What Is Pension Drawdown? The Complete Guide to Flexible Retirement Income
Updated: 7 days ago
Your SIPP does not stop working when you retire. Neither should your investment framework. Pension drawdown is what allows both of those statements to be true at the same time.
Pension drawdown in 30 seconds
Short answer: pension drawdown (flexi-access drawdown) lets you take income from a defined contribution pension, such as a SIPP, while the rest stays invested. You choose how much to take and when. Nothing is guaranteed: if you take too much, or markets fall early in retirement, the money can run out.
Earliest age: 55 now, rising to 57 from 6 April 2028 for most people.
Tax-free cash: usually 25% of what you move into drawdown, capped at £268,275 in total for most people (the Lump Sum Allowance, 2026/27).
Everything else you take is taxed as income at your marginal rate, and your first withdrawal is often taxed on an emergency basis.
Taking taxable income triggers the Money Purchase Annual Allowance: future pension contributions with tax relief drop from £60,000 to £10,000 a year.
From 6 April 2027 most unused pension funds count towards your estate for inheritance tax (Finance Act 2026).
The biggest risk is sequence of returns: a market fall in the first few years does far more damage than the same fall later.
The traditional retirement model was simple: build up a pension pot, buy an annuity and receive a fixed income for life. Since the 2015 pension freedoms, defined contribution pension holders have had full flexibility over how and when they access their pot, and buying an annuity is no longer compulsory at any age. For many self-directed investors, flexible drawdown is now the default.
Drawdown keeps the portfolio invested, so it can keep growing through your retirement years while you take income flexibly. But it brings risks that an annuity does not, sequence of returns risk above all. Understanding those risks, and having a systematic process for managing them, is the difference between drawdown as a strategy and drawdown as a gamble.

The Three Options at Retirement: Drawdown, UFPLS, and Annuity
1. Flexi-Access Drawdown
You crystallise your pension pot (or part of it), take 25% as a tax-free lump sum (or leave it uncrystallised to take 25% tax-free from future withdrawals), and move the remaining 75% into a drawdown arrangement. The pot stays invested and you withdraw income as needed - weekly, monthly, quarterly, or in irregular lump sums. Withdrawals from the crystallised drawdown pot are taxed as income at your marginal rate. The pot continues to grow (or shrink) based on investment performance.
2. Uncrystallised Fund Pension Lump Sum (UFPLS)
Rather than crystallising the whole pot upfront, UFPLS lets you take lump sums straight from the uncrystallised fund. Each payment is 25% tax-free and 75% taxed as income. It can suit investors who want occasional lump sums rather than regular income. Two things to know: every UFPLS triggers the Money Purchase Annual Allowance, and you can't take the tax-free cash separately first, so it comes in slices with each payment.
3. Annuity
You exchange your pension pot (or part of it) for a guaranteed income for life from an insurance company. The income is fixed (or inflation-linked at a cost) and continues regardless of how long you live or how financial markets perform. Annuity rates depend on interest rates, your age, health, and the type of annuity. Annuities are most suitable for investors who cannot tolerate investment risk in retirement, have limited other income, or have health conditions that qualify them for an enhanced annuity rate.
Drawdown vs UFPLS vs annuity at a glance
Flexi-access drawdown | UFPLS | Annuity | |
|---|---|---|---|
Income | Flexible, you choose | Lump sums when you want | Fixed, guaranteed for life |
Tax-free cash | Up to 25% upfront | 25% of each payment | Up to 25% before buying |
Investment risk | Yours | Yours | Insurer's |
Triggers MPAA? | Only when you take taxable income | Yes, always | No (most lifetime annuities) |
Can run out? | Yes | Yes | No |
On death | Remaining pot passes to beneficiaries | Remaining pot passes to beneficiaries | Usually stops, unless you add a guarantee or spouse's pension |
The Critical Risk in Drawdown: Sequence of Returns
The most important concept in retirement drawdown planning is sequence of returns risk. It describes the danger of experiencing poor investment returns in the early years of retirement, when withdrawals are being made even if long-run average returns are perfectly adequate.
Here is a worked example. Two investors each retire with £500,000 and take £25,000 at the start of every year. Over ten years they get exactly the same ten annual returns: -20%, -10%, 5%, 8%, 10%, 12%, 15%, 18%, 12% and 20%, an average of 7% a year. The only difference is the order. Investor A gets them in that order, with the bad years first. Investor B gets them in reverse, with the bad years last.
Investor A (bad years first) | Investor B (bad years last) | |
|---|---|---|
Pot at start | £500,000 | £500,000 |
After year 2 | £319,500 | £610,400 |
After year 5 | £310,159 | £829,514 |
After year 10 | £433,642 | £645,245 |
Total taken | £250,000 | £250,000 |
With no withdrawals, both would end on exactly the same £917,287. Taking income is what makes the order matter: Investor A sells shares at low prices in the early years, so less money is left to recover. After ten years Investor A has £211,603 less, despite identical returns and identical withdrawals.
Same returns. Same withdrawals. Completely different outcomes, decided by the order the returns arrived in. This is why the GIP process watches maximum drawdown through the Calmar ratio, and why the process keeps running in the drawdown phase, not just while you are building the pot.
The GIP Approach to Drawdown: Staying Systematic After Retirement
The GIP framework does not stop at the point of retirement. The same five quantitative screens - CROCI, PEG, Sortino, Sharpe, Calmar - continue to apply to the drawdown portfolio. The quarterly review process continues. The only changes in drawdown are: the withdrawal rate becomes a live number to monitor, position sizing may be adjusted to reduce concentration in very high-volatility stocks, and the cash buffer becomes a formal part of the portfolio structure.
The cash buffer approach, holding 1–2 years of planned withdrawals in cash or near-cash within the SIPP is one of the most effective mitigants of sequence of returns risk.
It means that if markets fall 30% in the first year of retirement, withdrawals are funded from the cash buffer rather than from forced sale of equities at depressed prices. The equity portfolio is left to recover before further withdrawals are made from it.
Pension drawdown best practice: 8 rules I'd follow
Get the free guidance first. If you're 50 or over, Pension Wise (part of MoneyHelper, backed by the government) will talk you through your options for free. For a personal recommendation, use a regulated financial adviser.
Decide when to take the tax-free cash. Taking it all upfront is not compulsory. Leaving it uncrystallised keeps it invested, and you can take 25% tax-free slices later.
Set a withdrawal rate and review it every year. Many people start around 4% of the pot. That figure comes from US historical data, so treat it as a starting point, not a promise. See my 4% rule explainer.
Hold a cash buffer. One to two years of planned withdrawals in cash means you don't have to sell shares after a crash.
Withdraw tax-efficiently. Use your £12,570 personal allowance and try to stay within your tax band. If your first withdrawal is over-taxed under emergency tax, reclaim it from HMRC with form P55, P50Z or P53Z rather than waiting until the end of the tax year.
Watch the MPAA if you still work. Once you take taxable income, you can only pay £10,000 a year into pensions with tax relief.
Keep costs low. Drawdown charges, dealing fees and FX all come out of your income. Compare platforms before you start: see AJ Bell vs Hargreaves Lansdown 2026.
Keep your beneficiary nomination up to date, and plan for unused pensions counting for inheritance tax from April 2027.
Frequently Asked Questions: Pension Drawdown
What is pension drawdown?
Pension drawdown (specifically flexi-access drawdown) is a way of taking income from your defined contribution pension in retirement while keeping the remaining pot invested. Rather than converting the whole pension into a guaranteed annuity, you draw income flexibly as needed. The pot continues to grow or shrink based on investment performance, and you have complete control over the timing and amount of withdrawals.
How much can I take in pension drawdown?
There is no maximum withdrawal limit in flexi-access drawdown. You can take as much or as little as you like in any year. The practical limit is sustainability: take too much too early and the pot runs out. Many people start around 4% a year, based on William Bengen's 1994 research on US historical returns, then review it every year against actual performance and spending. See the 4% rule explained.
Is drawdown better than an annuity?
It depends on your circumstances, how much risk you can take and what other income you have. Drawdown offers flexibility, growth potential and the ability to pass on what's left. An annuity offers guaranteed income for life whatever markets do. People with a large pot and other income, such as the State Pension, ISAs or property, often prefer drawdown's flexibility. People who need certainty may want an annuity for their essential spending. Many combine the two.
What is the Money Purchase Annual Allowance (MPAA)?
Once you take taxable income from a defined contribution pension, your annual allowance for future money purchase contributions falls from £60,000 to £10,000. That matters if you plan to keep working and paying in. Taking only your tax-free cash and moving the rest into drawdown without drawing income does not trigger it. Taking taxable drawdown income or any UFPLS does.
What happens to my drawdown pension when I die?
Whatever is left in your drawdown pot passes to the beneficiaries you nominate. If you die before 75, they can usually take it free of income tax (lump sums are subject to the £1,073,100 Lump Sum and Death Benefit Allowance). If you die at 75 or over, they pay income tax at their own rate on what they take. From 6 April 2027, under the Finance Act 2026, most unused pension funds will also count towards your estate for inheritance tax.

Two More Drawdown Questions I Get Asked
How does a flexi access drawdown pension work?
When you access your pension through flexi-access drawdown, you can usually take 25% tax-free, up to £268,275 in total for most people. The rest stays invested in your pension, and you take income from it whenever you choose. Every withdrawal after the tax-free cash is taxed as income, so spreading withdrawals across tax years can keep you out of a higher band. Once you take taxable income, the Money Purchase Annual Allowance cuts what you can pay back in with tax relief to £10,000 a year. You can start from 55, rising to 57 from 6 April 2028 for most people.
Is a drawdown pension a good idea?
It can be, for many people with a decent pot, because your pension stays invested and can keep growing. The trade-off is risk. There is no guaranteed income, and if markets fall early in retirement or you take too much, you could run out of money. If you want an income that can never stop, an annuity does that job. Many retirees mix the two: an annuity to cover the essentials and drawdown for the rest.
