TL;DR
Joint life insurance covers two people on one policy and usually pays out once, on the first death. It is often a little cheaper than two single policies, but two single policies pay out twice and are easier to split if you separate. This guide explains how joint cover works, what it costs and when two single policies may be the better choice.
Key takeaways
- A joint life first death policy pays out once, when the first person dies, and then ends.
- Joint cover is usually cheaper than two single policies, but often not by much.
- Two single policies can pay out twice, which can leave the surviving partner better protected.
- Separating or divorcing is simpler with single policies, which can each be kept on their own.
- Joint cover is common for couples with a shared repayment mortgage.
Joint life insurance covers two people, usually partners, under one policy with one premium. It is a common way for couples to protect a mortgage or a family's finances. Before choosing it, though, it is worth comparing it with two single policies, because the difference in how they pay out can matter more than the difference in price.
How joint life insurance works
Most joint policies are joint life, first death policies:
- The policy covers both of you.
- It pays out once, when the first person dies during the term.
- The policy then ends, so the surviving partner has no cover unless they take out a new policy, which may cost more because they are older.
Less commonly, a joint life, second death policy pays out only after both people have died. These are mainly used with whole of life cover for inheritance tax planning.
Joint cover can be level (the payout stays the same) or decreasing (the payout falls, roughly in line with a repayment mortgage).
How much does joint life insurance cost?
The premium depends on both people's ages, health and smoking status, the amount of cover, the term and whether the cover is level or decreasing. A joint policy is usually somewhat cheaper than two single policies for the same amount of cover each, but the saving is often modest.
For a guide to single-life prices, Which? found in April 2026 that £200,000 of level term cover over 25 years averaged about £8.20 a month for a 31-year-old non-smoker and £16.20 at 41. See term life insurance prices by age and joint vs single policy costs.
Joint policy or two single policies?
| Joint life, first death | Two single policies | |
|---|---|---|
| Number of payouts | One | Up to two |
| Cost | Usually a little cheaper | Usually a little more |
| Cover after first death | Ends | Surviving partner's policy continues |
| If you separate | Must usually be cancelled or kept jointly | Each person keeps their own |
| Different terms or amounts | Not possible | Each policy can be set up differently |
| Writing in trust | Possible | Possible, and often simpler |
When joint cover can make sense
- You mainly want to repay a shared mortgage if either of you dies.
- Keeping the premium as low as possible matters most.
- You are both comfortable with only one payout.
When two single policies can be better
- You want the surviving partner to keep cover after the first death.
- You have children and want the maximum protection.
- You want different amounts or terms for each person, for example because one earns more.
- You want flexibility if your relationship changes.
What about critical illness cover?
Joint policies can include critical illness cover, which pays out on diagnosis of a covered serious illness. As with life cover, a joint critical illness policy usually pays out once. See life insurance with critical illness cover.
Writing joint life insurance in trust
A joint first death policy usually pays the surviving partner directly, so a trust is often less important than for a single policy. A trust can still help if both people could die together, or if you want the money to go to children. See life insurance in trust.
