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 64 — approaching natural succession window.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

50/100
Moderate signal

Some succession indicators present. Worth watching; approach if sector/strategy fits.

SIGNALS
  • primaryFounder aged 63+: Senior director is approximately 64. Approaching typical UK retirement age — succession thinking likely.

Red flags

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