What this business does
Primary activity: Other business support service activities n.e.c.
Sector: Administrative & support services
Investor take
Pass (distressed without resilience)
Active trading company. Family succession underway — not a classic acquisition target.

Opportunity 74/100 (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 (73/100).

Data confidence

Overall: medium (77/100)

Adequate coverage. AI outputs are reliable for the sections scored high; verify the rest in diligence.

Owner dependency

81/100
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
  • +Two-director setup: Only two active directors — typical of owner-managed SMEs but limits succession.
  • +Founder age: Director aged approximately 66 — succession pressure is live.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

21/100
No succession signal

No meaningful acquirability indicators from public data.

SIGNALS
  • primaryFamily succession underway: Not a takeover target — KOELLN, Harmen Alexander (same surname) appointed 2024-10-11. Pattern consistent with intra-family handover.
  • primaryFounder aged 63+: Senior director is approximately 66. Approaching typical UK retirement age — succession thinking likely.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.

Red flags

1 med · 1 low
Name changed recently
medium

Name changes can be benign (rebrand) but can also precede distress, phoenix activity, or buyer concealment.

Evidence: 2024-10-16: certificate-change-of-name-company

Multiple registered office changes
low

Multiple address changes in a short period can indicate operational instability or admin disorder.
