What this business does

Primary activity: Security systems service activities

Sector: Administrative & support services

Investor take

Pass (distressed without resilience)

Distressed active trading company — structural issues outweigh the discount.

Opportunity 72/100 (strong), bankability 65/100. Strong seller-intent signal (78/100, director aged 75). Share purchase looks the cleaner deal structure. Biggest value-creation lever: Resolve: Confirmation statement overdue. Annual confirmation statement not filed on time. Required statutory filing — overdue is a strong discipline signal. Most likely exit: share sale to pe / searcher (65/100).

Data confidence

Overall: medium (79/100)

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

Owner dependency

91/100

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.
+Long-tenure founder: Senior director has been in place 18 years — deep operational knowledge concentrated in one person.
+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

84/100

Likely off-market candidate

Strong acquirability signals converging. Worth approaching directly — this is how off-market deals start.

SIGNALS

primaryFounder aged 70+: Senior director is approximately 75 years old. Natural succession window is now.
secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
secondary12+ year tenure: Director in role 18 years.
secondaryStable-but-static management: Company is 18 years old and no new directors in the last 3 years — succession not yet being planned internally.

Red flags

1 high ·

Confirmation statement overdue

high

Annual confirmation statement not filed on time. Required statutory filing — overdue is a strong discipline signal.
