Retirement income planning has become more complex than any previous generation faced. Longer life expectancies, the shift from defined benefit to defined contribution pensions, the reality of multi-currency international retirement, and the risk of outliving your assets all demand a more sophisticated approach than previous generations needed.
This guide covers the sources of retirement income, how to sequence withdrawals, sustainable withdrawal rates, the currency dimension, and practical strategies for building an income that lasts.
The Sources of Retirement Income
Most internationally mobile retirees draw on some combination of these sources:
1. UK State Pension
The full new State Pension pays approximately £12,548 per annum (£241.30 per week at 2026/27 rates) to those with 35 qualifying National Insurance years. It is inflation-linked via the triple lock (the higher of CPI, average earnings, or 2.5%).
For expats, the State Pension is payable wherever you live, but is frozen (not uprated annually) in countries without a bilateral social security agreement with the UK. Countries where the State Pension is frozen include Australia, Canada, India, and South Africa. Countries where it continues to be uprated include EEA countries, the USA, and some others.
If you have gaps in your National Insurance record, voluntary Class 3 contributions (currently £824.20 per year for 2026/27) can fill them. Each qualifying year adds approximately £358 per annum to your State Pension for life — a very high return on a relatively small outlay.

2. UK Defined Contribution Pension / SIPP
Drawdown from a defined contribution pension or SIPP is the most flexible form of retirement income. You keep the pension invested and draw down as needed. Advantages:
- Flexibility — draw more in some years, less in others
- Investment growth continues on the undrawn balance
- Death benefits — uncrystallised funds pass to beneficiaries free of income tax (but subject to IHT from 6 April 2027 under Finance Act 2026, which has been enacted)
- 25% tax-free lump sum (limited to £268,275 Lump Sum Allowance)
Disadvantages:
- Investment risk — your pot can fall as well as rise
- Longevity risk — if you live longer than expected, the pot may run out
- Complexity — requires ongoing management
3. QROPS
If you have transferred to a QROPS, the income drawdown rules will be those of the QROPS jurisdiction rather than UK rules. QROPS can offer advantages in terms of tax treaty treatment of distributions in your country of residence, currency denomination, and estate planning. See our dedicated QROPS and pension transfer guides for details.
4. Offshore Bond Withdrawals
If you have accumulated savings within an offshore investment bond (Isle of Man or Dublin), the 5% annual withdrawal allowance allows you to withdraw up to 5% of original premiums per year on a tax-deferred basis. This can be a very tax-efficient source of income, particularly for UK returnees who use the allowance while in a lower income tax year.
5. Property Income
Rental income from residential or commercial property — UK or overseas — is a common component of expat retirement income. Unlike drawdown, rental income is relatively predictable but not fully certain (voids, maintenance costs, regulatory changes). It is not inflation-linked in a guaranteed sense but historically rents have roughly tracked inflation over long periods.
UK rental income is taxable in the UK even for non-residents (via the Non-Resident Landlord Scheme). Overseas rental income is taxable in the country where the property is located, with potential double taxation treaty relief.
6. Investment Portfolio Income
Dividends, interest, and systematic withdrawals from an unstructured investment portfolio (GIA, stocks and shares ISA) contribute to retirement income. The income is not regular in the way a salary or annuity is, but a well-designed portfolio can generate income alongside capital growth.
7. Annuity (As Backstop)
Annuity rates have recovered significantly from their post-2020 lows, driven by the increase in gilt yields. A level annuity now pays approximately 6–7% per annum of the purchase price for a 65-year-old, versus 4–5% in 2020.
An annuity converts a pot into a guaranteed income for life — eliminating longevity risk entirely. The trade-off is irreversibility (you cannot access the capital once committed) and inflation risk if a level annuity is chosen.
Most planners view annuity purchase as appropriate for a portion of the income need — the portion that represents non-negotiable minimum spending — rather than the whole retirement pot. "Annuitising" essential spending needs (food, housing, healthcare) provides a floor, above which investment assets can be drawn more flexibly for discretionary spending.
The Sequencing Question: What to Draw First?
In a multi-source retirement income structure, the order in which you draw from different sources matters — both for tax efficiency and for long-term sustainability.
A general hierarchy for UK-based or UK-returning retirees:
Phase 1 (Early retirement, 55–70): Draw from GIA and offshore bond first. If UK resident, capital gains tax rates are lower than income tax rates on pension income. The 5% offshore bond annual withdrawal allowance can be used from early in retirement. State Pension has not yet commenced (or is supplemented). Preserve SIPP for later — it continues to grow tax-deferred.
Phase 2 (State Pension commences): When State Pension starts (currently payable from age 66), this fills a portion of income need without using other assets. Assess whether to continue drawing down SIPP or whether the State Pension + other income is sufficient.
Phase 3 (Later retirement, 75+): Drawing down SIPP, annuity purchase for security, managing healthcare costs, considering late-life care needs. The Minimum Required Distribution (RMD) equivalent under UK rules is more flexible than US rules — there is no mandatory drawdown age in the UK.
For non-UK residents: The optimum sequence depends on the tax treaty between the UK and your country of residence, particularly regarding pension income. In many jurisdictions, pension income is taxable locally — drawing down SIPP while resident in a low-tax jurisdiction (UAE, Qatar, Bahrain) can be extremely tax-efficient. Taking large lump sums while in a zero-tax environment and paying UK tax at the basic rate is often better than waiting until you return to the UK and paying higher-rate income tax.
Sustainable Withdrawal Rates: The 4% Rule and Its Critics
The "4% rule" was derived from US academic research by William Bengen in 1994 and popularised by the "Trinity Study". The research found that a portfolio of 50% equities and 50% bonds could sustain annual withdrawals of 4% of the initial portfolio value (adjusted for inflation each year) over a 30-year period without exhaustion, with high historical reliability.
The 4% rule provides a useful starting framework — but requires important caveats for 2026:
It was based on US historical returns. US equities have delivered exceptional long-run returns. Portfolios heavily weighted to international equities may have lower sustainable withdrawal rates.
It assumed a 30-year retirement. Someone retiring at 55 may need a 40-year withdrawal plan. For longer retirements, the sustainable rate is lower — closer to 3.0–3.5%.
It does not account for currency risk. For international retirees spending in a different currency from their investments, currency volatility can significantly affect real withdrawal rates.
The starting valuation matters. The 4% rule was derived from a diversified historical dataset. Retiring at a period of high equity valuations and low bond yields (as was the case in 2020–2021) implies lower prospective returns and therefore a lower sustainable withdrawal rate.
A sensible 2026 framework: Use a starting withdrawal rate of 3.0–3.5% for a long (30–40 year) internationally-based retirement, with the flexibility to adjust downward if markets fall significantly in early retirement years.
Sequence of Returns Risk: The First Decade Matters Most
The most underestimated risk in drawdown retirement is not average returns — it is the sequence of returns in the early years.
A portfolio that earns −25% in year 1, then +25% per annum for the next 9 years will be substantially worse than one that earns +25% per annum for 9 years, then −25% in year 10. Both have the same average return but the early loss is compounded by withdrawals — you are selling units when they are cheapest, reducing the base that recovers.
To manage sequence of returns risk:
- Hold 2–3 years of planned withdrawals in cash or short-duration bonds — insulates against having to sell equities at the bottom
- Reduce equity allocation as you approach retirement — smooths the distribution of returns
- Be willing to reduce withdrawals temporarily during severe market downturns — preserving capital during a bear market significantly improves long-term sustainability
- Consider liability matching for essential income — an annuity or QROPS drawdown plan with guaranteed elements for non-discretionary spending
The Bucket Strategy
The bucket strategy is a practical framework for managing drawdown that addresses sequence of returns risk intuitively:
Bucket 1 — Cash (1–3 years of expenses): Bank deposits, money market funds. This is the spending bucket. Never needs to be sold in a hurry, regardless of markets.
Bucket 2 — Conservative growth (3–7 years of expenses): Short-duration bonds, multi-asset funds, infrastructure. Refills Bucket 1 as it is depleted. Provides stability.
Bucket 3 — Growth (remaining assets): Equities, property, alternatives. Designed to grow over the long term. Provides the engine for long-term real returns and inflation protection.
Each year, Bucket 1 is topped up from Bucket 2 (which is topped up from Bucket 3 growth). This disciplines against panic selling from the growth bucket and provides psychological reassurance — you know that even if markets fall 30%, your next three years of spending are fully funded.
Currency Risk in International Retirement
Retirees spending in one currency while drawing assets denominated in another face currency risk. This is particularly acute for:
- British expats who retired to Spain, France, or Portugal drawing on GBP-denominated assets and spending in EUR
- British expats in Thailand or Bali drawing on GBP and spending in THB or IDR
Strategies to manage currency risk in retirement:
Match assets to liabilities: If you know you will spend in EUR, hold a significant portion of your retirement assets in EUR-denominated investments or in a EUR bank account. Avoid the need to convert large sums at potentially unfavourable rates.
Avoid timing currency conversions in market stress: The worst combination is needing to sell equities during a bear market AND convert the proceeds from a weak GBP. Build a local currency spending reserve that insulates against simultaneous market and currency stress.
Consider property as a natural currency hedge: Property in your country of retirement is denominated in the local currency, generates local currency income, and hedges your housing costs automatically.
Inflation: The Silent Retirement Destroyer
UK inflation averaged approximately 2–3% per annum historically. At 2.5% annual inflation, the purchasing power of £1 falls to approximately 61p over 20 years. A retirement income that feels comfortable at 65 becomes significantly tighter by 85 if not inflation-protected.
Sources of inflation protection in a retirement portfolio:
- State Pension — triple lock provides inflation protection
- Index-linked annuity — guaranteed inflation-linked income (at a cost — much more expensive than level annuity)
- Equities — companies can generally raise prices over time; equity dividends tend to grow with earnings over the long run
- Property income — rents broadly track inflation over long periods
- Index-linked gilts or TIPS — explicit inflation linkage; useful for matching specific future costs
- Real assets (infrastructure, commodities) — tend to have returns linked to inflation
A retirement portfolio that is entirely in cash or level annuities has full inflation exposure. Maintaining equity exposure into retirement (at a reduced level) is the most practical way to preserve long-run purchasing power.
Healthcare Costs: The Planning Variable Most People Miss
Healthcare costs are the most open-ended retirement expenditure. In the UK, the NHS provides free at point of use care, which most UK retirees take for granted. International retirees do not have this.
Private medical insurance for a 65-year-old in most expat markets costs £3,000–£8,000 per annum for comprehensive cover. This escalates with age. By 75–80, international private medical insurance may cost £12,000–£20,000+ per annum, if it remains available at all.
Consider:
- Funding healthcare costs explicitly in your retirement income plan — do not treat it as an afterthought
- Understanding your NHS rights on return — returning to the UK permanently restores NHS access; retaining a UK pension and periodically visiting the UK does not
- Country of retirement healthcare system — Thailand, for example, has excellent and relatively affordable private healthcare; some Eastern European countries have strong public systems. Spain and Portugal have public healthcare available to legal residents
