How to start a plumbing business
Every building needs a plumber eventually, and good ones are always booked. Here is how to go from qualified plumber to running your own business, including the PIRB registration that lets you sign off your own work.
Get qualified and registered with PIRB
Plumbing is a trade: a qualification and the plumbing trade test are the foundation. The Plumbing Industry Registration Board (PIRB) registers plumbers at different levels, from learner to licensed plumber. Your level decides what work you may certify.
Plumbing Certificates of Compliance
Plumbing work that falls under the national building regulations and plumbing standards, such as hot water systems and geysers, water supply and drainage, must meet the National Building Regulations and the relevant standards. PIRB-registered plumbers issue the PIRB Certificate of Compliance. PIRB is a professional registration body, not a statutory regulator, so its CoC is not required by national law everywhere: it becomes required when a municipal by-law, an insurer or a contract asks for it. That is common, especially for geyser replacements, which makes registration close to essential if you want that work.
Set up the business
- Register the company with CIPC and sort your tax: how to register
- A reliable vehicle, the core tools, and a trade account at a plumbing supplier
- Public liability insurance: water damage claims can be expensive
- COIDA and UIF as soon as you employ an assistant
Where the steady work comes from
Emergency call-outs bring in customers, but steady income comes from relationships: insurance assessors and panels, property managers, body corporates, estate agents, builders who need a reliable plumber, and solar or heat-pump installers. Joining an industry body such as IOPSA adds credibility.
