Pension Drawdown vs Annuity: Which Should You Ch

When I hit 40 and walked away from Kaizen, the pension question landed on my desk earlier than it does for most people. I had a SIPP, a couple of old workplace pots, and a decision to make about how I would eventually turn those pots into an income. Not at 40 (my ISAs cover the bridge years), but at 57 when I can finally access them.

The choice boils down to two options: pension drawdown or an annuity. One gives you flexibility. The other gives you certainty. And the right answer depends entirely on who you are, how much you have, and how comfortable you are with investment risk.

What is pension drawdown?

Pension drawdown (sometimes called flexi-access drawdown) lets you keep your pension pot invested while taking an income from it. Your money stays in the market, hopefully growing, and you withdraw what you need when you need it.

You can take 25% of your pot tax-free upfront (or in chunks), and the rest is taxed as income when you withdraw it. There is no fixed amount you have to take each year. You could draw £10,000 one year and £30,000 the next. It is entirely up to you.

The pot does not stop working just because you have retired. If your investments return 6% and you only draw 4%, the pot grows. That is the appeal. You are not handing your money over to an insurance company. You still own it. You still control it.

The risks are real though. If markets crash in the early years of your retirement and you are drawing income at the same time, your pot can shrink fast. This is called sequence of returns risk, and it has genuinely destroyed retirement plans. A 30% drop in year one of drawdown is far more damaging than a 30% drop in year ten.

What is an annuity?

An annuity is simpler. You hand your pension pot (or part of it) to an insurance company, and they pay you a guaranteed income for the rest of your life. You never run out of money. You never worry about markets. You just receive your payment every month until you die.

The amount you get depends on your age, your health, the size of your pot, and the interest rate environment when you buy. As of late 2025, a 65-year-old in average health can expect roughly £5,500 per year for every £100,000 used to buy a level annuity. If you are in poor health, you might get more through an enhanced annuity, because the insurance company expects to pay out for fewer years.

Once you buy an annuity, the decision is made. The money belongs to the insurance company. If you die a year later, it is gone (unless you bought a guarantee period or a joint life annuity, which reduce your payout).

The case for drawdown

Drawdown suits you if:

You have a larger pension pot. A pot of £300,000 or more gives you enough buffer to ride out market downturns while still drawing an income. Smaller pots are more vulnerable.
You are comfortable with investment risk. If watching your pot fluctuate by 10% or 20% in a bad year would keep you up at night, drawdown is not for you.
You want flexibility. Maybe some years you need more income (a big holiday, home renovations), and other years you need less. Drawdown allows that. An annuity does not.
You want to leave an inheritance. With drawdown, whatever is left in your pot when you die passes to your beneficiaries. With an annuity, it is gone.
You are retiring early. Buying an annuity at 57 locks in a lower rate than buying one at 70 or 75. If you retire young, drawdown gives you time to let the pot grow before potentially buying an annuity later.

The case for an annuity

An annuity suits you if:

You want certainty above everything. You want to know exactly how much lands in your account every month, regardless of what markets do. That peace of mind has real value.
You have no interest in managing investments. Not everyone wants to think about asset allocation in their 70s. An annuity removes that burden completely.
You are later in life. Annuity rates improve significantly as you age. Buying at 75 gives you a much better deal than buying at 57. The insurance company expects to pay out for fewer years, so each payment is larger.
You have a smaller pot. If your pension is £80,000, a market crash could halve it. An annuity removes that risk entirely and gives you a predictable floor of income.
Your health is poor. Enhanced annuities pay more to people with health conditions. If you have diabetes, heart disease, or other qualifying conditions, you could get 20% to 40% more income than the standard rate.

The hybrid approach (and why it makes sense for most people)

Here is what I think most people should actually do, and what I plan to do when I reach 57.

Use an annuity to cover your essential spending. The mortgage, council tax, food, utilities, insurance. The bills that arrive every month regardless. Buy enough guaranteed income to cover those, and you never have to worry about keeping the lights on.

Then keep the rest in drawdown for everything else. Holidays, hobbies, gifts, the fun stuff. If markets have a bad year, you tighten the discretionary spending. Your essentials are already covered.

This hybrid approach gives you the security of an annuity and the flexibility of drawdown. You get a guaranteed floor with an uncapped ceiling.

The maths might look like this. Say your essentials are £15,000 a year and your total pension pot at 65 is £400,000. You could use roughly £270,000 to buy an annuity covering your essentials (at £5,500 per £100K). The remaining £130,000 stays in drawdown, invested, growing, and available to top up your lifestyle.

Why I chose drawdown (for now)

I retired at 40. My pension is locked until 57. Even then, buying an annuity at 57 would give me a poor rate because I am (hopefully) going to live for another 30+ years. The insurance company prices that in.

So my plan is drawdown from 57, with the option to buy a partial annuity later in life when the rates are better and my need for certainty is higher. At 57, I still have the appetite and the knowledge to manage my investments. At 75, I might not. That is when an annuity starts to look more attractive.

I also want to pass my pension on to my kids. With drawdown, I can. With an annuity, I cannot (unless I pay extra for a guarantee period, which reduces the income).

Three things to do before you decide

Work out your essential spending. Before you choose between drawdown and an annuity, you need to know what your non-negotiable monthly costs are. That number determines how much guaranteed income you actually need.
Get an annuity quote. Use the Money Helper annuity comparison tool or speak to a broker. See what your pot would actually buy you. The number might be higher (or lower) than you expect.
Consider your health honestly. If you have health conditions, an enhanced annuity could give you significantly more income. It feels uncomfortable to benefit from poor health, but ignoring it means leaving money on the table.

This is one of the biggest financial decisions you will ever make, and it is not reversible if you choose an annuity. Take your time. Run the numbers. And if your pot is large enough, do both.
