Unpaid invoices are not a minor inconvenience for UK small businesses. They are a genuine threat to survival. Research by the Federation of Small Businesses consistently shows that late payment and non-payment cause cash flow crises that push profitable, well-run businesses into insolvency. If a customer or client is refusing to pay, you are not powerless, and you do not have to write the debt off.
This post sets out the practical recovery steps available to UK SMEs, in order of escalation, so you can act quickly and confidently when a business relationship breaks down over an unpaid invoice.
How Widespread Is the Problem?
UK SMEs are collectively owed tens of billions of pounds in overdue invoices at any one time. The average small business waits more than 30 days beyond agreed payment terms before receiving payment, and a significant proportion never receive payment at all. For companies operating on tight margins, even a single large unpaid invoice can trigger a cash flow crisis that affects wages, supplier payments, and growth plans.
Debtors, whether businesses or individuals, frequently rely on the assumption that creditors will give up or accept a reduced settlement rather than pursue recovery through formal channels. That assumption is often correct, because most SMEs do not know their options, or feel uncertain about how to use them. Understanding what tools are available is the first step to getting paid.
Before You Escalate: Confirm the Basics
Before taking formal action, confirm three things:
- The debt is due: check your contract and invoice terms to confirm the payment deadline has genuinely passed and that the invoice was properly served
- The debt is undisputed: formal enforcement routes (statutory demands, winding-up petitions) cannot be used against a genuinely disputed debt without exposing you to an abuse of process claim
- You have the right debtor: if the customer is a limited company, make sure you are pursuing the company entity that contracted with you, not a parent, subsidiary, or connected business that did not sign the agreement
If the debt is undisputed and overdue, you can move through the following stages as quickly as the situation demands.
Stage 1: Internal Chasing and a Final Demand
Most businesses begin with phone calls and emails. If those have not produced payment, the next internal step is a formal final demand: a letter clearly stating the amount owed, the original due date, the interest accruing under the Late Payment of Commercial Debts (Interest) Act 1998, and a firm deadline, typically seven to ten days, after which you will take formal action.
A well-drafted final demand on headed paper, signed by a director or senior officer, has a different psychological effect on a debtor than a chaser email. It signals that you are serious. Many debts are resolved at this stage, particularly where the debtor is simply prioritising other creditors and needs to understand that you will not wait indefinitely.
If the final demand produces no response or a commitment that is then broken, move to the next stage immediately. Do not issue multiple warnings without following through; it trains debtors to ignore you.
Stage 2: Instruct a Commercial Debt Collection Agency
Instructing a professional commercial debt collection agency is usually the right next step for most SME debts. A specialist agency sends formal demand letters on professional headed paper, makes direct contact with the debtor’s accounts or finance teams, and applies consistent pressure that is difficult to ignore in the way internal chasers are.
The key advantages of using an agency at this stage:
- Most reputable agencies operate on a no win no fee basis, so there is no upfront cost and no risk if the debt cannot be recovered
- Agency contact signals that the creditor has formally escalated the matter, which often triggers payment from debtors who were previously unresponsive
- Agencies can carry out basic asset and address tracing if the debtor has moved or become hard to contact
- They can advise on the most effective next step if initial demands fail, whether that is a statutory demand, court action, or an insolvency petition
For the majority of undisputed business debts, a professional agency resolves the matter without the need for court proceedings, saving time and legal costs for both sides.
Stage 3: Issue a Statutory Demand
A statutory demand is a formal written demand for a debt of more than £750 owed by a company, or more than £5,000 owed by an individual. It is a pre-insolvency tool: if the debtor does not pay, secure the debt, or apply to set the demand aside within 21 days, you can apply to wind up the company (if a corporate debtor) or petition for bankruptcy (if an individual).
The statutory demand must be served correctly, which typically means personal service by a process server on an individual, or service at the company’s registered office. Incorrect service can give the debtor grounds to set the demand aside.
The statutory demand route is most effective for undisputed debts against solvent companies that are choosing not to pay. A demand threatening a winding-up petition is taken seriously by company directors, particularly where the company has ongoing supplier relationships, a credit rating to protect, or bank financing that would be jeopardised by insolvency proceedings.
It should not be used where the debt is genuinely disputed, where the debtor company is already insolvent (in which case court-based insolvency proceedings may be more appropriate), or where you have reason to believe the debtor will use the dispute route to delay proceedings.
Stage 4: Issue County Court Proceedings
If a statutory demand is set aside, ignored, or simply not the right route for your situation, the next step is to issue a money claim through the County Court. For most business debts up to £100,000, this can be done online via the HMCTS Money Claim Online (MCOL) portal.
If the debtor does not respond within 14 days, you can apply for a default County Court Judgment (CCJ) immediately. This is the most common outcome for undisputed debts where the debtor has simply failed to engage. A CCJ:
- Is a legally binding court order requiring the debtor to pay
- Registers on the debtor’s credit file for six years
- Gives you access to a range of enforcement tools
- Is recoverable with interest and court costs added to the debt
If the debtor files a defence, the claim proceeds to a hearing. Small claims under £10,000 go to the Small Claims Track, which is designed to be accessible without legal representation, though instructing a specialist for complex or high-value claims is advisable.
Stage 5: Enforce the Judgment
A CCJ does not guarantee payment; it creates the legal right to enforce. If the debtor still does not pay after judgment, you have several enforcement options:
High Court Enforcement Officers
For debts over £600, you can transfer the County Court Judgment to the High Court and instruct High Court Enforcement Officers (HCEOs). HCEOs can attend the debtor’s premises, take control of goods, and arrange their sale to satisfy the debt. A visit from an HCEO often produces immediate payment because the consequences, loss of business equipment or stock, are immediate and visible.
Attachment of Earnings
Where the debtor is an individual (such as a sole trader or personal guarantor), you can apply for an order directing their employer to deduct payments from wages directly. This is not available against limited companies.
Third-Party Debt Orders
A third-party debt order freezes money held in the debtor’s bank account and redirects it to the creditor. You need to know which bank holds the debtor’s funds; asset tracing services can help establish this.
Charging Orders
A charging order secures the judgment debt against property owned by the debtor. It does not produce immediate payment but ensures you receive your money when the property is sold or remortgaged. You can subsequently apply for an order for sale, though courts are cautious about forcing the sale of a primary residence.
When to Consider Insolvency Proceedings Against a Company
For undisputed debts over £750 owed by a limited company, you can petition the court to wind up the company if the debt remains unpaid following a statutory demand. This is a serious step that should only be taken where:
- The debt is genuinely undisputed and clearly evidenced
- The company is solvent but choosing not to pay
- You have made every reasonable attempt to recover the debt
Filing a winding-up petition is publicly registered and immediately visible to the company’s bank, which will typically freeze the company’s accounts upon receipt. This alone often triggers immediate payment from companies that were previously unresponsive. If the petition proceeds to hearing and the company is wound up, an Insolvency Practitioner is appointed to realise the company’s assets and distribute them to creditors, though recovery in a genuine insolvency is rarely 100 pence in the pound.
Protecting Your Business from Future Late Payment
While recovering the current debt is the priority, it is worth reviewing your credit controls to reduce future exposure:
- Credit check new business customers before extending credit. Companies House, credit reference agencies, and the Register of Judgments can all flag risk before you take on a new client
- Use written contracts that clearly specify payment terms, late payment interest, and the consequences of non-payment
- Include a retention of title clause in contracts for goods, so that ownership does not pass until payment is made in full
- Invoice promptly and accurately. Errors or delays in invoicing give debtors an excuse to delay payment
- Follow up immediately when invoices become overdue. The longer a debt sits unpaid, the harder it becomes to recover
Invoice financing and trade credit insurance are also worth considering if your business regularly extends significant credit to customers. These tools can protect cash flow while maintaining commercial relationships.

Frequently Asked Questions
How long does commercial debt recovery take in the UK?
Timeline varies significantly depending on the route taken. A professional debt collection agency typically makes first contact within 24 to 48 hours and many undisputed debts are resolved within two to four weeks without court action. If court proceedings become necessary, obtaining a default County Court Judgment on an uncontested claim usually takes two to four weeks from filing. Contested claims can take several months. High Court Enforcement after judgment can produce results within days to weeks, depending on the debtor’s circumstances.
Is it worth going to court for a small business debt?
For undisputed debts over around £500, court action is usually worth pursuing, especially if the debtor is solvent and simply refusing to pay. Court fees are recoverable from the debtor if judgment is granted, and a CCJ can be enforced through High Court Enforcement Officers, attachment of earnings, or charging orders on property. For very small amounts or where the debtor is clearly insolvent, the cost-benefit calculation is less favourable. A specialist debt collection agency will give you an honest view of whether court action is likely to produce a return in your specific case.
Can I claim interest on unpaid business invoices in the UK?
Yes. Under the Late Payment of Commercial Debts (Interest) Act 1998, UK businesses can claim statutory interest on overdue business-to-business invoices at 8% above the Bank of England base rate. Interest accrues from the date the invoice became overdue. You can also claim a fixed compensation amount per invoice: £40 for debts under £1,000, £70 for debts between £1,000 and £9,999, and £100 for debts over £10,000. These rights apply even if your contract does not mention interest, provided the debt is a qualifying commercial transaction.
What is the difference between a debt collection agency and a solicitor for recovering business debts?
A commercial debt collection agency specialises in recovering unpaid invoices and typically operates on a no win no fee basis, making it a low-risk option for businesses. Agencies use formal demand letters, tracing services, and escalation tactics to secure payment without court proceedings. A solicitor is needed when the debt is disputed, when legal proceedings are required, or when you need formal legal advice on your position. Many businesses start with an agency and only instruct solicitors if the debt is defended or if specialist legal action is needed, such as an insolvency petition against a limited company.
How do I check whether a business debtor is worth pursuing?
Before committing to court action, it is worth running basic checks on the debtor company. Companies House shows the company’s registered status, filed accounts, and whether it is subject to any existing insolvency proceedings. The Register of Judgments, Orders and Fines shows existing CCJs. Asset tracing services can identify company property, vehicles, or bank accounts. A company that is already in administration or liquidation is unlikely to yield a return through ordinary court action, though you may be able to register as a creditor in the insolvency process. A specialist agency will carry out these checks as part of its assessment.
Can I recover a debt from a dissolved company?
It is possible but complex. If a company has been dissolved, assets that were not distributed at dissolution pass to the Crown as bona vacantia. You can apply to restore the company to the register via Companies House, which reactivates it and allows normal debt recovery or insolvency proceedings to commence. Restoration applications can take several months and involve court costs. Where a director has given a personal guarantee, you may be able to pursue the individual directly regardless of whether the company is dissolved. Legal advice is essential before taking steps to restore a dissolved company.
What should I do if the customer disputes the invoice?
First, establish whether the dispute is genuine or a delaying tactic. Request the specific grounds of the dispute in writing. If the dispute is minor, consider whether a small concession would resolve the matter faster than prolonged chasing. For substantive disputes, gather all supporting evidence: contracts, purchase orders, delivery notes, emails, and signed acceptance. A genuinely disputed debt will need to go through a defended court claim if negotiation fails, and you may benefit from legal advice at that stage. A debt collection agency cannot issue a statutory demand or take winding-up steps against a company where the debt is genuinely disputed, so it is important to distinguish disputed from simply unpaid invoices early in the process.
