Whether mortgage protection is worth it depends on who relies on your mortgage being repaid and on what else would pay it. It is a decision with trade-offs rather than a rule, and this page sets out the considerations in the published words of MoneyHelper, MoneySavingExpert and an insurer. It is general information, not advice on what you should buy.

Wondering how the trade-offs look for your own loan? Use the enquiry form on this page to send a few details to an FCA-authorised broker; they can look at the mortgage and at what cover on it would involve. There is no fee, and buying is optional.

What does mortgage protection do, and what does it not do?

The name is used loosely. Here it means what most people mean by it: a life policy whose payout falls over the years, which MoneyHelper (archived August 2025) calls decreasing cover and says is designed for repayment mortgages. Which other products carry the name is set out in is life insurance the same as mortgage protection, and the mechanics in how mortgage life insurance works.

For judging its value, what it leaves out matters as much as what it pays:

  • Nothing while you are alive and ill. Life cover pays on death, not when illness or disability stops your income. Cover for illness is a different product; see mortgage protection and critical illness cover.
  • Nothing back as savings. Legal & General's Decreasing Life Insurance page (reviewed 1 June 2026) lists among its drawbacks that the policy has no cash value unless a valid claim is made.
  • Nothing after the term. The same page says "Cover will stop when the policy ends and no further premiums will be payable", and that a plan whose premiums stop being paid is cancelled with nothing returned.

On whether claims are paid at all, the Association of British Insurers' release of 29 June 2026 says 97.9% of individual protection claims were paid in 2025, a figure covering life insurance, income protection and critical illness claims together. It is not a figure for mortgage cover alone, and it says nothing about any one policy.

Who does it tend to matter for?

Value turns on who would be left with the loan. MoneyHelper's guide to life insurance (archived August 2025) links a policy's purpose to children, a partner who relies on your income and a family in a home whose mortgage you pay, and gives being single, or having a partner who earns enough for the family, as reasons you may not need one. Whether one income could carry a joint loan, and whether a lender can insist on cover, are answered in do I need life insurance for a mortgage; one joint policy against two single ones is weighed in joint or individual cover.

Someone who is the only earner, or who has children, may find the mortgage is only part of what they would want covered. A policy that tracks a repayment loan will not also fund bills or childcare, which is what family protection or mortgage protection compares.

What does MoneySavingExpert say about mortgage life insurance?

MoneySavingExpert, whose founder is Martin Lewis, answers the question in its guide to mortgage life insurance, written by its senior insurance analyst rather than by Martin Lewis himself (updated 28 July 2026; read in an archived copy of 25 September 2026). Its view, which is MSE's own, starts: "It’s not compulsory, but many people choose it when they take out a mortgage to help protect their family financially." It then says that "If you’ve got dependants (eg, children or a partner) who rely on your income, and losing it would make it hard to cover the mortgage, bills and everyday expenses, mortgage life insurance could be worth it", but asks readers first to check some exceptions:

  • No dependants. "If there's nobody to inherit your property and mortgage debt, then you don't need it – there's no point."
  • A mortgage nearly paid off. Where the debt is small enough for your dependants to cover comfortably, the guide says "it's likely not worth it".
  • Cover you already have, through work or another policy, which the next section looks at.

The guide adds a condition about the kind of mortgage, covered in the questions below. The rest of it is about how to buy, which is outside this page.

What might you already have?

Value is partly about what a new policy would add. MoneyHelper's guide to choosing protection (archived September 2025) makes checking the cover you already have one of its steps. Three places to look:

  • Cover through work. Many employers include death-in-service benefits linked to salary, and the cover ends when you leave that job. Whether such a benefit makes a new policy unnecessary is the subject of life insurance when you have death in service.
  • Savings. MoneyHelper's protection guide says "Ideally, try to save up enough money to cover three months of living expenses." How far savings would stretch against a mortgage payment is a sum only you can do.
  • A policy you already hold. MoneySavingExpert's guide says a level-term policy "might already cover the mortgage – just make sure the pay-out is enough to clear your mortgage balance and the policy lasts as long as your mortgage term." Both are in the policy's documents.

One more point from MoneyHelper: a payout could affect means-tested benefits your dependants might otherwise get.

Cover for lost income while you are alive is a separate question, weighed in income protection for a mortgage and whether income protection is worth it.

What are the pros and cons, and what does it cost?

Legal & General, which sells the product, lists what it sees as the benefits. Its guide (5 August 2026) says the cover can be tailored, with the amount chosen to match the mortgage and the term to match its length, in one name or two. Its product page says "The monthly cost is fixed so you can budget accordingly." The same page says you do not have to take out life insurance to get a mortgage, but calls doing so "a smart move". That is the insurer's own view of its own product.

The insurer's guide also names a limit: "Mortgage life insurance isn’t for everyone. For example, it might not be the right policy if you want financial protection that doesn’t lessen over time." The other drawbacks are the ones listed above: nothing paid if you outlive the term or stop paying, and no cash value. How the falling amount can drift from the loan is explained in decreasing term life insurance.

On price, MoneyHelper's guide says "The cost varies, depending on a number of factors. But life insurance is generally considered to be good value." That is a statement about life insurance generally, not about mortgage cover or any particular policy. Its protection guide lists what moves the premium, including age, "how long you’re taking it out for", and "whether you’re taking out a single or joint policy". More cover, a longer term and smoking usually raise it; adding critical illness cover does too. Nobody can honestly give a figure without your age, health and loan details.

What questions are worth weighing?

These come from the sources above and are prompts for your own thinking, not a verdict.

  • Who would be left owing, or living in, the home, and could they meet the payments on their income and what they already have?
  • MoneyHelper's protection guide asks "how would you cover your essential costs, such as mortgages or rent?" Is the answer already in place through savings or work?
  • Is the aim the loan alone, or the household's costs too? The shape of the cover follows from that; term life insurance pros and cons compares the other main type.
  • If money is tight, the protection guide says "think about your priorities or consider a lower level of cover. Some protection might still be better than none." What is the priority?
  • MoneyHelper notes "Premiums can vary, so it’s worth shopping around and comparing different quotes", and that a new policy can be cancelled for a full refund within 30 days of buying it.

If you would like these questions put to your real circumstances, put a few facts about your loan into this page's form; a broker regulated by the FCA can then explain what insurers ask about health and how a policy would be set up. Nothing obliges you to buy. For how big a policy could be, see how much life cover you need; the rest of the series is in the mortgage cover guide.

Frequently asked questions

Is mortgage protection a good investment?

No. It is insurance with no cash value, as L&G's page says, so money comes back only if a valid claim is paid during the term, and nothing grows in the meantime. Cover that lasts for life is a different product, weighed in whole of life insurance pros and cons.

Is mortgage protection worth it with an interest-only mortgage?

Not in its decreasing form, according to MoneySavingExpert's guide: "This type of policy is only suitable if you have a repayment mortgage – where you're clearing the original debt, not just the interest." On an interest-only loan the debt stays the same while decreasing cover falls. Cover that keeps one amount for the whole term is explained in level term life insurance.

As a single next step, the form lets you ask a broker authorised by the FCA to set any quote beside the cover you already hold. It takes a few minutes and is free.
