What this business does
Primary activity: SIC 35110
Sector: Electricity, gas & energy
Investor take
Pursue
Active trading company with a 78-year-old founder — textbook succession opportunity.

Opportunity 82/100 (exceptional), bankability 80/100. Strong seller-intent signal (63/100, director aged 78). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Discharge stale live charges. 1 live charge(s) created 15+ years ago — likely paid but undischarged. Clean register. Most likely exit: share sale to pe / searcher (65/100).

🏦

Refinance opportunity

1 live charge · oldest 33.8y

65/100
clean up first

Refinance viable after a tidy-up — address the highlighted items first.

  • · Oldest live charge is 33.8 years old — likely at or near maturity.
  • · Single lender — cleanest path to refinance.
  • · Legal-friction score 25/100 — workable, but lender will want more DD.

Data confidence

Overall: medium (70/100)

Owner dependency

83/100
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
  • +Long-tenure founder: Senior director has been in place 34 years — deep operational knowledge concentrated in one person.
  • +Founder age: Director aged approximately 78 — succession pressure is live.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

80/100
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 78 years old. Natural succession window is now.
  • primary20+ year tenure: Director in role 34 years. Very long tenure is a classic succession signal.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
