Life insurance for a mortgage

UK lenders do not legally require you to have life insurance to take out a mortgage, but most strongly recommend it. The aim is simple: if you die during the mortgage term, the policy can pay off some or all of the loan so the home is not at risk for whoever is left.

This guide covers when life insurance fits a mortgage, the type of cover that usually suits, and the common mistakes to avoid.

Is life insurance compulsory for a mortgage?

No. There is no UK law that says you must have life insurance to borrow money for a home. The Financial Conduct Authority’s mortgage rules do not require it.

That said:

• Most lenders highlight the importance of life cover at application.
• A broker will normally discuss it as part of the protection conversation.
• Some lenders will signpost or recommend cover, but they cannot make a mortgage offer conditional on you buying a specific policy.

The decision is yours, but for most homeowners with a partner or dependants, going without cover means a serious financial gap if the worst happens.

What does mortgage life insurance cover?

Mortgage cover is a term used loosely. In practice, it is a life insurance policy designed to pay a lump sum if you die during the term, with the cover sized to clear the mortgage.

The policy is not tied to the mortgage account. It is a personal policy, and the payout goes to your estate or, if written in trust, to chosen beneficiaries. They can then choose to clear the mortgage with the proceeds.

Two main types are used:

• Decreasing term cover, which falls broadly in line with a repayment mortgage balance.
• Level term cover, which keeps the sum assured flat throughout the term.

Repayment mortgage: decreasing term cover

If you have a repayment mortgage, you pay down the capital and interest each month. MoneyHelper notes that the balance falls over time as more of each payment goes towards capital.

Decreasing term life insurance is designed to follow a similar curve, although it uses an assumed interest rate. If your mortgage rate stays close to the assumed rate, the cover roughly tracks the loan.

This is usually the cheapest type of cover for a given starting amount, because the insurer is on the hook for less money over time.

Interest-only mortgage: level term cover

If you have an interest-only mortgage, the capital does not reduce during the term. Each month you pay interest only, with a separate plan, savings, or a sale to clear the capital at the end.

Level term cover keeps the sum assured flat for the whole term, which matches the shape of an interest-only loan. If the loan does not fall, the cover should not fall either.

Joint or single life policies?

For couples with a joint mortgage, there are two common options.

• A joint life first death policy. This pays once, on the first death during the term.
• Two single life policies. These pay if either person dies during the term, and can pay twice if both events happen during the term.

Two single life policies are often only modestly more expensive than a joint life policy. They also continue separately if the relationship changes, which a joint policy does not.

How much cover do you need?

The simple test is whether the payout would be enough to clear the loan and ideally support the household afterwards.

A practical approach:

• Cover at least the outstanding balance of the mortgage.
• Match the term to the mortgage term, or slightly longer if you may extend.
• Consider extra life insurance on top to support living costs and dependants beyond just clearing the loan.

If only the mortgage is cleared, a surviving partner still needs to pay the bills, support children, and replace any lost income. Many homeowners buy two layers of cover: decreasing term to track the mortgage, and level term for family protection.

Should you write the policy in trust?

For most family protection policies, putting cover into trust can help the payout reach beneficiaries more quickly and may keep it outside the estate for Inheritance Tax purposes, depending on the wider position.

GoInsureMe has a separate guide on life insurance in trust that covers this in more detail. The right choice depends on your circumstances, and for complex estates, professional legal or tax advice may be sensible.

What about critical illness or income protection?

Life insurance only pays on death or, depending on the policy, terminal illness. It does not help if you survive a serious illness or are unable to work.

For a mortgage, two other policies often play a part:

• Critical illness cover can pay a tax-free lump sum if you are diagnosed with one of the conditions listed in the policy and the diagnosis meets the policy definition.
• Income protection can pay a regular monthly amount if illness or injury stops you working.

Many homeowners use a combination: life cover for the worst case, critical illness cover for big one-off costs, and income protection to cover months of inability to work.

Watch out: common pitfalls

A few common mistakes.

• Term too short. A 20-year cover term will not match a 25-year mortgage. If you remortgage and extend, your cover may end before the new mortgage does.
• Cover too small. The mortgage balance is the floor, not the ceiling. Many households also need cover for living costs and dependants.
• Only one partner insured. If a household relies on two incomes, both people usually need cover.
• Joint policy assumed to pay twice. A joint life first death policy pays once. Two single life policies can pay twice.
• No trust set up. Without a trust, the payout may be paid into the estate, which can be slower and may interact with Inheritance Tax depending on the size of the estate.
• Non-disclosure. Underwriting questions must be answered fully and accurately. The insurer may decline a claim if non-disclosure is later found.

How does this connect to claims?

Protection insurance is designed to pay valid claims that meet the policy terms. The Association of British Insurers reported that UK protection insurers paid a record GBP 8 billion in combined group and individual protection claims during 2024.

For mortgage protection, the practical question is whether the payout reaches the right people fast enough to keep the home secure. The right product, term, sum assured, and trust setup all play a part in that.

Bottom line

Life insurance is not legally required for a UK mortgage, but for most households with a partner or dependants it is one of the most useful pieces of protection. Decreasing term cover often suits a repayment mortgage, level term cover suits interest-only, and combining life cover with critical illness or income protection helps cover illness as well as death.
