Owner dependency
78/100
High — earn-out structure requiredMaterial 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.
- +Founder age: Director aged approximately 83 — succession pressure is live.
- +No director turnover: Company is 11 years old with no director changes — suggests a very tight-knit founder team never broadened.
Succession & seller-readiness
71/100
Strong succession signalMultiple signals suggest succession is on the horizon. Candidate for proactive outreach.
SIGNALS
- primaryFounder aged 70+: Senior director is approximately 83 years old. Natural succession window is now.
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
- supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
Red flags
cleanNo red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
