Not necessarily, and there’s no rule that says you have to. Keeping everything with one bank can make life simpler, but it doesn’t always get you the best deal. The right answer depends on what you value more: convenience, or getting each loan priced on its own merits.
Here’s the thing
Banks love it when you bundle. More products with one lender often means a “relationship discount”, a single login, one statement to read, and one phone number to call when something needs fixing. For a lot of people, that’s genuinely worth something. Less admin, less chasing, fewer passwords.
But that convenience has a cost, and it’s worth knowing what it is before you sign up.
What you actually give up by bundling
You can lose negotiating power. When everything sits with one lender, you’ve got nothing to compare it against. Lenders price more competitively when they know you’re shopping around. Split your loans and you keep a benchmark in your back pocket.
One shaky patch can ripple across everything. If your relationship with that lender sours, whether that’s a rate that creeps up, a policy change, or a service issue, it affects every product you hold with them at once. Spread across two or three lenders, a problem with one doesn’t touch the others.
You might be paying for convenience, not value. “Relationship discounts” aren’t always as generous as they sound. Sometimes a competing lender’s standalone rate beats the bundled rate once you actually run the numbers.
What you gain by spreading your loans around
Splitting loans across lenders means each one gets assessed and priced on its own. Your home loan can go to whoever has the sharpest residential rate this quarter, and your car loan can go to whoever specialises in that. You’re not locked into mediocre terms just because it’s easier to log into one app.
The credit score question
A fair concern, and a fair one to raise. Every time you apply for credit, the lender runs a hard enquiry, and a flurry of enquiries close together can dent your credit score for a little while. That’s true whether you’re applying with one lender for three products or three lenders for one each.
The fix isn’t “stick with one bank to be safe.” It’s “don’t apply for everything at once.” Space applications out, and get a broker to assess your borrowing position properly before you submit anything; that’s exactly the kind of upfront work that avoids unnecessary hits to your file.
So which is right for you?
If you genuinely value simplicity and the bundled rate stacks up against the market, one lender can work fine. If you’re chasing the sharpest rate on each individual product, or you want some insulation if one relationship goes sideways, spreading them out is usually the stronger play.
There isn’t a universal right answer here, and that’s completely okay. What matters is that the decision is made on purpose, not by default because it was the path of least resistance.
FAQs
Will applying for loans with multiple lenders hurt my credit score?
A single credit enquiry has a small, temporary impact. The risk comes from applying for several products in a short window. Spacing applications out, or getting pre-assessed first, avoids this.
Is a “relationship discount” usually worth it?
Sometimes. It depends on the lender and the products. The only way to know is to compare the bundled rate against what each product would cost standalone elsewhere.
Can a broker help me work out whether to bundle or split?
Yes, that’s exactly the kind of comparison a broker runs for you, across lenders, without you needing to apply everywhere yourself to find out.
