Owner dependency

56/100
Moderate — manageable with handover

Some founder dependency, but not acute. A structured handover period should cover most risk.

FACTORS
  • -4 active directors: Broader management team in place — suggests transferable governance.
  • +Senior director age: Director aged approximately 63 — approaching natural succession window.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

63/100
Strong succession signal

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

SIGNALS
  • primaryFounder aged 63+: Senior director is approximately 63. Approaching typical UK retirement age — succession thinking likely.
  • secondary12+ year tenure: Director in role 14 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.)
