Drawdown or Annuity? The Same £300,000 Pension, Run Both Ways

Annuity rates are at their strongest since 2008, which reopens a decision many people assumed drawdown had already won. Here is the same pot, modelled two ways.

A plain-English, illustrative comparison of flexi-access drawdown versus an annuity on a £300,000 pension pot in 2026/27. Learn how each is taxed, who each tends to suit, why the hybrid approach is often the real answer, and how the April 2027 pension-IHT change affects what you leave behind.

Drawdown or Annuity? The Same £300,000 Pension, Run Both Ways

For most of the last decade, the smart money said annuities were finished. Rates were poor, drawdown gave you control, and locking your pension into a fixed income for life looked like a bad trade.

The reality in 2026 is different.

Annuity rates are the strongest they have been since roughly 2008. A decision a lot of people had quietly written off is suddenly worth running the numbers on again. So let's do exactly that: take one £300,000 pension pot and run it both ways, on the same day, for the same person.

The two routes lead to very different retirements. Neither is universally right. The point is to see the trade-off clearly before you commit to something you often cannot undo.

Drawdown and annuity, in plain English

Flexi-access drawdown means you keep your pension pot invested and draw a flexible income from it. You stay in control. The pot can grow or fall with markets, you can change your income each year, and whatever is left when you die passes to your heirs.

An annuity is the opposite trade. You hand your pot to an insurer, and in exchange they pay you a guaranteed income for the rest of your life, however long that turns out to be. No investment risk. No decisions to make each year. But on a basic single-life level annuity, when you die the income stops, and there is typically nothing left for your family.

One route sells certainty. The other keeps flexibility and control. Everything else is detail on top of that single trade-off.

Why "should I buy an annuity?" is a live question again

The reason this decision has reopened is simple: pricing.

A healthy 65-year-old can currently get roughly a 7% to 8% rate on a level single-life annuity. On a £300,000 pot, that is somewhere around £22,000 to £24,000 a year, guaranteed for life. Rates move daily and vary by provider, by your health, and by the options you bolt on, so treat those figures as "roughly," never as a quote. But the direction is real. Guaranteed income has not looked this attractive in over fifteen years.

That changes the maths against drawdown, where a cautious starting income has traditionally been closer to 4% of the pot. Which is exactly why it is worth putting both side by side.

The same £300,000, run both ways

Consider Margaret, 66, in England. She has a £300,000 SIPP (Self-Invested Personal Pension) and her full new State Pension of about £12,548 a year is already in payment. She is deciding what to do with the pot itself.

Here is how the same £300,000 breaks down two ways, on these assumptions. The annuity figure uses a level single-life rate of roughly 7.5%. The drawdown figure uses a 4% starting income. Both incomes are taxable in the same way, as income, on top of her State Pension.

On £300,000 Annuity (level, single-life) Drawdown
Income, year one ~£22,500/yr, guaranteed ~£12,000/yr (4% start)
Income certainty Fixed for life, never changes Depends on markets and your withdrawal rate
Investment risk None, carried by the insurer Yours. The pot can fall as well as rise
Inflation protection None on a level annuity. £22,500 buys less every year Possible if the pot grows, but not guaranteed
Flexibility to change None. The decision is permanent Full. Change income, pause it, take lump sums
Left for heirs Nothing, on a basic single-life level annuity The remaining pot (inside the estate for IHT from April 2027)
If she lives to 95 (29 years) ~£652,500 of income paid, still going Depends on returns. A 4% draw may last, but is not guaranteed
If she dies at 72 (6 years) ~£135,000 paid, the rest stays with the insurer Most of the pot passes to her heirs

Read the last two rows together and you have the whole decision in miniature. The annuity is a bet on a long life: live to 95 and it pays out more than double the pot. Drawdown is the better outcome if life is shorter, because what she does not spend, her family keeps. Nobody knows which line they are on, and that uncertainty is the real subject of this decision.

The nuances that change the answer

The table above is deliberately simple. Real annuities come with dials, and each one moves the numbers.

  • Level versus index-linked. A level annuity starts high and never rises, so inflation erodes its buying power year after year. An RPI-linked annuity protects against that, but it starts a lot lower, sometimes by a third or more. You are choosing between more money now and more protection later.
  • Single versus joint-life. A single-life annuity pays the most but stops entirely when you die. A joint-life annuity keeps paying a spouse or partner after your death, which matters enormously for a couple, but it pays less from day one.
  • The 25% tax-free cash sits under both routes. Before you annuitise or move into drawdown, you can normally take up to 25% of the pot tax-free, capped by the Lump Sum Allowance of £268,275. On £300,000 that is £75,000. Take it, and you would annuitise or draw down the remaining £225,000 instead. Leave it on the table and you hand more to the taxman than you need to.
  • Both incomes are taxed the same way. Neither route is a tax dodge. Annuity income and drawdown income are both taxable as income, stacked on top of your State Pension, against your Personal Allowance and the usual bands. Rates differ in Scotland.
  • The 4% rule is a rule of thumb, not a guarantee. Drawing a fixed percentage assumes an average that no single retirement actually follows. A poor run of returns in your early years, while you are also drawing income, can do lasting damage. A fixed rule is fragile precisely because markets are not.

And one row deserves a flag of its own. From 6 April 2027, most unused defined contribution pension pots will fall inside your estate for Inheritance Tax (IHT) at 40%. That reshapes the "left for heirs" line for drawdown, because the pot you were planning to pass on may now be taxed on the way through. It is a factual change worth planning around, not a reason to panic, and it is a topic in its own right.

The answer most people miss: you do not have to choose one

Here is what gets lost in a straight "drawdown or annuity" framing. For most people, the real answer is both.

The blended approach works like this. You annuitise just enough to cover your essential, non-negotiable spending, the bills that have to be paid whether markets are up or down. Your State Pension already does part of that job. A modest annuity on top can cover the rest. Then you keep the remainder of the pot in drawdown, invested, flexible, and available to your family.

For Margaret, that might mean a small annuity to top her guaranteed income up to the level of her essential outgoings, with the balance of the £300,000 left in drawdown for holidays, one-off costs, and whatever she wants to leave behind. She sleeps at night because the bills are covered no matter what. She keeps growth and control on the rest.

The hard part is not the concept. It is the number. How much to annuitise, how much to leave invested, and how that interacts with your State Pension timing, your tax bands, and how long you might live is a genuine optimisation problem, not a gut call.

This is exactly the kind of decision the UK version of Optiml is being built to model. On your own pot, your own State Pension, your own spending and longevity assumptions, it is designed to run drawdown, annuity, and every hybrid split in between, and show you the lifetime impact of each. Not a recommendation on which product to buy. The maths of your own trade-off, laid out so you can see it. Optiml plans, it does not pick your investments or your provider.

One caution worth stating plainly: giving up a guaranteed income, or transferring a defined benefit (final salary) pension to access drawdown, is a significant and often irreversible step that can require regulated financial advice. Investments can fall as well as rise. The goal of running the numbers is to walk into that decision with your eyes open, not to rush it.

Annuities were never really dead. They were just badly priced. Now that they are not, the honest answer to "drawdown or annuity?" is the one it always should have been: it depends on your numbers, and you deserve to see them.

Because retirement income isn't about picking a side. It's about knowing your own trade-off.
