When people talk about "going into drawdown", what they usually mean is flexi-access drawdown (FAD) — the standard way of taking a flexible income from a defined contribution pension since April 2015. Before that date, anyone who wanted to keep their pot invested and draw an income from it was restricted by "capped drawdown", a system of government limits based on tables of annuity rates that told you the maximum you were allowed to withdraw each year. Flexi-access drawdown swept those caps away. Today, once you move your pension into a flexi-access arrangement, there is no upper limit on how much income you can take in any given year — you could draw nothing at all, draw a modest income, or empty the entire pot in one go, entirely at your own discretion. That freedom is precisely why flexi-access drawdown has become the most popular way of accessing a pension pot at retirement, but it also means the responsibility for making the money last shifts almost entirely onto your own shoulders. This page walks through exactly how flexi-access drawdown works, how it compares with buying an annuity, and the risks worth understanding before you commit.

What is flexi-access drawdown?

Flexi-access drawdown, often shortened to FAD, is a way of taking money from a defined contribution pension pot while keeping the rest of it invested. Rather than converting your entire pot into a fixed income straight away, as you would with an annuity, you move some or all of your pension into a drawdown arrangement and then decide for yourself, year by year or even month by month, how much income to take out of it. The pot itself stays invested throughout, typically in a mix of funds you or your adviser choose, which means its value can continue to rise or fall with the markets even after you've started drawing an income from it.

Flexi-access drawdown replaced an older system called capped drawdown from 6 April 2015, as part of the pension freedoms reforms. Under capped drawdown, the maximum income you were allowed to withdraw each year was set by government tables linked to notional annuity rates and reviewed periodically — in effect, a ceiling designed to stop people running down their pot too quickly and then falling back on the state. Flexi-access drawdown removed that ceiling entirely. If you were already in a capped drawdown arrangement before April 2015, you can generally still convert it to flexi-access drawdown, but you can no longer set up a new capped arrangement — flexi-access is now the only form of drawdown available to new savers. The trade-off for that extra freedom is that flexi-access drawdown also removed the safety net the caps provided, so understanding how much you can sensibly withdraw has become a much more personal, and more important, decision.

How flexi-access drawdown works in practice

To move into flexi-access drawdown, you first need to "crystallise" some or all of your pension pot — the technical term for converting a pot that's still simply growing into one that's now designated for taking benefits. At the point of crystallisation, you're normally entitled to take up to 25% of the amount you're crystallising as a tax-free lump sum, subject to your own lump sum allowances. The remaining 75% moves into a flexi-access drawdown fund, where it stays invested and from which you can then draw a taxable income whenever you choose. You don't have to crystallise your whole pot in one go — many people crystallise smaller portions over several years, a strategy sometimes called phased drawdown, taking a tax-free lump sum and a bit of taxable income from each slice as needed, while the rest of the pot remains uncrystallised and continues growing without yet being exposed to income withdrawals.

Once part of your pot is in a flexi-access drawdown fund, you can take withdrawals as one-off lump sums, as a regular monthly or annual income, or leave it completely untouched for a while if you don't need the money yet — there's no requirement to take any income at all just because you've crystallised the pot. Each withdrawal from the crystallised, non-tax-free portion counts as taxable income for that tax year, added to any other income you have, such as the State Pension, part-time earnings, or other pensions, when working out how much tax you owe. Because you're managing an actively invested pot rather than a fixed contract, you or an adviser also need to keep reviewing the underlying investments, rebalancing as appropriate, and watching charges, since none of this happens automatically the way it does inside a guaranteed annuity.

The flexibility drawdown offers versus an annuity

The appeal of flexi-access drawdown is largely about control. With an annuity, you exchange your pot for a guaranteed income and, in most cases, that's the end of the decision — the amount is fixed, or fixed to rise with inflation if you chose that option, for the rest of your life, and you can't normally change your mind afterwards. Flexi-access drawdown works the opposite way: you can increase your withdrawals in a year when you need extra money for a big one-off cost, reduce them in a year when your investments have performed poorly, or stop taking an income altogether for a while if other income covers your needs. You can also change your underlying investment strategy over time, moving to more cautious funds as you get older, or adjusting risk levels if your circumstances change, none of which is possible once an annuity has been bought.

This flexibility also extends to what happens to your money when you die. Funds left in flexi-access drawdown can generally be passed on to your beneficiaries, often more efficiently than under many annuity structures, which typically stop paying out or reduce sharply on death unless you specifically paid for a guarantee period or joint-life option. That's a meaningful difference for people who want to preserve wealth for their family as well as fund their own retirement, and it's one of the reasons flexi-access drawdown has become so much more popular than annuities since the 2015 pension freedoms — though it's worth remembering that flexibility and death benefits come bundled with investment risk that an annuity simply doesn't carry.

The risks that come with that flexibility

Every benefit of flexi-access drawdown has a corresponding risk attached to it, and it's important to go in with eyes open. The most obvious is investment risk: because your pot stays invested, its value can fall as well as rise, particularly if markets have a poor run, and a sharp fall early in retirement can be much harder to recover from than the same fall would be for someone who isn't simultaneously drawing an income out of the pot, a problem known as sequencing risk, covered in more detail on our dedicated page. The second, related risk is simply running out of money. Because there's no cap on withdrawals, nothing stops you from drawing too much, too soon, particularly if you underestimate how long you might live or overestimate how well your investments will perform. Unlike an annuity, which guarantees an income for as long as you're alive no matter what happens to markets or how long you live, flexi-access drawdown offers no such guarantee — if the pot runs dry, the income stops.

There's also the practical burden of managing an actively invested pot through retirement, potentially for decades. Someone in drawdown needs to keep an eye on investment performance, rebalance their portfolio as their needs and risk appetite change, and decide how much to withdraw each year in light of all that — either doing this themselves or paying an adviser an ongoing fee to do it for them. Ongoing advice charges, and the underlying platform and fund charges of a drawdown product, can also erode returns over time in a way that's easy to overlook when comparing the headline flexibility of drawdown against the simplicity of an annuity. None of this makes flexi-access drawdown a bad choice — for many people it remains the right one — but it does mean the decision deserves careful thought, ideally with professional guidance, rather than being taken purely because it feels like the more modern or flexible option.

A worked example

Consider Margaret, 63, with a pension pot of £180,000. She decides to crystallise the whole pot at once. She takes her 25% tax-free lump sum, which comes to £45,000, moving the remaining £135,000 into a flexi-access drawdown fund, still invested in a mix of funds broadly similar to how it was invested before retirement. In her first year, Margaret decides she needs £7,000 of taxable income on top of her tax-free cash and her part-time earnings, so she asks her provider to pay this out over the course of the year. The following year, a larger-than-expected home repair bill comes up, so she draws £12,000 instead. In a third year, she takes nothing at all because her part-time work covers her costs. This is the essence of flexi-access drawdown: the income adapts to her circumstances, not the other way around, but it also means Margaret needs to keep checking that her withdrawals remain sustainable over the years ahead.

Who chooses flexi-access drawdown, and when it suits you

Flexi-access drawdown tends to suit people who have other resources or flexibility that reduce the risk of relying on it entirely — for example those with a reasonably funded pot, other guaranteed income such as a defined benefit pension or a healthy State Pension entitlement covering essential costs, or a willingness to adjust withdrawals if markets have a bad year. It also suits people who value being able to leave unused pension savings to their family, or who want to keep contributing to a pension after accessing some income, though note that taking taxable income from drawdown usually triggers the Money Purchase Annual Allowance, cutting your future contribution allowance to £10,000 a year — see our dedicated page on drawdown tax for the detail. It tends to suit people less well if they have no other income to fall back on, if they're uncomfortable with investment risk, or if peace of mind matters more to them than the potential for a larger income over time — in those cases, an annuity, or a blend of the two, may be a better fit. There's no single right answer, and increasingly savers choose a mixture: perhaps annuitising enough of a pot to cover essential bills, with the rest left in flexible drawdown for discretionary spending and growth potential. What matters is going in with a realistic understanding of both the freedom and the risk that flexi-access drawdown carries, rather than defaulting into it simply because it's now the most common choice.

It's also worth remembering that moving into flexi-access drawdown doesn't have to be all-or-nothing at outset. Many providers allow partial crystallisation, so you might crystallise only enough of your pot to meet an immediate need, perhaps to bridge the years before your State Pension starts, while leaving the rest uncrystallised and invested for later. This staged approach can also help manage the tax impact of large withdrawals, since spreading taxable income across several tax years, rather than taking it all in one go, can help you avoid being pushed into a higher tax band unnecessarily. Whichever approach you take, reviewing your drawdown arrangement at least once a year, checking investment performance, withdrawal sustainability, and whether your circumstances have changed, is generally considered good practice rather than an optional extra.

It's also worth planning for the tax mechanics of your very first withdrawal, since providers often apply an emergency tax code to the first taxable payment from a new drawdown arrangement, which can mean significantly more tax is deducted than is actually owed. This is usually corrected automatically within a tax year, or can be reclaimed directly from HMRC using the appropriate form, but it catches many people out precisely because they expect their first payment to match their planning exactly. Setting withdrawals up well in advance of when you actually need the money, and checking the tax code applied to your first payment, can help avoid an unwelcome and unnecessary cash-flow surprise in the months after you start drawing an income.

Charges are another area worth comparing carefully between providers before choosing where to hold a flexi-access drawdown arrangement. Platform fees, fund management charges, and any adviser charges are all deducted from the pot over time, and even a seemingly small difference of half a percentage point a year in total charges can make a noticeable difference to how long a pot lasts, especially over a retirement that could stretch for 25 years or more. It's generally worth asking any provider or adviser for a clear, all-in figure covering every layer of cost, rather than comparing headline platform fees alone, since additional fund-level charges can sometimes be easy to miss when shopping around.

Flexi-access drawdown decisions are usually irreversible once your pot is crystallised and investment strategies are set in motion — it's worth getting guidance from a regulated financial adviser, or free, impartial guidance from MoneyHelper, before committing a significant portion of your pension pot.
