Many homeowners over 55 assume that once their income falls after retirement, switching to a new mortgage lender is off the table. Recent changes across the mortgage industry have made that much less true — with the number of lenders offering a more flexible approach to remortgage assessments growing from 8 to 121 in just over a year. Here is what has changed and who it could help.
When a homeowner takes out a mortgage, the lender assesses their income at that point — usually based on employment, salary, and documented earnings. If, a few years later, that person retires or reduces their working hours, their income profile changes significantly. Pension income, drawdown arrangements, and state pension payments typically look very different from the employment income on which the original mortgage was based.
When that borrower tries to switch to a new lender — perhaps because their current deal has expired and the rate on offer is uncompetitive — the new lender runs its own affordability assessment. If that assessment applies the same employment-income model to a retiree’s income sources, it can produce a lower maximum loan than the existing mortgage, or decline the application entirely. The result is that many over-55 borrowers have felt stuck: unable to move to a better deal elsewhere and forced to accept whatever their existing lender offers, even when that rate is significantly above what is available in the broader market.
Since mid-2025, mortgage industry practices have shifted substantially in this area. Rather than always requiring a full affordability reassessment when a borrower wants to switch lenders, a growing number of lenders now use a more straightforward approach: they verify that the borrower has been meeting their existing mortgage payments consistently and assess whether the new deal is affordable on a continuation basis, rather than treating the remortgage as if the borrower were a first-time applicant with no track record.
Research from Stonebridge covering the period following these changes shows the scale of the shift. The number of lenders offering this modified assessment approach grew from 8 to 121 between mid-2024 and mid-2025. The proportion of borrowers able to move to a new lender using this route rose from 88% to 98%. And in Q1 2026, remortgages that used a modified assessment to stay with the existing lender fell 82% year-on-year — a sign that borrowers are now shopping around and finding competitive options with new lenders, rather than defaulting to their current provider out of necessity.
The practical benefit is greatest for homeowners whose income has changed since they originally took out their mortgage — which describes a large proportion of people in their late 50s, 60s, and 70s who are managing the transition from employment income to retirement income. If a borrower has a clean repayment history, sufficient equity in their property, and an existing mortgage they have been servicing without difficulty, the modified assessment approach allows a new lender to assess those facts rather than requiring the borrower to meet an employment-income test they no longer fit.
It is also relevant to homeowners who had previously been told that switching was not possible, or who assumed it was not worth trying because of earlier experiences. The market has changed significantly since 2023 and 2024, and an assessment carried out then may not reflect what is currently available.
The option to remortgage to a new lender using a modified assessment is separate from dedicated later-life lending products — retirement interest-only (RIO) mortgages and lifetime mortgages — which are designed specifically for older borrowers and remain the most appropriate route for many people.
A RIO mortgage requires interest to be paid monthly but has no fixed end date, with the capital repaid when the property is sold or the borrower moves into care. A lifetime mortgage rolls up interest (or allows voluntary payments) over the borrower’s lifetime, with no monthly obligation. Both products have specific eligibility criteria and long-term implications that a standard remortgage does not carry.
For some over-55 borrowers, the modified assessment remortgage route will offer the best combination of rate and flexibility. For others, a RIO or lifetime mortgage will be more suitable. The two options are not mutually exclusive to consider — they are different tools, and the right one depends on income, equity, age, and what the homeowner is trying to achieve. Speaking to a whole-of-market specialist who covers both areas is the clearest way to understand which route fits a particular situation.
“The assumption that you cannot move lender once your income changes in retirement has become far less accurate. It is worth checking what is now available before concluding that you are stuck.”
