Life insurance for a mortgage
A mortgage can be one of a household's largest financial commitments. Life insurance can be arranged to help repay some or all of the mortgage if an insured person dies during the policy term.
The purpose
The question is what would happen to the mortgage if you died.
Life insurance can provide a lump sum that could be used to reduce or repay mortgage borrowing. Whether cover is needed, and how much, depends on who relies on you financially, the mortgage balance, other assets and the household's ability to continue the payments.
Someone living alone with substantial assets may have a different need from a family relying on two incomes to maintain the home.
Repayment mortgage
Decreasing cover can be designed to broadly follow a reducing mortgage balance.
With a capital-and-interest repayment mortgage, the outstanding balance should reduce over time if payments are maintained. Decreasing term assurance is commonly used for this type of borrowing because the insured amount also reduces during the term.
The policy's reduction is not guaranteed to exactly match the mortgage balance, particularly if mortgage rates, borrowing or repayment arrangements change.
Decreasing term
Cover reduces during the term and is commonly associated with repayment mortgages.
Level term
Cover stays level, potentially leaving money above the remaining mortgage balance for other household needs.
Interest-only mortgage
A reducing life policy may not match a debt that remains broadly level.
With an interest-only mortgage, regular payments generally cover interest rather than repaying the capital. The original capital normally remains to be repaid through a separate repayment strategy.
Where life cover is intended specifically to clear an interest-only mortgage, level cover may therefore be more closely aligned with a balance that is not scheduled to reduce.
Joint borrowing
A joint mortgage does not automatically mean joint life insurance is the best structure.
A joint-life, first-death policy commonly pays once following the first valid claim and then ends. Two single-life policies can potentially provide two separate amounts of cover.
A joint policy may cost less than two separate policies, but the surviving person may have no life cover left once a joint first-death claim has been paid.
The wider household
Clearing the mortgage may not solve the whole financial problem.
If the insured person also contributes towards food, utilities, childcare, education and other household spending, repaying the mortgage alone might still leave a significant income gap.
Mortgage balance
How much debt would you want repaid?
Lost income
Would the household still have enough income after the mortgage was cleared?
Dependants
How long are children or other family members likely to rely on financial support?
Existing resources
Savings, investments and employer death-in-service benefits can change the additional cover required.
Existing protection
Moving or remortgaging does not necessarily mean replacing your life insurance.
An existing policy might still meet the need, or it may need reviewing if the mortgage amount, term, household circumstances or required level of protection has changed.
Replacing an older policy can be particularly important to assess carefully because your age, health, premiums and underwriting terms may now be different.
Keep the existing policy in force until any replacement is fully underwritten and accepted, and you understand differences in exclusions, definitions, premiums, benefits and other policy terms.
Mortgage protection
Would your household be able to keep the home if an income disappeared?
We can review the mortgage alongside your income, dependants, existing benefits and protection to identify the financial risks that actually need covering.
