Can I repay a Retirement Interest Only mortgage early?

13th February 2026

By Simon Carr

A Retirement Interest Only (RIO) mortgage is designed for the long term, typically running until a defined life event (such as the sale of the property, moving into long-term care, or death). However, borrowers often find themselves in a position where they wish or need to repay the outstanding capital earlier than planned. While it is certainly possible to pay off a RIO mortgage ahead of schedule, doing so almost always involves significant costs, primarily in the form of Early Repayment Charges (ERCs).

Can I Repay a Retirement Interest Only Mortgage Early? Understanding the Costs and Process

For many older homeowners, Retirement Interest Only (RIO) mortgages offer a practical way to manage property wealth in later life. Unlike traditional mortgages, RIOs only require you to pay the interest each month, with the capital debt remaining until a specific life event occurs. However, life circumstances change, and you might find yourself considering an early settlement.

The short answer is yes, you maintain the right to repay the balance of your mortgage at any time. The central consideration is not whether it is possible, but rather the financial consequences attached to the early redemption.

Understanding Retirement Interest Only Mortgages

A RIO mortgage is designed specifically for people over a certain age (typically 55 or 60). It differs fundamentally from standard residential mortgages and certain types of equity release:

  • Interest Payments: You are required to make monthly interest payments throughout the mortgage term. This ensures the debt does not grow.
  • Capital Repayment: The capital borrowed is only repaid when the property is sold. This usually happens when the last surviving borrower either dies, moves into permanent residential care, or decides to downsize.
  • Affordability Checks: RIO lenders must conduct rigorous affordability checks to ensure you can comfortably afford the interest payments for the rest of your expected life.

Because the lender anticipates the loan running for a potentially long, but indefinite, period, most RIO products come with initial fixed-rate periods. It is during these initial periods that repaying the loan becomes most costly.

The Core Cost: Early Repayment Charges (ERCs)

The single largest hurdle when considering how you can i repay a retirement interest only mortgage early is the Early Repayment Charge (ERC). These fees are contractual penalties charged by the lender to recoup interest income they expected to receive, particularly if you pay off the loan during a fixed or introductory interest rate period.

ERCs exist because when a lender offers you a preferential rate (like a 5-year fixed rate), they have planned their own finances and funding costs based on the assumption that your money will stay invested for that duration. If you pull the money out early, they charge a fee to mitigate their loss.

How Early Repayment Charges are Structured

The calculation of the ERC will be clearly outlined in your original mortgage offer document. While structures vary between lenders, they typically follow a stepped or tiered system:

  • Percentage of Outstanding Balance: The ERC is usually calculated as a percentage of the total amount you are repaying.
  • Stepped Scale: This percentage usually decreases year by year within the initial period. For example:
    • Repaying in Year 1: 5% charge
    • Repaying in Year 2: 4% charge
    • Repaying in Year 3: 3% charge
    • Repaying after Year 5: 0% charge (or a nominal exit fee)
  • Maximum Duration: Most RIO ERCs last between five and ten years. Once you are outside this contractual period, you can repay the mortgage entirely without incurring the ERC.

If you have £150,000 outstanding and you are still in a 5% ERC window, the charge alone would be £7,500. This is a crucial figure to factor into your financial planning.

The Process of Early Repayment

If you have decided that the financial benefits of paying off the debt outweigh the cost of the ERCs, you need to follow a clear procedural path with your lender.

1. Contact Your Lender

Your first step must be to formally contact your RIO provider (or their mortgage administration department) to inform them of your intention to redeem the loan early. This request should be made in writing, detailing the specific date you intend to pay the balance.

2. Request a Settlement Figure

The lender will then issue an official document called a “settlement statement” or “redemption statement.” This document is legally binding and valid only for a short period (usually 7–10 days, depending on the lender). The statement will include:

  • The remaining mortgage capital outstanding.
  • Any accrued daily interest up to the redemption date.
  • The total calculated Early Repayment Charge (ERC).
  • Any unpaid fees or administration charges.
  • The total sum required to fully clear the debt.

3. Securing the Funds

You must ensure the funds are ready by the specified date. Common sources of funds used to repay RIOs early include:

  • Proceeds from downsizing or selling a property.
  • Inheritance or other substantial lump sums.
  • A refinance or switch to a cheaper product (though refinancing might incur its own fees and checks).

4. Legal and Administrative Steps

In most cases, early repayment will require the involvement of a solicitor, especially if the funds are being drawn from the sale of the property. The solicitor ensures the correct funds are transferred to the lender on the redemption date, and that the charge registered against your property at the Land Registry is officially removed.

Other Potential Costs and Fees

While the ERC is the main cost, it is not the only fee you may face:

  • Exit/Completion Fee: Some lenders charge a small, fixed administration fee (typically £50–£300) when a mortgage is concluded, regardless of whether it is repaid early or at the expected maturity.
  • Legal Fees: If you use a conveyancer or solicitor to handle the transaction, their fees will apply.
  • Valuation Fees: If you are repaying the RIO by switching to a new mortgage product with a different provider, the new lender will require a new property valuation, which you usually pay for.

When Does Early Repayment Make Financial Sense?

Paying ERCs is rarely beneficial unless the financial advantage gained by repaying the debt significantly outweighs the charge. Scenarios where early repayment might be considered:

1. Significant Windfall: If you receive a large inheritance or lump sum, the guaranteed saving achieved by avoiding future interest payments might exceed the one-time ERC, even considering lost investment returns.

2. Downsizing: If you are selling your large family home to move into a smaller, cheaper property, using the surplus funds from the sale to clear the RIO debt may be the most straightforward option, even if an ERC is due.

3. Refinancing (Less Common for RIOs): If interest rates have dropped dramatically and you are outside the ERC period (or the ERC is small), switching to a cheaper standard mortgage could save money over time. However, RIO mortgages are often chosen precisely because standard mortgages are no longer available due to age or income constraints.

Protecting Yourself: Getting Financial Advice

Given the complexity of RIO contracts and the high costs associated with early redemption, obtaining professional, independent financial advice is paramount. An FCA-regulated broker or adviser can:

  • Calculate the true cost of early repayment versus keeping the mortgage.
  • Verify if a “portable” RIO product allows you to transfer the debt (and potentially avoid the ERC) if you move house.
  • Help you understand the tax implications of using certain funds (like investments) to clear the debt.

Before making any major decision regarding your retirement finances, you should seek guidance from a qualified specialist. You can find guidance on choosing the right adviser through governmental resources, such as the MoneyHelper service:

People also asked

How long do Early Repayment Charges typically last on RIO mortgages?

ERCs typically last for the duration of the initial fixed-rate period, often spanning 5, 7, or even 10 years. Once this period expires, you can usually repay the mortgage capital without incurring any penalty beyond a small administrative fee.

Can I make overpayments on a RIO mortgage without penalty?

Most RIO mortgages, like standard residential products, allow you to make limited overpayments annually (typically 10% of the outstanding balance) without incurring an ERC. Any overpayment exceeding this contractual limit will likely trigger the charge on the excess amount.

What is the difference between a RIO mortgage and Lifetime Mortgage Equity Release?

The crucial difference is interest payment: a RIO mortgage requires monthly interest payments, meaning the debt size stays stable. A Lifetime Mortgage (a common type of equity release) allows the interest to ‘roll up’ and compound onto the capital, meaning the debt grows significantly over time, but requires no monthly payments.

What happens to the capital on a RIO mortgage if the borrower dies?

If the last surviving borrower dies, the RIO mortgage becomes fully repayable. The lender usually allows a grace period (often 12 months) for the executors of the estate to sell the property and use the proceeds to clear the outstanding capital debt.

Are there circumstances where the ERC is waived?

Generally, ERCs are contractual and are only waived in specific, defined circumstances listed in the agreement, such as if the borrower dies. Lenders typically do not waive ERCs simply because the borrower wishes to downsize or has received a large sum of money.

Can I switch my RIO mortgage to a new lender to avoid the ERC?

No. Switching or remortgaging to a new lender (known as refinancing) requires you to clear the debt with the original RIO provider, which will trigger the full Early Repayment Charge just as if you had repaid it using cash savings. You would need to wait until the ERC period has expired before switching penalty-free.

Final Considerations for Early Redemption

While the option to repay a RIO mortgage early offers flexibility, it should be approached with caution due to the significant financial outlay involved. Ensure you calculate the total settlement figure, including all charges, and compare that against the long-term saving on interest.

The RIO market is regulated by the Financial Conduct Authority (FCA), ensuring fair practice. If you are unsure about the terms of your contract or believe the charges levied are incorrect, you have the right to challenge them via the lender’s complaints procedure, and subsequently through the Financial Ombudsman Service (FOS).
