"What is borrower insurance delegation?"

"Delegation consists in choosing an external insurer rather than the group contract offered by the bank. It has been authorised since the 2010 Lagarde law."

"Can you change borrower insurance at any time?"

"Yes, since the 2022 Lemoine law, borrower insurance can be changed at any time and free of charge, with equivalent guarantees."

"How much can you save by changing borrower insurance?"

"Up to 30 to 50 percent of the total insurance cost, i.e. several thousand euros over a 20-year loan."

Borrower insurance: delegation or group contract?

In short

Delegation possible from the loan subscription (Lagarde law)
Change possible at any time after signing (2022 Lemoine law)
Average saving: 30 to 50 percent on the total cost
Condition: guarantees at least equivalent to the group contract

Borrower insurance represents up to 30 percent of the total cost of a mortgage. Choosing delegation rather than the bank’s group contract allows significant savings.

Group contract vs delegation

Criterion	Group contract (bank)	Delegation
Pricing	Mutualised across the group	Personalised to profile
Age, health, profession	Little considered	Finely considered
Guarantees	Standardised	Adjustable
Cost	Generally higher	Generally lower

Who benefits most from delegation?

The profiles that benefit most:

Non-smokers
Young professionals (under 40)
Professions without particular risk
Borrowers in good health

For a 30-year-old borrower on a 200,000 euros loan over 20 years, the difference between group contract and delegation can reach 10,000 to 15,000 euros over the total life of the loan.

The Lemoine law changed the game

Since 2022, the Lemoine law allows:

Borrower insurance change at any time
Elimination of the medical questionnaire for loans under 200,000 euros repaid before 60
Right to be forgotten reduced to 5 years for cancer and hepatitis C

How to change borrower insurance?

Compare offers (broker or online comparator)
Subscribe to the new contract with equivalent guarantees
Send a substitution request to the bank (registered letter)
The bank has 10 days to respond
In case of unreasoned refusal: referral to the DGCCRF

The key criterion is the equivalence of guarantees. The bank can only refuse on this basis. The required guarantees appear in the standardised information sheet provided at signing.

The Lemoine law opened up the borrower insurance market. All borrowers should compare at least once after signing the loan, and switch if savings exceed 1,000 euros over the remaining term.
