What this business does
Primary activity: Technical testing and analysis
Sector: Professional, scientific & technical
Investor take
PursueStrong opportunity: active trading company with strong profile and acceptable with review structure.
Opportunity 74/100 (strong), bankability 67/100. Share purchase looks the cleaner deal structure. Biggest value-creation lever: Consolidate lender relationships. 3 distinct lenders creates friction — refinance into single-lender structure for cleaner diligence. Most likely exit: share sale to pe / searcher (58/100).
🏦
Refinance opportunity
3 live charges · 3 lenders · oldest 20.0y
35/100
too messy
Refinance path is blocked by complexity. Rethink structure or expect bespoke, expensive terms.
- · Oldest live charge is 20.0 years old — likely at or near maturity.
- · 3 lenders named — inter-creditor friction likely.
- · Legal-friction score 33/100 — workable, but lender will want more DD.
Data confidence
Overall: medium (61/100)Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency
58/100
Moderate — manageable with handoverSome founder dependency, but not acute. A structured handover period should cover most risk.
FACTORS
- +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
Succession & seller-readiness
36/100
Weak signalLimited succession signal. Not a near-term off-market candidate.
SIGNALS
- secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
Red flags
cleanNo red flags detected from available public data. (This is not a clean bill of health — detailed accounts review still recommended.)
