Pension drawdown UK — how it works and is it right for you?

Pension drawdown — sometimes called flexi-access drawdown — is a way of taking income from your pension pot in retirement while keeping the remaining money invested. Instead of converting your entire pension into a guaranteed income (an annuity) when you retire, drawdown allows you to leave your pension invested and withdraw money as and when you need it, with complete flexibility over the amounts and timing.

Drawdown became the most common way to access pension savings in the UK following the pension freedoms introduced in April 2015, which gave people with defined contribution pensions far greater flexibility over how they access their money.

How does pension drawdown work?

When you enter drawdown, your pension pot remains invested — typically in a range of funds chosen by you or your adviser. You can take withdrawals from the pot at any time and in any amount, subject to your provider's terms. Each withdrawal is made up of two parts: 25% is tax-free (as part of your Pension Commencement Lump Sum entitlement) and 75% is taxable as income in the year you receive it.

The tax-free element works slightly differently depending on how you access your tax-free cash. Some people take the full 25% of their pot as a tax-free lump sum at the outset and enter drawdown with the remaining 75%. Others prefer to crystallise smaller amounts over time, taking 25% of each withdrawal tax-free — this is sometimes called uncrystallised funds pension lump sum (UFPLS). The rules are complex, and a financial adviser can help you understand the most tax-efficient approach for your circumstances.

What are the advantages of drawdown?

Drawdown offers several significant advantages over buying an annuity. Flexibility is the most obvious — you can vary your withdrawals up and down depending on your needs in any given year, rather than being locked into a fixed income. Your remaining pot continues to be invested, which means it has the potential to grow and provide a higher income in later years. If you die before exhausting your pot, any remaining funds can usually be passed on to your beneficiaries, potentially free of inheritance tax depending on the circumstances. And you retain control over where your money is invested.

What are the risks of drawdown?

Drawdown also carries significant risks that are not present with an annuity. The most serious is the risk of running out of money — sometimes called longevity risk. If you withdraw too much too quickly, or if your investments perform poorly, your pot could be exhausted before you die. Unlike an annuity, there is no guaranteed income for life. Investment risk is also real — your remaining pot can fall in value, particularly in market downturns, which can be especially damaging if they occur early in retirement when the pot is at its largest (a phenomenon known as sequence of returns risk). Managing drawdown sustainably requires ongoing attention and, ideally, professional guidance.

Drawdown vs annuity

The choice between drawdown and an annuity is one of the most important financial decisions many people face at retirement. An annuity provides certainty — a guaranteed income for life regardless of how long you live or what markets do — but once purchased is irreversible and offers no flexibility. Drawdown provides flexibility and the potential for growth but requires active management and carries the risk of the pot running out.

Many people choose a combination — using part of their pot to buy an annuity (providing a guaranteed income floor) and putting the rest into drawdown (providing flexibility and growth potential). The right balance depends on your health, other income sources, attitude to risk, and personal preferences.

The importance of financial advice

The decisions involved in pension drawdown — how much to withdraw, what to invest in, how to manage sequence of returns risk, and how to balance drawdown against other income sources — are genuinely complex. The FCA strongly encourages people to take regulated financial advice before entering drawdown, and for pension pots of any significant size, this advice is likely to pay for itself many times over in avoided mistakes.
