What this business does
Primary activity: SIC 38210
Sector: Water supply & waste
Investor take
Pursue
Strong opportunity: active trading company with exceptional profile and bankable structure.

Opportunity 80/100 (exceptional), 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: share sale to pe / searcher (73/100).

🏦

Refinance opportunity

2 live charges · 2 lenders · oldest 27.1y

50/100
clean up first

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

  • · Oldest live charge is 27.1 years old — likely at or near maturity.
  • · Two lenders — manageable, but coordination required.
  • · Legal-friction score 33/100 — workable, but lender will want more DD.

Owner dependency

66/100
High — earn-out structure required

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

FACTORS

  • +Senior director age: Director aged approximately 62 — approaching natural succession window.

Succession & seller-readiness

46/100
Moderate signal

Some succession indicators present. Worth watching; approach if sector/strategy fits.

SIGNALS
  • secondaryFounder aged 58+: Senior director is approximately 62. Early succession window.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.

Red flags
