Mortgage Broker vs Going Direct to a Bank

A bank lends its own money against its own products. A mortgage broker lends nothing — the broker is a credit adviser who compares loans across a panel of lenders and arranges the application you choose to proceed with. That single distinction shapes everything else. When you walk into a branch, the person across the desk works for that bank and can only offer that bank’s loans, assessed against that bank’s policy. When you sit with a broker, you are looking at a field of lenders through one point of contact.

Neither channel is automatically better. A bank knows its own products intimately and, for an existing customer, already holds your history. A broker sees across the market but cannot reach into any one lender’s internal retention pricing. The right question is not “which is better in the abstract” but “which suits this borrower, this property and this moment” — and that depends on your circumstances and the lender’s assessment.

A broker’s work is comparison and coordination. The broker assesses your borrowing position — income, deposit or equity, existing commitments, credit conduct, the property and your goals — and matches that against each lender’s policy. Lender policy varies far more than most borrowers expect: how income is read, how existing debts and living expenses are treated, which property types are acceptable, and how high a loan-to-value ratio each lender will go to. The broker shortlists the lenders whose policy fits your situation, explains the trade-offs, and manages the application through to settlement.

• Comparing loans across a panel of lenders against your specific position
• Explaining structure — fixed versus variable, offset, redraw, splits — not just the rate
• Preparing and submitting the application and responding to lender queries
• Working within responsible-lending obligations and, in residential lending, the best interests duty

What the broker does not do is decide your loan. Any approval depends on the lender’s assessment, its lending criteria and your circumstances. Our broking work is set out across our finance and mortgage services, and the document list for getting application-ready is covered on our pre-approval page.

Applying directly means dealing with one lender and its single product set. For a straightforward borrower — salaried income, a clean deposit, a standard property — this can be simple and quick, especially with a bank you already use, because it can see your accounts and history. Banks also sometimes offer direct-channel or retention pricing that is not available through the broker channel, which is worth knowing if you are an existing customer asking to stay.

The limitation is scope. A single bank assesses you against its own policy only. If your income shape, the property type or your serviceability sits awkwardly against that one lender’s rules, a direct decline tells you little about whether another lender would have said yes. You would then start again elsewhere. A direct application is a depth-first approach to one lender; a broker is breadth-first across several. Which suits you depends on how standard your situation is.

A bank earns from the interest and fees on the loan it writes. A broker, in most residential lending scenarios, is paid commission by the lender on settlement — typically an upfront commission and an ongoing trail while the loan remains active. There is generally no separate fee charged to the borrower for residential credit assistance, though some specialist or complex transactions can involve a fee-for-service arrangement, which is disclosed in writing before you commit.

Because lenders pay different commission rates, the broker channel carries a potential conflict of interest, and that is managed by disclosure and by the best interests duty: the recommendation must be in your interests regardless of commission, and the reasoning is documented. We explain exactly how we are paid, the lender panel and any conflicts in our Credit Guide and Credit Proposal Disclosure before any application is submitted. Transparency about remuneration is the standard either way — ask any lender or broker to set it out in writing.

A broker tends to add the most where lender variation is large. Self-employed borrowers, company and trust owners, investors with several properties, borrowers with a tight serviceability position, and unusual property types all read very differently across the panel — the same set of figures can produce materially different borrowing capacities depending on which lender assesses them. Matching the right lender to those circumstances is where comparison earns its keep.

A broker adds less where the situation is genuinely standard and you already have a competitive position with your bank. If a salaried borrower with a clean file is happy with their lender’s offer, the broker’s contribution is mainly comparison and handling the process rather than a different outcome. Being honest about this matters: a broker is not a guarantee of a lower rate or a better deal, and any approval still depends on the lender. What a broker reliably offers is breadth of comparison and someone to manage the application end to end.

Start with how standard your situation is and how much you value comparison versus a direct relationship. If your income is simple, your deposit is clean and your current bank is competitive, a direct application may be all you need. If your income shape is complex, your serviceability is tight, the property is unusual, or you simply want the field compared and the process handled, a broker is likely worth the conversation. A sensible review often looks at your current lender alongside the panel rather than treating either channel as automatically better.

For borrowers whose tax position drives their borrowing — the self-employed especially — there is a further consideration: having the accountant who prepares the figures also arrange the loan keeps both sides consistent. We explain how that combined role works in our guide to what an accountant and mortgage broker actually do, and you can start a no-obligation conversation any time by getting in touch. We will tell you honestly where a broker helps and where a direct application would serve you just as well.

This guide is general information only and does not take into account your objectives, financial situation or needs. It is not credit advice. Any loan approval depends on the lender’s assessment, the lender’s lending criteria and your individual circumstances. We explain how we are paid in our Credit Guide before any application is submitted.
