Owner dependency

73/100

High — earn-out structure required

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

FACTORS

+Founder age: Director aged approximately 65 — succession pressure is live.
+Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

63/100

Strong succession signal

SIGNALS

primaryFounder aged 63+: Senior director is approximately 65. Approaching typical UK retirement age — succession thinking likely.
secondary12+ year tenure: Director in role 13 years.
supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
