What this business does
Primary activity: Other specialised construction activities n.e.c.
Sector: Construction
Investor take
Pursue
Active trading company with a 66-year-old founder — textbook succession opportunity.

Opportunity 82/100 (exceptional), bankability 75/100. Strong seller-intent signal (93/100, director aged 66). Share purchase looks the cleaner deal structure. Most likely exit: share sale to pe / searcher (65/100).

🏦

  • · Oldest live charge is 27.1 years old — likely at or near maturity.
  • · Two lenders — manageable, but coordination required.
  • · Legal-friction score 15/100 — clean.

Data confidence

Owner dependency

91/100
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.
  • +Long-tenure founder: Senior director has been in place 27 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

86/100
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.
  • primary20+ year tenure: Director in role 27 years. Very long tenure is a classic succession signal.
  • secondaryStable-but-static management: Company is 28 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.
