French insurance: what's compulsory, what's not, and how to switch

The lie of the land

Before any of the detail, it helps to see the shape of French insurance as a whole, because most of what surprises Britons is structural rather than complicated. Four things are worth holding in your head from the start.

First, more of it is compulsory than you're used to. Renting, or owning a flat in a block? Home insurance is a legal requirement, not just a sensible precaution. Car insurance is compulsory for everyone, as at home. Only the detached-house owner has genuine discretion — and even there, French liability law makes cover the obvious choice. Running underneath all of it is a single practical truth: the certificate is what people actually ask for. No attestation d'assurance, no keys at the état des lieux.

Second, the way it's sold is not quite neutral. The comparison sites everyone reaches for — the comparateurs — look like impartial referees but are paid by the insurers they list, and show only their partners. Useful, but not the whole market. Knowing that changes how you use them.

Third, one policy quietly does several jobs. The standard French home policy, multirisque habitation, bundles fire, water, theft and the personal liability cover (responsabilité civile) that schools and clubs keep asking for — so a lot of people end up paying twice for cover they already hold.

And fourth, switching is easy — once you know two laws exist. This is the one with a bit of history behind it, so it's where we'll start. The rest of the landscape follows underneath.

Switching: the exit used to be the trap

Let's clear up a myth first, because it's the wrong thing to worry about. Insurance auto-renews in Britain too — that's precisely why the FCA had to ban "loyalty penalty" pricing, where insurers quietly charged long-standing customers more each year. Automatic renewal (in France, tacite reconduction) is not some peculiarly French trap. If you've ever let a UK renewal letter roll over rather than shopping around, you already know the feeling.

What genuinely used to be different in France was how much harder it was to leave. For decades, cancelling meant catching a narrow window of a week or two around your anniversary date and sending a formal registered letter (lettre recommandée) in French to do it. Miss the window — as newcomers routinely did — and you were locked in for another full year, watching the premium creep up while a better deal sat one click away. The sting was never the renewal; it was the bureaucratic exit ritual.

Two laws have quietly dismantled that ritual, and once you know they exist, switching French insurance becomes genuinely painless. The catch is that nothing on your renewal letter will spell them out for you.

The Loi Hamon: cancel any time after year one

The Loi Hamon (the consumer law of 17 March 2014, in force from 1 January 2015) is the one that changed everything. Once your home or car policy has run for its first twelve months, you can cancel it at any time, for any reason, with no penalty and no fee. No waiting for the anniversary. No begging letter explaining yourself. You simply decide you've had enough.

Better still, you usually don't lift a finger. When you take out the new policy, you tick a box — the mandat de résiliation — and your new insurer cancels the old one for you, timing it so there's no gap in cover. That last point matters enormously for car insurance, where a lapse in cover is a criminal offence, not a paperwork slip. The whole handover is designed so you're never uninsured for a single day.

The Loi Chatel: the backstop if they play games

The Loi Chatel is the older law (2005) that handles the first twelve months, before Hamon kicks in — and it's also your safety net if an insurer plays games. It obliges your insurer to remind you, in writing, that a cancellation deadline is coming, at least fifteen days before that deadline. The reminder arrives with your renewal notice (the avis d'échéance).

Here's the useful part. If the insurer sends that reminder on time, you have twenty days from the notice to cancel for the coming renewal. If they send it late, or never send it at all — which happens more often than you'd think — the rules flip in your favour: you can cancel at any time after renewal, and you're owed a refund of the premium paid since. So if you've missed a window and an insurer is being difficult, the first question is always: did they actually send me the Chatel reminder, and when? Check the postmark. It's frequently your way out.

The comparison sites aren't the neutral referee they look like

Sooner or later everyone reaches for a comparateur — LeLynx, Assurland, LesFurets, Hyperassur. They're fast, they're free to you, and they feel like an impartial scan of the whole market. They are not. It's worth understanding exactly what they are before you trust the ranking.

A comparateur is paid by the insurers it lists. When you take out a policy through the site, the insurer pays it a commission — that's the entire business model, and it's why the service is free to you. The consequence is simple: only insurers who've signed a commercial deal with the comparateur appear in the results. Big, competitive names — several of the mutuelles, the bancassureurs, and plenty of direct insurers — are often missing entirely, because they don't pay to play. You're not comparing the French market; you're comparing the comparateur's partner list.

There's a British in-joke buried here, too. LeLynx.fr is the French sibling of Confused.com — same parent group — so the mascot-with-a-French-cap you're squinting at is a UK price-comparison brand in a beret. None of which makes comparateurs useless. As a first pass to get a feel for the going rate, they're genuinely handy. Just don't treat the top result as the best deal in France. Cross-check two or three comparateurs against each other, then approach the big names they leave out — a mutuelle like the MAIF or the Macif, or a bancassureur through your own bank — directly. The graphic below shows where your money and your data actually go on each route.

What's actually compulsory

The rules on who must be insured are simpler than the anxiety around them suggests, and they hinge on how you hold the property.

If you rent, home insurance is compulsory — no exceptions. You must hold at least a risques locatifs / responsabilité civile policy, and you must produce the certificate at the état des lieux (the check-in inventory) before you get the keys, then again on request each year. No certificate, no keys; and a landlord can invoke the clause résolutoire to end the lease if you let cover lapse.

If you own a flat in a copropriété, you're legally required to carry at least responsabilité civile — liability cover — because a burst pipe in your flat becomes your neighbour's ruined ceiling, and the law wants someone on the hook for it.

If you own a detached house, standing on its own land — the classic British-in-France farmhouse — the law does not technically compel you to insure it. But this is the one place we'd urge you not to read "not compulsory" as "not necessary." French civil law makes you personally liable for damage that originates on your property: your tree comes down on the neighbour's car, your wall collapses onto the lane, and the bill is yours. A mortgage lender will require cover as a loan condition anyway. And if you ever let the place — even occasionally, even to friends — you'll want a propriétaire non-occupant (PNO) policy for the risks a tenant's own cover won't touch.

Don't buy liability cover twice

Here's a small saving that catches people out in the other direction. When a French school asks for an attestation de responsabilité civile for your child, or a club asks for one before your stage, the instinct is to rush off and buy a liability policy. Almost always, you don't need to.

Responsabilité civile vie privée — the household's private liability, covering you, your partner and your children for accidental harm to others — is bundled inside your multirisque habitation home policy already. The standard MRH packages fire, water damage, theft and that liability cover into one contract. So when the school asks, you don't buy anything; you log into your insurer's app and download the attestation, usually free and often the same day. Buying a standalone RC policy on top is simply paying twice for cover you already hold.

Health top-up is a different animal — and now escapable too

The mutuelle — the private top-up that covers the slice of healthcare the French state doesn't reimburse — is a separate market from home and car, with its own rules. For a long time it was not covered by the Loi Hamon, which trapped people in mutuelles they'd outgrown.

That changed on 1 December 2020. You can now cancel an individual mutuelle at any time after the first year, no reason required, no charge — exactly like home and car. (The exception: if your mutuelle comes through a French employer, the decision to switch sits with the employer, not you.) For the large British retiree audience this is worth knowing, because mutuelle needs change with age and the market moves; you're no longer stuck with the first one you signed. Our healthcare guide covers how the mutuelle fits alongside the S1, PUMAProtection universelle maladie — the scheme that gives legal residents access to French state healthcare. and the carte VitaleThe green card that makes French health reimbursements automatic at the doctor or pharmacy. in full.

The practical playbook

Pulling it together, here's how to actually run your French insurance rather than let it run you.

• Diarise the anniversary of every policy. Not because you must act then — Loi Hamon frees you after year one — but because it's the natural moment to check whether the premium has crept up.
• After twelve months, switch whenever you like. Take out the new policy, tick the mandat de résiliation box, and let the new insurer cancel the old one. No gap, no fee, no letter.
• If an insurer blocks you, check the Chatel reminder. Late or missing? You can leave immediately, with a refund.
• Use comparateurs for a first pass, then go wider. Cross-check two or three, then approach the big mutuelles and your own bank directly — they're often absent from the sites and often cheaper.
• Keep your attestation somewhere findable. You'll be asked for it at check-in, for the children's school, for a club — download it from the app rather than buying new cover.
• Never let car cover lapse. A gap isn't a paperwork problem, it's a criminal one. Always overlap the new policy's start with the old one's end.

Insurance law, the rules quoted and the market change, and how they apply depends on your own circumstances — your property, your status as tenant, flat-owner or house-owner, and the cover you need. Comparateur partner lists and insurer terms change over time. Always confirm current rules and cover with a qualified insurer or broker before acting, and read any policy's exclusions before you sign.
