Can I extend the term of my RIO mortgage?

13th February 2026

By Simon Carr

A Retirement Interest Only (RIO) mortgage is designed to run either until a specific fixed date or until a defined life event occurs, usually the last borrower’s death or moving into long-term care. Extending the term of an existing RIO mortgage is complex and typically requires a complete re-evaluation by the lender, as the continued affordability of interest payments must be proven for the duration of the requested extension.

Understanding if and how can I extend the term of my RIO mortgage?

Retirement Interest Only (RIO) mortgages offer a financial solution for older homeowners, allowing them to release equity or manage existing debt without having to repay the capital until a defined future event. However, unlike traditional capital repayment mortgages that might be easily extended during the term, the structure and regulation surrounding RIO products mean that adjusting the term involves significant scrutiny.

How RIO Mortgage Terms are Defined

To understand the feasibility of extending your RIO mortgage, you must first understand how its term was initially set. RIO mortgages generally fall into two categories:

  • Event-Based Term: The vast majority of RIO mortgages are structured to run until the death of the last surviving borrower or when the last borrower moves into permanent care. In this scenario, there is no fixed ‘term’ to extend, as the mechanism for repayment (the sale of the property) is tied to a life event.
  • Fixed Term with Maturity Date: Less common, but still offered by some providers, is an RIO mortgage with a strict contractual maturity date (e.g., age 90 or 95). If you are approaching this hard maturity date, you are effectively asking for an extension beyond the lender’s internal policy limits.

If your RIO is event-based, the question of ‘extension’ is generally irrelevant, as the mortgage is already designed to last the rest of your life in your current home. However, if your mortgage has a hard maturity date and you are approaching it, extending the term becomes a serious application process.

The Challenges of Extending a Fixed-Term RIO

When you ask to extend the term of a regulated secured loan like a RIO mortgage, the lender is legally required to treat this request as a new lending decision. This triggers mandatory compliance and affordability checks designed to protect both the consumer and the lender.

1. Re-assessment of Affordability

The core compliance requirement for RIO mortgages is proving that the borrower can afford the interest payments for the entirety of the loan term. Extending the term means the lender must re-verify that your retirement income (pensions, investments, benefits) is sustainable and adequate to cover the interest payments for the additional years requested.

If your income profile has changed since the original application, or if the lender’s interest rates have increased, this check may prove challenging. Lenders use strict criteria to stress-test affordability, ensuring you can cope if interest rates rise further.

2. Maximum Age Limits

Every RIO lender sets a maximum age limit for the end of the mortgage term. For many, this limit is typically between 85 and 95. If extending the term means pushing the loan maturity date past the lender’s maximum policy age, the extension will likely be declined. You may need to explore remortgaging to a different lender with higher maximum age limits.

3. Valuation and Equity Requirements

Although RIO mortgages are interest-only, the lender must be confident that the property value will remain sufficient to repay the capital upon sale. An extension may trigger a new valuation. If local property values have fallen, or if the loan-to-value (LTV) ratio is approaching the lender’s threshold, they may be hesitant to extend the commitment without a capital repayment.

The Process for Requesting a RIO Term Extension

If your RIO mortgage has a fixed maturity date that is approaching, you should start the discussion with your current lender early—ideally 6 to 12 months before maturity. The process generally involves the following steps:

  1. Initial Contact: Contact your lender’s mortgage administration team to explain your situation and formally request a term extension.
  2. Information Gathering: The lender will request updated documentation, including evidence of all current retirement income, bank statements, and details of any change in financial circumstances.
  3. Credit Assessment: A full credit search is typically required. Maintaining a strong, clean credit file is essential for any mortgage extension or product transfer application.
  4. Underwriting Review: The lender’s underwriters will assess your request against current lending criteria, focusing heavily on whether your income can sustainably cover the interest payments for the new, longer term.
  5. Decision and Fees: If approved, you will be offered new terms, which may involve arrangement fees, valuation fees, and legal costs. You should review these costs carefully against the potential benefit of the extension.

To prepare for the affordability assessment, it is prudent to review your own credit report beforehand to identify and resolve any discrepancies.

What If My Lender Declines the Extension?

If your current lender refuses to extend the RIO term, usually due to affordability concerns or exceeding their maximum age policy, you still have several viable alternatives to ensure you do not default when the mortgage matures.

Remortgaging to a New Provider

You may be able to find a different RIO provider in the market that offers more flexible criteria, higher maximum age limits, or better rates that improve your affordability metrics. Engaging a specialist mortgage broker who understands the nuances of the later-life lending market is highly advisable here.

Switching to Equity Release

If ongoing interest payments are the main barrier to affordability, or if you are already past the age limit for RIO mortgages, you may consider a Lifetime Mortgage, which is the most common form of equity release.

  • How it differs: With a Lifetime Mortgage, the interest is typically ‘rolled up’ and added to the loan balance, meaning you make no mandatory monthly payments (though you can often opt to pay some interest voluntarily).
  • Considerations: Equity release reduces the inheritance value of your property and the debt can grow quickly due to compounding interest. However, it removes the need to prove ongoing income affordability.

Downsizing

If all other lending options are exhausted, downsizing—selling your current property and purchasing a smaller, less expensive home—allows you to use the sale proceeds to clear the existing RIO mortgage debt and potentially buy the new property outright, eliminating all future mortgage concerns.

Compliance and Risks Associated with RIO Mortgages

Whether you extend the term or remortgage, it is vital to remember the fundamental nature of the loan. A RIO mortgage is a secured loan, meaning that any failure to maintain the interest payments puts your home at risk.

If repayments are not made, the consequences can include legal action, additional charges, increased interest rates, and, ultimately, repossession of the property.

Your property may be at risk if repayments are not made.

People also asked

Can I switch from an RIO mortgage to standard interest-only?

Switching from an RIO back to a standard interest-only mortgage is difficult in later life. Standard interest-only mortgages typically have much stricter maximum age limits (often 75 or 80) and require a robust, verifiable repayment strategy for the capital that the RIO structure does not demand.

What happens if I cannot pay the interest on my RIO mortgage?

If you fail to make required monthly interest payments, your RIO mortgage is considered in default. The lender will begin a formal collections process. Persistent failure to pay interest could lead to the lender seeking possession of the property to recover the outstanding loan amount.

Is there a maximum LTV for RIO mortgages?

Yes, RIO mortgages typically have stricter Loan-to-Value (LTV) limits than standard mortgages, usually ranging between 50% and 60% of the property value. If you extend the term, the lender will check that your LTV still falls within their acceptable range based on the current property valuation.

Do I have to take financial advice to extend my RIO?

While not legally mandatory simply to ask for an extension, it is highly recommended. Because RIO mortgages are complex, specialist financial advice ensures that extending the term is the best course of action for your long-term retirement planning and that you fully understand the implications of the revised contract.

Does the interest rate change if I extend the RIO term?

If you are granted an extension, it is highly likely that your interest rate will change. The lender will either move you onto their current Standard Variable Rate (SVR) or offer you a new fixed or tracker product based on market rates available at the time of the extension approval.

Conclusion on RIO Term Extensions

Extending the term of a RIO mortgage is a highly specific process determined by whether your original agreement was event-based or fixed-term. If you require an extension past a fixed maturity date, prepare for a rigorous re-underwriting process focusing on sustainable affordability into extreme old age. By planning ahead, gathering necessary documentation, and considering all available alternatives, you can manage the future of your secured loan successfully.
