Should You Refinance Your Home Loan With the Same Bank or Switch Lenders? (2026)
The cheapest fix for a stale home loan rate is a conversation with the bank you already use. The market decides whether that fix goes far enough.
Ask your current lender to reprice the loan first: it costs nothing, usually involves no new application, and often closes most of the gap. Then hold the result against the wider market. Switch lenders when the remaining gap keeps compounding, when your bank will not move, or when the loan itself no longer fits.
- Three paths, not two. Reprice with your current lender (a better rate on the loan you already have), switch products with the same lender, or switch banks entirely (a full refinance). Effort, paperwork and cost rise with each step, and repricing costs nothing to try.
- Banks cut rates for customers who ask. Keeping a performing loan at a thinner margin is usually cheaper for a lender than paying to replace the customer. Retention pricing exists for exactly this conversation.
- The loyalty tax is documented. The ACCC’s Home Loan Price Inquiry found the longer a variable loan sits untouched, the wider the average gap grows between what its borrower pays and what new borrowers pay.
- Sometimes staying put wins. If a repricing request closes most of the gap, the cheapest refinance is the one you never do, and an honest broker says so.
What are your options when your home loan rate looks stale?
Stay or switch is the usual framing. In practice there are three paths, and the cheapest is the one almost nobody writes about. Repricing means asking your current lender to sharpen the rate on the loan you already have; nothing else changes. A product switch keeps you with the same bank but moves you to a different loan: a packaged loan to a basic one, variable to fixed, adding or dropping an offset. A full switch is what most people mean by refinancing: a new lender assesses you, pays out the old loan and registers a new mortgage.
Commercial loan? The same decision has different mechanics: see the commercial version of this guide.
| Dimension | Reprice with your current lender | Switch products, same lender | Switch to another lender |
|---|---|---|---|
| What it is | A better rate on the existing loan, which stays in place | A different loan product with the bank you already use | A new lender pays out the old loan and registers a new mortgage |
| Effort | One conversation, strongest with evidence prepared | A short internal process, without shopping the market | A full application plus comparison across lenders, usually broker-run |
| Paperwork | Usually none; the bank holds your file | Minimal; sometimes a form and a product switch fee | The incoming lender’s requirements: identity, income, statements |
| Costs usually triggered | Usually none | Possible switch fee; no discharge, no new registration | Discharge fee, government registration fees, sometimes valuation and application fees, and break costs on a fixed rate |
| What can change | The rate, and sometimes ongoing fees | Product, features such as offset and redraw, fixed or variable structure | Everything: lender, pricing, features, structure and credit policy |
| What cannot change | The lender, the product and the credit policy all stay | You are still confined to one lender’s pricing and appetite | Nothing structural, but switching costs and effort cannot be avoided |
| When it typically wins | The rate has drifted but the loan otherwise fits, and conduct is clean | You want different features and your bank remains competitive | The gap stays wide after repricing, the bank will not move, or the loan no longer fits |
On a fixed rate, a full switch can trigger break costs, and only your lender can quote the exact figure. Our guide to home loan break costs explains how the number is built and how to get it before you decide anything.
Why would your bank cut your rate just because you asked?
Because keeping you is usually cheaper than replacing you. A new customer costs a bank marketing, assessment and settlement work before the first repayment arrives; a retained customer costs only a thinner margin. For a well-conducted loan, agreeing to a repricing request is often the cheapest decision on the desk.
Retention economics are not sentimental, they are arithmetic. When a performing home loan walks out the door, the bank loses a reliable income stream and then pays to replace it: winning a new borrower, assessing a new file, carrying the risk the new loan behaves worse than the one it lost. Accepting a slightly thinner margin on a loan the bank already knows is the quieter, cheaper decision, which is why retention pricing exists at all.
Everstone’s founders, Ahmed Lotfi and Zappelin Heng, are former bankers who spent years inside major banks before broking. From that side of the desk the pattern was consistent: the sharpest pricing energy went to winning new customers while the existing book quietly drifted, and the customers who asked, with evidence in hand, were the ones whose files were escalated and repriced. Every bank runs its own playbook and policies change over time, so treat that as history rather than a promise about your lender. The economics that produced it have not changed.
The corollary is that pricing attention flows to customers who ask. No lender is obliged to volunteer its sharpest pricing to a quiet customer, and most do not. This page settles whether repricing or switching is the right move; when the answer is reprice, the repricing playbook, scripted walks through the how: what to prepare, what to actually say, and how to read the offer that comes back.
When does switching beat repricing?
Switching wins when the gap between your repriced rate and the market stays wide, when your bank will not move, or when you need something it cannot offer: different features, a different structure, or credit policy that suits your income and property. A retention offer can only ever be one lender’s best.
Repricing has a ceiling: your bank’s own book. However hard you push, a retention offer can only reach the sharpest pricing that one lender is prepared to write, and lenders differ on the same file more than most borrowers expect. One treats your overtime or bonus income generously, another discounts it. One is comfortable with your suburb, your apartment size or your self-employment history, another prices the caution in. If your loan sits with the wrong lender for your circumstances, no negotiation closes the gap, because the gap is policy, not attitude.
Switching is also the answer when the problem is structural rather than price: a bank whose offset account is not a true offset, a product that cannot split the loan the way your plans need, or a lender that has quietly stopped competing for loans like yours. And switching is the only path that puts the whole market’s pricing on the table at once, which is exactly the comparison a repricing request is measured against.
The honest caveat: switching triggers real costs. A discharge fee from the outgoing lender, government fees to deregister and register the mortgage, sometimes valuation or application costs at the incoming lender, and break costs if any part of the loan is fixed. The saving has to clear those costs before it is a saving at all, which is why the comparison must run both ways: what the switch wins, and what the reprice would have captured for nothing.
Which signals say reprice, and which say switch?
Reprice first when the rate has drifted but the loan still fits: clean repayment history, workable features, a structure you would choose again. Switch when the bank will not move or cannot help: a wide gap that survives the retention offer, features or policy outside its book, or problems that go beyond price.
Signals you should reprice first
- The rate has drifted but the loan otherwise fits. The features, the structure and the service still work; only the price is stale.
- Your repayment history is clean. A well-conducted loan is the one a retention team fights to keep, so your leverage is at its peak.
- Part of your loan is fixed. Ask your lender for the break cost figure before anyone talks you into moving; repricing the variable portion, or waiting out the fixed term, may be the only free move right now.
- You have never asked. If the loan has never been repriced, the first conversation is the cheapest experiment in home finance.
Signals you should switch
- The bank offered a token cut, or nothing. A retention offer that leaves a wide gap to the market is a priced decision; treat it as your answer.
- You need something the bank will not do. A true offset account, a different split, or credit policy that treats your income or your property type properly.
- Your equity has grown and your pricing does not reflect it. A loan that has drifted below the loan to value thresholds lenders price against can be worth more to the market than to the bank that wrote it.
- A cashback would genuinely clear your switching costs. Run the honest maths first: our guide to refinance cashback offers shows where the fine print bites.
- The problems go beyond price. Slow service, unworkable processes, or a product that no longer fits the way you live.
The loyalty tax: what the ACCC actually found
The loyalty tax is the documented pattern of long-standing borrowers drifting onto worse pricing than new customers at the same lender. It is not a slogan: the ACCC’s Home Loan Price Inquiry measured it on Australian residential home loans and found the gap widens the older a loan gets.
The pattern has a name and a paper trail. In October 2019 the federal Treasurer directed the Australian Competition and Consumer Commission to examine home loan pricing: what lenders were charging, and what stops borrowers from switching. That work became the Home Loan Price Inquiry, and its final report went to the Treasurer in November 2020. This was a residential inquiry, about exactly the kind of loan on your kitchen table.
The finding that matters here: the longer a variable rate loan sits untouched, the wider the average gap grows between what its borrower pays and what borrowers with new loans pay. The final report put numbers on it, measured in basis points, where one basis point is one hundredth of a percentage point.
The final report also documented why the gap survives. Switching involves a discharge process the inquiry found could be harder and slower than it needs to be, and borrowers with older loans rarely receive a compelling prompt to look at the market. Its conclusion is the entire thesis of this page: many borrowers could make significant savings by switching lenders, or by negotiating with their existing lender for pricing closer to what new customers are offered. Both cures start the same way, with one question to your bank.
The break-even test
Strip away the noise and the switch decision is one division. Add up what the move would cost: the discharge fee, government registration fees, any application or valuation costs, and break costs if any part of the loan is fixed. Divide that total by the monthly saving the new loan delivers. The answer is the number of months the refinance takes to pay for itself. Under a year is usually compelling; several years is a signal to reprice and stay.
If you want the whole journey in one place, our guide to refinancing in plain English walks it end to end, and the refinance savings calculator lets you run the division with your own numbers. If the question on your mind is not whether but when, our guide on when to refinance your home loan covers the triggers and the cadence.
According to Everstone Finance, whose founders worked inside major banks before broking, the cheapest refinance is often not a refinance at all: a repricing request to your current lender costs nothing and needs no new application, and switching only earns its paperwork when the gap the retention desk will not close keeps compounding every month.
Frequently asked questions
What is the difference between repricing and refinancing a home loan?
Repricing means asking your current lender for a better rate on the loan you already have: no new loan, no discharge, usually no paperwork. Refinancing means replacing the loan, either with a different product at the same bank or a new loan at another lender. Repricing changes the price; refinancing can change the price, the features and the lender.
Does asking my bank for a lower rate affect my credit score?
A repricing request is not a credit application, so it does not typically add an enquiry to your credit report. Refinancing to a new lender involves a full application, and credit applications are recorded on your file. If you are unsure how a request will be treated, ask the lender before anything is lodged.
Can my bank refuse to lower my rate?
Yes. Repricing is discretionary, and no lender is obliged to sharpen a rate for an existing customer. A refusal usually means the bank has priced the risk of losing you and accepted it, which is useful information in itself: it tells you the remaining gap can only be closed by switching.
Do I have to switch banks to refinance?
No. You can refinance internally by moving to a different product with your current lender, which avoids discharge and registration costs but keeps you inside one bank’s pricing and policy. A full refinance to another lender opens the whole market, at the cost of a new application and switching fees.
How often should I check whether my home loan is still competitive?
Review the loan about once a year, and again whenever a fixed period is ending or your circumstances change. A yearly check costs one conversation, and the ACCC’s home loan pricing inquiry found the gap between what older loans and new loans pay tends to widen the longer a loan is left alone.
Is it worth switching lenders for a small rate difference?
Sometimes. Even a modest difference compounds on a large balance over a long term, but switching triggers real costs, so the saving has to clear them. Run the break-even test: divide the total cost of switching by the monthly saving. If the answer lands under a year, the move usually earns its paperwork; if not, a reprice may capture most of the benefit at no cost.
The honest summary
The order of operations is the whole answer. Ask your current bank to reprice first, because it costs nothing and usually needs no application, and measure the offer against what the wider market would write for your file. If the bank closes the gap, you have fixed the loan without touching it. If the gap stays wide, if the answer is no, or if the loan no longer fits the way you live, switching is not disloyalty, it is arithmetic, and the loyalty tax the ACCC measured is what the arithmetic looks like when nobody runs it. Everstone runs both sides of that comparison and tells you honestly which one your file supports.
