What this business does
Primary activity: Plumbing, heat and air-conditioning installation
Sector: Construction
Investor take
Pursue
Active 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. Most likely exit: share sale to pe / searcher (65/100).

Data confidence

Overall: medium (70/100)

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

Owner dependency

98/100
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
  • +Founder name in company name: Company name contains director surname "ALLISON" — strong identity link between founder and business.
  • +Long-tenure founder: Senior director has been in place 24 years — deep operational knowledge concentrated in one person.
  • +Founder age: Director aged approximately 65 — succession pressure is live.
  • +Family involvement: Multiple officers share a surname — likely family business, which concentrates governance.

Succession & seller-readiness

30/100
Weak signal

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

SIGNALS
  • primaryFamily succession underway: Not a takeover target — ALLISON, Wilfred Benjamin (same surname) appointed 2025-04-06. Pattern consistent with intra-family handover.
  • primaryFounder aged 63+: Senior director is approximately 65. Approaching typical UK retirement age — succession thinking likely.
  • primary20+ year tenure: Director in role 24 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.
