Owner dependency

79/100

High — earn-out structure required

Material founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.

FACTORS

+Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
+Senior director age: Director aged approximately 60 — approaching natural succession window.
+Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
+No director turnover: Company is 15 years old with no director changes — suggests a very tight-knit founder team never broadened.

Succession & seller-readiness

59/100

Strong succession signal

Multiple signals suggest succession is on the horizon. Candidate for proactive outreach.

SIGNALS

secondaryFounder aged 58+: Senior director is approximately 60. Early succession window.
secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
secondary12+ year tenure: Director in role 15 years.
supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.

Red flags

clean

No red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
