What this business does
Primary activity: SIC 35300
Sector: Electricity, gas & energy
Investor take
Pursue
Active trading company. Family succession underway — not a classic acquisition target.

Opportunity 82/100 (exceptional), bankability 75/100. Same-surname younger director in place — likely family handover, not open to sale. Share purchase looks the cleaner deal structure. Most likely exit: share sale to pe / searcher (73/100).

🏦

  • · Oldest live charge is 30.1 years old — likely at or near maturity.
  • · Two lenders — manageable, but coordination required.
  • · Legal-friction score 15/100 — clean.

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 34 years — deep operational knowledge concentrated in one person.
  • +Founder age: Director aged approximately 72 — succession pressure is live.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

56/100
Strong succession signal

Multiple signals suggest succession is on the horizon. Candidate for proactive outreach.

SIGNALS
  • primaryFamily succession underway: Not a takeover target — LUMSDEN, Jaimie (same surname) appointed 2022-02-01. Pattern consistent with intra-family handover.
  • primaryFounder aged 70+: Senior director is approximately 72 years old. Natural succession window is now.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • primary20+ year tenure: Director in role 34 years. Very long tenure is a classic succession signal.
  • secondaryStable-but-static management: Company is 34 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.
