What Is an Annuity? The Longevity Insurance Perspective
In the broader financial planning context, life insurance protects against the risk of dying too soon — leaving dependants without sufficient support. An annuity addresses the opposite risk: living too long, and outliving your savings.
The mechanics are straightforward. You surrender a lump sum — typically from a pension fund accumulated over a working lifetime — to an insurance company. In return, the insurer commits to paying you a specified income for the rest of your life. Whether you live to 70 or to 100, the income continues. The insurer bears the longevity risk; you bear no investment or sequence-of-returns risk.
This is why an annuity sits within the protection spectrum alongside life assurance. Both involve an insurance company pricing and assuming a mortality-related risk. Life insurance prices the risk that you die early; an annuity prices the risk that you live for longer than average.
Why Annuities Are Relevant Again in 2026
For much of the 2010s and early 2020s, annuities fell dramatically out of favour. Ultra-low interest rates — the Bank of England base rate below 1% from 2009 to 2022 — compressed annuity rates to historically poor levels. The advent of pension freedoms in 2015 meant retirees were no longer required to purchase an annuity. Many chose drawdown instead.
The interest rate environment changed sharply from 2022. UK gilt yields rose substantially, and by 2023–2024 had reached levels not seen since before the 2008 financial crisis. Because annuity rates are closely linked to long-term bond yields — insurers invest the premium income in bonds to back the guaranteed payments — the rates improved dramatically.
As of 2026, a 65-year-old man with a £100,000 pension pot and no underlying health conditions could typically purchase a standard level annuity paying approximately £6,500–£7,500 per year. For a 65-year-old woman, rates are typically slightly lower (insurers account for longer life expectancy). These figures are illustrative — actual rates vary by provider, terms, and individual circumstances.
Enhanced and impaired life annuities can pay considerably more. A 65-year-old with Type 2 diabetes, or a former smoker, or someone with a BMI above certain thresholds, may be assessed as having a shorter-than-average life expectancy and offered a higher income accordingly. The improvement can be substantial — 20–40% higher than a standard rate in some cases.
Types of Annuity
Level Annuity
The simplest form: a fixed income for life. The payment is fixed at outset and never changes. The risk is inflation erosion — if the annuity pays £7,000 per year and inflation averages 3% per year, the real purchasing power of that income halves over approximately 24 years.
Level annuities offer the highest initial income of all annuity types, which can be attractive — particularly in the early years of retirement when activity and expenditure are typically highest.
Escalating Annuity
The income rises each year by a fixed percentage — commonly 3% or 5% — or in line with the Retail Prices Index (RPI) or Consumer Prices Index (CPI). The starting income is lower than a level annuity, but the real value is better protected over a long retirement.
Whether an escalating annuity produces more lifetime income than a level annuity depends on how long you live. If you live beyond the "crossover point" — typically 10–15 years into retirement depending on the escalation rate — the escalating annuity wins. If you die earlier, you would have been better off with the level annuity's higher initial payments.
Enhanced and Impaired Life Annuity
If you have a medical condition or lifestyle factor that reduces life expectancy, you qualify for an enhanced annuity — a higher income reflecting the statistical expectation that you will draw payments for fewer years. Qualifying conditions include:
- Type 2 diabetes
- Heart disease or history of heart attack
- High blood pressure requiring medication
- Stroke history
- Certain cancers in remission
- COPD or other chronic respiratory conditions
- Obesity (BMI above certain thresholds)
It is critically important to shop the annuity market across multiple providers and disclose your full health history. An enhanced annuity is not available by default — it requires application and medical assessment. The uplift in income can be significant.
Joint Life Annuity
Covers two lives — typically a married couple — and pays the income for as long as either partner is alive. On the first death, the annuity continues to pay to the survivor, either at the same rate or at a reduced rate (typically 50% or 67%). This structure is appropriate for couples where both partners depend on the income stream.
Joint annuities have a lower initial rate than single-life annuities, because the insurer is committing to a longer expected payment period. For couples, this trade-off is generally worthwhile.
Fixed-Term Annuity (Temporary Annuity)
A guaranteed income for a specified period — 5, 10, or 15 years — rather than for life. At the end of the term, a "maturity value" is returned, which can then be used to buy another annuity or enter drawdown.
Fixed-term annuities are appropriate for people who need income certainty for a specific period while remaining uncertain about whether a lifetime annuity is the right long-term decision. They are not an alternative to a lifetime annuity in the same structural sense.
The Currency Problem for International Retirees
For UK-resident pensioners, the currency issue does not arise. For someone living in retirement in Spain, Thailand, the UAE, Bali, or Egypt, it is significant.
A UK annuity pays in GBP. If your living expenses — accommodation, food, local transport, healthcare — are in EUR, THB, AED, IDR, or EGP, you are converting GBP income into local currency every month for the rest of your life. Over a retirement of 20–30 years, currency movements can materially affect your standard of living.
Historical GBP/EUR exchange rates illustrate the point: sterling has traded between approximately 0.80 and 1.20 to the euro over the past 20 years — a range of 50%. Someone who retired in 2006 and purchased a level annuity in GBP experienced a very different EUR income trajectory than they would have planned for.
Currency risk cannot be hedged affordably for a lifetime income stream. Short-term currency hedging products (typically 1–3 years) exist, but their costs and complexity make them impractical as a permanent solution for pension income.
Practical approaches for international retirees include:
Drawdown instead of annuity: Pension drawdown allows you to vary the amount withdrawn each year and to hold the fund in a range of currencies or currency-hedged investment funds. This trades annuity certainty for currency flexibility and investment risk.
Partial annuity, partial drawdown: Use a portion of the pension to buy an annuity matching GBP obligations (for example, if you retain UK-based expenses — a UK mortgage, payments to UK-based dependants), and keep the remainder in drawdown for local-currency spending.
Local or offshore annuity: Some offshore pension and annuity providers offer products in currencies other than GBP. These are less standardised and require specialist advice.
The "Annuity as Floor" Strategy
A widely used retirement income strategy is to establish a "floor" of guaranteed income sufficient to cover essential expenditure, and then to hold a "discretionary" pot in drawdown for variable spending.
Under this approach:
- Essential expenditure — accommodation costs, utilities, food, basic healthcare premiums — is funded by guaranteed income sources: State Pension, any defined benefit pension, and a purchased annuity if needed
- Discretionary expenditure — travel, dining, leisure — is funded from drawdown, which varies with investment performance
This strategy provides income security for the basics (preventing "ruin risk" — the scenario of genuinely running out of money) while maintaining flexibility and potential upside on the discretionary element.
For international retirees, the floor strategy works best when the guaranteed income corresponds to GBP-denominated obligations, with local-currency spending funded through drawdown.
When Drawdown Beats an Annuity
The annuity versus drawdown decision is one of the most consequential financial choices a retiree makes. Drawdown is generally more appropriate when:
- Estate planning is a priority: An annuity extinguishes on death (or on second death for a joint annuity). Unspent pension funds in drawdown pass to beneficiaries and can be a tax-efficient way of leaving wealth — though note that from 6 April 2027 most unused pension funds and death benefits will fall within the deceased's estate for inheritance tax purposes (Finance Act 2026), which significantly reduces the IHT advantage that drawdown previously held over an annuity.
- Other guaranteed income is already adequate: If State Pension and defined benefit pension income already covers essential living costs, an annuity may provide little marginal security benefit.
- You have shorter-than-average life expectancy: An annuity is a bet on living a long time; if your health suggests otherwise, drawdown retains more capital for your estate.
- Flexibility is important: Drawdown allows you to vary withdrawal amounts as needs change — taking more in active early retirement, less later, or making large one-off withdrawals for specific purposes.
The annuity is generally more appropriate when:
- Longevity risk is a dominant concern
- You have no other reliable income sources
- Investment volatility would be psychologically or financially distressing
- You value simplicity and certainty above all else
