The following are a few reasons why home loan customers are satisfied with their banks:
- “I have been with ING through 2 mortgages and savings accelerator accounts. their rates are always competitive, and the customer service is always good” & “App is good. No scandals as far as I know. Had the best mortgage rates when we were looking for one” – ING Home Loan Customers.
- “Their offset accounts against mortgage loans are a great feature. Being able to have multiple offset accounts to manage our money well is useful and helpful” and “When I divorced; I went through a property settlement and looked for a home loan. Suncorp was the only one that would lend me the money” – Suncorp Loan Customers.
- “Bendigo Bank has best home loan rates around mortgage under $250,000 dollars” & “Their loan was competitive” - Bendigo Bank Home Loan Customers.
- “Easy application of a Mortgage and online platforms are easy to use and understand” & “Since joining them two years ago; after being recommended by a broker, I have been very satisfied with the products they offer, up to 10 offset accounts to the mortgage account” – Macquarie Home Loan Customers.
- “They were most helpful when it comes to getting a home loan and have been easy to deal with since and have given suggestions that better suit my situation instead of being greedy and ripping me off” & “I just know there are banks with better interest rates however they were really good when getting my home loan and would finance a lot of apartments I was looking at” – NAB Home Loan Customers.
Roy Morgan CEO Michele Levine says ING has maintained an outstanding level of home loan customer satisfaction over the last year and increased its satisfaction from a market leading 91.2% a year ago to 92.1% in May 2026:
“Home loan customer satisfaction for Australia’s top banks was at 78.3% in the six months to May 2026, up 4.2% points from a year ago (74.1%). The increase is despite interest rates in May 2026 (4.35%) being 0.5% points higher than a year ago in May 2025 (3.85%).
“During the pandemic the peak for home loan customer satisfaction across the top banks was in the six months to February 2021 at 80.2%. This mark was not exceeded until home loan customer satisfaction reached a post-pandemic peak of 81.1% in the six months to December 2025 after three interest rate cuts during 2025 which dropped official interest rates to 3.6%.
“However, early indications from the latest monthly data are that the three interest rate increases in the first half of 2026 are starting to have an impact on home loan customer satisfaction which is slightly below the peak reached in the six months to December 2025. The interest rate increase of +0.25% to 4.35% in May means interest rates are now at their equal highest in almost 15 years.
“Because of the way interest rates operate in the economy it takes up to two years to see the full impact of an official interest rate increase. Given this time lag we are still yet to see the full impact of the current cycle of increases which will continue to hit households throughout this year as home loan repayments reset to higher levels.
“Looking at the banks, ING has excelled during the last year with the highest home loan customer satisfaction at 92.1%, up 0.9% points from a year ago, ahead of the ANZ owned Suncorp Bank (87.1%, up 2.3% points), Bendigo Bank (84.1%, up 1.6% points) and Macquarie (79.7%, up 0.4% points).
“The big four banks have performed well over the last year with the largest increases in home loan customer satisfaction led by NAB on 78.8% (up 6.5% points), ahead of the Commonwealth Bank on 78.7% (up 3.6% points), ANZ on 75.6% (up 6.1% points), and Westpac on 74.2% (up 2.8% points).”

Margin of Error
The margin of error to be allowed for in any estimate depends mainly on the number of interviews on which it is based. Margin of error gives indications of the likely range within which estimates would be 95% likely to fall, expressed as the number of percentage points above or below the actual estimate. Allowance for design effects (such as stratification and weighting) should be made as appropriate.
