What this business does
Primary activity: Construction of other civil engineering projects n.e.c.
Sector: Construction
Investor take
PursueConservative operator with a 63-year-old founder — textbook succession opportunity.
Opportunity 81/100 (exceptional), bankability 80/100. Strong seller-intent signal (70/100, director aged 63). 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: strategic trade sale (78/100).
🏦
Refinance opportunity
1 live charge · oldest 22.9y
75/100
ready
Refinance conversation should be productive — structure clean and timing right.
- · Oldest live charge is 22.9 years old — likely at or near maturity.
- · Single lender — cleanest path to refinance.
- · Legal-friction score 30/100 — workable, but lender will want more DD.
- · Profitable and stable/growing — lender coverage supportable.
Data confidence
Overall: medium (79/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
84/100
Critical — business is the founderThe 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 17 years — deep operational knowledge concentrated in one person.
- +Senior director age: Director aged approximately 63 — approaching natural succession window.
- +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
Succession & seller-readiness
69/100
Strong succession signalMultiple signals suggest succession is on the horizon. Candidate for proactive outreach.
SIGNALS
- primaryFounder aged 63+: Senior director is approximately 63. Approaching typical UK retirement age — succession thinking likely.
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
- secondary12+ year tenure: Director in role 17 years.
- supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
