Discounts, rebates, dividends, Co-op services — everything your membership puts in your pocket, in one place.
"It's our business to make your business a success."
The Plumbers Co-op exists for one reason: to make every Owner-Member's business stronger. Not a supplier with shareholder returns to protect. Not a distributor chasing margin. A co-operative — owned by Plumbers, run for Plumbers.
- Voluntary & open membership
- Democratic Owner-Member control
- Owner-Member economic participation
- Autonomy & independence
- Education, training & information
- Co-operation among co-operatives
- Concern for community
Where it all began
On 14 April 1955, a group of Plumbers met in Pitt Street Sydney and formed Plumbers' Supplies Co-operative Limited. The idea was simple: Plumbers working together could get better deals than any single Plumber negotiating alone. Seventy years on, that founding logic still drives everything the Co-op does.
The same principle. Bigger scope.
What started with plumbing supplies has grown into finance, insurance, vehicle management and business support — the Co-op applying +6,000 Plumbers' collective buying power to every service its members need, not just the products on the shelf.
Where we are going
Service standards are rising, digital tools are improving, and the Co-op's range and services are expanding — because Owner-Members deserve a supplier that keeps pace with their businesses and anticipates what comes next.
- More relevant information, delivered across platforms
- Faster, clearer updates and communication
- Higher customer service standards in every branch
- More product training and expanded ranges
