Guaranteed Annuity Rates: The Pension Perk You Could Lose by Moving to Drawdown

Tucked away in the paperwork of some older pensions is a feature that can be worth tens of thousands of pounds over a retirement — a guaranteed annuity rate, or GAR. It is a contractual promise to turn your pension pot into a guaranteed income for life at a rate that can comfortably beat anything on the open market today.

Yet every year thousands of people give these guarantees up — often without realising they had one — when they move an old pension into flexible drawdown in search of more control over their money. Once it is gone, it is usually gone for good. If you are weighing up drawdown, this is one of the most important checks to make before you transfer a penny. Here is how guaranteed annuity rates work, why they can be so valuable, and what to look for.

What is a guaranteed annuity rate?

A guaranteed annuity rate is a promise written into certain older pension policies. It says that, at a specified age, you can convert your pension fund into a lifetime annuity at a minimum rate — no matter what annuity rates are doing in the wider market at the time.

Most GARs are found in personal pensions and retirement annuity contracts (sometimes called Section 226 or "s226" policies) sold mainly between the late 1970s and the 1990s. Back then interest rates were high, and providers built generous guaranteed rates into their contracts. Those rates stayed locked into the policy even as market annuity rates fell over the following decades.

The practical effect is simple. If your policy carries a 10% GAR, a £100,000 pot would buy you £10,000 of guaranteed income every year for the rest of your life. The provider has to honour that rate, even if no one else in the market comes close.

Why a GAR can be worth a small fortune

To see why these guarantees matter, compare them with what you can get today. As of June 2026, annuity rates are near their highest level in around 18 years — and yet the best open-market rate for a healthy 65-year-old buying a level, single-life annuity is roughly 7.8%, or about £7,800 a year per £100,000.

Now put a typical GAR next to that. Many older policies carry guaranteed rates of 9% to 11%, and some are higher still. Consider a £100,000 pot:

• With a 10% GAR: £10,000 a year, guaranteed for life.
• At today's best open-market rate (around 7.8%): roughly £7,800 a year.

That is a difference of about £2,200 every year — and it is guaranteed for as long as you live. Over a 20-year retirement, that gap adds up to roughly £44,000 in extra income, before you even account for the security of knowing the payments can never fall. Even on a more modest £40,000 pot, a 9% GAR pays £3,600 a year against around £3,120 on the open market — an extra £480 a year for doing nothing more than keeping a guarantee you already hold.

The catch: GARs come with conditions

Guaranteed annuity rates are valuable, but they are rarely a blank cheque. The guarantee almost always comes with strict conditions, and missing them can reduce or cancel it entirely. Common conditions include:

• A specific age. Many GARs only apply if you take your benefits at an exact age — often 65, sometimes 60 or another set date. Retire a year early or late and the guaranteed rate may no longer apply.
• A specific annuity shape. The guarantee is frequently based on a particular type of annuity — usually single life, paid level (with no annual increases), and sometimes with no guarantee period. If you want a joint-life annuity to protect a spouse, or one that rises with inflation, the GAR may shrink or fall away.
• Buying from the same provider. A GAR generally only applies if you buy your annuity from the provider that holds the policy. Transfer the pension elsewhere — or take it as drawdown — and the guarantee is usually lost.

This is exactly why GARs are so easy to forfeit by accident. The conditions are buried in decades-old paperwork, and the headline attractions of modern pensions — flexibility and choice — pull in the opposite direction.

How moving to drawdown can cost you the guarantee

Flexi-access drawdown is popular for good reasons. It lets you take income flexibly, keep your pot invested for potential growth, and pass on whatever is left to your loved ones, often very tax-efficiently. For many people, that flexibility is precisely what they want from retirement.

But here is the trap. To move an old pension into a modern drawdown plan, you normally have to transfer it — and transferring away from the provider that holds your GAR almost always means giving the guarantee up for good. You are effectively swapping a guaranteed, often above-market income for life in return for flexibility and investment risk.

That can be the right call for some people, but it should always be a conscious, informed decision — never an accidental by-product of chasing lower charges or a slicker app. Before you compare drawdown providers and start a transfer, check whether the pension you are about to move carries a guarantee you would be throwing away.

How to check whether you have a GAR

The frustrating truth is that providers do not always shout about guaranteed rates, and they can be hidden in dense policy documents. If you have an older pension, it is well worth doing some detective work:

1. Dig out the original policy documents and look for phrases such as "guaranteed annuity rate", "guaranteed annuity option" or "GAR".
2. Contact the provider directly and ask, in plain terms: "Does this policy include a guaranteed annuity rate, and if so, what is it and what conditions apply?"
3. Check your retirement or "wake-up" pack. Providers are required to send these as you approach retirement, and any safeguarded guarantee should be flagged within them.
4. Be especially alert if the pension is a personal pension or retirement annuity contract started before 2000 — that is the era when GARs were most common.

If a provider knows you hold a guarantee and you ask to give it up, they must send you a personalised risk warning showing the income the guarantee would provide compared with the alternative. Read it carefully — it exists precisely to stop people walking away from valuable rates by mistake.

Your legal protections — and the advice requirement

Guaranteed annuity rates are treated as a form of "safeguarded benefit" under UK pension rules, which brings an important protection. If the value of your safeguarded benefits is more than £30,000, you are legally required to take regulated financial advice before giving them up or transferring them away.

A few things are worth knowing here:

• Using your GAR to buy an annuity — even a slightly different shape — does not usually count as "giving it up", so the advice rule is aimed mainly at transfers and conversions to drawdown or cash.
• The government has been working to simplify how these guarantees are valued, which may mean fewer policies cross the £30,000 threshold in future — but the requirement for providers to send personalised risk warnings is set to remain.
• Even if your guarantee is worth less than £30,000, it is still worth getting guidance before you act. The free, government-backed services Pension Wise and MoneyHelper are good starting points.

Above all, remember that giving up a GAR is almost always irreversible. There is no "undo" button once a transfer goes through.

Is keeping the GAR always the right move?

Not necessarily — and this is where personal circumstances matter. There are sound reasons why some people decide a guaranteed rate is not for them:

• The shape does not suit you. If your GAR only guarantees a single-life, level income but you need to provide for a spouse or protect against inflation, the real-world value of the guarantee may be lower than the headline rate suggests.
• You want flexibility or to pass on your pot. An annuity income becomes less attractive if you value the ability to vary your income or leave the remaining fund to your family. Drawdown can offer valuable flexibility and death benefits that a guaranteed annuity cannot.
• Your health could buy you more elsewhere. If you have health conditions or lifestyle factors such as smoking, an enhanced annuity on the open market might, in some cases, rival or even beat a guaranteed rate.

The point is not that a GAR is always best — it is that you should never give one up without realising what you are giving up. A guarantee paying 9% or 10% a year is a serious financial asset, and the decision deserves proper thought.

Key takeaways

• A guaranteed annuity rate (GAR) is a contractual promise in some older pensions to convert your fund into a lifetime income at a minimum rate, regardless of market conditions.
• GARs are most common in personal pensions and retirement annuity contracts from the late 1970s to the 1990s, and often pay 9%–11% versus today's best open-market rates of around 7.8%.
• On a £100,000 pot, a 10% GAR could mean £2,200 a year more than the open market — roughly £44,000 extra over a 20-year retirement.
• Guarantees come with conditions (a set age, a set annuity shape, buying from the same provider) and are usually lost when you transfer to drawdown.
• If your safeguarded benefits exceed £30,000, you must take regulated advice before giving them up — and the decision is almost always irreversible.
