How is this score calculated?
Financial strength1/25 pts

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

Employees14/15 pts

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

Liquidity6/20 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.

Risk deductions

Outstanding charges: -10 pts

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