Pension Annuity: Guaranteed Income for Life Explained

A pension annuity is a financial product you buy with some or all of your defined contribution pension pot, in exchange for a guaranteed regular income. That income is usually paid for the rest of your life, regardless of how long you live or what happens in the financial markets. Once purchased, the arrangement is almost always irreversible, which is why the decision deserves careful thought.

You can typically buy an annuity from age 55 (rising to 57 from April 2028). Before purchasing, most people choose to take up to 25% of their pension pot as a tax-free lump sum, then use some or all of the remainder to buy their annuity.

Annuities are sold by insurance companies, not by pension providers. This is an important distinction because it means you have the legal right, known as the Open Market Option, to shop around and compare quotes from any annuity provider on the market. You are not restricted to your current pension provider's offer, and shopping around frequently results in a noticeably higher income.

Understanding how pensions work and the type of personal pension you hold will help you assess whether an annuity is the right choice for your circumstances.

Turning your pension savings into annuity income follows a clear sequence, though the decision itself requires careful thought because it is usually permanent.

1. Build your pension pot through workplace or personal contributions during your working life.
2. Reach the minimum pension age, currently 55 and rising to 57 from April 2028.
3. Take up to 25% as tax-free cash if you wish, before using the remainder to purchase your annuity.
4. Shop around for quotes using the Open Market Option, comparing rates from multiple insurance companies.
5. Choose your annuity type: single or joint life, level or escalating, with or without a guarantee period.
6. Buy your annuity by transferring your chosen amount to the insurer.
7. Receive guaranteed income for life or for a fixed term, depending on the product you selected.

Once the annuity is in payment, your income is locked in. A level annuity pays the same amount each year. An escalating annuity increases annually by a fixed percentage or in line with inflation, though the starting income will be lower. The fundamental trade-off is certainty versus flexibility: an annuity removes investment risk and longevity risk entirely, but you give up access to your capital permanently.

Several types of annuity are available, each designed for different retirement priorities. Understanding the differences before you commit is essential, because you generally cannot change the terms once the annuity is in payment.

Lifetime annuity

The most common type. You hand over a lump sum and receive a guaranteed income for the rest of your life, regardless of how long you live. This is the standard choice for people who value certainty and want to cover essential living costs without worrying about investment performance or market volatility.

Fixed-term annuity

Pays a guaranteed income for a set period, typically 5 to 25 years, rather than for life. At the end of the term you receive a maturity amount that you can use to buy another annuity, move into drawdown, or take as cash. This suits people who want guaranteed income now but wish to reassess their options later, perhaps because they expect annuity rates to improve.

Enhanced or impaired-life annuity

If you have a health condition, smoke, or take certain medications, an enhanced annuity could pay significantly more than a standard rate. Uplifts of 20% to 40% are not uncommon for qualifying conditions. Diabetes, heart disease, high blood pressure, high cholesterol, and some cancers commonly qualify. Always disclose your full medical history and lifestyle when requesting quotes, as failing to do so means you may miss out on a substantially higher income.

Joint-life annuity

Continues paying an income to your spouse or partner after you die, usually at a reduced rate such as 50% or 66% of the original amount. This provides financial protection for a surviving partner but means a lower starting income compared with a single-life annuity. Consider whether life insurance might be a more cost-effective way to protect your partner's finances in some situations.

Level vs escalating annuity

A level annuity pays the same amount every year. An escalating annuity starts lower but increases annually, either by a fixed percentage (commonly 3%) or in line with inflation (RPI or CPI). Over a long retirement of 25 years or more, an escalating annuity typically pays more in total, but it can take 10 to 15 years for the cumulative payments to overtake the level option.

The income a pension annuity pays depends on several factors: your age at purchase, the size of your pot, current annuity rates, the type of annuity you choose, and your health. Older buyers generally receive higher rates because the insurer expects to pay out for fewer years.

The table below shows illustrative annual income from a standard single-life, level annuity with no guarantee period, based on approximate UK market rates. These figures are for illustration only and are not a quote. Actual rates vary by provider and change frequently with gilt yields and interest rate movements.

These figures assume the entire pot is used to purchase the annuity, with no tax-free lump sum taken first. If you take 25% tax-free cash beforehand, the annuity income would be roughly 75% of the amounts shown above.

Several factors could increase or decrease your actual income. An enhanced annuity for a qualifying health condition could add 20% to 40% to these figures. Choosing a joint-life annuity, an escalating annuity, or adding a guarantee period would each reduce the starting income. Rates also vary significantly between providers, so always obtain quotes from at least five or six insurers rather than accepting your existing pension provider's offer. The gap between the highest and lowest quotes on the market can exceed 20%, which on a £200,000 pot could mean a difference of more than £2,000 per year for the rest of your life.

When you reach retirement, you have three main ways to access your defined contribution pension savings. Each carries different levels of risk, flexibility, and tax treatment, and understanding how they compare is essential before committing to any single approach.

A pension annuity gives you a guaranteed income for life. You hand over your pot, or part of it, and the insurance company takes on all the investment risk and longevity risk. Your income is fixed and predictable, but you permanently lose access to your capital.

Pension drawdown keeps your pot invested while you take a flexible income from it. You control how much you withdraw and when, and your remaining funds can continue to grow. However, your pot is exposed to investment risk. If markets perform poorly or you withdraw too quickly, you could run out of money in later life.

An uncrystallised funds pension lump sum (UFPLS), sometimes called taking a pension lump sum, lets you withdraw cash directly from your pot. Each withdrawal is 25% tax-free and 75% taxable income. This is the simplest option but offers no guaranteed income, and large withdrawals can push you into a higher tax bracket.

You do not have to choose just one option. Many people use a combination: buying an annuity to cover essential bills, keeping part of their pot in drawdown for flexibility, and taking a lump sum for immediate spending needs.

Buying an annuity is one of the most significant financial decisions you will make, and it is usually irreversible. Following a structured process helps ensure you do not leave money on the table by accepting the first offer you receive.

1. Check your pension pot value. Contact your provider for an up-to-date valuation. Ask specifically about any exit fees, guaranteed annuity rates, or other valuable features attached to your policy. A guaranteed annuity rate from an older policy may be worth more than anything available on the open market today.
2. Decide on tax-free cash. You can take up to 25% of your pot tax-free before using the rest to buy an annuity. Consider whether you need the cash now or whether a larger annuity income would serve you better over the long term.
3. Choose your annuity options. Decide between single-life or joint-life, level or escalating payments, and whether to include a guarantee period of 5 or 10 years.
4. Get quotes using the Open Market Option. You are legally entitled to buy from any provider, not just your current pension company. Obtain quotes from at least five or six insurers. Online annuity comparison services can help you gather multiple quotes quickly and at no cost.
5. Disclose your health and lifestyle honestly. Smoking, medical conditions, regular medications, and even your postcode can qualify you for an enhanced rate. Failing to disclose relevant information means you may miss out on a significantly higher income for the rest of your life.
6. Compare and apply. Look carefully at annual income, any charges, and the terms of any guarantee period. Once you are satisfied, complete the application with your chosen provider.
7. Use your cooling-off period. You have 30 days after purchase to cancel and get your money back if you change your mind.

Use a pension calculator to estimate how much retirement income you will need before shopping for quotes. If you have multiple small pension pots spread across different providers, consolidating your pensions before buying could simplify the process and potentially improve your negotiating position.

Whether an annuity suits your retirement depends on your priorities, health, other income sources, and how comfortable you are managing investments. Here are the scenarios where an annuity tends to work well, and where it may not be the best fit.

An annuity may suit you if

• You want a guaranteed income to cover essential bills such as housing costs, utilities, and food, regardless of what happens in financial markets
• You are in good health and expect a long retirement, meaning you are likely to receive payments for many years
• You do not want the responsibility of managing investments or monitoring withdrawal rates in drawdown
• You have other sources of flexible income alongside the annuity, such as a drawdown pot, ISA savings, or rental income

An annuity may not suit you if

• You have a serious health condition that significantly reduces your life expectancy (though check enhanced rates first, as these could work in your favour)
• You want flexibility to vary your income from year to year based on changing needs
• You want to leave your pension pot to your beneficiaries, as a standard annuity typically ends when you die
• You have a very small pot that would produce only a minimal annual income

How pension annuity income is taxed

Annuity income is taxed as earned income through PAYE, just like a salary. It is added to any other taxable income you receive, including the State Pension, and taxed at your marginal rate. The 25% tax-free element applies to the lump sum you can take before buying the annuity, not to the ongoing annuity payments. If your total annual income stays within the personal allowance (£12,570 for the 2025/26 tax year), you will not pay income tax on your annuity income. Above that threshold, standard income tax bands apply. Learn more about pension tax relief and how it interacts with your retirement income planning.

What happens to a pension annuity when you die

What happens depends on the type of annuity you purchased. A standard single-life annuity with no guarantee period stops paying when you die, and nothing passes to your estate or beneficiaries. If you chose a joint-life annuity, payments continue to your nominated partner at a reduced rate (typically 50% or 66%). If you included a guarantee period of 5 or 10 years, payments continue to your beneficiaries until the guarantee period ends, even if you die before that point. Value protection is another option that returns the difference between what you originally paid for the annuity and the total paid out so far. For homeowners with a smaller pension pot, equity release may be worth considering as an alternative or supplement to annuity income rather than stretching a small pot across a lifetime annuity purchase.
