Cash flow insolvency test explained under UK law, including section 123 Insolvency Act 1986, key case law, practical indicators, legal consequences, and how courts assess a company's ability to pay debts as they fall due.
The cash flow test is one of the central legal measures used in England and Wales to determine whether a company is insolvent. It forms part of the statutory framework under section 123 of the Insolvency Act 1986. The test focuses on whether a company can meet its debts when they fall due, rather than its overall asset position.
It is used by courts, creditors, insolvency practitioners, and directors when assessing financial distress and deciding whether formal insolvency procedures such as liquidation or administration may be appropriate.
Legal Basis of the Cash Flow Test
The cash flow test is set out in section 123(1)(e) of the Insolvency Act 1986, which states that a company is deemed unable to pay its debts if it cannot pay them as they fall due.
This statutory test is one of two primary insolvency indicators, the other being the balance sheet test under section 123(2), which considers whether liabilities exceed assets.
The cash flow test is widely regarded as the most commonly applied insolvency assessment in practice because it reflects day-to-day financial reality.
Courts have confirmed that the test is not limited to overdue invoices at a single point in time. It requires a broader assessment of whether the company can pay debts in the reasonably near future, based on commercial evidence and financial projections.
Meaning of the Cash Flow Test
Core principle
A company fails the cash flow test when it cannot pay debts as they fall due from available liquid resources.
This includes:
- Debts already due and unpaid
- Debts becoming due in the near future
- Obligations that are practically unavoidable, such as tax, rent, and supplier payments
It is a forward-looking assessment, not a snapshot of bank balances on a single day.
Key legal interpretation
Courts assess:
- Payment history and patterns of arrears
- Current cash position and liquidity
- Expected future inflows and outflows
- Access to credit or refinancing options
Temporary cash shortages may not be sufficient on their own if the company can realistically meet obligations shortly afterwards. However, persistent inability to pay creditors is strong evidence of insolvency.
How Courts Apply the Cash Flow Test
1. Reasonably near future assessment
The court does not only look at debts that are due today. It considers liabilities falling due in the foreseeable future, depending on the nature of the business and its trading cycle.
For example:
- A seasonal business may be assessed differently from a service company with regular monthly obligations
- Long-term contracts and predictable income streams are relevant
2. Commercial realism
The assessment is practical rather than purely accounting-based. Courts examine whether projected income is realistically achievable or speculative.
3. Evidence used
Typical evidence includes:
- Management accounts
- Cash flow forecasts
- Bank statements
- Creditor correspondence
- Payment history with HMRC and suppliers
Leading Case Law Principles
Re Cheyne Finance Ltd [2007]
The court confirmed that cash flow insolvency includes consideration of debts falling due in the reasonably near future, not only immediate obligations.
BNY Corporate Trustee Services Ltd v Eurosail [2013 UKSC 28]
The Supreme Court clarified that the test requires a commercial and realistic assessment of whether a company has reached a position where it cannot meet debts as they fall due, considering future liabilities and financial context.
The decision emphasised that insolvency is not triggered by temporary or technical difficulties but by a genuine inability to meet obligations over time.
Difference Between Cash Flow and Balance Sheet Insolvency
Cash flow insolvency
- Focus: liquidity
- Question: can the company pay debts when due?
- Trigger: missed or imminently missed payments
Balance sheet insolvency
- Focus: overall financial position
- Question: do liabilities exceed assets?
- Includes contingent and future liabilities
A company can fail one test but not the other. Either is sufficient for a finding of insolvency under section 123.
Practical Indicators of Cash Flow Insolvency
Common warning signs include:
- Repeated late payments to suppliers
- HMRC arrears (VAT, PAYE, corporation tax)
- Reliance on overdrafts or short-term borrowing
- Constant rescheduling of creditor payments
- Difficulty meeting payroll obligations
These indicators are not definitive on their own but often support a finding that the company cannot meet debts as they fall due.
Legal and Commercial Consequences
1. Winding-up petitions
Creditors may rely on cash flow insolvency to petition the court to wind up a company.
2. Director duties
Once insolvency is likely or established, directors must prioritise creditor interests and avoid increasing losses.
3. Wrongful trading risk
Continuing to trade while unable to meet debts may expose directors to personal liability if losses increase.
4. Access to formal insolvency procedures
Cash flow insolvency often leads to:
- Administration
- Company voluntary arrangements (CVA)
- Liquidation
Time Limits and Threshold Evidence
A statutory demand for unpaid debt (commonly over £750) left unpaid for 21 days can be used as evidence that a company is unable to pay its debts. This is often relied upon in winding-up proceedings.
However, courts will still examine the wider financial position rather than relying solely on procedural defaults.
Key Takeaways
The cash flow test for company insolvency assesses whether a company can pay its debts as they fall due. It is set out in section 123(1)(e) of the Insolvency Act 1986 and requires a forward-looking, commercial evaluation of liquidity and financial viability. Courts consider both current and near-future obligations, supported by financial evidence such as cash flow forecasts and payment history. Failure of this test is a key indicator of insolvency and may lead to winding-up proceedings, director liability issues, and formal insolvency procedures.
