How does pension drawdown work?



Pension drawdown is one of the main ways people access their pension in the UK.


This guide explains pension drawdown how it works UK rules, so you can understand the tax, flexibility, and long-term impact before making decisions.


It allows you to keep your pension invested while taking money from it over time, rather than converting it into a guaranteed income straight away.


Understanding how pension drawdown works can help you see how flexible it is, and what the main trade-offs are, before deciding how to use it.


In the UK, drawdown rules are flexible, but how much you withdraw and how your pension is invested can significantly affect how long it lasts.


What is pension drawdown?

Pension drawdown, sometimes called flexi-access drawdown, allows you to:

  • move your pension into a drawdown arrangement

  • keep the money invested

  • withdraw income or lump sums when you choose

There is usually no fixed limit on how much you can take each year, as long as there is money left in the pension.


When can you use pension drawdown?

Most people can access pension drawdown from age 55, rising to 57 from 2028.

Once you reach the minimum pension age, drawdown becomes one of the standard options for taking money from a defined contribution pension.


How withdrawals are taxed

When using pension drawdown:

  • up to 25% of your pension can usually be taken tax-free

  • the remaining 75% is taxed as income when you withdraw it

You can take the tax-free amount all at once, or in stages alongside taxable withdrawals.

Taking larger withdrawals in a single tax year can increase the amount of income tax you pay.


A simple example


Imagine a pension worth £400,000.

If £100,000 is taken as tax-free cash, £300,000 remains invested in drawdown.

If you then withdraw £20,000 per year as income:

  • that £20,000 is treated as taxable income in that year

  • the tax paid depends on your other income and available allowances

  • the remaining pension stays invested and may rise or fall in value

This illustrates the central balance in drawdown: flexibility today affects sustainability tomorrow.


How flexible is pension drawdown?

Drawdown is considered flexible because:

  • you choose when to take money

  • you decide how much to withdraw

  • withdrawals can change from year to year

This flexibility can help when income needs vary over time.

However, flexibility also means there is no guaranteed income, and future payments depend on how long the pension lasts.


What happens to the pension money you don’t withdraw?

Any money not withdrawn through drawdown:

  • remains invested

  • rises or falls depending on investment performance

This creates two key risks:

  • investment risk, where values can fall as well as rise

  • longevity risk, the possibility of running out of money later in life


How drawdown compares with other pension options

Pension drawdown is often compared with:

  • taking lump sums, which may increase tax in a single year

  • buying an annuity, which provides certainty but less flexibility

Each approach involves trade-offs between flexibility, certainty, tax, and long-term sustainability.


What happens if the pension runs out?

If all the money in a drawdown pension is withdrawn, or investment performance reduces it to zero, no further income can be taken from that pension.

This is why many people consider how withdrawal levels and investment strategy interact over time, rather than viewing drawdown as income alone.


Common questions about pension drawdown and how it works in the UK


Can you take all of your pension using drawdown?In many cases you can withdraw the full value over time, but anything beyond the tax-free portion is normally taxed as income in the year it is taken.

Is pension drawdown risky?Drawdown involves investment and longevity risk. The pension value can fall, and withdrawals that are too high may reduce how long the money lasts.

Can you change the amount you withdraw each year?Yes. One of the main features of drawdown is flexibility, allowing withdrawals to increase, decrease, or stop depending on circumstances.

Is drawdown better than an annuity?Neither option is universally better. Drawdown offers flexibility and investment exposure, while annuities provide certainty of income. The appropriate choice depends on personal priorities and risk tolerance.


A final thought before deciding

This article explains how pension drawdown works in general, not whether it is suitable for you.


For many people, the more important step is not choosing immediately, but understanding how today’s withdrawal decisions shape future security.
