It is the cheapest line of your whole budget and the one that holds up the keys. A policy costs about four euros a month, the certificate arrives in five minutes, and you can take it out from abroad before you land.
Renting a home you live in means insuring it. The lease you sign says so, and the landlord may ask you for the certificate again each year. It covers what you would otherwise owe out of your own pocket: a fire, water running into the flat below, a broken window.
On HelloFonty it is also what opens the door, literally: the access guide of your home, with its entry codes and its instructions, stays closed until your certificate is uploaded and checked. Nobody is trying to be difficult, it is simply the one paper the landlord cannot do without.
Before you arrive, not after. A policy can start on a date you choose, so take it out once your booking is accepted and set it to begin the day your lease does. You will then have the certificate in hand on the day you ask for the keys instead of hunting for one from a hotel room.
You do not need a French bank account for most of these: a foreign card is enough. That is the question we are asked most often, and the answer is no.
Three things, and they are the three reasons a certificate gets refused: your own name, the exact address of the home, and a period that actually covers your lease. A policy in a flatmate’s name, or one that starts a month after you move in, will come back to you.
In a flatshare, each tenant insures themselves unless the policy explicitly names everyone. Check that line before you pay.
Five ordinary public offers, in order of entry price. Every one of them issues the certificate straight away, which is what matters here.
HelloFonty is tied to none of these insurers and earns nothing if you take one out. They are listed because they are cheap and quick, and for no other reason. Prices checked on 22 September 2026, and a price can move.
