What this business does
Primary activity: Technical testing and analysis
Sector: Professional, scientific & technical
Investor take
PursueActive trading company. Family succession underway — not a classic acquisition target.
Opportunity 80/100 (exceptional), bankability 75/100. Same-surname younger director in place — likely family handover, not open to sale. Share purchase looks the cleaner deal structure. Biggest value-creation lever: Discharge stale live charges. 1 live charge(s) created 15+ years ago — likely paid but undischarged. Clean register. Most likely exit: share sale to pe / searcher (65/100).
🏦
Refinance opportunity
2 live charges · 2 lenders · oldest 29.8y
50/100
clean up first
Refinance viable after a tidy-up — address the highlighted items first.
- · Oldest live charge is 29.8 years old — likely at or near maturity.
- · Two lenders — manageable, but coordination required.
- · Legal-friction score 33/100 — workable, but lender will want more DD.
Data confidence
Overall: medium (77/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
73/100

FACTORS
- +Founder age: Director aged approximately 75 — succession pressure is live.
- +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.
Succession & seller-readiness
20/100

- primaryFounder aged 70+: Senior director is approximately 75 years old. Natural succession window is now.
Red flags
