Taking out a mortgage usually means taking on the biggest financial commitment of your life. Life insurance can help protect the people who would be affected if you died, but working out the right amount is not as simple as choosing the biggest number a quote form allows.
This is an educational guide to the main ways people estimate their cover, the gaps that are often missed, and the policy details worth checking before you buy. It is not a recommendation of a particular insurer or product.
BandBack Move builds you a free week-by-week checklist tailored to exactly where you are in your move — in 60 seconds.
Build My Free Plan →A sensible starting point is to ask what would happen to the mortgage if you died. Mortgage-only cover aims to provide enough for the outstanding balance to be repaid, which could help the people you leave behind stay in the home.
That may be enough for someone with no dependants and other financial resources. It may not be enough for a family who would also lose part of their household income, need to cover childcare, or have other debts and costs to manage. The amount of cover should reflect the financial problem you want the policy to solve, not just the mortgage balance printed on the offer.
Decreasing term assurance is designed for a liability that is expected to reduce over time, such as a repayment mortgage. The potential payout generally falls during the policy term, broadly following the mortgage balance. It can be a way to focus cover on the debt, but the policy should be checked against the mortgage term, repayment type and interest assumptions.
Level term assurance keeps the potential payout at roughly the same level throughout the selected term. It may be considered where you want a fixed amount for the mortgage plus other needs, or where the debt will not reduce in the same way. It is not automatically the right choice: the useful comparison is between the cover needed, the term and the policy cost.
A repayment mortgage and an interest-only mortgage create different cover questions. Do not assume that a decreasing policy will match the balance without checking how the mortgage is actually being repaid.
There is no single calculation that works for every household. Two broad approaches are commonly used.
Income-multiple calculation. Some people begin with a multiple of the income that would be lost, then add the mortgage or other debts. This is quick and can provide a useful first estimate, but a rule such as “ten times income” cannot account for every family's spending, savings or existing cover.
Needs-based calculation. This starts with the costs the surviving household may face and subtracts resources already available. It can include:
A needs-based estimate takes more work, but it makes the assumptions visible. It can also show why two households with the same mortgage may need different amounts of cover.
Mortgage protection conversations often focus on the loan and leave out the wider financial impact. Check whether your calculation has considered credit cards, personal loans and other debts, not only the mortgage.
It is also easy to forget the value of unpaid care and household work. If one adult currently looks after children or manages the home, the surviving household may need money for childcare, domestic help or a period of adjustment even if that person has little or no salary.
Finally, allow for final expenses and check whether savings are genuinely available for this purpose. An emergency fund may already be earmarked for repairs, moving costs or everyday bills rather than being spare capital.
Many employers offer death-in-service benefits. This may reduce the amount of personal cover needed, but it should not automatically replace it. Check the benefit amount, whether it is a multiple of salary, who receives it, and what happens if you change jobs, stop working or become self-employed.
It is also worth confirming whether the benefit is discretionary and whether it is written into a trust. Treat workplace cover as part of the wider calculation, then revisit the calculation when your job, salary or family circumstances change.
If you want to discuss the gap between your mortgage, your household needs and any cover you already have, you can arrange an initial conversation with a regulated specialist. This is optional and you should compare the service and scope before proceeding.

For many mortgagors, covering only the outstanding loan is a useful starting point, not a complete answer. Consider the mortgage, other debts, dependant income replacement, final expenses, existing savings and existing cover together. Then check the policy type, premium basis, insurer comparison, term and trust arrangements.
You may decide that mortgage-only cover is enough, or that a larger level of cover better matches your household's needs. The important part is to make that decision using your own circumstances and to review it after major changes such as a new child, a job move, a new mortgage or a change in income.
For everything else that needs sorting at the same time — solicitors, surveys, EPCs and the rest — BandBack Move's free checklist keeps it all in order, built around exactly where you are in your move.
