What does ownership return?
Settlement discount is guaranteed when you pay within terms. Rebates and dividends are not guaranteed — they are paid only if declared by the Board, and reflect how the Co-op performs.
Settlement discount applies when invoices are paid within agreed terms. Rebates and dividends are not guaranteed and may not be paid in any given year — they are paid only if and when declared by the Board, and reflect the Co-op's financial result.
Your spend.
Your returns.
You have to buy plumbing supplies — that's not changing. The question is whether the business you buy from pays you back. Plug in your monthly spend and see what 5, 10 or 20 years at the Co-op puts in your pocket.

Owner-Members.
The member pricing alone makes it worthwhile. Everything else — the branch, the services, the people — that's the bit you don't expect.
Sorted insurance and ute finance through the Co-op. Both came back cheaper than what I'd been paying. Didn't have to chase anyone — they handled it.
The Co-op events are where I've met most of the people I trust in this industry. That network is worth more than any discount.

The Plumbers Co-op Difference
You work hard — your purchases should work hard for you. At Plumbers Co-op, we’re not just a supplier. We’re a Member-owned cooperative, proudly supporting the Australian plumbing industry since 1955.
As a Co-operative, we are unique — the only plumbing merchant in Australia that offers you, the customer, the opportunity to become a Member Shareholder in the business. All company profits are returned to Member Shareholders annually — not to outside investors or corporate executives.
“Unlike corporate chains where profits go straight to CEOs and shareholders,
all profits are returned to you, the Member-Owners.”
That means every dollar you spend helps build your wealth, not someone else’s bonus.
Where Profits Go: Back to You
When you become a Co-op Member, you’re not just a customer — you’re a shareholder. You share in the success of the Co-op through annual dividends, rebates, and settlement discounts.
Here’s how it works:
Profit Returns: Every year, profits are distributed back to Members.
Discounts & Rebates: Receive settlement discounts and annual rebates on your purchases.
Dividends: The more shares you hold, the greater your return.
Reinvestment Option: Reinvest your rebates and dividends into additional Co-op shares to build long-term financial strength.
No Annual Fees: Your membership is an investment, not a subscription.

About Us
Every year, Aussie plumbers unknowingly give away billions in profits – straight into the pockets of private owners and corporate shareholders.
Most plumbing supply businesses are built that way: a few people or corporate shareholders get rich, while the plumbers doing the work miss out.
At the Plumbers Co-op, we’ve flipped the model. Plumbers own us. When a plumber Owner-Member shops with us, they’re not building someone else’s empire – they’re building their own. We are the only plumbing supplies company where the buyer can be the profit-maker. And more.
Most of our Owner-Members reinvest the 2.5% settlement discount, rebates or dividends which has the effect of building their Co-op wealth. Doing this means spending as little as $5,000 a month over a career - on supplies you will buy anyway - can earn passive income of $325,000*.
We started in 1955 and now have approximately 6,000 plumber-shareholders. Join and spend with the Co-op and you’re not just a customer — You’re an Owner. Shareholder. Profit-Taker.
