What this business does
Primary activity: Electrical installation
Sector: Construction
Investor take
Pursue
Strong opportunity: active trading company with strong profile and bankable structure.

Opportunity 75/100 (strong), bankability 80/100. High owner-dependency — earn-out structure likely required for clean transition. 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 (58/100).

🏦

Refinance opportunity

1 live charge · oldest 27.9y

45/100
under pressure

Refinance would be pressure-driven, not opportunity-driven. Expect tighter margins and covenant scrutiny.

  • · Oldest live charge is 27.9 years old — likely at or near maturity.
  • · Single lender — cleanest path to refinance.
  • · Distress signals active — lender appetite narrows.

Data confidence

Overall: medium (79/100)

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