How the Prompt Payment Code works and whether it actually helps

Waiting for payment can be one of the most frustrating parts of running a UK small business. You've done the work, you've sent the invoice, and now you wait. The UK's Prompt Payment Code (PPC) was designed to tackle this exact problem, but many business owners are unclear on what it is, who it applies to, and whether it has any real power.

This article cuts through the jargon. We'll explain exactly what companies commit to when they sign the Prompt Payment Code, how it's enforced, and what its limitations are in the real world. Most importantly, we'll help you understand whether it's a tool you can actually use to get your invoices paid faster, or just a well-intentioned but toothless pledge.

What is the Prompt Payment Code?

The Prompt Payment Code (PPC) is a voluntary code of practice for UK businesses and public bodies. It’s not a law, but a public commitment that a company makes to pay its suppliers on time. The code is administered by the Office of the Small Business Commissioner (SBC) on behalf of the government.

Its primary goal is to improve payment cultures across the UK, encouraging good practice and challenging the acceptance of late payment. Any organisation can apply to become a signatory, from a multinational corporation to a local council or a small limited company. By signing, they agree to uphold a specific set of standards in how they manage their payments to suppliers.

The list of signatories is public, creating a degree of transparency. The idea is that this public commitment, and the reputational risk of failing to meet it, will motivate large organisations to treat their smaller suppliers more fairly.

What Do Signatories Actually Commit To?

At the heart of the Prompt Payment Code are three core pledges. A signatory company publicly commits to:

1. Pay suppliers on time: This is the headline commitment, with specific targets.
2. Give clear guidance to suppliers: This means being transparent about payment procedures, points of contact, and how to handle queries or disputes.
3. Encourage good practice: Signatories are expected to encourage their own supply chains to adopt the code, helping the principles of prompt payment to filter down.

The most critical part for a small business is the detail within that first pledge. The code sets different targets depending on the size of the supplier.

Since 2021, the rules for signatories have become stricter. They must pay 95% of their invoices within agreed terms, and they are specifically forbidden from changing payment terms retrospectively or engaging in any other practices that harm their supply chain.

The key targets are:

• To pay 95% of all invoices within 60 days.
• To pay 95% of all invoices from small businesses (defined as having fewer than 50 employees) within 30 days.

This 30-day term for small businesses is the most powerful part of the code. It means a large signatory client should not be forcing 90-day or 120-day terms onto their small suppliers.

Here’s a simple breakdown of the core payment commitment for a signatory:

Supplier Size	Target Payment Timeframe	Compliance Target
Small Business (fewer than 50 employees)	Within 30 days	Must pay 95% of invoices on time
Medium/Large Business (50+ employees)	Within 60 days	Must pay 95% of invoices on time

In addition to these targets, signatories must also have a clear and effective process for handling any payment disputes and must provide a named contact or contact point for suppliers to use for payment queries.

How is the Code Enforced?

This is where reality starts to bite. Because the PPC is a voluntary code and not a law, its enforcement mechanisms are not the same as a court order. The Small Business Commissioner (SBC) is the referee, not a bailiff.

The enforcement process generally works as follows:

1. Complaint: A supplier (or a representative body) can make a complaint to the SBC that a signatory is not upholding the code. This is typically done when there's a pattern of late payments, not just a single overdue invoice.
2. Investigation: The SBC will investigate the complaint. They look at the company's payment data, which large companies are legally required to report twice a year under the 'Duty to Report' regulations. This data shows what percentage of invoices they pay in under 30 days, 31-60 days, and over 60 days.
3. Action Plan: If the SBC finds the signatory is non-compliant, the first step is usually to work with them to create an action plan for improvement. The goal is to get them back on track.
4. Suspension and Removal: If the signatory fails to improve or refuses to engage, the SBC has the power to publicly suspend or remove them from the code. Their name is added to a "naughty list" on the SBC website.

The primary "teeth" of the PPC is this "name and shame" element. For a large, publicly-listed company, being formally removed from a government-backed code for poor payment practices can cause significant reputational damage and negative press. However, the SBC cannot force a company to pay a specific invoice. Its role is to police compliance with the code at a systemic level, not to act as a debt collector for individual businesses.

The Big Question: Does the Prompt Payment Code Actually Work?

This is the multi-million-pound question for every freelancer and small business owner. The answer is nuanced: it helps, but it is not a silver bullet.

The Case For: Why the PPC is a Positive Force

• It Sets a Standard: The code establishes a clear, public benchmark for what "good" looks like. The 30-day target for small businesses is a powerful reference point you can use in negotiations.
• Public Accountability: The public register of signatories and, more importantly, the list of suspended/removed companies, creates genuine reputational risk for large organisations that care about their corporate image.
• A Non-Legal Escalation Route: Complaining to the SBC provides a formal channel to raise issues about a signatory's payment culture without immediately resorting to expensive and relationship-damaging legal action.
• Due Diligence Tool: Before taking on a large new client, you can quickly check if they are a signatory. While not a guarantee, it's a small but positive signal that they have at least acknowledged the importance of fair payment.

The Reality Check: The Limitations of the PPC

• It's Voluntary: This is the code's single biggest weakness. The worst offenders for late payment are often the companies that would never dream of signing up in the first place.
• The "95% of Invoices" Loophole: A signatory can be fully compliant with the code while still paying 5% of its invoices late. If you're a small supplier to a corporate giant that processes 100,000 invoices a year, that's up to 5,000 late payments that don't technically breach the code's target. If you're in that 5%, the code offers little direct help.
• Enforcement is Slow and Indirect: The SBC process is about investigating systemic failures, not resolving your immediate cash flow crisis. It can take months, and the outcome is a change in the company's overall process, not necessarily an instant payment for your outstanding invoice.
• It Doesn't Replace Credit Control: You absolutely cannot rely on the PPC to manage your accounts receivable. It is a background standard, not an active tool for chasing debt. Your own diligent, professional follow-up process is what will get you paid.

In short, the PPC is a valuable part of the landscape that helps apply pressure on big businesses, but it is not the tool you reach for when an invoice hits 15 days overdue.

The PPC vs. Your Statutory Rights: Know the Difference

Many business owners confuse the voluntary Prompt Payment Code with their actual legal rights. This is a critical distinction. Your most powerful tools are enshrined in UK law, specifically the Late Payment of Commercial Debts (Interest) Act 1998.

This Act is law, not a voluntary code. It applies to almost all business-to-business transactions automatically, unless you've explicitly agreed to different terms in your contract. It gives you three key rights when a commercial invoice is paid late.

1. Statutory Interest: You have the legal right to charge interest on the overdue amount. This is calculated at 8% plus the Bank of England's base rate. This rate is significantly higher than typical commercial interest and is designed to be a real deterrent.
2. Fixed Sum Compensation: In addition to interest, you can claim a one-off compensation payment for every late invoice to cover the cost of recovery. The amount depends on the size of the debt.
   • For debts up to £999.99, you can claim £40.
   • For debts between £1,000 and £9,999.99, you can claim £70.
   • For debts of £10,000 or more, you can claim £100.
3. Reasonable Costs: If the fixed compensation doesn't cover your full costs of recovering the debt (e.g., legal fees), you can claim these "reasonable costs" as well.

Here’s how the two compare directly:

Feature	Prompt Payment Code (PPC)	Late Payment of Commercial Debts Act 1998
Nature	Voluntary Code of Practice	UK Law (Statute)
Applies to	Signatory companies only	Almost all B2B transactions in the UK
Key Term	Aim to pay 95% of small biz invoices in 30 days	Default 30-day payment term if not otherwise agreed
Remedy	Complaint to the SBC about systemic issues	Legal right to claim interest & fixed compensation
Enforcement	SBC investigation, potential public removal from code	Your own action, ultimately through the courts
Purpose	To improve the UK's payment culture	To provide a legal remedy for individual late payments

Your statutory rights are your real teeth. The PPC is a standard of good behaviour.

Practical Steps for a Small Business

So, how should you use this knowledge?

1. Before You Start Work

• Check the PPC Register: If you're about to engage with a large new customer, it takes 30 seconds to check if they are a signatory. If they are, it's a small plus. If they've been suspended, it's a major red flag.
• Get a Contract: Your most important tool is a clear contract or proposal that states your payment terms upfront. Whether that's 14, 30, or 45 days, get it in writing and agreed. This is far more powerful than relying on the PPC.

2. When an Invoice is Overdue

• Don't Lead with the PPC: Your first reminder should be polite and professional. An aggressive opening like "As a signatory to the Prompt Payment Code..." is likely to backfire and damage the relationship.
• Follow a Process: Your best defence is a consistent credit control process. Start with a gentle nudge on the day the invoice is due, followed by firmer reminders at set intervals. Automating this process with a tool like InvoiceReminder ensures you follow up consistently and professionally without the manual effort, escalating from gentle nudges to firmer requests based on rules you set.
• Use the PPC as an Escalation Point: If a known signatory is ignoring your standard reminders and is weeks overdue, mentioning their public commitment to the code in a firmer email can be an effective tactic. Frame it professionally: "As you are a signatory to the Prompt Payment Code, which commits to paying small business suppliers within 30 days, we would appreciate prompt settlement of this overdue invoice."

3. When to Use Your Statutory Rights

• Adding statutory interest and compensation is a powerful move, but it's a commercial decision. For a long-term client who is a few days late, it may be overkill. For a client who is ignoring you at 60 days past due, it's an essential tool.
• You can either re-issue the invoice with the charges added, or mention your right to add them in your final notice email before considering legal action.

4. When to Complain to the SBC

• Reserve this for systemic issues. If a PPC signatory is consistently paying every one of your invoices 30-60 days late, despite your chasing, they are likely failing to meet their 95% target. In this case, a complaint to the SBC is warranted, as it points to a wider problem that they are tasked with addressing.

The Prompt Payment Code is a positive initiative, but it’s no replacement for diligent, robust, and consistent credit control in your own business.

Frequently asked questions

Can I force a company to pay me by reporting them to the Prompt Payment Code?

No. The Small Business Commissioner investigates a signatory's overall compliance with the code, but they do not have the power to compel a specific payment for an individual invoice. To enforce payment of a debt, you need to use your statutory rights under the Late Payment Act, potentially leading to court action.

What's the difference between the Prompt Payment Code and the Late Payment Act?

The Prompt Payment Code (PPC) is a voluntary set of good practice principles that companies sign up to. The Late Payment of Commercial Debts Act is UK law that gives you a legal right to claim interest and compensation on overdue B2B invoices from almost any business, whether they've signed the code or not.

How do I check if a company is a signatory to the Prompt Payment Code?

The Office of the Small Business Commissioner maintains a public online directory of all current signatories. They also publish a separate list of companies that have been suspended or removed from the code for non-compliance. You can search these lists on their official website.

Is it worth signing my own small business up to the Prompt Payment Code?

Yes, it can be a positive step. Signing up is free and signals to your own suppliers and customers that you are committed to fair payment practices. As the commitments reflect good business practice anyway, it can enhance your company's reputation at no cost.

Does the 30-day payment term in the PPC override my contract?

No. The payment terms you explicitly agree in your contract are the legally binding ones. The PPC is a commitment by signatories to aim to pay 95% of their small business invoices within 30 days. It sets a standard of behaviour and can be a useful point of leverage, but it does not automatically rewrite your agreed contractual terms.

What happens if a company is removed from the PPC?

When a company is removed, they are publicly named on the Small Business Commissioner's website. This is designed to create reputational damage and act as a deterrent. However, there are no direct financial penalties or legal sanctions issued by the SBC, and the company can continue to trade as normal.
