What this business does
Primary activity: Other building completion and finishing
Sector: Construction
Investor take
Pursue
Active trading company. Family succession underway — not a classic acquisition target.

Opportunity 77/100 (strong), bankability 75/100. Same-surname younger director in place — likely family handover, not open to sale. Share purchase looks the cleaner deal structure. Most likely exit: share sale to pe / searcher (65/100).

Data confidence

Overall: high (80/100)

Strong data coverage across all sections. AI outputs should be trusted with minimal caveats.

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 64 — approaching natural succession window.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Red flags

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