Late payments can turn a healthy order book into a cash flow crisis. You may have done the work, paid staff, covered materials, raised the invoice and waited. Then the payment date passes, and the money still does not arrive.
The 2026 late payment reforms are welcome. They may help improve payment culture over time. But if you are under pressure now, the more urgent question is simpler: what can you do today if unpaid invoices are putting your business at risk?
Late Payment Reforms: What You Need to Know
The Small Business Protections Bill was introduced to Parliament in May 2026. It is designed to strengthen the rules around late payment and give smaller suppliers more protection when larger customers delay paying them. Under the Small Business Protections Bill, the government has announced measures including a 60-day cap on payment terms for large firms paying smaller suppliers, stronger powers for the Small Business Commissioner, and action on poor payment practices in construction.
The reforms also build on existing rules around statutory interest. Current GOV.UK guidance on late commercial payments says statutory interest is 8% plus the Bank of England base rate for business-to-business transactions, unless a different contractual rate applies.
In plain English, the reforms aim to make it harder for larger businesses to delay payment without consequence. After all, late payment is not just an admin issue. It affects wages, tax, rent, supplier confidence and your ability to keep trading.
But there is an important point to keep in mind. New rules do not automatically pay an old invoice. They do not instantly stop HMRC pressure, and they do not replace missing working capital overnight. If your business is already under strain, you may need a plan now, not just protection later.
Why Late Payment Becomes Serious So Quickly
Late payment creates a chain reaction. You are owed money by one customer. Because of that, you delay paying a supplier. The supplier tightens your terms. You use money set aside for VAT to pay wages. HMRC arrears begin to build. A bank balance that looked manageable suddenly feels fragile.
This is common. Research from the Small Business Commissioner found that late payments are estimated to cost the UK economy almost £11 billion a year, affect more than 1.5 million businesses each year, and cause around 38 business closures every day. It also found that businesses affected by late payment spend an average of 86 hours a year chasing overdue invoices.
That is time, energy and cash you should be able to use for the business.
When you are already stretched, even one large unpaid invoice can cause real pressure. You may still be profitable on paper, but unable to pay bills when they fall due. That is when late payment starts to move from frustration into financial risk.

What the Reforms May Change
The late payment reforms may help in several ways.
Firstly, they may reduce unfairly long payment terms. They may make larger businesses think more carefully before delaying supplier payments. Additionally, the Small Business Commissioner may gain more power to investigate and penalise poor payment behaviour. They may also make it easier for smaller suppliers to challenge unfair practice without feeling completely exposed.
For many businesses, these are positive steps.
It may also help with confidence. If stronger rules make customers pay closer to agreed terms, suppliers can plan with more certainty. That can improve cash flow, reduce borrowing and make it easier to invest.
In construction, the reforms may be especially relevant because delayed payments and retentions can put pressure on the whole supply chain. If you rely heavily on one payer, or you are exposed to main contractor insolvency, the impact can move quickly from one business to another.
Still, reform is not the same as recovery. If cash flow is already tight, you should not wait for the law to solve the immediate problem.
What the Reforms Will Not Fix
The new rules may improve the wider payment culture, but they cannot fix every situation.
They may not:
- recover an invoice that is already seriously overdue
- repair a damaged relationship with a key customer
- stop supplier accounts being put on hold
- prevent HMRC from chasing unpaid tax
- fund payroll while you wait
- make an insolvent company solvent again
This is why it helps to separate two questions. The first is: “What are my rights when a customer pays late?” The second is: “Can my business survive the cash flow gap?”
Both matter. But if the second question is becoming urgent, you need to look at the whole financial position.
When Overdue Invoices Become Insolvency Risk
A company can be insolvent even when it has work booked in, assets on paper, or customers who say they will pay soon. In simple terms, insolvency usually comes down to two tests.
The first is the cash flow test. Can the company pay its debts when they fall due?
The second is the balance sheet test. Are the company’s liabilities greater than its assets?
If either test is failed, there may be an insolvency risk. Insolvency in the UK is defined as a situation where a company cannot pay its debts as they fall due or its liabilities exceed its assets.
Warning signs can include:
- using VAT or PAYE money to cover trading costs
- regularly choosing which creditor to pay next
- relying on one overdue invoice to meet payroll
- being refused further credit by suppliers
- receiving legal threats, default notices or statutory demands
- increasing personal borrowing to support the company
- having no realistic back-up plan if payment does not arrive
At this point, late payments become a risk for the future of your company. That does not mean you have failed, but it does mean that the position needs to be reviewed carefully and quickly.
Practical Steps to Take If Customers Don’t Pay
Start with the basics, even if the situation feels stressful. Check the invoice, payment terms and due date. Make sure there is no genuine dispute about the work, goods, amount or paperwork. Then chase in writing and keep a clear record of what has been said.
If the customer still does not pay, consider whether statutory interest or recovery costs apply. This can help, but it should be used carefully. Sometimes it is commercially sensible. Sometimes it may worsen a relationship that is already fragile.
You should also look at the tax position. If you have accounted for VAT on an invoice but the customer has not paid, bad debt relief may be relevant. There are rules and time limits, so it should not be treated as automatic, but it can be an important cash flow point.
It also helps to prepare a short-term cash flow forecast. Even a simple 13-week view can show whether the problem is temporary or more serious.
Ask yourself:
- What must be paid this week?
- What can be delayed without making the situation worse?
- Which payments are essential to keep trading?
- What happens if the overdue invoice is not paid for another 30 days?
- What happens if it is never paid?
That final question can feel uncomfortable. But it is often the question that gives you the clearest answer.
Handling HMRC Arrears
Late payment often leads to tax arrears. This can happen even where the business itself is viable. You expected a customer payment to clear before VAT was due. The customer missed the date. You paid wages and key suppliers instead. The VAT bill remained unpaid.
One missed payment can turn into two. Then HMRC letters arrive. Interest and penalties may be added. The pressure increases.
If this is happening, do not ignore it. HMRC debt can escalate, especially if returns are late or communication breaks down.
A Time to Pay arrangement may be possible where the business can afford a realistic repayment plan. But you should not agree to payments that depend on hope. If the company cannot keep up with current tax and arrears, a short-term arrangement may only delay a bigger problem.
This is where early advice can help. You need to know whether the business can recover, whether business restructuring is realistic, or whether a formal insolvency route should be considered.

When to Restructure Your Business
Sometimes, what your business needs is breathing space, better cash control and a structured plan. Restructuring can involve reducing costs, changing payment terms, negotiating with creditors, reviewing contracts, refinancing where appropriate, or using a formal process such as a Company Voluntary Arrangement.
The right route depends on the facts.
A business may be viable if the core trade is sound, margins still work, and the debt can be managed over time. In that case, the focus may be on stabilising cash flow and creating a realistic repayment plan.
But if losses are continuing, debts are increasing and there is no clear route back to profitability, restructuring may not be enough.
Acting early usually gives you more options. Waiting until a creditor starts court action can reduce the choices available.
When to Consider Liquidation
Sometimes a business cannot recover. That can be very hard to accept, especially if late payment has played a major part. You may feel that the business would have survived if customers had paid on time.
Even so, once insolvency is clear, the focus has to shift. Directors need to think about creditors’ interests and avoid making the position worse.
A Creditors’ Voluntary Liquidation is a formal way to close an insolvent limited company. It is used when the company cannot afford to carry on trading and cannot repay what it owes. It allows a licensed insolvency practitioner to wind the company up properly, notify creditors, deal with assets and bring the company to an orderly close.
In March 2026, CVLs accounted for 73% of company insolvencies in England and Wales, according to the Insolvency Service’s company insolvency statistics.
If liquidation is the right route, taking advice early can help you avoid drifting into compulsory liquidation and reduce the risk of making decisions that are later criticised.
Director Duties During Financial Difficulty
When insolvency is possible, your duties change in practice.
You still need to manage the company, but you must pay close attention to creditors’ interests. That means you should avoid taking on new debt unless there is a realistic plan to repay it. You should be careful about paying one creditor ahead of others without a proper reason. You should keep records of decisions and avoid moving assets out of the company without advice.
You should also be careful with deposits, customer payments and new orders. If you are not sure the company can deliver the work, taking more money may create further risk.
A licensed insolvency practitioner can help you understand where you stand. That does not mean you are committing to liquidation. It means you are getting regulated advice before the pressure removes your options.
Common Questions About Late Payment and Insolvency
Will the late payment reforms get my old invoices paid?
Not automatically. The reforms may improve payment behaviour over time, but current overdue invoices still need to be chased, negotiated or considered as part of your wider cash flow position.
Can I keep trading if customers owe me money?
Possibly. The key question is whether the company can still pay its debts as they fall due, or whether there is a realistic plan to bring debts under control. If continued trading is likely to increase creditor losses, you should take advice.
Should I charge interest on late payments?
You may be able to charge statutory interest on business-to-business debts, depending on your contract and the circumstances. It can be useful, but it should sit alongside a wider credit control plan.
What if HMRC is chasing me because customers have not paid?
Speak to HMRC and take advice. You may be able to agree a payment plan if the business is viable. If the company cannot afford current tax and arrears, you may need restructuring or insolvency advice.
Does liquidation mean I have done something wrong?
No. Many directors use liquidation because the company cannot continue and they want to deal with creditors properly. In many cases, taking early advice and choosing an orderly route is the responsible step.
