Primary activity: Other specialised construction activities n.e.c.

Sector: Construction

Investor take

Pursue

Active trading company with a 73-year-old founder — textbook succession opportunity.

Opportunity 80/100 (exceptional), bankability 67/100. Strong seller-intent signal (63/100, director aged 73). 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 (65/100).

🏦

Refinance opportunity

4 live charges · 3 lenders · oldest 27.2y

35/100

too messy

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

· Oldest live charge is 27.2 years old — likely at or near maturity.
· 3 lenders named — inter-creditor friction likely.
· Legal-friction score 35/100 — workable, but lender will want more DD.

Data confidence

Overall: medium (58/100)

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