You have sold up in Manchester, bought a stone house outside Bergerac, and collected your withdrawal agreement residence card from the préfecture. Then your daughter needs an asthma inhaler renewed, you need a blood test, and the local doctor’s receptionist asks for your carte vitale, which is the small green plastic card every resident in France shows at each visit to a doctor, a pharmacy or a hospital so the health fund repays its share automatically. You have no card, no French social security number, and a letter from the CPAM, the caisse primaire d’assurance maladie, which is the local health fund office that registers residents and repays treatment, telling you that your file is incomplete or refused. This is the moment where many British households in France lose months and pay treatment out of pocket that the law would have covered, because they applied through the wrong route, proved the wrong facts, or accepted a refusal that a court would have overturned.
There are only two lawful doors into French state healthcare for a British resident after Brexit, and you must choose the right one before you argue. The first door is the S1 form, which is a certificate issued by Britain stating that the United Kingdom pays for your healthcare while you live in France, used by state pensioners, posted workers and some frontier workers. The second door is the PUMA, the protection universelle maladie, which is the universal residence-based cover that France gives to anyone working in France or living here in a stable and regular way. This article explains each door with the exact articles of the Social Security Code, the official British guidance, and two court decisions that show how judges decide, then sets out precisely how to challenge a CPAM refusal, from the friendly appeal to the courtroom, and how to live safely while you wait for the green card.
I. The two doors into French healthcare for a British resident after Brexit
A. When Britain keeps paying for your care: the S1 certificate registered with the CPAM
The S1 route is the simplest outcome a British household can obtain, because France does not examine your resources, your months of presence or your residence card where this certificate applies: Britain remains the state that funds your treatment, and the French fund merely registers you and delivers care. The official British guidance on healthcare in France states the rule plainly: once the S1 form is issued, it has to be registered at the CPAM office of your home address, and the same guidance confirms that starting to draw a UK State Pension can open the right to an S1, which is the most common trigger for retired British residents in France. Posted workers sent temporarily by a British employer, frontier workers who work in one state and live in another, and people receiving an exportable British benefit use the same document, each category on its own conditions.
Where the coordination rules make one state alone competent for your social security, that single-state logic protects you against being bounced between two funds. The Cour de cassation, the highest French civil court, recalled the mechanism in its judgment of 29 May 2019, pourvoi No R 18-13.679, given in a dispute about dual affiliation, where it opened its reasoning with “Vu l’article 87, § 8, du règlement (CE) n° 883/2004 du Parlement européen et du Conseil du 29 avril 2004 sur la coordination des systèmes de sécurité sociale”, and then quoted the transitional rule that “cette personne continue d’être soumise à la dernière législation aussi longtemps que la situation qui a prévalu reste inchangée”, meaning that a person who falls under a new coordination regulation keeps the earlier applicable legislation while the underlying situation is unchanged. The full text of that decision is published at Cour de cassation, Second Civil Chamber, 29 May 2019, No 18-13.679. For a British reader the practical translation is this: where Britain has issued you an S1 as a state pensioner or a posted worker, France cannot treat you as an uninsured newcomer who must first prove three months of residence, because your cover already exists and only needs registration.
The application path for pensioners is administrative rather than judicial. The British guidance explains that a person drawing a UK State Pension or another qualifying exportable benefit applies for the certificate through NHS Overseas Healthcare Services, which is the British office that issues S1 certificates to people living abroad, with the application request made by phone. Once the certificate arrives, registration happens at the CPAM of your home address in France, with your passport, proof of address, birth certificate, residence permit and the S1 itself. Keep a copy of everything and ask the CPAM counter for a dated receipt or an attestation de droits, which is the paper certificate of entitlement that proves your cover while the plastic card is being made. Where the CPAM tells a pensioner to apply under the residence-based PUMA instead of registering the S1, that redirection is suspect: an S1 holder is covered by another state’s scheme by definition, and the residence route is designed for people with no other cover.
Dependants need separate attention. A spouse or child can in many cases be registered as an ayant droit, which is the French term for a dependant who draws rights through an insured person, on the S1 holder’s certificate, but the British guidance warns that cover linked to one person’s status can end when that status changes, for example where a dependant of a worker starts drawing their own State Pension. Check whose name each attestation bears, register every member of the household individually, and never assume that one certificate covers the whole family without each person appearing on the CPAM file. Where the British authority refuses to issue an S1, ask for the refusal in writing with reasons, because that letter becomes the key exhibit if you then turn to the second door, the PUMA, and must prove that no other state’s scheme covers you.
B. When France covers you because you live here: the PUMA residence route
Where no S1 applies, French law covers you because you live in France, and the founding promise is written in broad terms. Article L111-2-1 of the Social Security Code declares that “La Nation affirme son attachement au caractère universel, obligatoire et solidaire de la prise en charge des frais de santé assurée par la sécurité sociale”, which means that the nation affirms its attachment to the universal, compulsory and solidarity-based character of the coverage of health costs by social security. The operative right follows in Article L160-1 of the Social Security Code: “Toute personne travaillant ou, lorsqu’elle n’exerce pas d’activité professionnelle, résidant en France de manière stable et régulière bénéficie, en cas de maladie ou de maternité, de la prise en charge de ses frais de santé dans les conditions fixées au présent livre”, meaning that any person working, or, where they carry on no occupation, residing in France in a stable and regular manner is entitled to coverage of health costs in case of sickness or maternity. The official service-public.fr explainer confirms the promise in plain language: once you work or reside in France in a stable and regular way, the PUMA secures coverage of your health costs on a personal and continuous basis. Two adjectives therefore decide everything, stable and regular, and each has its own decree-level definition that the CPAM applies file by file.
Stability is the easier condition and the one most British files prove without difficulty. Article R111-2 of the Social Security Code provides that “sont considérées comme résidant en France de manière stable les personnes qui ont leur foyer ou le lieu de leur séjour principal”, which means that the persons treated as residing in France stably are those whose home or principal place of stay is in France, a rule the rest of the article extends to metropolitan France and named overseas territories for the listed benefits. In practice the CPAM wants proof of uninterrupted residence for more than three months, and Article D160-2 of the Social Security Code states that claimants “doivent produire un justificatif démontrant qu’elles résident en France de manière ininterrompue depuis plus de trois mois”, meaning they must produce evidence showing uninterrupted residence in France for more than three months. A signed lease, quarterly electricity and water bills, home insurance certificates, school enrolment letters and dated travel tickets form the standard bundle, and the file should show presence, not mere ownership: a British owner who visits a Dordogne holiday home for a few weeks each season does not reside in France, while a British tenant present every day for four months does.
Regularity is the condition that causes most British refusals, because Brexit turned British citizens into third-country nationals for stay purposes. Article R111-3 of the Social Security Code limits the residence-based benefits to “les personnes qui sont de nationalité française ou sont en situation régulière au regard de la législation sur le séjour des étrangers en France”, meaning persons of French nationality or in a regular position under the legislation on the stay of foreign nationals in France, provided they are not already covered by another state’s scheme under European regulations or international conventions. A ministerial order lists the qualifying permits and documents for non-European nationals, and for a British resident that normally means a withdrawal agreement card, a long-stay visa validated on arrival, or a residence permit, held on the day of the application. The same article adds a timing rule that many refusals ignore: “La condition de régularité du séjour des personnes est appréciée au jour de la demande présentée pour bénéficier des dispositions du premier alinéa du I”, meaning regularity is assessed on the date of the application, so a permit that expires while the CPAM is still examining the file does not retroactively destroy a valid application.
Two boundaries complete the picture and both generate refusals that need careful reading. First, the jobseeker exclusion: Article L160-6 of the Social Security Code removes from the residence-based cover “Les ressortissants des Etats membres de l’Union européenne et des autres Etats parties à l’accord sur l’Espace économique européen ou de la Confédération suisse, entrés en France pour y chercher un emploi et qui s’y maintiennent à ce titre”, meaning nationals of EU and EEA states and Switzerland who entered France to look for work and remain on that basis. This targets people whose very ground of presence is job seeking, not a British spouse who joined a partner and later registered as a jobseeker to integrate, a distinction the courts enforce, as the second part of this article shows. Second, the content of the cover once affiliated is wide: Article L160-8 of the Social Security Code states that “La protection sociale contre le risque et les conséquences de la maladie prévue à l’article L. 111-2-1 comporte : 1° La couverture des frais de médecine générale et spéciale, des frais de soins et de prothèses dentaires, des frais pharmaceutiques et d’appareils”, meaning the cover includes general and consultant medicine, dental care and prostheses, pharmacy and appliances, plus hospital and related costs detailed in the rest of the article. Where household resources are modest, Article L861-1 of the Social Security Code adds that “Les personnes mentionnées à l’article L. 160-1 ont droit à une protection complémentaire en matière de santé”, meaning the persons covered by Article L160-1 are entitled to top-up health protection, the means-tested complémentaire santé solidaire that pays the share the basic scheme leaves behind. And where work stops, Article L161-8 of the Social Security Code keeps cash benefits running for a period fixed by decree for people who “cessent de remplir les conditions d’activité requises pour l’affiliation”, meaning who stop meeting the occupation conditions for affiliation, provided residence and stay conditions remain met.
II. When the CPAM says no: challenging the refusal and living without the card
A. How British residents overturn a CPAM refusal: the friendly appeal and the social court
A CPAM refusal letter is the start of a procedure, not the end of your rights, and the first step is compulsory. Article L142-4 of the Social Security Code requires a prior appeal before any court action in these matters, and Article R142-1 of the Social Security Code fixes the machinery: claims go to the caisse’s commission de recours amiable, which is the friendly appeals board inside each fund, and “Cette commission doit être saisie dans le délai de deux mois à compter de la notification de la décision contre laquelle les intéressés entendent former une réclamation”, meaning the board must be seized within two months of notification of the contested decision. Send the appeal by registered letter with acknowledgement of receipt, attach every missing or disregarded exhibit with an inventory, and ask expressly for a reasoned decision that answers each of your points, because a vague confirmation is harder to defend for the fund and easier to attack for you. Where the board rejects the appeal or stays silent past its deadline, the dispute moves to the pôle social of the tribunal judiciaire, which is the social division of the local civil court that hears benefit disputes, within the time limit printed on the board’s decision, so diary that date on receipt and instruct counsel at once rather than after expiry.
The most useful recent illustration of how these cases are won is a judgment that reads like a checklist of CPAM errors. On 13 March 2026 the social division of the Boulogne-sur-Mer court, file No 25/00157, decided the claim of a woman whose CPAM had refused residence-based affiliation, and the full judgment is published at Tribunal judiciaire de Boulogne-sur-Mer, Pôle social, 13 March 2026, RG No 25/00157. The fund had argued three points familiar to any British applicant: the claimant was in an irregular stay position, she was a jobseeker excluded from cover, and her registration with the employment service proved it. The court recalled the principle first, holding that “En application des dispositions de l’article L. 111-1 du code de la sécurité sociale, la sécurité sociale est fondée sur le principe de solidarité et assure, pour toute personne travaillant ou résidant en France de façon stable et régulière, la couverture des charges de maladie, de maternité et de paternité ainsi que des charges de famille et d’autonomie”, meaning social security is founded on solidarity and covers every person working or residing in France in a stable and regular way. It then dismantled the irregularity argument: the claimant had joined her partner, an EU citizen with payslips, a tax notice and health insurance, and the court treated her as a family member in a regular position, adding that the fund could not validly claim otherwise.
The jobseeker point received the same treatment and deserves close attention from British households, because CPAM offices routinely invoke job-centre registration as proof of exclusion. On the facts, the court held that she had not entered France to look for work and remain on that basis, but to join her partner, noting that she arrived in May 2023 and only registered with the employment service the following December, which corroborated integration after arrival rather than a job-seeking entry. Stability was proved by the tenancy signed in August 2023 with rent receipts showing uninterrupted residence beyond three months. The outcome was total: the operative part declared that she met the residence-based affiliation conditions and ordered the Côte d’Opale fund to register her on that basis, with costs against the losing fund.
Translate that judgment into a British file strategy. Where the CPAM calls you irregular, answer with the permit held on the application date, the partner’s status and resources where you joined family, and the rule that regularity is judged on that date, not on later expiry during examination. Where the fund brands you a jobseeker, reconstruct the timeline with dated tickets, the lease, and the late employment-service registration to show that work-seeking followed settlement instead of causing it. Where the fund says your stay is unstable, produce the lease plus three months of utility bills, insurance and school or medical letters rather than a single document. And where the fund pushes a pensioner or posted worker towards the PUMA instead of registering an S1, reply with the S1 and the single-state logic, because a person already covered by Britain is outside the residence route by construction. File the friendly appeal within the two months, keep every envelope and receipt, and put the court in a position to order affiliation exactly as Boulogne did, rather than merely annulling a badly reasoned refusal.
B. How British households live safely while the card is being made: numbers, paper claims and travel cover
Registration is only half the battle, because the plastic card arrives long after the right exists, and the British guidance is blunt about the wait, warning that the carte vitale can take six months or longer to arrive. The same guidance gives the survival instruction for the interval, advising patients who need treatment before the card arrives to use their social security number instead. Your numéro de sécurité sociale, which is the lifelong personal number the CPAM assigns once your file is accepted, unlocks care immediately, and the attestation de droits proves the number to every practice. Where the doctor cannot read the card electronically, ask for a feuille de soins, which is the paper treatment form the practitioner signs so you can post it to the CPAM for repayment of treatment you paid for upfront. Keep copies of each form, note the posting date, and chase repayment after six weeks, because paper claims are the ones that go astray.
Three practical settings need separate organisation. First, employment: new workers are told to apply for their social security number at the local CPAM office as soon as work starts, and the British guidance adds that private cover should bridge the registration gap, since an employer declares you but the number and card still take time. Check the first payslip for the employer’s declaration, keep the employment contract with the CPAM file, and remember that a change of employer or a move to self-employment is a change to notify, not a new three-month wait where residence continues. Second, the household budget: French state cover repays a share, not everything, and the part left behind, the ticket modérateur plus any excess fees charged by practitioners outside the regulated tariff, stays with you unless a top-up policy pays it. Compare a private mutuelle, which is the voluntary top-up health policy most French households hold, with the means-tested state top-up under Article L861-1, and take care before cancelling British private cover: leaving a gap uninsured while the CPAM examines your file is precisely when an accident happens. Third, travel: for temporary stays use a British GHIC or EHIC, which are the cards Britain issues for necessary treatment during short visits abroad, never as a substitute for French residence cover, while posted workers use the GHIC, EHIC or S1 according to their posting papers, and once France has affiliated you, a French-issued EHIC for travel including visits back to Britain can follow.
Paris and the Île-de-France region add no separate health-fund law but change the practical timetable, because CPAM counters in the capital handle far larger volumes and appointments run slower, so file early, use the online account the moment the provisional number arrives, and choose a médecin traitant, which is the named GP gatekeeper whose referral keeps your repayments at the full rate, near your home rather than near a former London habit. Keep the Withdrawal Agreement residence card, the S1 or its written refusal, the lease and utility bundle, and every CPAM receipt in one folder, paper and scanned, because the fund that loses a document will ask you to prove it twice. And treat every deadline as substantive: the two months for the friendly appeal, the limit printed on the board’s reply for the court, and the yearly renewal of any top-up or private policy, since lapsed cover is the fact the other side always discovers.
Conclusion
A British household settles its French healthcare where it answers three questions in the right order with papers to match. Which door is yours: the S1 where Britain funds your care as a pensioner, a posted worker or a frontier worker on the proper certificate, or the PUMA where France covers you because you work here or reside here stably and regularly with the permit held on the application date and three months of presence proved. What does the fund’s refusal really say: a genuine missing document to supply, or one of the three standard errors, misjudged regularity, invented instability, or a jobseeker label stuck on someone who joined family and only later looked for work, each of which the Boulogne judgment shows a court will correct where the exhibits prove the facts. And how do you live meanwhile: the social security number and the paper treatment form from day one, a top-up policy or the state top-up for the unpaid share, and the right travel card for each journey, while the friendly appeal runs within its two months and the court stands behind it. Keep the permits, the S1, the lease bundle and every receipt, answer each refusal point by point, and the green card becomes the formality it was meant to be.
