation when payments are overdue. Despite these protections, late payments remain widespread across the UK.

The knock-on effects can be severe. When customers don't pay on time, your own cash flow suffers. You may struggle to pay your suppliers, cover wages, or invest in growth. For many small businesses, even a single overdue invoice can create a chain reaction of financial problems.

Why minimising late payments matters

Reducing late payments isn't just about getting paid faster. It's about keeping your business healthy and your relationships strong.

When invoices go unpaid, you may miss your own financial obligations. Rent, supplier bills, and tax payments don't wait for your customers to settle up. Falling behind on these can lead to penalties, damaged credit ratings, and strained relationships with your own suppliers.

Late payments also limit your ability to grow. Money tied up in unpaid invoices can't be reinvested in stock, equipment, or hiring. This puts you at a disadvantage compared to competitors who get paid on time.

Beyond the financial impact, chasing overdue payments takes time and energy. It creates stress and distracts you from running your business. Strong payment practices free you up to focus on what you do best.

Your legal rights when payments are late

UK law gives you clear rights when a commercial customer pays late. The Late Payment of Commercial Debts (Interest) Act 1998 sets out what you can charge, and recent reforms are strengthening these protections further.

Charging interest on late commercial payments

You don't need to accept late payments without compensation. The law allows you to charge statutory interest on overdue commercial debts.

The statutory interest rate is 8% per year above the Bank of England base rate. With the base rate currently at 3.75%, that gives a total rate of 11.75% per year.

Here's how that works in practice. On a £1,000 debt, the annual interest at 11.75% comes to £117.50 per year, or about 32p per day. After 30 days, that adds up to approximately £9.66 in interest on top of the original amount owed.

Claiming debt recovery costs

On top of interest, you can claim a fixed sum to cover the cost of recovering each overdue payment. The amount depends on the size of the debt.

• £40 for debts up to £999.99.
• £70 for debts between £1,000 and £9,999.99.
• £100 for debts of £10,000 or more.

These amounts apply per invoice, not per client. So if a customer has 3 overdue invoices, you can claim the fixed recovery cost on each one separately.

New UK late payment reforms

The UK government announced significant reforms in March 2026 to tackle late payments more aggressively. These changes represent the strongest crackdown on late payments in over 25 years.

The key reforms include:

• A maximum 60-day payment term for large firms paying smaller suppliers.
• Mandatory statutory interest clauses in all commercial contracts.
• Greater enforcement powers for the Small Business Commissioner.
• Financial penalties for businesses that persistently pay late.

You can read the full details of these reforms in the government's announcement on late payment reforms.

Common causes of late payments

Understanding why payments arrive late helps you prevent the problem before it starts. Here are the most common reasons businesses face overdue invoices.

Inconsistent invoicing practices

If you don't invoice regularly or on time, your customers won't pay regularly or on time either. Delays in sending invoices push back the entire payment cycle. A consistent invoicing schedule keeps payments predictable.

Unclear payment terms

Vague or missing payment terms leave room for misunderstanding. If your customer doesn't know exactly when payment is due, how to pay, or what happens if they're late, delays become more likely. Spelling out your terms upfront removes ambiguity.

Not following up on your invoice

Sometimes invoices simply get lost, overlooked, or deprioritised. Without a follow-up process, overdue payments can drift for weeks. A simple reminder system can make a big difference to how quickly you get paid.

Financial difficulties

Your customer may be dealing with their own cash flow problems. They might intend to pay but lack the funds to do so on time. Offering flexible payment options, such as staged payments, can help in these situations.

Disputes over goods or services

If a customer isn't satisfied with what they've received, they may withhold payment until the issue is resolved. Clear contracts, accurate descriptions, and prompt communication can reduce the risk of disputes delaying your payments.

How to reduce late payments

You can take practical steps to manage late payments and protect your cash flow. Here are the most effective strategies to get paid on time.

Assess payment risk before taking on clients

A little due diligence upfront can save you significant trouble later. Check a potential client's payment track record before you agree to work with them.

• Run a credit check to assess their financial health.
• Ask for trade references from other suppliers.
• Look up their company details on Companies House.
• Consider requesting a deposit or staged payments for larger projects.

Make your payment terms super clear

Your invoice payment terms should leave no room for confusion. Include them in your contracts, quotes, and invoices so your customer sees them at every stage.

Your terms should cover:

• A specific payment deadline, for example, 14 or 30 days from the invoice date.
• Accepted payment methods.
• Late payment fees and interest charges.
• Your refund or returns policy.
• Any early payment discounts you offer.

Write accurate, complete invoices

An invoice with errors or missing information gives your customer a reason to delay payment. Getting the details right the first time speeds up the whole process.

Use this checklist every time you send an invoice:

• Correctly identify the payee and their billing address.
• Include a specific due date, not just "due on receipt."
• Match the payment terms to what you've agreed in your contract.
• Add the correct purchase order number if your client requires one.
• Send the invoice as soon as the work is complete or goods are delivered.
• Itemise each product or service with a clear description.
• State your accepted payment methods.

Invoice promptly and professionally

The sooner you send your invoice, the sooner the payment clock starts ticking. Delays in invoicing translate directly into delays in payment.

Set up a regular invoicing schedule so nothing slips through the cracks. Use professional invoice templates to save time and maintain a consistent, polished look. Automating your invoicing process removes the manual effort and reduces the chance of errors.

Follow up on late payments

A structured follow-up process helps you chase outstanding invoices without damaging client relationships. Start politely and escalate gradually.

• Send a friendly reminder on the day the payment becomes overdue.
• Follow up with a phone call after one week if there's still no response.
• Issue a final notice stating the amount owed, any accrued interest, and the consequences of continued non-payment.

Build strong client relationships

Clients who value your relationship are more likely to pay on time. Regular communication, reliable service, and a professional approach all contribute to a healthy working dynamic.

Make it easy for clients to raise concerns early. If they're having trouble paying, you can work out a solution together before the invoice becomes significantly overdue. A collaborative approach often gets better results than a confrontational one.

Use accounting software to track and manage invoices

Keeping on top of every invoice manually becomes harder as your business grows. Accounting software helps you stay organised and reduces the admin involved in chasing payments.

With the right tools, you can generate and send invoices quickly, set up automatic payment reminders, and track the status of every invoice from a single dashboard. You can also spot patterns in late payments, such as clients who consistently pay late, so you can take action before it becomes a bigger problem.

Getting help with late payments

If your own efforts to recover a debt aren't working, there are support options available before you take legal action. These can be quicker, cheaper, and less stressful than going to court.

The Small Business Commissioner

The Small Business Commissioner (SBC) offers a free complaint service for small businesses dealing with late payments from larger firms. You can submit a complaint online, and the SBC will work to resolve the dispute on your behalf.

In 2025, the SBC recovered 3 times more overdue invoices than in 2024. As part of the 2026 reforms, the SBC will receive greater enforcement powers, including the ability to issue fines to persistent late payers. This makes the SBC an increasingly useful resource for small businesses.

Mediation and trade associations

If you belong to a trade association, check whether they offer dispute resolution services. Many associations provide mediation or arbitration for payment disputes between members.

Mediation is typically cheaper and faster than going to court. A neutral third party helps you and your client reach an agreement without the cost and formality of legal proceedings. It can also help preserve the business relationship.

When to consider legal action for late payments

Sometimes, despite your best efforts, a client won't pay. At that point, you may need to pursue the debt through formal channels. Here's how to approach it step by step.

Send a formal letter before action

Before starting legal proceedings, send a letter before action (also called a letter before claim). This puts your client on formal notice that you intend to take the matter further.

Your letter should include:

• The total amount owed, including any accrued statutory interest and debt recovery costs.
• A deadline for payment, typically 14 days from the date of the letter.
• A clear statement that you'll begin legal proceedings if the debt isn't settled by the deadline.

This letter alone is often enough to prompt payment. Many businesses prefer to settle rather than face a court claim.

Use Money Claim Online for unpaid invoices

If your letter before action doesn't result in payment, you can make a claim through Money Claim Online. This is a government service for recovering debts of up to £100,000.

You'll need to pay a court fee, which varies depending on the amount you're claiming. Once your claim is submitted, the defendant has 14 days to respond. If they don't respond or dispute the claim, you can request a county court judgment in your favour.

When to involve a debt collection agency

A debt collection agency can be a practical option when direct recovery hasn't worked. Consider this route when:

• You've sent multiple reminders with no response.
• The client is avoiding contact.
• You have several overdue invoices from the same client.
• The amount doesn't justify the cost of full legal proceedings.

Choose an agency that's a member of the Credit Services Association to make sure they follow industry standards and treat debtors fairly.
