What this business does
Primary activity: Other specialised construction activities n.e.c.
Sector: Construction
Investor take
PursueStrong opportunity: active trading company with strong profile and bankable structure.
Opportunity 73/100 (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 (58/100).
Data confidence
Overall: medium (78/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
80/100
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.
- +No director turnover: Company is 14 years old with no director changes — suggests a very tight-knit founder team never broadened.
Succession & seller-readiness
58/100
Strong succession signalMultiple signals suggest succession is on the horizon. Candidate for proactive outreach.
SIGNALS
- primarySole active director: Only one director in control. No visible successor — buyers solve the succession problem.
- secondary12+ year tenure: Director in role 14 years.
- supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
Red flags
cleanNo red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
