Serava.AI has mapped 15,802 acquisition-ready plumbing companies in NSW.

Not all are actively listed for sale: the majority are off-market targets that have not yet engaged a broker.
Revenue for plumbing companies in NSW varies by size, but most SMB-scale targets in our database fall in the $1M to $15M annual revenue range. Serava.AI provides revenue estimates benchmarked from payroll data, OSM business data, and SBA loan records.
Key signals for a high-quality plumbing acquisition include: a long operating history (15+ years in business), stable recurring or repeat revenue, strong online ratings (4.0+ with 20+ reviews), an established local customer base, and a skilled technical workforce. Serava.AI's Acquisition Fit Score (0 to 100) weighs all of these factors and benchmarks each company against your specific buyer criteria.

Plumbing companies in NSW typically trade at 3x to 6x EBITDA, depending on revenue concentration, customer contracts, and owner dependency. A business with $2M revenue and 12% EBITDA margins ($240k EBITDA) would price between $720k and $1.44M. Businesses with recurring contracts, a long operating history, and clean books command higher multiples.
