Retirement Interest-Only mortgages — UK 2026/27
Retirement Interest-Only (RIO) mortgages let older homeowners borrow against their property, pay interest only (not capital), and have the loan repaid from the eventual sale of the home — on death or move to long-term care. Created by the FCA in 2018 as a regulated alternative to equity release. Cheaper than equity release. Useful for older homeowners who can afford monthly interest payments but want to release capital or keep their property without an end-date.
What a Retirement Interest-Only mortgage is
A RIO mortgage is a standard interest-only mortgage with three specific features:
- No fixed end date for capital repayment — the capital is repaid only when the property is sold (typically on death or move to long-term care)
- Monthly interest payments throughout — you must demonstrate affordability of these payments from retirement income
- FCA-regulated under standard mortgage rules — not the equity release regime, with all the consumer protections that implies
The FCA introduced RIOs in March 2018 specifically to fill a gap: older homeowners who could afford monthly interest payments but couldn't qualify for standard residential mortgages (which require capital repayment plans).
RIO vs other older-borrower options
| Product | Monthly payments | Interest rate | Capital repayment |
|---|---|---|---|
| Standard residential mortgage | Capital + interest | ~4-5% | Within term |
| Standard interest-only mortgage | Interest only | ~4-5% | End of term — requires repayment plan |
| RIO mortgage | Interest only | ~5-6% | Death or LTC, from property sale |
| Lifetime mortgage (equity release) | None (rolls up) or optional | ~6-8% | Death or LTC, from property sale |
| Home reversion plan | None | N/A (you sell share of property) | You no longer own that share |
When RIO is the right choice
Existing interest-only mortgage approaching maturity
Many UK homeowners took 25-year interest-only mortgages in the 1990s-2000s expecting endowment policies or other plans to repay the capital. Those plans often underperformed. Result: at age 65-75, the original mortgage matures with capital still owing.
RIO offers a clean refinancing solution: switch the existing IO mortgage to a RIO, continue paying interest, repay capital eventually from property sale.
Release equity from the home (cheaper than equity release)
An asset-rich, income-modest retiree (typical "house rich, cash poor" UK situation) might want to release £50-£100k to:
- Top up retirement income
- Help children with deposits
- Pay for home improvements / adaptations
- Pay off other debts
A RIO mortgage at ~5.5% costs around £225/month interest on £50k. Equivalent lifetime mortgage (equity release) at ~6.5% costs no monthly payment, but the debt compounds: £50k at 6.5% compound for 20 years = ~£176k owed at the end.
If you can afford monthly interest, RIO is structurally cheaper than equity release by a large margin.
Bridging to pension access
Borrowers in their late 50s or early 60s who'd struggle to qualify for a 25-year standard mortgage (term wouldn't end before retirement) can use RIO to extend their borrowing into retirement, with a plan to pay off from pension lump sum or downsizing later.
When RIO is NOT the right choice
If you can't afford monthly interest payments
The defining feature of RIO is that you affordably pay monthly interest from retirement income. If your pension and other retirement income won't comfortably cover this for the rest of your life, you can't qualify for RIO. Lifetime equity release (rolled-up interest, no payments) is the alternative.
If you want to clear the debt entirely
RIO doesn't clear the capital; it just defers it forever (to your eventual death/move). If you want to live mortgage-free in retirement, RIO doesn't deliver that. Downsizing or selling is the alternative.
If preserving the estate for inheritance is the top priority
RIO's compounding interest payments are real money out of your estate each year. Over a 25-year retirement, you might pay £100,000+ in interest on a £50,000 loan. That's all from family inheritance. Equity release's rolled-up interest has the same compounding problem but with no monthly outflow.
Affordability requirements
RIO lenders run affordability tests on the monthly interest payment:
- Borrower's retirement income (state pension + private pensions + other guaranteed income) must comfortably cover interest payments
- For couples, joint income basis — but lenders increasingly look at sole-survivor scenario (if one spouse dies, can the survivor still afford payments?)
- Income stress tested against rate rises (typically +1-3%)
The sole-survivor test catches many couples. If the household relies heavily on one spouse's pension, the survivor might fail affordability when alone. Lenders may require:
- Smaller loan amounts
- Joint life annuities to guarantee income to survivor
- Life insurance on the higher-earning spouse

Key features to compare
No-negative-equity guarantee
Some RIOs include this: if the property sale doesn't cover the loan when due, the lender accepts the shortfall (no claim on other estate assets). Originally pioneered by equity release; now offered on some RIOs. Worth having if available.
Early Repayment Charges (ERCs)
Some RIOs have ERC for early repayment within the first 5-10 years. If you might downsize or repay during that period, look for low or no ERC products.
Portability
If you might move home, look for a "portable" RIO that transfers to a new property. Not all RIOs offer this.
Overpayment allowance
Most RIOs allow 10% annual overpayment without penalty. Useful if you want to reduce capital over time even though it's not required.
RIO vs equity release — detailed comparison
Cost over 20 years on £75,000 borrowed
Scenario: 70-year-old homeowner borrows £75,000 against a £500,000 home.
RIO mortgage at 5.5%
- Monthly interest payment: ~£344/month
- Over 20 years (assuming you live to 90): £82,500 in interest paid from income
- Outstanding capital at death: £75,000 (unchanged)
- Total cost to estate: £82,500 interest paid + £75,000 capital = £157,500
Lifetime equity release at 6.5% (rolled up)
- Monthly payment: £0
- Loan grows from £75,000 to £264,000 over 20 years (compound interest)
- Outstanding at death: £264,000
- Total cost to estate: £264,000
RIO saves £100k+ over equity release in this scenario
The economic case is stark IF you can afford the monthly payments. The trade-off is purely about cashflow: RIO requires ~£344/month from your retirement income; equity release requires £0.
Decision framework: is RIO right for you?
RIO suits you if you...
- Are 55+ (most lenders) or 60+ (some lenders)
- Have retirement income comfortably covering monthly interest payments
- Want to release capital from your property without selling/downsizing
- Don't want the compounding cost of equity release
- Are comfortable with the loan eventually being repaid from property sale
- Have an existing interest-only mortgage you need to refinance
RIO doesn't suit you if you...
- Can't comfortably afford monthly payments now or in any plausible future scenario
- Have a clear plan to clear the mortgage entirely (downsizing planned soon)
- Want to preserve maximum estate value (consider whether borrowing at all is right)
- Need very large equity release (RIO loan-to-value is typically lower than equity release)
Getting advice
RIO mortgages are FCA-regulated and require advised sales (you can't buy direct without advice). Use:
- Specialist later-life mortgage advisers (Equity Release Council members for breadth across RIO + equity release)
- Independent financial advisers with later-life specialism
- Some mainstream mortgage brokers (Habito, London & Country) handle RIO alongside standard mortgages
Adviser fees: typically £500-£2,000 (often paid via lender commission rather than directly).
Impact on your estate
A RIO mortgage at death:
- The outstanding capital is owed to the lender
- The property is typically sold within 12 months of the second-to-die's death (or move to LTC for couples; immediate death for single applicants)
- Sale proceeds pay off the mortgage; remaining equity goes to the estate
- If a no-negative-equity guarantee applies, the estate isn't liable for any shortfall
Important: the mortgage reduces the value of the estate for IHT purposes. A £500k home with a £75k RIO = £425k net value in the estate. Combined with the RNRB and NRB, this often eliminates IHT exposure (vs the £500k home owned outright).
Frequently asked questions
What's the minimum age for RIO?
Most RIO lenders require borrowers to be 55+; some require 60+. The youngest applicant determines eligibility for couples.
Can I pay off the capital before death?
Yes — most RIOs allow voluntary capital repayments (within an annual overpayment allowance). Some have ERC if repaying large amounts in early years.
What if my income falls significantly in retirement?
If you can no longer afford interest payments, you typically need to: (1) increase income, (2) repay the mortgage from other assets, (3) sell the property, or (4) negotiate a conversion to a lifetime mortgage (equity release). Lenders won't typically force a quick sale if you have a temporary affordability issue.
Can two homeowners be on a RIO together?
Yes — joint RIOs are common. The mortgage continues for both applicants' lifetimes; the property is sold when the second dies or moves to long-term care. Affordability is assessed on joint income but increasingly with attention to sole-survivor scenarios.
Is there inheritance tax planning value?
A RIO reduces the estate value by the outstanding loan, which can reduce IHT exposure. For estates near or above IHT thresholds, RIO can serve as an IHT planning tool alongside its primary purpose. Not usually the main reason to choose RIO but worth considering.
How much can I borrow on RIO?
Typically 25-55% of property value, depending on age, income and lender. Older borrowers can borrow higher percentages (lender expects shorter remaining lifetime, so less interest compounding risk). Single applicants typically borrow less than couples for the same property.
