Longevity15/15 pts

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

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.
