What this business does
Primary activity: SIC 38210
Sector: Water supply & waste
Investor take
PursueActive trading company with a 66-year-old founder — textbook succession opportunity.
Opportunity 77/100 (strong), bankability 85/100. Strong seller-intent signal (78/100, director aged 66). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Broaden director team. Sole director creates succession risk and reduces buyer comfort. Appoint a second director or strong #2. Most likely exit: share sale to pe / searcher (73/100).
🏦
Refinance opportunity
6 live charges · 2 lenders · oldest 51.8y
30/100
under pressure
Refinance would be pressure-driven, not opportunity-driven. Expect tighter margins and covenant scrutiny.
- · Oldest live charge is 51.8 years old — likely at or near maturity.
- · Two lenders — manageable, but coordination required.
- · Distress signals active — lender appetite narrows.
Data confidence
Overall: medium (70/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
100/100
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
- +Sole director: Only one active director — all governance concentrated on one person.
- +Founder name in company name: Company name contains director surname "MCKENNA" — strong identity link between founder and business.
- +Founder age: Director aged approximately 66 — succession pressure is live.
Succession & seller-readiness
75/100
Likely off-market candidateStrong acquirability signals converging. Worth approaching directly — this is how off-market deals start.
SIGNALS
- primaryFounder aged 63+: Senior director is approximately 66. Approaching typical UK retirement age — succession thinking likely.
- primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.
- secondaryStable-but-static management: Company is 62 years old and no new directors in the last 3 years — succession not yet being planned internally.
