If you're married, in a civil partnership, or have a partner who depends on your income, one of the most important annuity decisions you'll make isn't about rates at all, it's about whether to buy a single life or a joint life annuity. A single life annuity pays only for as long as you live and then stops completely, however soon that is. A joint life annuity is built to protect two people: it continues paying an income, usually at a reduced percentage, to your surviving spouse or partner after you die. This page explains exactly how joint life annuities work, why they cost more in terms of a lower starting income, who should seriously consider one, and the choices involved in setting one up. Getting this decision right matters just as much as getting the annuity rate right, since it directly determines whether your household income survives your own death intact.
What a joint life annuity actually does
A joint life annuity is an annuity built around two named people rather than one. While both of you are alive, it pays the same kind of regular income as a single life annuity would. The difference only becomes apparent when the person who originally bought the annuity dies: instead of the income stopping altogether, as it would with a single life policy, a proportion of it, commonly 50% or 66%, though some policies offer 100%, continues to be paid to the named survivor for the rest of their life. This protects a spouse or partner from a sudden and total loss of that income at exactly the point in their life when they may be least able to cope with a financial shock, on top of the emotional impact of bereavement. It is, in effect, a form of built-in life insurance woven directly into the annuity's structure, funded by accepting a lower starting income from day one.
Why joint life annuities start lower than single life
The core reason a joint life annuity pays less to begin with, for exactly the same pension pot, is straightforward actuarial arithmetic. With a single life annuity, the insurer only has to plan for paying out over one person's remaining lifetime. With a joint life annuity, the insurer has to plan for paying out for as long as either person is alive, which, statistically, is a longer combined period than either individual's expected lifetime on its own. The insurer is effectively insuring two lives instead of one, and it prices the product accordingly, reducing the starting income to reflect the longer expected total payment period. The exact reduction depends on the percentage you choose to continue to the survivor and the age gap between the two of you; the larger the guaranteed continuing income and the bigger the age gap (particularly if the named survivor is significantly younger), the greater the reduction in starting income tends to be.
Single life versus joint life: a worked comparison
The table below illustrates, for a 65-year-old with a £100,000 pension pot and a same-age partner, roughly how the starting annual income might compare across single life and two common joint life options, using broadly illustrative approximate figures based on current market conditions. These are not personalised quotes; actual figures depend on both people's ages, health, and the specific insurer.
Who should seriously consider a joint life annuity
Anyone with a spouse, civil partner, or dependant who relies on their pension income, wholly or partly, to cover living costs should think very carefully before defaulting to a single life annuity purely to maximise their own headline income. If your partner has little pension income of their own, perhaps because they took time out of paid work to raise children or care for family, or worked part-time for much of their career, they could be left facing a serious and permanent drop in household income the moment you die, at exactly the point they may most need financial stability. A joint life annuity, even at a reduced 50% continuation, can make the difference between a surviving partner managing comfortably and one facing real financial hardship. It's worth having this conversation openly with your partner before buying, since it's ultimately a decision about both of your futures, not just your own.
The choices involved: percentage and who's covered
Buying a joint life annuity involves more than a single yes or no decision. First, you choose the continuation percentage, most commonly 50% or 66%, though 100% is available from many providers for those who want their partner's income completely unaffected by their death, in exchange for the lowest starting income of the three options. Second, you name who the joint life cover applies to; this is typically a spouse or civil partner, though many providers will also allow an unmarried partner or other financial dependant to be named, provided the relationship and financial dependency can be evidenced. It's important to name the right person accurately and to keep the insurer informed if your circumstances change, since a joint life annuity generally cannot be transferred to a different person after the event of remarriage or a new relationship; it is fixed to the person named when the policy was set up.
Joint life and other annuity features
A joint life option can be combined with the other choices covered on our "what is an annuity" page. You can still choose a level or increasing income, and add a guarantee period on top if you wish, though a guarantee period matters less for financial protection once a joint life feature is in place, since the surviving partner's income is already protected regardless of when the first death occurs. If you or your partner have a qualifying health condition, an enhanced joint life annuity may also be available, and how insurers assess this varies, since some take both people's health into account when calculating the enhanced rate, so it's worth reading our dedicated enhanced annuities page and disclosing both partners' health and lifestyle information when getting quotes.
The irreversibility of the choice
As with all standard annuities, the decision you make about single versus joint life, and the percentage you choose, is generally locked in for good once the policy is set up, beyond the standard short initial reflection period most providers offer. You cannot decide five years later that you'd prefer to add joint life cover to an existing single life annuity, and you cannot remove joint life cover from a policy to boost your own income if your relationship later ends. This makes it especially important to think through your family circumstances properly before buying, ideally with input from your partner and ideally with professional advice, rather than treating the joint life decision as a minor detail to be settled quickly at the point of purchase.
What happens if the survivor remarries or the relationship changes
Once a joint life annuity is in payment, the continuing income promised to the named survivor is generally unaffected by what happens in their life afterwards; if your spouse remarries after you die, for example, they typically continue receiving the joint life income regardless, since the payment is a contractual promise tied to the original policy rather than a benefit conditional on their circumstances. This is different from certain other survivor benefits, such as some final salary scheme spouse's pensions, which can occasionally include different rules; it's always worth checking your specific joint life annuity contract for the exact terms, but in general a joint life annuity income, once it starts, continues unconditionally for the rest of the survivor's life.
Thinking about death and pension planning more broadly
Deciding on a joint life annuity is one part of a much wider set of questions about what happens to your pension arrangements and finances when you die, including how any remaining drawdown funds, death-in-service benefits, or other assets pass to your family. Our dedicated page on what happens to your pension when you die covers this broader picture in more depth, and is worth reading alongside this page if you're planning your overall approach to protecting a partner or family financially.
How the age gap between partners affects the cost
One factor that surprises many people is how much a significant age gap between partners affects the pricing of a joint life annuity. If the named survivor is considerably younger than the annuity holder, the insurer has to plan for potentially paying the continuing income for many more years than it would for a same-age couple, since it's effectively insuring against a much longer combined lifespan. This means the starting income reduction for choosing joint life cover tends to be larger the bigger the age gap, and smaller when both partners are close in age. It's a factor worth discussing openly when getting quotes, since some providers price age gaps more generously than others, and a broker who compares the whole market can highlight where you'll get the best terms for your specific situation.
Why some people still choose single life deliberately
Joint life isn't automatically the right answer for everyone, even with a partner in the picture. Some couples have entirely separate finances and pension arrangements, with each partner holding a pension large enough to support themselves independently, in which case duplicating survivor protection through every pension may not add much value and simply reduces income unnecessarily. Others may already have substantial life insurance in place specifically to replace a partner's income on death, achieving a similar protective effect without permanently reducing the annuity income itself. And some people, single, divorced, or without a financially dependent partner, simply have no one who needs survivor protection at all, in which case a single life annuity, which maximises the income actually available during their lifetime, is usually the more sensible choice. The right answer always comes back to your specific family and financial circumstances rather than a one-size-fits-all rule.
A practical way to decide
A useful starting question is simple: if I died tomorrow, would my partner be able to maintain their standard of living without the income this annuity would have paid me? If the honest answer is no, or you're not sure, that's a strong signal that joint life cover, even at a modest 50% continuation, is worth the reduced starting income. It's also worth adding up your partner's own independent income sources, their own State Pension entitlement, any pension of their own, savings, or other assets, to get a realistic picture of the gap a joint life annuity would need to fill, rather than guessing. Couples who go through this exercise together, rather than one partner deciding unilaterally, tend to end up with an annuity structure that genuinely reflects both people's needs and expectations.
Estate and inheritance considerations
It's worth being clear that a joint life annuity is not the same thing as leaving an inheritance. Once the survivor also dies, or immediately in the case of a single life policy with no guarantee period, any remaining value simply ceases; there is no lump sum passed on to children or other beneficiaries through the annuity itself. If leaving money to family beyond a surviving spouse or partner is a priority for you, this is generally better achieved through other means, such as keeping some of your pension in drawdown (where unused funds can typically pass to any beneficiary you nominate, often efficiently from a tax perspective), other savings and investments, or life insurance written in an appropriate trust. Joint life cover and inheritance planning are two different goals, and it's worth being clear with yourself about which one you're actually trying to achieve with each part of your retirement planning.
Getting quotes for a joint life annuity
When requesting joint life annuity quotes, be ready to provide both people's dates of birth, and consider disclosing both partners' health and lifestyle information even if only one of you technically owns the pension pot, since as noted above some insurers factor both lives into the pricing of enhanced joint life annuities. It's worth obtaining quotes for more than one continuation percentage, for example both 50% and 66%, so you can see in concrete pounds and pence exactly what the trade-off looks like for your own pot size and ages, rather than deciding on a percentage in the abstract. As with any annuity purchase, comparing quotes from several providers through a broker who covers the whole of the market is likely to produce a noticeably better outcome than accepting a single, default quote.
