5 Red Flags in UK Company Accounts Every Credit Controller Must Know

Why Red Flags in Accounts Matter

Most bad debts don't come from nowhere. In the majority of cases, the signals were present in the company's accounts or public records weeks or months before the insolvency event. The challenge is knowing what to look for — especially when many UK SMEs file abbreviated accounts that reveal only a fraction of their financial position.

Here are the five red flags that should trigger immediate further investigation before extending credit.

1. Negative or Rapidly Declining Equity

What to look for: Total equity on the balance sheet that is negative, or equity that has declined by more than 30% year-on-year.

Equity represents what the company actually owns after all liabilities are deducted. When equity turns negative, the company technically owes more than it owns — a state known as technical insolvency.

For UK private companies, this can be obscured by low share capital. A company with £100 share capital and £50,000 of accumulated losses will show negative equity on paper, even if it is trading profitably. Always look at the trend: is equity growing, stable, or deteriorating?

Watch for: Equity below zero, or a year-on-year decline of more than 20% with no explanation in the accounts.

2. Current Ratio Below 0.8

What to look for: Current assets divided by current liabilities giving a result below 0.8.

The current ratio measures whether a company can pay its short-term bills from its short-term assets. A ratio below 1.0 means current liabilities exceed current assets — the company is relying on future cash generation or new borrowing to pay today's creditors.

While UK service businesses regularly operate at 1.0–1.4 without difficulty (their cash conversion cycle is fast), a ratio below 0.8 is a genuine warning signal regardless of sector.

Watch for: Current ratio below 0.8 — especially combined with other red flags.

3. Gearing Above 5x

What to look for: Total liabilities divided by equity exceeding 5x (500%).

Gearing measures how leveraged a company is. A gearing ratio of 5x means the company has five times more debt than equity. For UK SMEs with minimal share capital, gearing ratios can be high even for healthy companies — which is why the equity ratio (equity as a percentage of total assets) is often a more reliable measure.

An equity ratio below 10% combined with high gearing is a strong signal that the company has very little financial cushion against a downturn.

Watch for: Gearing above 5x alongside equity ratio below 15%.

4. Shrinking or Negative EBITDA Margin

What to look for: EBITDA margin declining significantly year-on-year, or turning negative.

EBITDA (Earnings Before Interest, Tax, Depreciation, and Amortisation) is a proxy for operating cash generation. A company with a positive EBITDA is generating cash from its core operations — even if its net profit is reduced by debt service or depreciation. When EBITDA turns negative, the company is burning cash from operations.

This red flag is only detectable when a full P&L is filed. Many UK SMEs file balance-sheet-only accounts, making this analysis impossible — which is itself a limitation worth noting.

Watch for: EBITDA margin declining by more than 5 percentage points year-on-year, or turning negative.

5. Overdue Accounts or Gazette Notices

What to look for: Accounts more than 3 months overdue at Companies House, or any entry in The Gazette.

These are not strictly accounting red flags — they are public record signals. But they are among the most powerful predictors of near-term insolvency:

• Overdue accounts correlate strongly with financial distress (companies struggling with day-to-day finances often deprioritise statutory filings)
• Gazette notices — particularly winding-up petitions and administration appointments — are near-definitive insolvency events that often appear before the Companies House status changes

Watch for: Any Gazette entry for the company, or accounts more than 3 months past their due date.

Key Takeaways

• Negative or declining equity is a fundamental solvency warning
• Current ratio below 0.8 signals short-term payment stress
• High gearing (above 5x) with low equity ratio leaves no financial cushion
• Declining EBITDA means the business is consuming rather than generating cash
• Overdue accounts and Gazette notices are public record signals that often precede formal insolvency by months
