How is this score calculated?
Financial strength13/25 pts

Net worth compared to all companies in the same SIC code with published accounts. Top quartile earns the full 25 points.

Employees10/15 pts

Workforce size relative to sector peers from the most recent accounts. A larger team generally signals commercial scale.

Liquidity16/20 pts

Current assets ÷ current liabilities. A ratio above 2× earns full marks; between 1–2× scores partially; below 0.5× scores minimal points.

Longevity15/15 pts

One point per year of operation since incorporation, capped at 15. Older companies have a proven track record.

Filing compliance15/15 pts

Full 15 points when both annual accounts and confirmation statement are filed on time. Points are deducted for each overdue filing.

Maximum score is 100. Deductions apply for insolvency history, outstanding charges, going concern doubt, or disqualified officers.
