Understanding the legal distinction between cash flow and balance sheet insolvency is critical to protecting both your company — and your personal position as a director.
When a company is described as insolvent, most directors assume it means one simple thing: the business cannot pay its bills. But UK insolvency law actually recognises two distinct tests of insolvency — the cash flow test and the balance sheet test — and understanding the difference could be the single most important thing you do to protect your company, and your personal position as a director.
Getting this distinction wrong leads to directors trading on while formally insolvent under the balance sheet test, unknowingly exposing themselves to wrongful trading claims under s.214 of the Insolvency Act 1986, personal liability, and even disqualification. This guide explains both tests in plain English, when each applies, and the practical steps you can take today.
In England and Wales, a company is deemed insolvent if it meets either of the two statutory tests set out in s.123 of the Insolvency Act 1986. Crucially, only one of the tests needs to be satisfied for the company to be treated as insolvent for legal purposes. This is a common misconception — directors often assume that because they are "trading through" and meeting payments, they cannot be insolvent. They are wrong.
The company is unable to pay its debts as they fall due. This is assessed in real time — can you pay your suppliers, HMRC, staff and lenders when each payment is due? It is about liquidity, not underlying asset value.
The value of the company's assets is less than the amount of its liabilities, taking into account its contingent and prospective liabilities. This is a solvency measure — even a profitable, cash-rich company can fail it if its liabilities outweigh its assets.
The distinction matters enormously. A company might be dramatically balance sheet insolvent yet paying everyone on time — perhaps because it holds illiquid assets (property, stock, a valuable contract) worth less than its total debts. Conversely, a business can be cash flow insolvent but technically balance sheet solvent, if its long-term assets comfortably exceed its liabilities.
The cash flow test asks a deliberately practical question, set out in s.123(1)(e) of the Insolvency Act 1986: is the company unable to pay its debts as they fall due? A company is deemed cash flow insolvent under this provision if a court is satisfied it cannot pay its debts — considering both the debts that are due now and those that will become due in the reasonably near future.
Yes. Since the House of Lords decision in BNY Corporate Trustee Services v Eurosail (2013), the courts recognise a "commercial" element. You must be able to meet debts as they become due in the relevant near future, not merely today's invoices. If a substantial debt (e.g., a loan repayment) falls due in three months and you have no prospect of paying it, you may already be cash flow insolvent.
A creditor can petition for winding up if the company has failed to pay a statutory demand (for a debt over £750) within 21 days, under s.123(1)(a). Even if a debt is disputed, failing to respond properly can be treated as cash flow insolvency — which is why a statutory demand must never be ignored.
Regular late payments to suppliers, borrowing from one creditor to pay another, HMRC Time-to-Pay arrangements, missed PAYE/VAT deadlines, reliance on overdraft to survive, and directors injecting personal funds to cover wages are all classic red flags.
Creditors commonly rely on returned cheques, bounced direct debits, undischarged statutory demands, County Court Judgments, or simply a creditor's petition supported by evidence the debt is unpaid and unpayable.
Key point: Cash flow insolvency focuses on liquidity. You can be cash flow insolvent even if your balance sheet looks healthy — for example, if your assets exceed liabilities but you simply cannot convert them into cash fast enough to pay your debts as they arise.
The balance sheet test, in s.123(2) of the Insolvency Act 1986, catches companies that might be cash-rich and current on payments but are nonetheless insolvent because the value of their assets is less than the amount of their liabilities, taking into account contingent and prospective liabilities.
The balance sheet test is not simply "what's on the accounts". It requires taking into account contingent and prospective liabilities — debts that may arise in the future, such as personal guarantees you've signed for the company, lease commitments, warranty claims or potential litigation. A company can be forced into insolvency because of a future liability it hasn't yet been called upon to pay. This is precisely why many directors who think they are "asset-rich" are surprised to discover they are legally insolvent.
If you're unsure whether your company has crossed the balance sheet threshold, work through this sequence with your accountant:
Use realisable (break-up) values, not book values or going-concern values. A fixed asset worth £500k on paper may only realise £200k under a forced sale. Be brutally honest — the court will be.
Include every creditor, loan, lease, guarantee, and prospective claim — not just those in the accounts. If in doubt, the overwhelming case law favours including it.
If liabilities determinably exceed assets across the medium term, the balance sheet test is likely met, per the BNY v Eurosail "point of no return" approach.
Keep a written record of your solvency assessment and the basis for continuing to trade. This is critical evidence if your position is later challenged by a liquidator.
Both tests are legally independent — a company only needs to fail one to be treated as insolvent. Here's how they differ in practice.
| Aspect | Cash Flow Test | Balance Sheet Test |
|---|---|---|
| Legal basis | s.123(1)(e) and s.123(1)(a) Insolvency Act 1986 | s.123(2) Insolvency Act 1986 |
| Core question | Can you pay debts as they fall due? | Do liabilities exceed assets? |
| Focus | Liquidity — cash flow, timing, near-future commitments | Solvency — the value balance of the whole business |
| Typical proof | Unpaid statutory demand, bounced cheques, missed HMRC payments, creditor petition | Audited/signed accounts, independent valuations, contingent liabilities |
| Triggers ability to challenge even if paying? | Yes, if you can't meet near-future debts | Yes — the classic "asset rich, insolvent" scenario |
| Relevant to wrongful trading? | Yes — any point you couldn't pay is relevant | Yes — even more commonly relied upon by liquidators |
| Easiest for a creditor to trigger | Yes — via statutory demand/winding-up petition | Often requires more formal evidence |
| Can you be insolvent this way while solvent the other? | Yes — asset rich but can't pay now | Yes — paying everyone but liabilities exceed assets |
Here is the reality many directors discover too late: the moment a company becomes insolvent on either test, a director's duties fundamentally shift. The company's interests become secondary to the interests of its creditors, and knowingly trading on can expose you to personal liability.
If, knowing (or being expected to conclude) the company has no reasonable prospect of avoiding insolvent liquidation, you continue trading, the court can order you to contribute to the company's assets. Both cash flow and balance sheet insolvency can trigger this.
The test is objective: what a reasonably diligent director with your knowledge and skills ought to have known. Ignorance is not a defence.
When insolvency is likely, a director must act in the interests of the company's creditors as a whole. This is not optional — it is a statutory duty under s.172(3) Insolvency Act 1986, reinforced by the statement of best practice and the 2015 corporate governance changes.
Any transaction that preferentially benefits a director or related party at creditors' expense can be set aside and the director made personally liable.
Under the Company Directors Disqualification Act 1986, failing to consider creditors' interests properly, or trading while insolvent, can lead to disqualification for up to 15 years — even where no personal loss has been suffered. Disqualification restricts you from acting as a director of any UK company.
A director escapes wrongful trading if, once insolvency is identified, they take every step with a view to minimising the potential loss to creditors. Documented, decisive action — formal rescue advice, a recovery plan, an immediate CVL where justified — is your strongest protection.
The balance sheet test does not require the company to be irretrievably insolvent forever. Per BNY v Eurosail, it is met when the company has reached the "point of no return" — where there is no reasonable prospect of avoiding insolvent liquidation. Many directors inadvertently cross this line while still trading. That is precisely when wrongful trading exposure begins.
Determining whether your company has crossed either insolvency threshold is something you should do proactively, not when a statutory demand arrives. Here is a practical, director-focused roadmap.
List every debt due over the next 3–6 months. Include HMRC, suppliers, loan repayments, and any debt that will mature. Then model your incoming cash. If inflows cannot cover outflows, your company is cash flow insolvent in the near term — regardless of asset values.
