What this business does

Primary activity: Plumbing, heat and air-conditioning installation

Sector: Construction

Investor take

Pursue

Strong opportunity: active trading company with strong profile and acceptable with review structure.

Opportunity 79/100 (strong), bankability 67/100. 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 (65/100).

🏦

Refinance opportunity

12 live charges · 6 lenders · oldest 45.6y

15/100

under pressure

Refinance would be pressure-driven, not opportunity-driven. Expect tighter margins and covenant scrutiny.

· Oldest live charge is 45.6 years old — likely at or near maturity.
· 6 lenders named — inter-creditor friction likely.
· Cashflow trend is negative — lender view likely cautious.
