What Is Insolvency? UK Company Insolvency Explained
Insolvency means a company cannot pay its debts. Under the Insolvency Act 1986, a company is insolvent if it fails either the cash-flow test — it cannot pay its debts as they fall due — or the balance-sheet test, where its liabilities exceed its assets. Insolvency is a financial state, not an automatic end to the business, but it changes a director's legal duties and can lead to a formal insolvency procedure.
What is insolvency?
Insolvency is the state of being unable to pay your debts. For a company, the insolvency meaning is straightforward: an insolvent company is one that cannot meet its financial obligations — either because it cannot pay its bills as they fall due, or because it owes more than it owns. In the UK, company insolvency is defined by the Insolvency Act 1986, which sets out exactly when a company is treated as unable to pay its debts.
It helps to understand what insolvency is not. Insolvency is a financial condition, not a procedure and not automatically the end of the business. A company can be insolvent for a period and still recover — through refinancing, restructuring, or a rescue procedure — provided the underlying business is viable and directors act responsibly. What insolvency does is trigger a set of legal consequences: most importantly, it changes where a director's duties lie and opens the door to formal insolvency procedures.
Insolvency in one sentence
A company is insolvent when it cannot pay its debts — either as they fall due (cash-flow) or overall (balance-sheet) — and being insolvent shifts a director's legal duty towards protecting creditors.
Because the label carries real legal weight, it matters whether a company is genuinely insolvent or simply going through a tight patch. That question is answered by two legal tests.
The two legal tests for insolvency
Under section 123 of the Insolvency Act 1986, a company is deemed unable to pay its debts if it fails either of two tests. A company only has to fail one of them to be insolvent — and it is entirely possible to pass one and fail the other.
The cash-flow test
Section 123(1)(e). The company is unable to pay its debts as they fall due. In plain terms: even if the balance sheet looks healthy, if you cannot meet your bills, wages, tax or loan repayments on time, you are cash-flow insolvent.
Example: a business with valuable premises but no cash to pay this month's PAYE.
The balance-sheet test
Section 123(2). The value of the company's liabilities — including contingent and prospective liabilities — is greater than the value of its assets. In plain terms: the company owes more than it is worth.
Example: a company still paying its bills but carrying debts far exceeding everything it owns.
The distinction matters in practice. A company can be balance-sheet solvent but cash-flow insolvent — profitable on paper yet unable to pay a supplier on time — or the reverse. The cash-flow test is usually the first to bite, because running out of money to pay bills is what typically forces the issue. If either test is failed, the company is insolvent, and directors need to treat the situation accordingly.
This is general guidance on UK law, not legal advice on your specific circumstances. If persistent shortfalls are the problem, our guide to managing cash-flow problems covers practical steps.
Insolvency vs bankruptcy
One of the most common misunderstandings is treating "insolvency" and "bankruptcy" as the same thing. In UK law they are not. Bankruptcy applies only to individuals — sole traders and private people who cannot pay their personal debts. A limited company is never made bankrupt; a company that cannot pay its debts becomes insolvent, and if it is wound up, it goes through liquidation rather than bankruptcy.
So when people say a company has "gone bankrupt", what they usually mean is that it has become insolvent and entered a formal insolvency procedure such as administration or liquidation. The distinction is not just semantic: individual bankruptcy and corporate insolvency are governed by different parts of the law, involve different procedures, and have different consequences.
The simple rule
People go bankrupt. Companies become insolvent. A limited company cannot be made bankrupt — it is wound up through liquidation.
What insolvency means for directors
This is the part that catches directors out. While a company is solvent, directors owe their duties primarily to the company and its shareholders. But once a company is insolvent, or in the zone of insolvency, that duty shifts: directors must act in the interests of the company's creditors as a whole. Protecting creditor value becomes the priority, and decisions have to be judged against that standard.
The most serious risk is wrongful trading. If directors continue to trade and take on further credit when they knew, or ought to have concluded, that there was no reasonable prospect of avoiding insolvent liquidation, a court can order them to contribute personally to the company's assets. Other risks include liability for misfeasance, for making preference payments that unfairly favour one creditor over others, and for trading while insolvent without proper regard to creditors.
Where personal liability comes from
Directors are usually shielded from company debts by limited liability — but that protection can fall away through wrongful trading, misfeasance, preferences, or personal guarantees. Understanding your directors' duties and responsibilities the moment insolvency is in view is the single best way to protect yourself.
The main UK insolvency procedures
Once a company is insolvent, there are several formal routes it can take, each implemented by a licensed insolvency practitioner. Which one fits depends on a single question: is there a viable business worth saving? The table below shows how the main procedures line up.
| Procedure | Purpose | Who is in control? |
|---|---|---|
| Administration | Rescue or sell the business under a legal moratorium | Administrator (an IP) |
| CVA | Repay creditors a proportion over time; company survives | Directors keep control |
| CVL | Directors choose to wind up an insolvent company | Liquidator (an IP) |
| Compulsory liquidation | Company wound up by the court, often after a petition | Liquidator / Official Receiver |
Administration
An insolvency practitioner takes control, protected by a statutory moratorium that freezes creditor action, and works to rescue the company, sell the business, or get creditors a better result than liquidation. See our full company administration guide.
Company Voluntary Arrangement (CVA)
A binding agreement to repay creditors an agreed proportion of debts over a fixed term while directors keep control and the company keeps trading. Read the full CVA guide.
Creditors' Voluntary Liquidation (CVL)
Directors of an insolvent company decide to wind it up, appointing a liquidator to sell assets and distribute proceeds. See voluntary liquidation for how it works.
Compulsory liquidation
The company is wound up by court order, usually after a creditor presents a winding-up petition. This is covered in our compulsory liquidation guide.
Rescue is not always a formal procedure. Where insolvency is caught early, options such as company restructuring or turnaround finance can resolve the problem without any procedure at all. For a side-by-side comparison of every route, see turnaround vs the alternatives and CVA vs administration.
The role of a licensed insolvency practitioner
Every formal insolvency procedure in the UK must be carried out by a licensed insolvency practitioner (IP) — a professional authorised and regulated to take formal appointments over insolvent companies and individuals. Only a licensed IP can be appointed as an administrator, a supervisor of a CVA, or a liquidator.
An insolvency practitioner has a duty to act in the interests of creditors as a whole, and as an officer of the court must be even-handed and independent. Their role is to assess the company's position, recommend the appropriate procedure, and then implement it — whether that means rescuing the business, arranging a sale, or realising assets and distributing them in the correct legal order of priority.
Importantly, taking advice from a licensed IP or a turnaround adviser does not commit you to any procedure. Early advice is often what keeps a company out of formal insolvency, by identifying restructuring or refinancing options while there is still time to use them.
Warning signs a company is becoming insolvent
Insolvency rarely arrives without warning. The following signs suggest a company is heading towards, or already in, an insolvent position — and each is a prompt to take advice sooner rather than later:
Persistent cash-flow pressure
Constantly juggling payments, relying on overdrafts, or being unable to meet wages, rent or supplier bills on time.
Mounting HMRC arrears
Falling behind on VAT, PAYE or corporation tax, or repeatedly needing Time to Pay arrangements. See dealing with HMRC debt.
Creditor pressure and CCJs
Final demands, county court judgments, statutory demands, or a threatened winding-up petition.
Eroding balance sheet
Liabilities creeping above assets, negative net worth, or drawing on directors' loans and personal funds to stay afloat.
Maxed-out finance
Facilities at their limit, lenders declining further credit, or reliance on high-cost borrowing to cover day-to-day costs.
Sustained losses
Trading at a loss month after month with no clear route back to profit, and margins that no longer cover overheads.
What to do if your company is insolvent
If your company is insolvent, or you suspect it may be, the single most important thing is to act early and take advice. Insolvency narrows a director's options with every week that passes — the earlier you engage, the more routes remain open, from refinancing and restructuring to a CVA or a managed turnaround that avoids any formal procedure.
1 Take advice from a licensed IP or turnaround adviser
Get an honest, independent assessment of viability and options before making decisions. Early advice protects both the business and you personally.
2 Put creditors' interests first
Once insolvent, act in the interests of creditors as a whole. Avoid taking on credit you cannot repay and do not make payments that unfairly prefer one creditor.
3 Keep clear records
Document the decisions you make and why. A clear record of acting reasonably is your best protection against later claims of wrongful trading.
Insolvency is a serious situation, but it is not the end of the road — many viable businesses trade on and recover. What matters is recognising it early and getting the right advice before the choices run out.
Frequently asked questions
What does it mean if a company is insolvent?
A company is insolvent when it cannot pay its debts. Under the Insolvency Act 1986 it is treated as unable to pay its debts if it fails either the cash-flow test — it cannot pay its debts as they fall due — or the balance-sheet test, where its liabilities, including contingent and prospective liabilities, exceed its assets. Insolvency does not automatically mean the company must close, but it triggers legal duties for directors and may lead to a formal insolvency procedure.
What are the two tests for insolvency?
There are two tests under section 123 of the Insolvency Act 1986. The cash-flow test (section 123(1)(e)) asks whether the company can pay its debts as they fall due. The balance-sheet test (section 123(2)) asks whether the value of the company's liabilities, including contingent and prospective liabilities, exceeds the value of its assets. A company only needs to fail one test to be insolvent, and it can be balance-sheet solvent but cash-flow insolvent, or the reverse.
What is the difference between insolvency and bankruptcy?
In the UK, bankruptcy applies only to individuals and sole traders who cannot pay their personal debts. Companies do not go bankrupt — they become insolvent and enter corporate procedures such as administration, a CVA, or liquidation. People often use "bankruptcy" loosely to mean any business failure, but technically a limited company is never made bankrupt; it is either insolvent, or wound up through liquidation.
What should a director do if their company is insolvent?
Act early and take advice from a licensed insolvency practitioner or turnaround adviser. Once a company is insolvent, a director's duty shifts from shareholders to protecting the interests of creditors as a whole. Directors should stop taking on credit they cannot repay, keep clear records of their decisions, avoid making payments that unfairly prefer one creditor, and get advice before the options narrow. Acting early protects the business and reduces personal risk of wrongful trading.
Can an insolvent company keep trading?
Not safely, without advice. Insolvency does not require a company to stop trading immediately, and a viable business may trade on while it is rescued or restructured. But once directors know, or ought to know, there is no reasonable prospect of avoiding insolvent liquidation, continuing to trade and run up further debts can amount to wrongful trading, which can make directors personally liable. The safe course is to take advice from a licensed insolvency practitioner as soon as insolvency is suspected.
What are the main insolvency procedures in the UK?
The main procedures are administration, where an insolvency practitioner takes control to rescue or sell the business under a moratorium; a company voluntary arrangement (CVA), a binding agreement to repay creditors over time while directors keep control; creditors' voluntary liquidation (CVL), where directors choose to wind up an insolvent company; and compulsory liquidation, where the court winds up a company, usually after a winding-up petition. Each is implemented by a licensed insolvency practitioner and suits a different situation.
