Is mortgage protection insurance a different product from ordinary life insurance?

No — mortgage protection insurance is not a separate category of product; it is decreasing term life assurance sold with marketing aimed specifically at a mortgage. Its pay-out schedule is shaped to fall roughly in line with a repayment mortgage balance, and it does exactly one job: clearing that debt if you die. Because it is simply a term policy sized and shaped to a debt, it can be bought from any insurer offering decreasing term cover, not only from whoever arranged the mortgage.

Why might decreasing cover be the wrong choice for an interest-only mortgage?

Decreasing term cover is designed around a balance that falls each year, which matches a repayment mortgage as monthly payments reduce what is owed. An interest-only mortgage does not work that way: the balance stays the same throughout, since only interest is paid monthly and the capital is repaid separately at the end. Matching shrinking cover to a balance that never shrinks leaves a growing gap as the years pass, so level term cover, which pays a fixed sum throughout, is the more appropriate structure for an interest-only loan.

Am I required to buy mortgage protection insurance from my mortgage lender?

No. Lenders commonly offer their own protection insurance at the point of sale, and it can be convenient to arrange everything together, but you are under no obligation to buy it from them. Any insurer authorised to sell life insurance can provide decreasing or level term cover against the same mortgage, and the FCA’s conduct rules apply equally to whichever firm you choose. Comparing a written quote from the lender against quotes from other insurers, on an identical specification, is the only way to know whether the lender’s offer is competitive.

Life insurance vs mortgage protection insurance: what’s the difference?

The short answer

“Mortgage protection” is usually decreasing term life insurance sized to your mortgage: the pay-out falls with the balance and clears the debt if you die. Standard level term cover costs more but can clear the mortgage and leave money over. The right structure depends on everything the money needs to do, not just the loan.

Thinking about the difference between life insurance and mortgage protection

What works well

Decreasing cover matches the debt cheaply and precisely.
Level cover protects the mortgage and everything after it.
You can buy from any insurer — never only from the lender.

What to watch

Interest-only mortgages need level, not decreasing, cover.
The policy’s decrease rate may not track your mortgage rate.
A debt-only policy leaves family income unprotected.

Cover shaped to the debt, or shaped to the family

Mortgage protection insurance is not a separate species of product: it is decreasing term life assurance marketed against a specific debt. Its pay-out schedule falls roughly in line with a repayment mortgage, it costs less than level cover of the same starting figure, and it does exactly one job. The questions that expose the difference are practical. Is your mortgage repayment or interest-only? Interest-only balances do not shrink, so decreasing cover mismatches them. Would your family need money beyond the mortgage — income, childcare, other debts? Decreasing cover leaves nothing for those. And does the policy’s assumed decrease rate track your actual mortgage rate? A gap opens if rates diverge. Lenders may offer their own cover at sale, but you are not obliged to buy it from them, and the FCA’s conduct rules apply to whoever sells it.

Price both structures on an identical starting sum before deciding — the premium difference between decreasing and level cover is often smaller than expected, and the level policy’s surplus buys flexibility. Whatever the specifics of the difference between life insurance and mortgage protection, the discipline that protects your family is always the same: get the insurer’s position in writing, keep the documents with the policy, and make sure the people who would claim know the policy exists and where the paperwork lives.
