What this business does
Primary activity: SIC 46620
Sector: Wholesale & retail
Investor take
Pursue
Active trading company. Family succession underway — not a classic acquisition target.

Opportunity 79/100 (strong), bankability 67/100. Same-surname younger director in place — likely family handover, not open to sale. Share purchase looks the cleaner deal structure. Biggest value-creation lever: Consolidate lender relationships. 6 distinct lenders creates friction — refinance into single-lender structure for cleaner diligence. Most likely exit: share sale to pe / searcher (73/100).

🏦

Refinance opportunity

7 live charges · 6 lenders · oldest 39.0y

35/100
too messy

Refinance path is blocked by complexity. Rethink structure or expect bespoke, expensive terms.

  • · Oldest live charge is 39.0 years old — likely at or near maturity.
  • · 6 lenders named — inter-creditor friction likely.
  • · Legal-friction score 25/100 — workable, but lender will want more DD.

Owner dependency

84/100
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 31 years — deep operational knowledge concentrated in one person.
  • +Senior director age: Director aged approximately 64 — approaching natural succession window.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

36/100
Weak signal

Limited succession signal. Not a near-term off-market candidate.

SIGNALS
  • primaryFamily succession underway: Not a takeover target — BURN, Andrew Robert (same surname) appointed 2023-06-12. Pattern consistent with intra-family handover.
  • primaryFounder aged 63+: Senior director is approximately 64. Approaching typical UK retirement age — succession thinking likely.
  • secondaryTwo-director governance: Small-team governance. Succession depth is thin but not absent.
  • primary20+ year tenure: Director in role 31 years. Very long tenure is a classic succession signal.
  • supportingClean filings + long tenure: Disciplined long-tenure operator — classic lifestyle-business pattern that often sells quietly.
