You have done the hard part. You found the house in the Dordogne or the flat in Paris, you hold the right visa or the Withdrawal Agreement residence permit, and your boxes are on their way across the Channel. Then a neighbour asks the question that stops every British newcomer cold: what happens when you need a doctor? Since 1 January 2021, after the end of the Brexit transition period, British citizens are third-country nationals in France. You cannot rely on the National Health Service back home, and a British-issued card in your wallet does not automatically open the door to a French surgery. French law gives you two clearly marked doors into its health system. The first is the PUMA, the Protection universelle maladie<\/em>, France’s universal health cover, which takes in anyone who works in France or lives there in a stable and lawful way. The second is the S1 form, a British certificate that keeps your care funded by the United Kingdom while you live in France, principally for State pensioners and some cross-border workers. Both doors lead to the same local counter, the CPAM, the caisse primaire d’assurance maladie<\/em>, the local health insurance fund of the place where you live, and to the same green plastic card, the carte Vitale<\/em>, which you show at every appointment. This guide explains, in the order a British household actually meets them, who qualifies under each route, how registration with the CPAM works, what French healthcare really costs once you are covered, and how to challenge a refusal instead of accepting it.<\/p>\n

I. How a British resident gets French health cover after Brexit: PUMA affiliation or the British S1 form<\/h2>\n

A. PUMA: who qualifies, the stable-and-lawful residence test and the three-month rule<\/h3>\n

The PUMA is the default answer for most British residents, and its founding text is strikingly broad. Article L. 160-1 of the Social Security Code (Code de la s\u00e9curit\u00e9 sociale<\/em>) provides: “Toute personne travaillant ou, lorsqu’elle n’exerce pas d’activit\u00e9 professionnelle, r\u00e9sidant en France de mani\u00e8re stable et r\u00e9guli\u00e8re b\u00e9n\u00e9ficie, en cas de maladie ou de maternit\u00e9, de la prise en charge de ses frais de sant\u00e9 dans les conditions fix\u00e9es au pr\u00e9sent livre.”<\/a> In plain terms, anyone who works in France, or who lives in France in a stable and lawful way without working, is entitled to have health costs covered. The official service-public.fr guide confirms the point in English: if you work or reside in France on a stable and regular basis, the PUMA guarantees cover of your health costs in your own right and on an ongoing basis, even if your job or family situation later changes (What is Universal Health Protection (Puma)?<\/a>). One practical consequence matters immediately for couples: since the PUMA was created, an adult is covered in their own right and no longer needs to be registered as someone else’s dependant, the old ayant droit<\/em> status.<\/p>\n

If you work in France, the door opens at once. Article L. 111-2-2 of the same code affiliates to a compulsory French social security scheme, whatever their place of residence, all persons who work on French soil, whether for one or several employers, with or without a business premises in France, or who carry on a self-employed professional activity (Article L. 111-2-2<\/a>). The service-public.fr guide states that once the PUMA application of a person who works is accepted, enrolment with the French Health Insurance is immediate. Salaried staff are generally registered by their employer through the d\u00e9claration pr\u00e9alable \u00e0 l’embauche<\/em>, the pre-hiring declaration, and the self-employed through the Urssaf<\/em>, the body that collects social contributions. If you are a British employee hired locally on a French contract, your employer’s declarations put you into the system from the first day, and a British-issued EHIC or GHIC must not be used as a substitute once you live and work in France on that French contract, as the British government guidance expressly warns (Healthcare for UK nationals living in France<\/a>).<\/p>\n

If you do not work in France, two cumulative conditions decide your case: lawful residence (r\u00e9gularit\u00e9 du s\u00e9jour<\/em>) and stable residence (stabilit\u00e9 de la r\u00e9sidence<\/em>). Lawfulness is the Brexit point. A British citizen who wants to stay in France for more than three months must hold a residence document: article L. 411-1 of the Code on the Entry and Stay of Foreigners (Code de l’entr\u00e9e et du s\u00e9jour des \u00e9trangers et du droit d’asile<\/em>) states that “tout \u00e9tranger \u00e2g\u00e9 de plus de dix-huit ans qui souhaite s\u00e9journer en France pour une dur\u00e9e sup\u00e9rieure \u00e0 trois mois doit \u00eatre titulaire de l’un des documents de s\u00e9jour suivants”<\/a>, beginning with a long-stay visa. In practice this means a British newcomer shows a long-stay visa endorsed for residence, a temporary or multi-year residence card (carte de s\u00e9jour temporaire<\/em> or carte de s\u00e9jour pluriannuelle<\/em>), or, for those who were already settled before the end of 2020, the Withdrawal Agreement residence permit. The detailed test of stability and lawfulness is laid down by decree in Council of State, as article L. 111-2-3 recalls (Article L. 111-2-3<\/a>). Stability itself is defined by article R. 111-2: “sont consid\u00e9r\u00e9es comme r\u00e9sidant en France de mani\u00e8re stable les personnes qui ont leur foyer ou le lieu de leur s\u00e9jour principal sur le territoire m\u00e9tropolitain”<\/a>, in Guadeloupe, French Guiana, Martinique, R\u00e9union, Saint-Barth\u00e9lemy or Saint Martin. Your foyer<\/em> means the place where you normally live, and the CPAM checks it with bills, leases and tax notices rather than with promises.<\/p>\n

Stability also has a clock attached to it. Article D. 160-2 of the Social Security Code provides that “Les personnes qui demandent \u00e0 b\u00e9n\u00e9ficier de la prise en charge des frais de sant\u00e9 en application des dispositions de l’article L. 160-5 doivent produire un justificatif d\u00e9montrant qu’elles r\u00e9sident en France de mani\u00e8re ininterrompue depuis plus de trois mois”<\/a>, with proof possible through benefits paid under equivalent residence conditions or through the listed exemption categories. For a British family arriving in September, this means cover under the PUMA as a non-working resident normally starts once three months of continuous presence can be shown, while cover through work starts immediately. The courts apply this time condition strictly. In a widely reported decision of 3 June 2021, the Second Civil Chamber of the Court of Cassation, France’s highest civil court, recalled that claimants “peuvent produire un justificatif d\u00e9montrant qu’elle r\u00e9sident en France de mani\u00e8re ininterrompue depuis plus de trois mois ou qu’elles rel\u00e8vent de l’une des cat\u00e9gories qu’il \u00e9num\u00e8re limitativement”<\/a>, and it dismissed the appeal of a claimant who, having arrived in France on 10 March 2016, could not show uninterrupted residence of more than three months when she applied on 23 March 2016 (Cass. 2e civ., 3 June 2021, appeal no. 20-10.687, published in the Bulletin: “REJETTE le pourvoi.”<\/a>). The lesson for British newcomers is blunt: keep every dated proof of presence from day one, because the CPAM counts backwards from your application date.<\/p>\n

Registration itself is a paper file before it is a card. You apply to the CPAM of the place where you live, increasingly through an online Ameli account (Ameli<\/em> is the online portal of the French health insurance), and you attach proof of identity, proof of lawful stay such as your visa or residence card, proof of address, and, for a non-working applicant, proof of three months of stable presence. The CPAM examines the file, affiliates you, and then issues the carte Vitale<\/em>, the green chip card that surgeries and pharmacies read to bill the health insurance directly, a mechanism the French call tiers payant<\/em>, third-party payment, where you do not advance the covered part of the fee. Delays of several months are common in busy cities, so keep copies of everything you send and every receipt the CPAM gives you: if a refusal comes later, those papers are your evidence.<\/p>\n

B. The S1 form: which Britons stay funded by Britain and how to register it with the CPAM<\/h3>\n

The S1 is the second door, and it belongs to a different logic. Instead of joining the French system on French funding, some British residents receive their French healthcare with the bill sent back to the United Kingdom. The S1 is a portable certificate issued by the British authorities, and once registered with your local CPAM it entitles you to French state healthcare on the same terms as a French insured person, while the United Kingdom reimburses France for the cost. The mechanism comes from the European coordination regulations on social security, applied between the United Kingdom and France under the Brexit Withdrawal Agreement for persons already in cross-border situations, and under the EU-UK Trade and Cooperation Agreement for later cases. French law itself marks the boundary: article L. 160-6 of the Social Security Code excludes from the PUMA, among others, “Les personnes titulaires d’une pension \u00e9trang\u00e8re qui ne b\u00e9n\u00e9ficient pas par ailleurs d’un avantage viager d’un r\u00e9gime obligatoire de s\u00e9curit\u00e9 sociale fran\u00e7ais lorsque, en application d’un r\u00e8glement europ\u00e9en ou d’un accord international, la prise en charge de leurs frais de sant\u00e9 ainsi que de ceux des membres de leur famille qui r\u00e9sident avec elles rel\u00e8ve du r\u00e9gime \u00e9tranger qui sert la pension”<\/a>. In short, a British pensioner whose care falls to Britain under the coordination rules is not a PUMA member; they are an S1 holder.<\/p>\n

Three groups of British residents should check the S1 route first. The largest is British State pensioners living in France: if you draw a United Kingdom State pension and no French pension, you are normally entitled to an S1, and so are the dependent family members who live with you. The British guidance explains that once you hold the form, you must register it at your local CPAM office, and that information on registration is available through the Ameli portal in English (Healthcare for UK nationals living in France<\/a>; Ameli guidance in English<\/a>). The second group is frontier workers, people who live in France and work across the border, a pattern this site has already examined for British frontier workers whose S1 and A1 paperwork decides where contributions are paid (British frontier workers between a French home and a British job<\/a>); the same guidance invites frontier workers to check S1 eligibility with HM Revenue and Customs. The third group covers temporary situations: employees posted (d\u00e9tach\u00e9s<\/em>) by a British employer to France, who access care with a GHIC, an EHIC or an S1, and students, who should apply for a Student GHIC for medically necessary state care during their studies.<\/p>\n

Registration changes what sits in your wallet. After your S1 is recorded, you receive French cover and you may become entitled to a French-issued EHIC for travel, including visits back to the United Kingdom; conversely, you cannot use a British-issued EHIC for care in France once you live and work there on a French contract. Dependants follow the holder: the guidance warns that a dependant’s cover linked to a pensioner’s S1 ends when that dependant starts drawing their own United Kingdom State pension, at which point the health authorities send a new S1 to the registered address and it must be registered in turn to keep cover continuous. If registration drags on and urgent treatment cannot wait, the British guidance gives a concrete fallback: call the NHS Overseas Healthcare Services on 0044 191 218 1999 for help while the local file is stuck. For British pensioners who arrived before the end of 2020, one protection deserves underlining: the guidance confirms that United Kingdom nationals living in the European Union on or before 31 December 2020 keep their S1-based rights once the form is registered, which is the Withdrawal Agreement promise made tangible.<\/p>\n

II. What French healthcare costs a British resident and how to fight a refusal<\/h2>\n

A. Ticket mod\u00e9rateur, mutuelle, the CSM bill and means-tested top-up cover: what you really pay<\/h3>\n

French health cover always leaves part of the bill with the patient, unlike NHS care funded from taxation, and the vocabulary of that bill surprises every newcomer. The health insurance refunds care according to statutory tariffs, and the part left to the patient is called the ticket mod\u00e9rateur<\/em>. For routine care the insurance typically pays the larger share of the official fee and you pay the balance, plus any excess over the tariff if the practitioner charges above it, the d\u00e9passement d’honoraires<\/em>. Almost every French household therefore buys a private top-up policy called a mutuelle<\/em>, strictly a compl\u00e9mentaire sant\u00e9<\/em>, which refunds all or part of the ticket mod\u00e9rateur and the excess fees depending on the contract you choose. As a British resident you should budget for both: the compulsory cover through work contributions, the S1, or the PUMA, and a voluntary mutuelle whose price rises with age and with the level of refund. One administrative novelty should be watched: the service-public.fr guide notes that the Social Security Financing Act of 30 December 2025 introduces a financial contribution for some PUMA beneficiaries who meet three cumulative conditions, residence in France in a stable and lawful way being the first of them. The details belong to implementing decrees, but non-working British residents living on capital income should follow this development rather than discover it on a bill.<\/p>\n

The bill that actually shocks British early retirees even before any illness is the CSM, the cotisation subsidiaire maladie<\/em>, the subsidiary health contribution. Article L. 380-2 of the Social Security Code states that “Les personnes mentionn\u00e9es \u00e0 l’article L. 160-1 sont redevables d’une cotisation annuelle lorsqu’elles remplissent les conditions suivantes”<\/a>: professional income earned in France below a threshold fixed by decree, and no retirement or invalidity pension, no annuity and no unemployment benefit received during the year, with the spouse or civil partner’s situation examined under the same tests. The contribution is then levied on capital income, rental income and capital gains. A British couple retired early to France, living on dividends, rental income and realised gains while drawing no pension yet, is the textbook case. The Paris Court of Appeal confirmed on 27 June 2025 how firmly this contribution is enforced: it upheld against the contributor the contribution call and the formal demand, ruling in its operative part “D\u00c9CLARE r\u00e9gulier l’appel de cotisation subsidiaire maladie du 15 d\u00e9cembre 2017”<\/a> and “VALIDE la mise en demeure dat\u00e9e du 30 ao\u00fbt 2019”<\/a>, and it rejected the argument that the absence of actual affiliation or of actual cover removed liability (CA Paris, P\u00f4le 6, ch. 13, 27 June 2025, RG 22\/01239). Being inside the PUMA’s personal scope can therefore be enough to owe the CSM even in a year when the paperwork was never completed. The practical message for a British household living on investments is to declare the position correctly and to price the CSM into the cost of the French move, rather than to assume that no card means no bill.<\/p>\n

At the other end of the income scale, French law provides a genuine safety net. Article L. 861-1 of the Social Security Code opens a top-up health protection, the compl\u00e9mentaire sant\u00e9 solidaire<\/em>, to the persons covered by article L. 160-1: “Les personnes mentionn\u00e9es \u00e0 l’article L. 160-1 ont droit \u00e0 une protection compl\u00e9mentaire en mati\u00e8re de sant\u00e9”<\/a>, granted without any financial contribution where household resources sit below a ceiling fixed by decree, or against a capped contribution where resources fall between that ceiling and the same ceiling increased by 35 per cent, with the ceiling varying by household composition and revised each 1 April. A British resident of modest means who meets the PUMA residence conditions can therefore have the ticket mod\u00e9rateur and much of the excess wiped out through this scheme, applied for alongside or after the main affiliation. Between the CSM for households living on capital and the means-tested top-up for households of small means, the French system taxes health according to resources far more than British newcomers expect, and both mechanisms turn on the same gateway: being a person covered by article L. 160-1.<\/p>\n

B. CPAM says no: the papers that unblock your file and the court that overturns a refusal<\/h3>\n

Refusals follow a small number of scripts, and each has its answer. The most frequent is the three-month objection: the CPAM replies that stable residence is not shown. The Court of Cassation decision of 3 June 2021 discussed above is the measure of that fight: the claimant lost because, having arrived on 10 March, she applied on 23 March without three months of continuous presence and without falling into one of the exhaustively listed exemption categories, and the Court expressly approved the appeal judges for having “De ces constatations et \u00e9nonciations, la cour d’appel a exactement d\u00e9duit, sans encourir les griefs du moyen, ni statuer par des motifs susceptibles de constituer, \u00e0 l’encontre de Mme [P], une discrimination du fait de la nationalit\u00e9 de son conjoint, que l’int\u00e9ress\u00e9e ne pouvait, \u00e0 la date de la demande, pr\u00e9tendre \u00e0 son affiliation au r\u00e9gime g\u00e9n\u00e9ral de l’assurance maladie-maternit\u00e9”<\/a>. The same decision confirms, however, that the time condition applies without distinction of nationality and that the decree’s exemption categories must be examined one by one, which is where a well-built file wins: family reunification entries, refugee status, disability allowances and equivalent benefits can satisfy the stability test without delay, and the CPAM must say which category it examined and why it failed. A second script is the lawfulness objection, where the fund questions the residence document itself; here the answer is the visa or card plus proof of continuous presence, and for Withdrawal Agreement beneficiaries the specific permit, since lawful stay is assessed under the foreign-nationals legislation, not under the fund’s own impression. A third script hits S1 holders, where the CPAM delays recording the British form or asks for French-law documents the coordination rules do not require; the answer is the S1 itself with proof of deposit, the Ameli registration guidance, and, in urgent cases, the NHS Overseas Healthcare Services line. A fourth script is silence: months without an answer, which in French administrative practice must be met with registered follow-up letters that create the paper trail a judge will later read.<\/p>\n

When the file stays blocked, the remedy ladder is fixed. Start inside the fund: a written complaint (r\u00e9clamation<\/em>) to the CPAM, then an appeal to its internal appeals board, the commission de recours amiable<\/em>, within the stated time limit, attaching every missing proof the refusal letter mentions. If the board confirms the refusal, expressly or by silence, the dispute moves to court: social security disputes go to the social division (p\u00f4le social<\/em>) of the judicial court (tribunal judiciaire<\/em>) of your place of residence, where a judge re-examines the whole file and the court’s decision replaces the fund’s. The Paris S1 and CSM litigation shows this path working in both directions: contributors contest calls before the board and then before the social courts, and the courts decide the substance, validating a regular call or annulling an irregular one. Time limits are short, generally two months from the board’s decision, so a refusal letter should be dated, kept and answered immediately rather than filed away. British readers used to ombudsmen should understand the difference: the internal board is mandatory and quick, but only the judge can finally overturn the fund, and legal aid (aide juridictionnelle<\/em>) exists for households of small means.<\/p>\n

Two Paris and \u00cele-de-France points close the practical picture, since so many British households settle in the capital region. First, register with the CPAM of your actual home, in Paris through the Ameli channel of the Paris fund, and expect longer processing times than in a rural department: file early, before the three-month point if you are a non-working applicant, so that affiliation starts as soon as the condition is met rather than months later. Second, if you arrived as a retiree on a long-stay visitor visa, remember that the visa required private health insurance for the first year, a point examined for British retirees on visitor visas (British retirees in France on a visitor visa<\/a>); that private cover does not replace the PUMA application once residence becomes stable, and the CPAM cannot reject you merely because an insurer already covers you. Keep the insurer’s certificate for the visa file and build the CPAM file in parallel, because the two systems answer different questions.<\/p>\n

Conclusion<\/h2>\n

French healthcare after Brexit asks every British household the same two questions in the same order. First, which door is yours: the PUMA, if you work in France or live there in a stable and lawful way, or the British S1 form, if a United Kingdom pension or a cross-border working pattern keeps your care funded from London. Second, can you prove it on paper at the CPAM counter: a residence document for lawfulness, three months of dated presence for stability unless an exemption applies, or a registered S1 with its deposit receipt. Behind those questions stand real costs, from the ticket mod\u00e9rateur and the mutuelle to the CSM bill on capital income and the means-tested top-up for small households, and real remedies, from the internal appeals board to the social judge who decides the whole dispute afresh. File early, keep every dated proof, and treat a refusal as the start of a procedure with rules and time limits, not as a final answer.<\/p>\n","protected":false},"excerpt":{"rendered":"
