What it is

A one-person contracting business for licensed plumbers and gasfitters. You install and repair hot water systems, gas heaters, pipework and fixtures, and service them regularly for building owners and managers.

Your first three steps

  1. Confirm your licence class covers the work you want to offer and register an ABN as a sole trader
  2. Price a second-hand ute or van, core tools and public liability insurance, and set your hourly rate against local plumbers
  3. Introduce yourself to local real estate agents and strata managers and ask to join their preferred tradie lists
Who pays

Home owners, landlords, real estate agents, strata managers and small commercial building owners.

How it makes money

Call-out fee plus hourly rate or fixed quote per job, with repeat income from agents and strata managers who send regular maintenance work.
