What this business does
Primary activity: Plumbing, heat and air-conditioning installation
Sector: Construction
Investor take
Pass (distressed without resilience)
Distressed active trading company — structural issues outweigh the discount.

Opportunity 75/100 (strong), bankability 70/100. High owner-dependency — earn-out structure likely required for clean transition. 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).

Data confidence

Overall: medium (76/100)

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

Owner dependency

83/100
Critical — business is the founder

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

Succession & seller-readiness

55/100
Strong succession signal

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

SIGNALS
  • secondaryFounder aged 58+: Senior director is approximately 62. Early succession window.
  • primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.

Red flags
