Is the cheapest option always best? Joint vs single life policies
This article first appeared in Professional Paraplanner in July 2026.
When supporting clients who are considering life insurance or critical illness cover, one of the early decisions advisers help make is whether to put cover in place on a joint or single-life basis. While cost is often the primary driver, and there is usually only a minimal difference, the choice can have implications far beyond the monthly premium.
The example below illustrates the difference in monthly costs between the two approaches.
Mark and Jayne, both aged 34, non-smokers, level term policy, sum assured £150,000 over 25 years (Royal London quote June 2026):
- Joint life first event policy: £13.80 + £2.60 plan fee = £16.40
- Two single life policies (individually owned): £7.07 + £7.07 + £2.60 plan fee = £16.74
For financial advisers, understanding the advantages and disadvantages of each approach is essential to ensuring recommendations remain suitable not only today, but throughout a client’s lifetime.
The case for joint life policies
Joint life policies have long been popular among couples, particularly those seeking protection for a mortgage or shared financial commitments.
| Advantages | Disadvantages |
|
Lower cost In many cases, a joint life policy can be cheaper than arranging two separate single-life policies, making protection more affordable for clients working within a budget. |
One claim ends the policy With a joint life first-death policy, the cover typically ceases after the first claim is paid. The surviving partner may then need to obtain new cover, potentially at an older age or with deteriorating health. |
|
Administrative simplicity One application, one policy schedule and one premium can make ongoing administration easier for both clients and advisers. |
Reduced flexibility Life circumstances change. Separation, divorce, remarriage or changing financial commitments can make a joint policy less suitable over time. |
|
Effective mortgage protection For couples whose primary concern is ensuring a mortgage is repaid on death, a joint life first-death policy can provide a straightforward solution. |
Potential ownership complications Joint ownership can sometimes create challenges when relationships break down, particularly if both parties wish to maintain protection but no longer wish to share ownership of a policy. |
The case for single life policies
Single life policies cover one individual and are increasingly viewed as a more flexible solution, despite their potentially higher overall cost.
| Advantages | Disadvantages |
|
Independent protection Each individual has their own policy, providing certainty over ownership, beneficiaries and policy decisions. |
Higher cost Two separate policies will often cost more than a single joint arrangement, which can be a significant consideration for some households. |
|
Greater long-term flexibility Single policies can continue regardless of changes in relationship status, employment circumstances or family arrangements. |
Additional administration Clients must manage multiple policies, premiums and documentation, potentially increasing complexity. |
|
Continued cover following a claim Where both individuals have separate policies, a claim on one policy does not affect the other person's cover. |
|
|
Clearer estate planning Single-life policies can often be more easily aligned with trusts and estate planning objectives, helping advisers structure protection more precisely. |
While cost and protection needs remain central, advisers should also consider broader factors.
If one partner has a significantly different health profile, separate policies may offer greater flexibility in structuring cover and managing underwriting outcomes.
The FCA’s Consumer Duty places increased emphasis on delivering good client outcomes. Advisers should consider how policy structure and ownership may affect clients if circumstances change unexpectedly.
Some clients value individual ownership of financial products. Separate policies can offer greater autonomy and control, particularly where one partner manages most household finances.
While not the primary driver in most cases, economic abuse is a relevant consideration. In relationships where financial control or coercion is present, independently owned policies may provide greater protection and resilience. Advisers do not need to investigate personal relationships, but awareness of potential vulnerabilities helps ensure recommendations remain appropriate and inclusive.
For clients seeking affordability and simplicity, particularly for mortgage protection, a joint life policy may be appropriate. For those prioritising flexibility, independence and long-term resilience, separate single-life policies may offer greater value despite a higher premium.
The adviser’s role is not simply to identify the cheapest solution, but to help clients understand the long-term implications of each option. By considering ownership, flexibility, changing circumstances and potential vulnerabilities alongside cost, advisers can support informed decisions that continue to meet clients’ needs over time.
