Whole of Life Insurance: Guaranteed Cover That Never Expires

Whole of life insurance is a type of life insurance policy that stays in force for your entire life rather than expiring after a fixed term. As long as you keep paying the premiums, your policy is guaranteed to pay out a tax-free lump sum to your beneficiaries whenever you die, whether that's next year or in 40 years' time.

This makes whole of life cover fundamentally different from term life insurance, which only pays out if you die within a set period, such as 20 or 25 years. Because whole of life insurance guarantees a payout, insurers price it higher than equivalent term cover, and most policies require a straightforward medical underwriting process rather than the simplified acceptance used by over 50s life insurance, which skips health questions but caps cover and can cost more per pound of cover.

• No expiry date: Cover runs until you die, however old you are when that happens.
• Guaranteed payout: Provided premiums are paid and you disclosed health information honestly at application, a claim will be paid.
• Level or increasing cover: Most policies fix the payout amount at outset, though some let you build in inflation increases.
• Full medical underwriting: Unlike over 50s plans, you'll typically answer health questions and may need a GP report for higher cover amounts.

Taking out whole of life insurance follows four steps: you apply and answer health and lifestyle questions, the insurer underwrites your application (sometimes asking for a GP report or arranging a phone medical), you pay a monthly or annual premium for the rest of your life, and your beneficiaries receive the guaranteed sum assured when you die. There's no renewal, no reapplication, and no risk of the policy running out while you're still paying into it.

Where whole of life policies differ most is in how the premium is structured, and this decision affects what you pay for decades. A guaranteed premium policy fixes your monthly cost at outset, so a policy that costs £45 a month at age 45 still costs £45 a month at age 75. A reviewable premium policy starts cheaper, often 20 to 30 percent less, but the insurer reviews pricing every five or ten years and can increase it sharply if claims experience or investment returns have been worse than assumed. Reviewable premiums have been known to double at a single review.

When your policy eventually pays out, the process for how a life insurance claim is paid out typically takes 10 to 15 working days once the insurer receives a death certificate and completed claim form, assuming there's no dispute over non-disclosure.

Not all whole of life policies work the same way. Insurers offer several structures, and picking the wrong one can mean paying more than necessary or ending up with a policy that doesn't match your goal.

The most common is a standard guaranteed policy, which fixes your premium and sum assured for life and suits people who want certainty above all else. Unit-linked and with-profits versions invest part of your premium, so the payout, and sometimes the premium, can fluctuate with investment performance, which suits people comfortable with some risk in exchange for potential growth. Low-cost or decreasing policies reduce the guaranteed sum assured over time, often used to offset an anticipated inheritance tax liability that shrinks as you age. Flexible policies let you adjust cover up or down as circumstances change, and reviewable policies, covered above, trade a lower starting premium for future price risk. Most UK insurers only offer two or three of these structures, so it's worth checking which type you're actually being quoted before you compare prices, since a cheaper reviewable quote isn't directly comparable to a guaranteed one.

Whole of life insurance for a healthy non-smoker typically costs between £13 and £270 a month, depending heavily on your age at application and how much cover you choose. Because whole of life guarantees a payout eventually, premiums run significantly higher than average life insurance costs for equivalent term policies, where a 30-year term policy for £100,000 of cover might cost a healthy 30-year-old under £10 a month.

Five factors drive your premium: your age at the start of the policy (the single biggest factor, since underwriters price in your statistical remaining lifespan), your health and any pre-existing conditions, whether you smoke (smokers often pay 50 to 100 percent more), the amount of cover you choose, and whether you pick guaranteed or reviewable premiums.

• Age: A 65-year-old will pay several times more than a 35-year-old for the same £50,000 of cover.
• Health: Conditions like diabetes or heart disease can add loadings of 25 to 100 percent or more.
• Smoker status: Smokers are underwritten separately and typically pay considerably more than non-smokers of the same age.
• Cover amount: Doubling your sum assured roughly doubles your premium at a given age.

Choosing between whole of life and term life insurance comes down to what you're protecting against. Term life insurance covers you for a fixed period, commonly 10 to 35 years, and only pays out if you die within that window; if you outlive the term, the policy simply ends and you get nothing back. Whole of life insurance costs more for the same sum assured because the insurer knows a claim is a certainty eventually, not a possibility.

For most people protecting a mortgage or replacing income while children are dependent, term life insurance is cheaper and better matched to the need, since the risk (an outstanding mortgage or a child's dependency) also reduces over time. Whole of life insurance suits goals that don't have a natural end date, such as covering funeral costs whenever they arise, leaving a guaranteed inheritance, or covering an inheritance tax bill that will exist for as long as your estate does.

Inheritance tax becomes relevant to whole of life insurance because a payout on death counts as part of your estate for tax purposes unless you've taken action to exclude it. The standard nil-rate band is £325,000 per person, with an additional £175,000 residence nil-rate band available in many cases when a main home passes to direct descendants. Estates above these thresholds are taxed at 40 percent on the excess, so a life insurance payout landing in your estate can push your beneficiaries into a tax bill they weren't expecting, sometimes on money that was meant to help pay inheritance tax in the first place.

The fix is writing your policy in trust at the outset. Putting a whole of life policy in trust means the payout goes directly to your named beneficiaries and sits outside your estate for inheritance tax purposes, so it isn't counted when HMRC calculates what's owed. It also means the money can be paid out faster, since it bypasses the probate process, which can otherwise take months. Setting up a trust is usually free and takes a single form at application, but many policyholders miss this step entirely, which is one of the most common and costly mistakes in whole of life planning.

Whole of life insurance has clear strengths and clear trade-offs, and weighing them honestly helps you decide if it's the right fit.

• Guaranteed payout: As long as premiums are paid, a claim will be paid, whenever you die.
• No expiry worry: You'll never outlive the cover and be left with nothing, unlike term insurance.
• Useful for fixed costs: Ideal for funeral expenses, often £4,000 to £5,000 in the UK, or a known inheritance tax liability.
• Can build cash value: Some with-profits and unit-linked versions accumulate a surrender value over time.

• Higher cost: Premiums run several times higher than equivalent term cover for the same sum assured.
• Reviewable premiums can rise sharply: A cheaper starting price can mean an unpleasant increase at the five or ten-year review point.
• Poor value if cancelled early: Cashing in during the early years often returns far less than you've paid in.
• Full underwriting required: Unlike over 50s cover, you may be declined or heavily loaded for serious pre-existing conditions.

Whole of life insurance tends to make sense if you want to guarantee an inheritance regardless of when you die, you're planning specifically around an inheritance tax bill, you want to cover funeral and estate administration costs without leaving family to find the money, or you've already got term cover for your mortgage and income needs and want something permanent on top. If you're mainly protecting a mortgage, replacing lost income while children are dependent, or looking for the cheapest possible cover, working out whether you need life insurance at all and comparing against term cover first will usually save you money.

If whole of life is right for you, get the most from your quote by comparing several providers rather than accepting the first offer, since premiums for identical cover can vary by 30 percent or more between insurers. Disclose your health and lifestyle accurately, since undisclosed conditions are the most common reason claims are refused. Decide upfront whether guaranteed or reviewable premiums suit your budget for the next 20 to 30 years, and set up your trust at application rather than leaving it until later, since it costs nothing to do at outset.
