Joint vs Single Life Insurance: Which Is Better for Couples?

Joint life insurance covers two people on one policy and pays out once, usually when the first person dies. Two single policies cover each partner separately and can pay out twice. A joint policy is often slightly cheaper, but single policies give more protection and are simpler if you ever separate.

Most couples buying a home together assume a joint policy is the obvious choice. It often is not. This guide compares the two side by side so you can decide which suits your household.

How does joint life insurance work?

A joint life first death policy covers both partners. When the first partner dies during the term, it pays out and then ends. The surviving partner is left with no cover from that policy. MoneyHelper explains the main types of life cover and how they pay out (MoneyHelper).

There is also joint life second death cover, which pays out when the second partner dies. This is mainly used with whole of life insurance to pay an inheritance tax bill, because married couples and civil partners can usually pass assets to each other free of inheritance tax on the first death (GOV.UK).

For most couples buying a home, the choice is between joint life first death and two single policies.

How do two single policies work?

Each partner takes their own policy. If one partner dies, their policy pays out. The other partner’s policy carries on, so they are still covered. If both partners died during the term, both policies would pay.

Is joint life insurance cheaper?

Usually, yes, but often by less than people expect. A joint policy is cheaper because the insurer only pays once. Two single policies cost a little more, but for that difference you get up to twice the protection and cover that survives a claim.

The best way to decide is to see both prices side by side for your ages, health, amount and term. We do that as standard.

What happens to the surviving partner?

This is the biggest drawback of joint cover. After a claim, the surviving partner has no life insurance from that policy. They may now be a single parent with a mortgage, and older, so new cover could cost much more. If their health has changed, they might struggle to get cover at all.

With two single policies, the survivor still has their own cover in place at the price they locked in when they started.

What if you separate?

A joint policy can be awkward if you split up. You may have to cancel it and each apply for new cover, at your new ages and current health. Some insurers offer a separation option that lets you split a joint policy into two single policies without new medical questions, within set rules, so check the wording.

With two single policies, each partner simply keeps their own. They can update the beneficiaries or trust as needed.

When does a joint policy make sense?

A joint policy can still be the right choice when:

• the only aim is to clear a shared mortgage on the first death
• the budget is tight, and one joint policy is affordable while two singles are not
• you are married with a stable relationship and are happy that the survivor would arrange new cover if needed
• you want second death cover for inheritance tax planning.

When are single policies better?

Two single policies are usually better when:

• you have children, and the survivor would need cover too
• you earn very different amounts, and want different sums or terms
• you are not married, or one of you has children from a previous relationship
• you want the most protection for a small extra cost.

Can you have different amounts on single policies?

Yes, and this is one of their biggest advantages. If one partner earns most of the income, they may need more cover. If one partner is the main carer for the children, their cover needs to pay for childcare and help at home if they died. Single policies let you set the right amount and term for each person. See our guide to how much life insurance you need.

Joint or single cover and trusts

Both can be written in trust. A single policy is usually simplest. A joint first death policy needs a particular type of trust, often called a survivorship trust, so the money goes to the surviving partner, or into trust if you both die together. See our guide to life insurance in trust.

What about critical illness cover?

The same choice applies to critical illness cover. A joint critical illness policy pays once, on the first diagnosis or death, then ends. With single policies, the partner who has not claimed keeps their cover. Because critical illness is more common than death during a mortgage term, this difference can matter even more.
