What Mortgage Protection Insurance Covers
Mortgage protection insurance is a term covering several products: life insurance pays a lump sum on death; critical illness cover pays on diagnosis of a specified serious condition; income protection replaces a percentage of earned income if the borrower cannot work.
Life insurance for a mortgage is typically structured as decreasing term assurance, where the sum assured falls over time in line with the outstanding balance. Level term keeps the payout fixed - appropriate for interest-only mortgages where the balance does not reduce.
Critical illness cover pays on diagnosis of conditions listed in the policy, typically heart attack, stroke, certain cancers and multiple sclerosis. Policies specify exact diagnostic criteria. Some require a survival period of 14 to 30 days post-diagnosis. Policyholders should review definitions carefully before purchasing.
Is Mortgage Protection Insurance a Legal Requirement?
No UK law requires mortgage protection insurance. The FCA prohibits lenders from making mortgage approval conditional on purchasing any insurance product the lender recommends - a rule established under the Mortgage Credit Directive and MCOB rules.
Lenders do require buildings insurance as a condition of the mortgage offer, to protect the physical security for the loan. Life insurance and income protection are not legally required, though widely recommended for borrowers with dependants.
Borrowers are entitled to arrange insurance independently. The FCA's Insurance Distribution Directive requires advisers to demonstrate that any recommended product is suitable for the customer's circumstances. Independent comparison is likely to produce lower premiums than accepting the lender's offered product.
How Much Does Mortgage Protection Insurance Cost?
Premiums depend on cover type, the borrower's age, health history, occupation, sum assured and policy term. A 30-year-old non-smoker in good health might pay 8 to 15 pounds per month for decreasing term life cover on a 200,000 pound mortgage over 25 years.
Adding critical illness typically doubles or trebles the premium to 25 to 50 pounds per month for the same individual. Income protection premiums vary significantly based on the deferred period, the incapacity definition and whether the benefit increases with inflation.
A 30-year-old professional might pay 40 to 80 pounds per month for income protection covering 60 percent of gross salary with an own occupation definition and a 13-week deferred period. These are illustrative ranges - individual quotes from insurers will reflect precise circumstances.
Life Insurance vs Critical Illness Cover
Life insurance protects dependants against the financial impact of death. Critical illness protects the borrower against the disruption of a serious diagnosis. ABI statistics show critical illness claims are more frequent than life insurance claims for borrowers under 50.
Combined policies pay out on whichever trigger occurs first - death or qualifying diagnosis. Standalone critical illness pays on diagnosis and then terminates. Employers may provide death-in-service benefit that reduces the need for standalone life cover, potentially freeing budget for critical illness or income protection.
Borrowers should review total protection needs rather than addressing each product in isolation. A protection review with a whole-of-market adviser typically identifies the most cost-effective combination of cover for a specific set of circumstances and budget.
How to Buy Mortgage Protection Insurance
Mortgage protection insurance can be purchased directly from insurers, through comparison websites, or via an independent adviser or broker. Whole-of-market brokers assess needs across the full range of products rather than being restricted to one provider's range.
The FCA requires advisers recommending protection products to provide a personalised written recommendation explaining why it meets the customer's needs. Execution-only buyers are responsible for their own suitability assessment.
Premiums are typically guaranteed for the policy term if the borrower is in good health at application. Pre-existing conditions may result in exclusions, higher premiums or declined applications. Specialist insurers exist for borrowers with complex medical histories.
How to Keep Protection Insurance Under Review
Protection insurance needs change over time as the mortgage balance reduces, income changes, family circumstances evolve, and financial resilience improves. A policy taken out when the mortgage was at its highest and income was lower may be over- or under-specified several years later.
Most protection policies allow the sum assured to be reduced if the mortgage balance falls significantly below the original cover level. Reducing the sum assured lowers the premium, though the saving is often modest compared with the peace of mind from maintaining the full cover.
Remortgaging is a natural point to review protection cover comprehensively. A new fixed-rate period of two to five years represents the timeframe during which the cover will need to respond if something goes wrong. Checking whether the sum assured still matches the mortgage balance, whether the policy term aligns with the new mortgage term, and whether more competitive premiums are available from other providers all contribute to keeping protection fit for purpose.
Borrowers whose health has improved significantly since taking out the original policy - for example, those who have quit smoking or achieved a significant weight reduction - may qualify for lower premiums on a new policy, though they should confirm that a replacement policy is secured before cancelling the existing cover. Comparing multiple providers using a standardised approach - same sum assured, same term, same health assumptions - is the only way to make meaningful cost comparisons across the market. The Financial Ombudsman Service handles complaints from consumers who believe a protection insurance product was mis-sold or that a claim has been unfairly rejected. Complaints are free to bring and the FOS can award compensation and direct insurers to pay valid claims that have been declined. Borrowers who have had a claim rejected should request a final response letter from the insurer before referring the matter to the FOS, as this is a prerequisite for the service to investigate.

Frequently Asked Questions
Is mortgage protection insurance compulsory?
No. The FCA prohibits lenders from making mortgage approval conditional on purchasing protection insurance. Buildings insurance is the only cover lenders can require.
What is the difference between life insurance and mortgage protection insurance?
Mortgage protection is a broad term covering life insurance, critical illness and income protection used to protect mortgage payments. Decreasing term assurance is specifically structured to reduce alongside a repayment mortgage balance.
Can I be refused mortgage protection insurance?
Insurers can decline applications, apply exclusions for pre-existing conditions, or charge higher premiums. Specialist providers exist for applicants with medical histories that mainstream insurers decline.
Does mortgage protection cover redundancy?
Standard mortgage protection does not cover redundancy. Accident, sickness and unemployment policies cover redundancy but are separate products with different terms and typically limit payments to 12 to 24 months.
How long should the policy term be?
At minimum the term should match the mortgage term. Some borrowers choose a longer term if they have dependants who would need support beyond the mortgage payoff date.
