What this business does
Primary activity: SIC 35110
Sector: Electricity, gas & energy
Investor take
Pursue
Active trading company with a 73-year-old founder — textbook succession opportunity.

Opportunity 80/100 (exceptional), bankability 75/100. Strong seller-intent signal (83/100, director aged 73). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Broaden director team. Sole director creates succession risk and reduces buyer comfort. Appoint a second director or strong #2. Most likely exit: share sale to pe / searcher (73/100).

Data confidence

Overall: medium (75/100)

Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

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
  • +Sole director: Only one active director — all governance concentrated on one person.
  • +Founder name in company name: Company name contains director surname "BLACK" — strong identity link between founder and business.
  • +Long-tenure founder: Senior director has been in place 23 years — deep operational knowledge concentrated in one person.
  • +Founder age: Director aged approximately 73 — succession pressure is live.

Succession & seller-readiness

100/100
Likely off-market candidate

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

SIGNALS
  • primaryFounder aged 70+: Senior director is approximately 73 years old. Natural succession window is now.
  • primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.
  • primary20+ year tenure: Director in role 23 years. Very long tenure is a classic succession signal.
  • secondaryStable-but-static management: Company is 23 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.
