This is not a bet on interest rates. It is a decision about who carries the risk that you live longer than expected, or that markets fall early — you, or an insurer.
Pension freedoms made drawdown the default choice and annuities unfashionable, and a decade of commentary has treated that as settled. It is not. The two options answer different questions, and the right answer depends far more on your circumstances than on any general argument about which is better value.
Stripped down: an annuity converts capital into a guaranteed income for life, transferring longevity and investment risk to an insurer. Drawdown keeps the capital invested and pays you from it, keeping both risks with you along with the upside and whatever is left at the end.
The Comparison That Matters
| Drawdown | Annuity | |
|---|---|---|
| Income certainty | None — depends on returns and withdrawals | Guaranteed for life |
| Longevity risk | Yours | The insurer's |
| Investment risk | Yours | The insurer's |
| Flexibility | High — vary income year to year | None once purchased |
| What is left on death | The remaining pot | Depends on the options bought |
| Inflation | Depends on returns | Only if you buy escalation, which costs income |
| Reversible | Yes — you can annuitise later | No |
The asymmetry is the point. Drawdown can be converted into an annuity at any later date. An annuity cannot be converted back. That makes drawdown the option that keeps the decision open — which is an argument for starting there, not an argument for never annuitising.
Sequence Risk: The Danger Specific to Drawdown
Two retirees can experience identical average returns over twenty years and end up in completely different places, because of when the bad years fell. Withdrawing a fixed income from a portfolio that falls sharply in the first few years means selling more units at low prices, and the pot may never recover even if markets do. This is sequence risk, and it is the main reason drawdown fails when it fails.
The standard mitigations are holding a cash buffer of one to three years of spending so withdrawals do not have to come from a falling market, and being willing to reduce income after a bad year — which requires having spending flexibility in the first place.
What Annuity Rates Depend On
- Age. The single largest factor. Rates improve materially the later you buy, because the expected payment period is shorter.
- Health and lifestyle. Enhanced annuities pay more to people with medical conditions or a smoking history. A large number of people never disclose and buy a standard rate they did not need to accept.
- Options chosen. A spouse's pension, a guarantee period and inflation escalation all reduce the starting income.
- Interest rates at the time of purchase, which is the factor everyone focuses on and cannot control.
The Middle Routes
- Annuitise the floor, draw down the rest. Buy enough guaranteed income to cover essential spending, and run the balance in drawdown for everything else. This is the arrangement many advisers reach for, and it removes the failure mode that actually matters.
- Defer the annuity. Use drawdown in early retirement and annuitise in your seventies, when rates are more favourable and health may support an enhancement.
- Phase the crystallisation. Take benefits in slices rather than all at once, which spreads taxable income and preserves the 25% tax-free element across years.
Tax and Practical Points
Both routes are taxed the same way on the taxable element: as income, at your marginal rate, with a first payment likely to be overtaxed under the emergency code — see emergency tax on pension withdrawals. Drawing taxable income flexibly triggers the £10,000 money purchase annual allowance, which matters if you are still working and contributing. And the tax-free element is capped by the £268,275 lump sum allowance.
For anyone considering retiring abroad, both routes interact with treaty rules on pension income — and an annuity purchased in sterling creates a lifetime currency exposure, as our note on currency risk explains.
Nothing Here Is a Recommendation
This is a description of a trade-off, not advice on which side of it to take. Retirement income decisions are regulated advice for good reason, and the annuity half is irreversible. If the pot is a significant part of your retirement, this is a decision to take advice on.
Frequently Asked Questions
Is drawdown always better than an annuity?
No. Drawdown keeps flexibility and any remaining capital, but leaves you carrying longevity and investment risk. An annuity transfers both to an insurer, which is worth a great deal to someone with no other guaranteed income.
Can I change my mind later?
In one direction. Drawdown can be converted into an annuity at any point, but an annuity cannot be undone. That asymmetry is a genuine argument for starting in drawdown.
What is sequence risk?
The risk that poor returns early in retirement, combined with withdrawals, permanently damage a portfolio even if average returns are fine. It is the main reason drawdown fails, and a cash buffer is the usual mitigation.
Should I tell the annuity provider about my health?
Yes. Enhanced annuities pay materially more to people with medical conditions or a smoking history, and many people accept standard rates without ever disclosing.
Can I do both?
Yes, and many advisers recommend it: annuitise enough to cover essential spending and keep the balance in drawdown. It removes the failure mode that matters while retaining flexibility.
