Primary activity: Plumbing, heat and air-conditioning installation
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: 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).

Owner dependency

88/100
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 60 — approaching natural succession window.
  • +No director turnover: Company is 11 years old with no director changes — suggests a very tight-knit founder team never broadened.

Succession & seller-readiness

60/100
Strong succession signal

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

SIGNALS
  • secondaryFounder aged 58+: Senior director is approximately 60. Early succession window.
  • primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.

Red flags

clean
No red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
