Pension drawdown — technically called flexi-access drawdown — lets you take income from your pension pot while keeping the rest invested. Since pension freedoms were introduced in April 2015, it's become the most popular way to access defined contribution pensions, overtaking annuities. But flexibility comes with responsibility.
How drawdown works
When you enter drawdown, you move some or all of your pension pot into a drawdown arrangement. You can take up to 25% as a tax-free lump sum (either all at once or in stages), and the rest stays invested. You then draw income as you need it — monthly, quarterly, annually, or ad hoc. Each withdrawal beyond the tax-free portion is taxed as income at your marginal rate.
Your money remains invested throughout, which means it can continue to grow. But it can also fall in value. Unlike an annuity, there's no guarantee that your money will last as long as you do.
Tax on drawdown withdrawals
The first 25% of each pension pot is tax-free. Everything above that is taxed as income. The rate depends on your total taxable income for the year:
If your only income is from drawdown, you can withdraw up to the Personal Allowance (£12,570 in 2025/26) tax-free each year, on top of the 25% tax-free element. Careful planning of withdrawal amounts can minimise your tax bill significantly.
A common mistake is taking a large lump sum in a single tax year, which pushes you into a higher tax bracket. Spreading withdrawals across multiple tax years can save thousands in tax. If you take a large withdrawal, your provider applies an emergency tax code — you may pay too much tax initially and need to reclaim it from HMRC.
How much can you safely withdraw?
This is the critical question, and there's no single right answer. The commonly cited "4% rule" — withdrawing 4% of your initial pot each year, adjusted for inflation — originated from US research and assumes a specific portfolio mix and time horizon. It's a reasonable starting point but not a guarantee.
What matters is your personal situation: how large is your pot, what other income do you have (State Pension, rental income, other pensions), how long do you expect to live, and what returns can you reasonably expect from your investments?
Some financial planners use "natural yield" — only taking the income (dividends and interest) generated by investments without touching the capital. This is more conservative but may provide less income than you need.
Drawdown vs annuity
An annuity gives you a guaranteed income for life in exchange for handing over your pension pot (or part of it) to an insurance company. Drawdown keeps you in control but carries investment and longevity risk.
Annuity advantages: guaranteed income regardless of how long you live, no investment decisions to make, predictable budgeting.
Drawdown advantages: flexibility to vary income, potential for growth, ability to pass remaining funds to beneficiaries, control over your investments.
You don't have to choose one or the other. Many people use drawdown in early retirement when they're more active and want flexibility, then buy an annuity later (perhaps at 75 or 80) to secure a guaranteed income for the rest of their life. Annuity rates tend to improve with age, so waiting can mean better value.
Investment strategy in drawdown
The biggest risk in drawdown is sequence-of-returns risk — if markets fall heavily in your early years of drawdown while you're withdrawing income, the double impact of losses plus withdrawals can permanently damage your pot. Recovering from a 30% drop while also taking income is much harder than recovering from the same drop during the accumulation phase.
To manage this, many people keep one to three years' worth of income in cash or low-risk investments, drawing from this during market downturns rather than selling investments at depressed prices. The rest remains in growth assets. This cash buffer approach doesn't eliminate risk but provides a cushion.
Charges in drawdown
Drawdown charges typically include the platform fee, fund charges, and sometimes a drawdown administration fee. These come from the same providers as SIPPs — AJ Bell, Hargreaves Lansdown, Interactive Investor, Vanguard, and others. Compare total costs carefully, as even small differences compound over what could be a 30+ year drawdown period.
Monitoring and reviewing
Drawdown isn't a set-and-forget arrangement. You need to review your withdrawal rate, investment performance, and remaining pot regularly — at least annually. If markets have fallen or you're withdrawing more than planned, you may need to adjust. Some people engage a financial adviser specifically for drawdown planning, and the cost can be well worth it for the peace of mind and expertise.
The FCA has expressed concern about people entering drawdown without advice and running out of money. If your pension pot is your primary source of retirement income, getting professional advice at least once is a sensible investment in your future security.
