Do lenders need to act in the best interests of their clients?

July 19, 2025

In an all too common occurrence of late, CBA has again ruffled the feathers of mortgage brokers running advertisements encouraging borrowers to “cut out the middle man” and deal directly with them, but why?

Big banks would much rather borrowers come to them directly instead of using a broker because it gives them more control over the conversation.

When you deal with a bank directly, you’re only presented with their own range of products, generally without full transparency about how they compare to other lenders. It also means they can avoid paying broker commissions, keeping more profit in-house. In short, going direct helps the banks maintain influence, simplify their sales process, and protect their margins while limiting a borrowers ability to explore more suitable options elsewhere.

With this in mind, in this week’s newsletter, we look at a fundamental difference between a brokers obligations to a borrower compared to the obligations of a lender. Is it any wonder brokers continue to gain market share?

Best Interests Duty (BID) is a legal obligation introduced as part of the National Consumer Credit Protection Act (NCCP) reforms in 2021. It applies specifically to mortgage brokers and mandates that brokers must always act in the best interests of their clients when providing credit assistance. This duty is not just a matter of professional ethics, it’s a legal requirement, designed to ensure that clients receive loan recommendations that genuinely suit their personal circumstances, goals, and financial needs.

To meet BID obligations, mortgage brokers must conduct a thorough individual assessment of each client, including understanding their income, expenses, future plans, and loan preferences. They are also required to compare multiple lenders and loan products before making a recommendation, ensuring the chosen option aligns with the client’s best interests, not the broker’s, nor any third party’s. Importantly, brokers must document their recommendations and provide clear written reasoning behind their advice, offering transparency and accountability throughout the lending process.

Do BID obligations extend to lenders?

No, Bert Interests Duty does not apply to lenders themselves. Banks and direct lenders are not legally required to act in the customer’s best interests in the same way brokers are. They can recommend their own products, even if better alternatives may exist elsewhere, and are not obligated to compare their offerings against competitors.

This creates a significant implication for borrowers. When approaching a lender directly, a customer may only be presented with one set of products, often the lender’s own, without knowing if more competitive or suitable options exist in the wider market. In contrast, working with a mortgage broker ensures the customer benefits from a broader comparison of lenders, and the assurance that the recommended loan truly aligns with their individual needs.

Ultimately, Best Interests Duty strengthens consumer protection in the mortgage industry, well at least if dealing with a broker for a mortgage. It helps build trust in broker-client relationships and ensures that home loan advice is not only professional, but also transparent, ethical, and tailored to the borrower’s best financial outcome.

In an increasingly complex lending landscape, this makes mortgage brokers an invaluable ally for Australians seeking to make informed, confident decisions about their home loans.
