What this business does
Primary activity: Construction of other civil engineering projects n.e.c.
Sector: Construction
Investor take
Pursue
Strong opportunity: active trading company with strong profile and bankable structure.

Opportunity 78/100 (strong), bankability 75/100. 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. 2 live charge(s) created 15+ years ago — likely paid but undischarged. Clean register. Most likely exit: strategic trade sale (63/100).

🏦

Refinance opportunity

5 live charges · oldest 45.8y

45/100
under pressure

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

  • · Oldest live charge is 45.8 years old — likely at or near maturity.
  • · Single lender — cleanest path to refinance.
  • · Cashflow trend is negative — lender view likely cautious.

Data confidence

Overall: medium (79/100)

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

Owner dependency

68/100
High — earn-out structure required

Material founder dependency. Consider a 2-3 year earn-out and build in a handover plan before completion.

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 21 years — deep operational knowledge concentrated in one person.

Succession & seller-readiness

66/100
Strong succession signal

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

SIGNALS
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • primary20+ year tenure: Director in role 21 years. Very long tenure is a classic succession signal.
  • secondaryStable-but-static management: Company is 100 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.
