Mortgage Protection Insurance
Taking out a mortgage means taking on a significant, long-term financial commitment — and mortgage protection insurance exists to make sure that commitment does not fall on your family if you die during the term. Our mortgage protection insurance calculator estimates your likely monthly premium based on your age, the mortgage amount, the term, and your health.

Decreasing Term vs Level Term: The Key Choice
Decreasing term life insurance is specifically designed to mirror a repayment mortgage — the cover amount reduces over time roughly in line with your falling mortgage balance, and because the insurer’s risk decreases each year, decreasing term cover is typically significantly cheaper than level term cover for the same starting sum assured. Level term insurance keeps the payout amount fixed for the whole policy term, which costs more but provides a bigger cushion — useful if you want the payout to also cover other needs, such as replacing income or leaving a larger legacy, rather than purely clearing the mortgage.
What Actually Drives Your Premium
Age is the single biggest factor — premiums rise steeply as you get older, because mortality risk increases with age. Smoking status typically more than doubles the cost, since insurers price smokers separately using different mortality tables. The length of the term matters too: a 30-year policy costs more than a 15-year one for the same cover amount, both because you are older on average across the policy and because there is simply more time for a claim to occur. Health conditions can add further loading, or in some cases require specialist underwriting.
Do You Actually Need Mortgage Protection?
If you have dependants relying on your income, or a partner who could not afford the mortgage alone, mortgage protection insurance is generally sensible — without it, a death during the mortgage term could force a sale of the family home at an already difficult time. Single applicants with no dependants and no joint mortgage may reasonably decide the cover is less critical, though many still take a smaller policy for peace of mind or to protect a joint applicant’s interests.
A Worked Example
A 35-year-old non-smoker taking decreasing term cover for a £220,000 mortgage over 25 years might expect a monthly premium in the region of £12–£16, compared with roughly £22–£28 for equivalent level term cover — illustrating the meaningful saving decreasing term offers when the sole purpose is protecting a specific, reducing mortgage balance. A smoker of the same age would typically see this more than double.
Combining Cover with Critical Illness Protection
Many people choose to add critical illness cover alongside their mortgage life insurance, which pays out a lump sum if you are diagnosed with a specified serious illness — such as certain cancers, a heart attack or a stroke — while you are still alive, rather than only on death. Given that serious illness is statistically more likely to disrupt your ability to pay a mortgage during your working life than death itself, this combination is worth at least considering, even though it increases the overall premium. Some insurers offer combined life and critical illness policies at a modest discount compared with buying each separately, so it is worth requesting both quotes side by side when comparing options rather than assuming standalone life cover alone is sufficient protection.
Frequently Asked Questions
Is mortgage protection insurance a legal requirement?
No — it is not a legal requirement in the UK, though some lenders may ask about your protection arrangements, and it is widely recommended as sound financial planning for anyone with dependants or a joint mortgage.
What is the difference between this and buildings insurance?
Buildings insurance (which most lenders do require) covers physical damage to the property itself. Mortgage protection life insurance is a completely separate product that pays out to clear or reduce the mortgage if you die during the policy term.
Can I get cover if I have a pre-existing health condition?
Often yes, though it may come with a higher premium or specific exclusions, depending on the condition. Some specialist insurers focus specifically on higher-risk applicants who mainstream insurers decline or heavily load.
Should I choose joint life or two single policies?
A joint life policy typically costs less than two single policies but only pays out once — on the first death. Two single policies cost more combined but mean each partner has independent cover, which some couples prefer for full protection of both lives.
