Is life insurance compulsory with a mortgage?

No. In the UK, a mortgage lender cannot insist you take out life insurance as a condition of the loan. Some lenders may ask whether you have cover, and a broker might recommend it, but the decision is yours. That said, "not compulsory" is not the same as "not needed". If anyone relies on your income to pay the mortgage, or if you own a home jointly and the surviving owner could not manage the payments alone, life cover is worth serious thought. If you are single with no dependants and enough savings to cover the mortgage, you might reasonably decide to skip it.

Repayment mortgages and decreasing term cover

Most UK mortgages are repayment mortgages. Your balance falls gradually at first and faster later, as more of each payment goes towards capital. A decreasing term life insurance policy is designed to mirror that pattern. The payout reduces over time, roughly in line with a repayment mortgage, and the premiums are usually lower than level term cover for the same starting amount. For example, if you have a £200,000 repayment mortgage over 25 years, a decreasing term policy set to run for 25 years could clear the remaining balance if you die during the term. It is not a perfect match, especially if you overpay, make lump-sum reductions or switch to a different mortgage deal. Overpaying can leave the policy paying more than the outstanding debt near the end, which is not a problem for your family, but it does mean you may have paid for cover you no longer strictly needed.

When level term makes more sense

Level term life insurance pays a fixed sum whenever you die during the policy term. It is often the better fit if you have an interest-only mortgage, because the capital does not reduce. It can also suit repayment borrowers who want the payout to cover more than the mortgage: childcare costs, school fees, credit cards, funeral expenses or a few years of lost income. Level cover costs more than decreasing term for the same initial sum, because the payout does not shrink. If you want a fixed lump sum that your family can use flexibly, rather than a figure that tracks the mortgage balance, level term is the straightforward choice. Family income benefit is another option: it pays a regular tax-free income for the remaining policy term instead of one lump sum, which can help with ongoing household bills.

Joint policies, trusts and payout practicalities

Joint life first death policies cover two people and pay out when the first dies. They are usually cheaper than two separate policies, but they only pay once. If the surviving partner later dies, there is no second payout unless they take out new cover. For some couples, two single policies offer better value and certainty, particularly if both incomes are needed to pay the mortgage. Putting a policy in trust is often sensible. It can speed up payment, because the money does not have to wait for probate, and it may keep the payout outside your estate for inheritance tax purposes. You can usually set up a trust when you apply, at no extra cost. Make sure the policy term matches the mortgage term, and tell your partner or trusted person where the policy details are kept. Do not assume the lender will automatically use the payout to clear the mortgage; the money goes to your nominated beneficiaries or trustees, and they decide how to use it.

How much cover do you actually need?

Start with the outstanding mortgage balance and the years left on the loan. A simple way to work out the gap is:

• Add up the mortgage, other debts and funeral costs.
• Add the income your household would lose, especially if children depend on it.
• Subtract savings, investments and any death-in-service cover from your employer.
• Check the remaining figure against the cover you already have.

Many workplaces offer a lump sum, often a multiple of salary, but it may not be enough and it usually ends when you leave the job. If you have children, think about childcare and everyday living costs, not just the mortgage. If you are the lower earner, your income may still be essential for bills. Review your cover when you move home, remortgage, have a child or take on significant new debt. If your health has changed since you took out an older policy, think carefully before cancelling it, as a new policy may cost more or be declined.

Alternatives and common pitfalls

Life insurance is not the only protection. Critical illness cover pays a lump sum if you are diagnosed with a specified condition, and income protection pays a monthly income if you cannot work through illness or injury. These can be more expensive and are not a substitute for life cover, but they address different risks. Mortgage payment protection insurance, which covers accident, sickness and unemployment, is often poor value compared with standalone income protection. Common pitfalls include buying decreasing term cover for an interest-only mortgage, choosing a joint policy when two singles would be better, forgetting to review cover after a remortgage, and assuming your lender requires insurance. A regulated adviser can help you compare options, but you can also research directly. The right answer depends on your mortgage type, your family situation and what you could afford if the worst happened.
