Pension Drawdown vs Annuity: A UK Comparison

For a defined contribution pension saver in the UK, the choice between an annuity and drawdown is the headline decision at retirement. The two structures handle the same pension pot in fundamentally different ways: an annuity insures against longevity by exchanging the pot for guaranteed income, while drawdown keeps the pot invested and gives the saver flexible access. Neither dominates universally. The right answer depends on the saver's other income, health, dependants, attitude to investment risk, and inheritance objectives.

This article sets the two side by side, works through the trade-offs in numbers, and explains the hybrid approaches that combine the best of each.

The structural difference

An annuity is a contract with an FCA-authorised insurance company. The saver exchanges a lump sum (typically the residual 75 percent of a defined contribution pot after the 25 percent tax-free element) for a guaranteed lifetime income. The income is set at purchase and locked in for life. The pot is gone; the income is the only asset.

Drawdown is a continuation of the pot under different rules. The saver moves the pot into a drawdown account with their pension provider, chooses an investment strategy (or accepts a default investment pathway), and takes income and lump sums as required. The pot stays invested, rises and falls with markets, and remains accessible.

Income comparison

The simplest comparison is income per pound of pot. A 65-year-old healthy retiree in early 2026 might receive an annuity quote in the region of 6 to 7 percent gross of tax on a single-life level basis. The same retiree using drawdown commonly targets a sustainable withdrawal rate of around 3.5 to 4 percent for a 30-year horizon, depending on the investment strategy and the risk tolerance.

On these numbers, the annuity pays more income in absolute terms in the early years, especially if the saver is healthy enough to qualify only for standard rates. The drawdown rate looks lower because it is calibrated for a long retirement with rising real income; the annuity rate looks higher because it includes return of capital that the saver cannot reclaim.

Where drawdown can pay more

Where the saver dies relatively early in retirement, drawdown can deliver more cumulative income than the equivalent annuity because the unused pot passes to beneficiaries. Where investment returns are unusually strong, drawdown can sustain higher withdrawal rates and outpace the annuity over time. Where the saver qualifies for enhanced annuity rates because of health, the gap narrows or reverses in the annuity's favour.

Longevity risk

Longevity risk (the risk of outliving the pot) is the single biggest structural difference between the two products. An annuity transfers longevity risk to the insurer: the income continues regardless of how long the saver lives. Drawdown retains longevity risk: the saver carries the risk that withdrawals exhaust the pot during their lifetime.

This matters most for retirees in good health with limited other income. A retiree at 65 has roughly a one-in-four chance of living past 90 on Office for National Statistics life expectancy data. Planning for the median is not the same as planning for the tail.

Investment risk

Drawdown's flexibility comes with investment exposure. The pot is invested and rises and falls with markets. Sequence-of-returns risk (a poor market early in retirement permanently impairing the pot) is the dominant investment risk in drawdown. Annuities have no equivalent risk: the income is contractual and the saver does not need to manage assets to receive it.

Inheritance treatment

Under current UK rules, uncrystallised drawdown pots pass to beneficiaries outside the inheritance tax regime. Beneficiaries inherit the pot and pay income tax on withdrawals according to the saver's age at death (tax-free if before 75, taxable if at or after 75).

Annuity payments stop on the annuitant's death unless joint-life, guarantee, or value protection features were purchased at outset. Joint-life annuities continue to a surviving spouse or partner at a defined percentage; guarantee periods continue payments for the remainder of a fixed term (typically 5 or 10 years) regardless of survival.

The Autumn Budget 2024 announced plans to bring unused pension pots within the IHT regime from April 2027. The gov.uk authoritative page holds the current implementation position and should be checked before relying on the historical treatment.

Tax treatment

Both annuity income and drawdown income above the 25 percent tax-free element are taxed as earned income through PAYE. The aggregated marginal rate depends on the saver's total taxable income in the year.

Taking taxable income from drawdown triggers the Money Purchase Annual Allowance, currently 10,000 pounds a year. Buying an annuity also triggers the MPAA. Savers who plan to continue contributing significantly to a pension should consider the MPAA implications before triggering either route.

Reversibility

Annuities are not reversible: the lump sum is gone once the contract is in force and the income is contractual for life. Drawdown is fully reversible in the sense that the strategy can be revised at any time: the saver can change the withdrawal rate, the investment mix, or buy an annuity with the residual pot at any later point.

This asymmetry favours drawdown for savers with uncertain future needs or who want to keep options open. It favours the annuity for savers who want a definitive, set-and-forget income that does not need ongoing management.

Hybrid approaches

A common UK strategy uses both products. An annuity (often a level single-life shape, or joint-life where appropriate) covers essential non-discretionary spending: rent or mortgage, utilities, food, basic transport. The State Pension typically forms part of this floor. Drawdown handles discretionary spending and inheritance flexibility.

Phased annuitisation

Some retirees buy annuities in tranches over a 5- to 15-year window, starting with a smaller annuity at the planned retirement date and adding to it at older ages when rates are typically higher. This diversifies gilt yield timing risk and takes advantage of the higher rates available at older ages.

Floor and upside

The floor-and-upside approach annuitises enough of the pot to cover essential spending and leaves the rest in drawdown for discretionary spending and inheritance. The split depends on the size of the pot relative to essential spending and the saver's tolerance for investment risk.

When each route dominates

Annuity-favouring profiles

Savers with limited other income, no significant inheritance objectives, low tolerance for investment risk, qualifying health for enhanced rates, or a strong preference for set-and-forget simplicity tend to find annuities more suitable. The same applies to savers who would otherwise spend the residual pot too quickly: an annuity removes the temptation by removing the asset.

Drawdown-favouring profiles

Savers with substantial other income (such as State Pension plus rental income or defined benefit pension), inheritance objectives, willingness to manage investment risk, or expectation of significant lifestyle changes in retirement tend to find drawdown more suitable. The MPAA can be a planning factor for those still contributing.

Risks and downsides to weigh

Annuity risks: permanence, inflation erosion on level shapes, single-day gilt yield exposure at purchase, opportunity cost if life is short. Drawdown risks: investment loss, sequence-of-returns risk, longevity, tax-band creep on large withdrawals, MPAA on contributions.

Both products carry counterparty risk that is mitigated by FCA regulation and the Financial Services Compensation Scheme. Annuity contracts are covered at 100 percent with no upper limit; drawdown pots are protected up to 85,000 pounds per provider for the long-term insurance element and through asset segregation for the investment element.

Mortality cross-subsidy: why annuity income exceeds a sustainable drawdown rate

The most counter-intuitive feature of annuity pricing is mortality cross-subsidy. Annuity rates exceed a saver's safe withdrawal rate on the same pot not because the provider invests better but because the pool of annuitants who die earlier than average effectively subsidise the income of those who live longer. The provider distributes the unused capital of early deaths to fund continuing payments to the survivors. This pooling is the structural reason a 65-year-old can secure a 6 to 7 percent gross rate from a lifetime annuity, while sustainable drawdown rates calibrated for a long retirement sit closer to 3 to 4 percent.

The implication is that the annuity rate is not directly comparable to an investment return. It includes both the return of capital and the mortality cross-subsidy that no individual saver can replicate alone. Drawdown sacrifices the cross-subsidy in exchange for retaining the capital.

Recent rate increases and underwriting variation

UK annuity rates rose sharply through 2022 and 2023 as fifteen-year gilt yields climbed to their highest levels in over a decade. The rate available to a healthy 65-year-old on a single-life level annuity reached the region of 6 to 7 percent gross in early 2026, materially above the rates that prevailed during the 2009 to 2021 low-yield period. The shift has narrowed the income gap between annuities and drawdown and renewed mainstream interest in the annuity option.

Underwriting variation between providers can be substantial, particularly for enhanced annuities. A smoker, a diabetic, or an applicant with significant cardiovascular history can qualify for enhanced rates that exceed standard quotes by 10 to 25 percent. The best quote from the most generous underwriter on a given day is regularly several percentage points of annual income better than the worst quote on the same case. Open Market Option shopping is essential.

Joint-life, guarantee period, and value protection

Annuity contracts can be customised at purchase with features that affect the income paid. A joint-life annuity continues to pay a defined percentage (typically 50, 66, or 100 percent) to a surviving spouse or partner after the annuitant dies; the trade-off is a lower starting income because the provider expects to pay for longer. A guarantee period (typically 5 or 10 years) ensures payments continue for the remainder of the guarantee even if the annuitant dies early; the trade-off is a modest reduction in starting income. Value protection refunds the unused balance of the original premium (less income paid) to a beneficiary on early death; the trade-off is another modest reduction.

Each feature is priced individually and stacks with the others. A joint-life escalating annuity with a 10-year guarantee starts at a much lower income than a single-life level annuity, but it provides much broader survivor and estate protection.

Inflation protection options

Level annuities pay the same gross income every year. Escalating annuities pay a starting income that rises by a fixed percentage (commonly 3 or 5 percent) or in line with Retail Prices Index or Consumer Prices Index inflation. The State Pension under the triple lock provides a meaningful inflation-linked income floor for most UK retirees, which influences how much additional inflation protection the annuity layer needs to provide.

The post-2022 inflation period was a reminder that fixed nominal income can lose real spending power quickly. Retirees who had bought level annuities in the 2015 to 2020 period saw the real value of their income fall noticeably between 2022 and 2024 as headline inflation rose into double digits. Escalating annuities mitigated this but at the cost of a substantially lower starting income.

Hybrid strategies: floor plus upside

The most common UK approach for retirees with substantial defined contribution savings is a hybrid. An annuity covering essential, non-discretionary spending (housing, utilities, food, basic transport) provides a guaranteed floor that does not depend on market performance. The State Pension typically forms part of this floor. Drawdown handles discretionary spending and inheritance flexibility, exposed to investment risk but reflecting the saver's individual circumstances.

The split between annuity and drawdown is a personal planning decision. Common splits range from 30 percent annuitised (for retirees with substantial other income or strong inheritance objectives) to 70 percent annuitised (for retirees with limited other income and low risk tolerance). Regulated advice is sensible for any non-trivial split, particularly where the underlying tax position is complex or the family structure involves cross-border or trust considerations.

Important: This article is for general information and does not constitute regulated financial advice. The choice between annuity and drawdown depends on individual circumstances including health, dependants, other income, tax position, and inheritance objectives. Regulated advice from an FCA-authorised firm is strongly recommended, particularly for larger pots or complex family situations.

Frequently asked questions

Which gives more income, drawdown or annuity?

In the early years, an annuity typically pays more income per pound of pot because the rate includes return of capital. Drawdown calibrated for a 30-year horizon pays a lower sustainable rate. Where investment returns are strong or the saver dies relatively early, drawdown can deliver more cumulative income through the unused pot.

Can I switch from drawdown to an annuity later?

Yes. The residual drawdown pot (or any part of it) can be used to buy an annuity at any time. Rates available at the later purchase date depend on the saver's age and health at that point and on the prevailing gilt yield environment.

Can I switch from an annuity to drawdown later?

No. Lifetime annuities are irrevocable; the lump sum cannot be reclaimed. The secondary annuity market that was proposed in 2015 was abandoned in October 2016. Savers who want to keep the option to switch must not buy a lifetime annuity in the first place.

What happens to my pension when I die under each route?

Under current rules, an uncrystallised drawdown pot passes to beneficiaries outside the IHT regime; the tax position on beneficiary withdrawals depends on the saver's age at death. An annuity stops on the annuitant's death unless joint-life, guarantee, or value protection features were purchased. Planned reforms from April 2027 will change the IHT treatment of pension pots.

Does either choice trigger the MPAA?

Both do, as soon as any taxable income is taken. The Money Purchase Annual Allowance caps future defined contribution pension contributions at 10,000 pounds a year and cannot be reversed. Savers planning to continue significant contributions should consider the MPAA implications before triggering either route.

Can I combine annuity and drawdown?

Yes, and this is a common UK approach. An annuity covers essential non-discretionary spending as a guaranteed floor; drawdown handles discretionary spending and inheritance flexibility. The split between the two is a personal planning decision and benefits from regulated advice.
