6 Reasons why you should buy whole life insurance

Updated: 5 Oct 2026

Quick answer

Whole life insurance, also known as whole of life insurance or life assurance, provides cover for the rest of your life. It pays a lump sum when you die, provided you keep up with the premiums and the claim meets the policy terms.

It may suit someone who wants to leave an inheritance, help with funeral costs, cover a permanent financial need or provide funds towards a potential Inheritance Tax bill.

It's usually more expensive than term life insurance, and you could pay more in premiums than the policy eventually pays out.

How whole life differs from term insurance

The main difference is how long the cover lasts.

Our guide to whole life insurance vs term life insurance explains the differences in more detail.

Important payout conditions

Whole life insurance does not expire after a set number of years, but this does not mean every claim is automatically accepted.

A claim will normally depend on:

• The policy still being active when the insured person dies

• The required premiums having been paid

• The information supplied during the application being accurate and complete

• The claim meeting the policy terms and not falling within an exclusion

Life insurance may cover death caused by illness, an accident or natural causes, but the exact terms vary. Some policies also exclude suicide during an initial period of cover.

Answer every application question honestly and accurately. If important health or lifestyle information was misrepresented, the insurer may reduce the payout, cancel the policy or refuse the claim.

Read the policy documents carefully and see our guide to getting life insurance with a pre-existing medical condition for more information.

Six reasons to consider whole life insurance

1. You want cover that lasts for life

Unlike term insurance, whole life insurance has no set expiry date. It can pay out whether you die a few years after taking it out or several decades later, provided the cover remains active and the claim is valid.

That certainty may appeal if you have a permanent financial need, although whole life cover is generally more expensive than term insurance.

2. You want to leave an inheritance

A whole life policy can provide a lump sum for your chosen beneficiaries. They could use the money for living costs, education, housing or another purpose that matters to them.

A level payout stays the same, so inflation can reduce its spending power over time. Some policies offer increasing cover, where both the sum assured and premiums normally rise.

3. You want to help with funeral costs

Funeral costs can leave families with an immediate bill at an already difficult time. A whole life payout could help meet some or all of these costs, provided the amount of cover is sufficient.

Check how the benefit will reach the intended recipient, as probate may affect how quickly money from the estate becomes available.

4. You have a long-term debt or financial liability

Whole life cover may help where a liability does not have a clear end date. For example, it could provide money towards an equity release balance or another obligation that may still exist when you die.

It is not always the most cost-effective choice for a standard repayment mortgage or another debt that reduces over a set period. Decreasing or level term insurance may be more closely matched to these needs.

Debts held solely in your name are normally repaid from your estate, while joint debts will usually remain the responsibility of the surviving borrower. Our guide explains more about using life insurance to help pay off debt.

5. You want to help meet a potential Inheritance Tax bill

Whole life insurance is sometimes used to provide funds towards an expected Inheritance Tax liability.

The standard Inheritance Tax rate is currently 40%, but it normally applies only to the part of an estate above the available tax-free thresholds. The basic nil-rate band is £325,000. Spouse or civil partner exemptions, the residence nil-rate band and transferred allowances may change how much tax is due.^[1]

If the policy payout forms part of your estate, it could increase the estate’s value for Inheritance Tax purposes. Placing a suitable policy in trust may keep the payout outside the estate and allow it to be paid without waiting for probate.

Trusts can have lasting legal and tax consequences. Cavendish Online cannot provide tax advice, so speak to a solicitor or suitably qualified tax adviser before making a decision. You can also learn more about writing a life insurance policy in trust.

6. You want the option of predictable premiums

Some whole life policies offer guaranteed premiums. These stay at the agreed amount, even as you get older or your health changes after the cover begins.

Other policies have reviewable premiums, which the insurer can reassess at set points. They may increase and could become difficult to afford later.

Check whether the premiums are guaranteed, reviewable or linked to increasing cover. A fixed premium can make long-term budgeting easier, but it does not make the policy good value for everyone.

Cost considerations

There is no standard price for whole life insurance. The premium usually depends on:

• Your age

• Your health and medical history

• Whether you smoke or use nicotine products

• Your occupation and any hazardous hobbies

• The amount of cover

• The policy and premium structure

Monthly premiums are often lower when cover is taken out at a younger age, but you may pay them for longer. It is therefore important to consider the potential lifetime cost rather than looking only at the initial monthly premium.

Choose an amount of cover that reflects the financial need you want to meet and consider term insurance where that need only lasts for a set period.

If you already have life insurance, do not cancel it until any replacement policy is active. Changes to your age or health could mean that new cover costs more or is offered on different terms.

Drawbacks to consider

Whole life insurance can offer greater certainty, but there are several disadvantages to consider:

• Premiums are usually higher than for term life insurance.

• You may pay more into the policy than it eventually pays out.

• Cover can end if you stop paying the premiums.

• Reviewable premiums may rise.

• A level payout can lose value as prices increase.

• Standard whole life policies offered by Cavendish Online have no cash-in value.

• Term life insurance may provide more cover for the same monthly budget when the financial need is temporary.

When whole life insurance may be suitable

Whole life cover may be worth considering if you have a permanent need for a payout and can afford the premiums over the long term.

Before applying, ask:

• What would the payout need to cover?

• Does that financial need last for life or only for a set period?

• Can I afford the premiums if my income or circumstances change?

• Would single or joint cover be more suitable?

If your main aim is to cover a repayment mortgage, replace income while children are dependent on you or protect another temporary commitment, term life insurance may offer a better fit at a lower cost.
