Can I switch my RIO mortgage to another lender?
13th February 2026
By Simon Carr
A Retirement Interest Only (RIO) mortgage is designed for older homeowners who want to release equity or manage existing debt without having to repay the capital until a defined life event occurs (usually the last borrower’s death or moving into long-term care). While RIO mortgages are long-term products, circumstances often change, leading borrowers to ask: can I switch my RIO mortgage to another lender?
Understanding if I Can Switch My RIO Mortgage to Another Lender
The short answer is yes, you are typically free to switch your Retirement Interest Only (RIO) mortgage provider by remortgaging. This process is standard financial practice, allowing borrowers to seek better rates, more flexible terms, or a different borrowing amount from a new provider.
However, unlike remortgaging a standard residential mortgage at a younger age, switching a RIO mortgage involves a rigorous affordability check by the new lender. Because RIO mortgages are specifically designed for retirees, the core requirement is proving the sustainability of your retirement income to comfortably cover the interest payments for potentially many years.
The Mechanics of Switching Your RIO Mortgage
When you switch your RIO mortgage to a new lender, you are not simply porting the agreement; you are applying for a brand-new mortgage deal. The new lender will assess your financial situation from scratch. This process usually follows several key stages:
- Reviewing Current Terms: The first step is checking if your current RIO deal has any Early Repayment Charges (ERCs) that would apply if you switch now.
- Affordability Assessment: The new lender will rigorously assess your income (pensions, investments, rental income, etc.) to ensure the interest payments remain affordable for the foreseeable future.
- Property Valuation: The new lender will require a valuation of your property to ensure its value meets their lending criteria.
- Legal Completion: Solicitors handle the transfer of the charge from the existing lender to the new one.
It is often advisable to use a specialist mortgage broker who understands the intricacies of RIO mortgages and the specific criteria different lenders apply, especially when dealing with non-standard retirement income streams.
Key Eligibility Criteria When Remortgaging a RIO
Lenders treat RIO remortgage applications cautiously, as they are lending to individuals often relying solely on fixed retirement incomes. The primary concerns revolve around age and sustained income.
1. Sustainable Income Proof
You must demonstrate that your retirement income is sufficient not just now, but also in the long term, to cover the interest payments. Lenders typically apply a “stress test,” assuming potential future interest rate increases, to confirm payments remain affordable.
- Accepted Income Sources: State pensions, private or company pensions, certain investment income, and sometimes assured rental income.
- Lender Variations: Different lenders assess income differently. Some may be stricter regarding income derived from certain investments or annuities.
2. Age and Maximum Term Limits
While RIO mortgages do not have a set end date (they end upon a defined life event), lenders often have maximum ages they will accept applicants up to. If you took out your original RIO at 75, switching lenders at 85 might be more difficult if the new provider has a strict upper age limit for new applications, even for a RIO product.
3. Credit History Requirements
Like any mortgage application, your credit history plays a vital role. The new lender will check your credit report to assess your repayment behaviour and history of debt management. Any defaults or significant missed payments could jeopardise your application.

Costs and Fees Associated with Switching RIO Lenders
While switching lenders can secure you a better interest rate, potentially saving money over time, there are various costs associated with the process that must be budgeted for:
- Early Repayment Charges (ERCs): If you switch before your current fixed or discounted period ends, your existing lender may charge a significant fee, typically calculated as a percentage of the outstanding loan balance.
- Arrangement/Product Fees: The new lender will charge a fee for setting up the new mortgage product. These can often be added to the loan balance, but this means you pay interest on them over the term.
- Valuation Fee: The new lender needs to verify the property value. Sometimes this fee is covered by the lender, but often it is payable by the borrower.
- Legal/Conveyancing Fees: Solicitors are required to handle the legal transfer of the mortgage from one lender to another.
Always calculate whether the savings from the new, lower interest rate outweigh the total cost of these fees.
Advantages of Remortgaging Your RIO
Despite the administrative complexity, there are significant reasons why homeowners look to switch their RIO provider:
Securing a Lower Interest Rate: The most common reason. Moving to a new lender could significantly reduce your monthly interest payments, freeing up essential retirement income.
Accessing Better Products: Mortgage markets change, and new lenders may offer RIO products with features better suited to your needs, such as options for slightly lower initial payments or better withdrawal flexibility (if increasing the borrowing amount).
Consolidating Debt: If your property has increased significantly in value, you might be able to remortgage for a slightly higher amount to pay off existing debts, consolidating them into a single, potentially cheaper, interest payment.
Managing Financial Risk: Moving from a variable rate RIO to a fixed rate RIO with a new lender can provide certainty regarding monthly costs, helping with long-term budgeting in retirement.

Potential Risks If You Cannot Switch Lenders
While many RIO mortgages can be switched, there is a risk that you may fail to meet the new lender’s criteria, particularly if your retirement income has decreased or if the market has tightened since you took out your initial RIO.
If you cannot secure a new deal, you might be forced to remain on your existing lender’s Standard Variable Rate (SVR) once your fixed term ends. SVRs are typically much higher than initial fixed rates, leading to substantially increased monthly payments. This is why planning well in advance of your current deal expiry is essential.
If you find yourself struggling to afford the interest payments, regardless of which lender you are with, your property may be at risk if repayments are not made. Consequences of default can include legal action, additional charges, and, ultimately, repossession.
People also asked
Can I take out more money when I switch my RIO mortgage?
Yes, you can potentially borrow more money, but this is subject to the new lender’s strict affordability checks. You must prove your income can sustain the interest payments on the larger loan amount, and the new total must fit within their Loan-to-Value (LTV) limits.
Is a RIO mortgage the same as an equity release mortgage?
No, they are different. A RIO mortgage requires you to make mandatory interest payments monthly. Equity release (like a Lifetime Mortgage) allows the interest to roll up and be added to the loan balance, meaning no monthly payments are typically required, but the debt grows much faster.
How long does the RIO remortgage process take?
The process generally takes similar time to a standard remortgage, typically 6 to 12 weeks from application to completion. However, securing the necessary proof of retirement income and legal checks can sometimes take longer, especially if specific legal documentation regarding future estate planning is required.
What happens if one borrower dies on a RIO mortgage?
If the RIO mortgage is held jointly, the mortgage typically continues for the surviving borrower. The surviving borrower must still meet the ongoing affordability criteria to prove they can continue making the interest payments alone. If they cannot, the terms of the mortgage may require the property to be sold.
Is it harder to get a RIO mortgage now than it was five years ago?
Lending criteria fluctuate based on the economic environment and regulation. While RIO products have matured, lenders have become stricter regarding the affordability stress testing applied to retirement incomes to ensure long-term sustainability, especially amidst rising inflation and interest rates.
Conclusion
Switching your Retirement Interest Only mortgage to another lender is a feasible and potentially financially beneficial strategy if you are looking to secure a lower interest rate or better terms. However, success hinges entirely on your ability to satisfy the new lender’s current and long-term affordability requirements based on your specific retirement income. Due to the complex nature of retirement lending, consulting an independent financial adviser or specialist mortgage broker is highly recommended before starting the switching process.
