Owner dependency

100/100

Critical — business is the founder

The business appears inseparable from the founder. Acquisition without a serious earn-out or meaningful transition period would likely destroy value.

FACTORS

+Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
+Founder name in company name: Company name contains director surname "CALDER" — strong identity link between founder and business.
+Long-tenure founder: Senior director has been in place 17 years — deep operational knowledge concentrated in one person.
+Founder age: Director aged approximately 66 — succession pressure is live.
+Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

79/100

Likely off-market candidate

Strong acquirability signals converging. Worth approaching directly — this is how off-market deals start.

SIGNALS

primaryFounder aged 63+: Senior director is approximately 66. Approaching typical UK retirement age — succession thinking likely.
secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
secondary12+ year tenure: Director in role 17 years.
secondaryStable-but-static management: Company is 17 years old and no new directors in the last 3 years — succession not yet being planned internally.
supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
