Mortgage insurance still concentrates the majority of its business with banks and insurers, despite a legislative framework intended to open the market. Borrowers who understand the pricing and substitution mechanisms significantly reduce the total cost of their credit. Those who settle for the group contract proposed at signing leave a sometimes considerable negotiation margin on the table.
Coverage and distribution of the remaining capital due: the underutilized lever
The insurance coverage determines the fraction of the remaining capital due covered by each co-borrower. A 100% coverage on each individual (200% in total) offers maximum protection but doubles the premium.
We observe that most borrowers accept the distribution proposed by the bank without questioning it. A 50/50 distribution seems logical for a couple with equivalent incomes, but it becomes inappropriate as soon as there is a disparity in income or professional risk between the two borrowers.
To learn everything about mortgage insurance, one must first understand that the coverage is not a fixed parameter. It is negotiable at the time of subscription and can alone justify a change of contract. Adapting the coverage to the profile of each co-borrower allows for adjusting the premium without reducing the actual coverage of the household.
A co-borrower earning the majority of the household income should logically be covered at 70 or 80%, while the other should be covered at 30 or 20%, rather than a symmetrical division that ignores the economic reality of the couple.
Structure of the borrower insurance market: why delegation remains minority
The data consolidated by the CCSF and the Banque de France indicate that in 2024, approximately 82.52% of loan insurance contracts are still offered by banks. The Lemoine law, which came into effect in 2022, allows for cancellation at any time without fees or penalties. It eliminated the medical questionnaire for loans where the insured amount does not exceed a certain threshold.
These advances have not significantly changed the actual market distribution. Banks retain a structural advantage: the group contract is presented at the time of loan signing, when the borrower wants to conclude quickly. The cognitive load associated with comparing alternative offers hinders the delegation process.
A benefit captured by the most privileged profiles
The 2024 report from the CCSF, relayed by France-Epargne, reveals a net imbalance. Upper socio-professional categories represent 58% of substitutions, while they account for only 27% of mortgage loans. The ability to compare, negotiate, and endure the administrative delay of a contract change remains correlated with the financial and cultural capital of the borrower.
We recommend that borrowers initiate comparisons as soon as they receive the loan offer, without waiting for the final signature. The bank has a legal deadline to accept or refuse the alternative contract, and this time can be utilized if the process is anticipated.
Borrower insurance guarantees: death, disability, incapacity, and exclusions
The base guarantees required by banks include death and total and irreversible loss of autonomy (PTIA). For the purchase of a primary residence, lenders almost systematically impose total permanent disability (IPT), partial permanent disability (IPP), and total temporary incapacity to work (ITT).
- The ITT guarantee covers prolonged work stoppages, but the definition of incapacity varies from contract to contract: some cover the inability to perform “one’s” profession, while others cover “any” profession, which significantly reduces the scope of compensation.
- The IPP applies when the recognized disability rate is between 33% and 66%. Some individual contracts lower the triggering threshold, a point of differentiation rarely highlighted by group contracts.
- Sporting or professional exclusions vary greatly. A borrower engaging in a high-risk sport or working in a classified dangerous profession must check the exclusions of their contract line by line before any subscription.
- The unemployment guarantee remains marginal: its high cost, long waiting periods, and restrictive triggering conditions make it unprofitable in most cases.
TAEA and the real cost of mortgage insurance: reading beyond the nominal rate
The effective annual insurance rate (TAEA) is the only standardized metric for comparing two offers. It includes all costs related to the insurance and must be included in any loan offer.
A fixed-rate contract on the initial capital maintains a constant contribution throughout the loan duration. A contract with a rate calculated on the remaining capital starts with lower contributions, which decrease over the course of repayments. The choice between these two calculation methods alters the total cost by several thousand euros on a long-term loan.
Equivalence of guarantees and bank refusal
In the case of insurance delegation, the bank can only refuse an alternative contract if the proposed guarantees are inferior to those of the group contract. It must provide a written justification for its refusal, specifying the unmet equivalence criteria.
The CCSF has published a list of equivalence criteria serving as a reference. We recommend requesting the standardized information sheet (FSI) from the bank at the first meeting: this document lists the minimum required guarantees and allows for immediate targeting of compatible alternative contracts.
Termination during the loan via the Lemoine law no longer requires any notice or anniversary date. The borrower sends the new contract to the bank, which has ten working days to accept or refuse. An unmotivated refusal within this timeframe constitutes tacit acceptance.
Mortgage insurance remains an expense category where inertia is costly. The market structure still favors banks and insurers, but comparison tools and the current legislative framework empower borrowers to take action, provided they do so before the pace of their real estate project discourages them.
