Types of Plumbing Businesses
Residential Service Plumbing: Service calls, repairs, fixture installation. Lower startup costs, steady demand, emergency opportunities.

New Construction: Working with builders and contractors. Steady work, competitive bidding, seasonal variations.
Specialized Services: Drain cleaning, water heater specialists, sewer line repair. Higher margins, focused expertise.
The UK plumbing sector continues strong growth with ongoing demand for qualified plumbers. Self-employed plumbers earn £35,000-£50,000/year, with experienced professionals exceeding £60,000 in major cities.
2. Licensing Path: Apprentice to Master
Important: There is no nationwide plumbing license. Requirements vary significantly by state and municipality. Always check your local requirements.
Three-Tier Licensing System
1. Apprentice Plumber (Entry Level):
- Work under supervision of licensed plumber
- Learn basic tasks and safety procedures
- Usually requires high school diploma/GED
- No prior experience needed
2. Journeyman Plumber (Independent Worker):

- Most common: 4,000-8,000 hours (2-4 years)
- Pass state journeyman exam

- Cannot pull permits or run business in most states
3. Master Plumber (Business Owner/Supervisor):
- Requirements: 2-4 years as licensed journeyman

- Required to own plumbing contracting business
