Healthcare is one of the first legal issues a British national must settle after moving to France. The answer is not determined by nationality alone, by an EHIC or GHIC card, or by the fact that a private insurer has accepted an application. It depends on the date and legal basis of the move, the person\u2019s work or pension status, the applicable post-Brexit coordination rules, and evidence that France has become the person\u2019s stable and regular place of residence. The practical question is often urgent: how can a British resident obtain an S1, register it with the correct French health-insurance fund, receive an attestation de droits<\/em> (certificate of entitlement), and react if the Caisse primaire d\u2019assurance maladie<\/em> (CPAM, the local primary health-insurance fund) refuses or delays the file?<\/p>\n

This guide separates the S1 route from French affiliation under PUMa, explains why a temporary travel card is not a residence solution, and sets out a document and appeal strategy. It covers the individual and family member settling in France after Brexit, not the purchase of a French property or the creation of a company. For the wider first-year checklist, read the British desk\u2019s guide to moving from the UK to France after Brexit<\/a>. The focus here is narrower: healthcare registration, continuity of cover and a defensible response to a CPAM refusal.<\/p>\n

I. How do British residents obtain French healthcare after Brexit?<\/h2>\n

A. When does an S1 certificate, PUMa affiliation or private cover apply?<\/h3>\n

Begin by identifying the route before completing forms. An S1 is a certificate issued by the state responsible for a person\u2019s healthcare costs, confirming that the person is entitled to receive publicly funded healthcare in the country where he or she resides. For a British national, the United Kingdom may issue an S1 in circumstances such as receipt of a UK State Pension or another exportable benefit, a qualifying posting, or certain cross-border situations. The S1 is then registered with the French CPAM. It is not a French visa, it is not a residence permit, and it is not a tax-residence certificate. It is evidence of which state should bear the healthcare cost and of the basis on which France should provide care.<\/p>\n

The post-Brexit date matters. A British national who was lawfully resident in France by 31 December 2020 and remains within the same personal circumstances may be protected by the EU\u2013UK Withdrawal Agreement. The official French guidance distinguishes that protected population from people who moved later. A person insured in the United Kingdom under an S1 can register it in France and receive healthcare under the applicable coordination rules. The official Service-Public guide to health insurance for a foreigner settling in France<\/a> sets out the status-based approach, while the specific treaty and transition documents must be matched to the applicant\u2019s dates and evidence.<\/p>\n

A British citizen who moved to France from 1 January 2021 is generally assessed under the Trade and Cooperation Agreement and French domestic law, unless another instrument applies. The United Kingdom\u2019s official healthcare guidance for people living in France<\/a> identifies the main routes: French contributions through work or residence, an S1 registered with the local CPAM, and a GHIC or EHIC for necessary treatment during a temporary stay. Those routes are not interchangeable. A person who has made France the usual country of residence should not rely on a GHIC or EHIC as though it were a permanent registration document.<\/p>\n

A GHIC is a Global Health Insurance Card and an EHIC is a European Health Insurance Card. They can assist with medically necessary state healthcare during a temporary visit, subject to the applicable rules and conditions. They do not normally replace an S1 when the person is changing the country of ordinary residence. Service-Public\u2019s official guidance on the European health-insurance card<\/a> states the distinction in substance: when the usual country of residence changes, the S1 is the document used to register healthcare rights in the new country. A British resident who presents only a GHIC to a CPAM may therefore receive an answer that is legally correct for a visitor but irrelevant to a resident\u2019s application.<\/p>\n

If no United Kingdom S1 route applies, a person may enter the French system through employment, self-employment or residence-based affiliation. PUMa means protection universelle maladie<\/em>, France\u2019s universal health-protection scheme. It is not a separate insurance policy purchased from a private company. It links healthcare coverage to work or, where a person is not working, stable and regular residence in France, while contributions and patient participation can arise under the French rules. The official Service-Public guide to health insurance for a foreigner settling in France<\/a> presents different routes for workers, pensioners, students and jobseekers. A British applicant must select the route that corresponds to the facts instead of sending a generic request.<\/p>\n

The starting statutory rule appears in Article L. 160-1 of the French Social Security Code<\/a>. It provides: \u00ab 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. \u00bb In English, a person who works in France, or who does not work but resides there in a stable and regular manner, is within the statutory healthcare framework. The provision does not remove the need to prove the relevant status, residence or coordination instrument.<\/p>\n

For a non-working British resident who declares that no other scheme is covering healthcare, Article L. 160-5 of the Social Security Code<\/a> is especially important. It states: \u00ab Toute personne qui d\u00e9clare aupr\u00e8s d’une caisse primaire d’assurance maladie […] ne pas b\u00e9n\u00e9ficier de la prise en charge des frais de sant\u00e9 mentionn\u00e9e \u00e0 l’article L. 160-1 b\u00e9n\u00e9ficie de cette prise en charge aupr\u00e8s de cette caisse d\u00e8s qu’elle justifie de son identit\u00e9 et de sa r\u00e9sidence stable et r\u00e9guli\u00e8re. \u00bb The legal mechanism is therefore based on identity and residence evidence when the person does not already fall within another coverage route. It should not be presented as an automatic right to immediate reimbursement of every earlier bill: the dates, complete application, contribution position and applicable coordination rules still need to be established.<\/p>\n

The three-month evidence rule is more nuanced than the shorthand sometimes used online. Article D. 160-2 of the Social Security Code<\/a> says that applicants using Article L. 160-5 must produce evidence of uninterrupted residence in France for more than three months, subject to listed exceptions. Its opening wording is: \u00ab 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 \u00bb. Employees beginning French work, certain family members and other protected categories may be treated differently. A British pensioner with a valid S1 should not be pushed into the ordinary PUMa waiting analysis without first asking which state is competent for the pensioner\u2019s healthcare costs.<\/p>\n

Residence itself is a factual and legal question. Article R. 111-2 of the Social Security Code<\/a> provides the framework for stable residence. It describes the household as the place where people normally live, \u00ab c’est-\u00e0-dire du lieu de leur r\u00e9sidence habituelle \u00bb, and looks to the principal stay for the relevant benefits. The CPAM may examine leases, utility bills, tax documents, family life, work, schooling, travel and other consistent evidence. Do not send one recent electricity bill and assume that it answers the whole question. A person who travels between Britain and France should create a dated chronology explaining where the household was based during the relevant period.<\/p>\n

The distinction between S1 and PUMa also affects who may be asked to pay contributions. With an S1, the United Kingdom can remain the financially responsible state while France administers access to care. With PUMa, the French system may examine earned income, household resources and the contribution rules applicable to a person without employment. Article L. 160-13 of the Social Security Code<\/a> sets out the statutory framework for the insured person\u2019s participation in healthcare costs. The fact that a CPAM requests financial information is not, by itself, proof that the S1 has been rejected; it may indicate that the fund has opened the file under the wrong route or is checking whether another basis applies.<\/p>\n

That is why the first letter to CPAM should state the route in plain terms. For example: \u201cI am applying for registration of the attached UK-issued S1 as a resident of France.\u201d If no S1 exists, say: \u201cI am applying for affiliation under Article L. 160-5 of the French Social Security Code because I work in France\u201d or \u201cbecause I reside in France in a stable and regular manner and do not receive healthcare coverage from another state.\u201d The distinction makes the administration address the right legal question and gives an adviser or court a clear record if the response later becomes disputed.<\/p>\n

B. Which documents and residence evidence should be sent to CPAM?<\/h3>\n

A registration file should be designed so that a reader who did not attend the move can understand it. Put the documents in an index, number the pages and add a one-page chronology. The objective is not to send every paper ever received. It is to prove identity, the legal route, the French residence, the date from which the route applies and the practical contact details needed to administer the claim.<\/p>\n

For an S1 application, the core bundle normally includes the S1 itself, the British passport, the French residence document or evidence of lawful stay, proof of the French address, and documents showing the pension or benefit that led to the S1. If a spouse or dependant is included, provide the civil-status document linking the person to the insured holder and any separate entitlement evidence requested by the issuing authority. The UK authority may need to correct a name, date of birth or address before the CPAM can register the certificate. A scan should be legible, complete and accompanied by the reference number of the issuing service.<\/p>\n

For a PUMa request, use the current French application route indicated by the CPAM and provide the identity and residence information requested. The standard form is commonly known as the S1106, a request for entitlement to health-insurance benefits. The exact supporting documents can vary with nationality, family status, work, study, pension and immigration status. The applicant should check the current official instructions rather than rely on a form saved from a previous move. Where a French document asks for a justificatif de domicile<\/em>, meaning proof of address, provide a recent lease, utility statement, home-insurance certificate, tax document or another accepted document, with an explanation if the applicant is hosted by a family member.<\/p>\n

Residence evidence should cover the period that matters. Useful documents can include a signed lease, property-occupation evidence, electricity or water bills, home insurance, council or local tax records, French tax correspondence, bank activity showing ordinary life in France, medical appointments, school or family records, and travel evidence. No single document has magic status. The file becomes stronger when the documents tell the same story: the home is in France, the applicant actually lives there, and the move was not merely a series of short visits designed to obtain cover.<\/p>\n

If the applicant is employed in France, add the employment contract, payslips, employer certificate and the relevant social-contribution information. If self-employed, add the registration and evidence of the activity. If retired, add the UK State Pension award or payment statement, the S1 correspondence and the date from which the UK authority accepts responsibility. If the applicant has private insurance, attach the policy only to explain interim protection; a private policy does not by itself prove that the person is ineligible for French or coordinated public cover. If a person is a student or jobseeker, identify that status expressly because the governing route may be different.<\/p>\n

Prepare translations intelligently. A CPAM may accept documents in English in some situations, but a file involving a refusal, a family relationship, a pension category or a disputed residence period may require a French translation or a certified translation. Keep the original English document beside the translation and identify the translator. Do not translate a legal phrase into a convenient description that changes its meaning. \u201cState Pension\u201d, \u201coccupational pension\u201d, \u201cpublic-service pension\u201d, \u201cresidence permit\u201d and \u201chealth-insurance certificate\u201d should remain legally distinguishable.<\/p>\n

Send the file through a traceable channel. If the CPAM instructs the applicant to use an online account, retain the upload confirmation, screenshots, submission date and the list of documents attached. If the file is sent by post, use a method that proves delivery and preserve the receipt and delivery record. If documents are handed over at a reception desk, request a dated receipt. A telephone call can resolve a simple missing scan, but a call alone rarely proves what was requested or what the fund decided.<\/p>\n

Ask for two practical outputs: confirmation that the file is complete, and the reference number of the application. If something is missing, ask the CPAM to identify the exact document and the legal reason it is needed. A vague message such as \u201cyour file is incomplete\u201d should be answered with a short written request for clarification. At the same time, do not ignore an apparently minor request. A missing page of an S1, an inconsistent spelling or an absent proof of address can cause months of delay because the file is repeatedly placed back in an administrative queue.<\/p>\n

Until the carte Vitale<\/em>, the French health-insurance card, arrives, the applicant may receive an attestation de droits<\/em> or use the temporary number and paper reimbursement process indicated by the CPAM. The GOV.UK guidance on healthcare in France<\/a> warns that a carte Vitale can take time and explains that a patient may need to provide the temporary number and ask for a feuille de soins<\/em>, the paper treatment form, before the card is issued. Ask the doctor, pharmacist or hospital which document is required for the particular claim. Do not postpone medically necessary care simply because the plastic card has not arrived, but do not assume that every provider will process a bill in the same way.<\/p>\n

Keep a healthcare file separate from the tax and immigration files, while cross-referencing the same dates. The French residence permit may support lawful residence, a tax notice may support the household\u2019s location, and a pension statement may support S1 responsibility, but each document answers a different question. A coherent bundle prevents the CPAM from treating an immigration document as the only proof of residence or a pension payment as conclusive proof of healthcare entitlement.<\/p>\n

Finally, check the identity data before sending. The name on the S1, passport, residence document, bank account and French application should be reconciled. If a British person uses a middle name in one country and not the other, explain it. If the applicant has changed address, tell both the UK issuing authority and the CPAM. If a dependent has a different surname, add the birth or marriage certificate that explains the link. These are small points, but they are often the reason an otherwise valid S1 is not matched to a French file.<\/p>\n

II. What can you do when CPAM refuses or delays healthcare access?<\/h2>\n

A. How do you challenge a CPAM decision and preserve treatment or reimbursement rights?<\/h3>\n

First determine what has actually happened. A CPAM may have sent a formal refusal, asked for further evidence, suspended the review while another authority confirms an S1, issued a temporary number without a carte Vitale, or simply failed to answer. These situations require different responses. A telephone agent\u2019s statement that \u201cthe computer says no\u201d is not a reasoned decision. Ask for the decision in writing, the legal basis, the date of notification, the documents considered and the appeal instructions. Preserve the envelope, email metadata or account notification because the date can control the appeal period.<\/p>\n

A refusal can arise from a mismatch rather than an absence of entitlement. The CPAM may believe that the applicant is a visitor relying on a GHIC, may have treated a pensioner as a PUMa applicant, may not have connected a corrected S1 to the file, or may consider that the residence evidence covers only a recent week. The appeal should identify that precise error. It should not merely repeat that the applicant is British and has paid taxes in France. Nationality, tax residence, immigration status and healthcare responsibility overlap in the facts but are not the same legal test.<\/p>\n

For ordinary decisions within the social-security dispute route, the mandatory preliminary appeal is the commission de recours amiable<\/em> (CRA), meaning the internal amicable-appeal commission of the relevant social-security body. Article L. 142-4 of the Social Security Code<\/a> states: \u00ab Les recours contentieux form\u00e9s […] sont pr\u00e9c\u00e9d\u00e9s d’un recours pr\u00e9alable \u00bb. The purpose is not to turn a refusal into a negotiation without legal standards. It is the required gateway before the court for the matters covered by the provision. Sending a complaint to a general CPAM email address without identifying it as a CRA appeal can create an avoidable dispute about whether the correct preliminary remedy was used.<\/p>\n

The procedural rule is set out in Article R. 142-1 of the Social Security Code<\/a>. It provides that complaints falling under Article L. 142-4 are submitted to a CRA and that \u00ab Cette commission doit \u00eatre saisie dans le d\u00e9lai de deux mois \u00e0 compter de la notification de la d\u00e9cision \u00bb. Treat two months as a hard working deadline. If the notification is unclear, send the appeal promptly and explain the uncertainty. A late argument that the applicant was waiting for the UK authority, a translation or an informal reply may not repair the problem.<\/p>\n

A CRA appeal should contain a heading such as \u201cRecours pr\u00e9alable devant la commission de recours amiable \u2013 request to register S1\u201d and should state the decision being challenged. Attach the refusal, the S1, the application, the submission and delivery evidence, the identity and residence documents, the pension or employment evidence, and a chronology. Then set out the requested outcome: registration of the S1, correction of the affiliation basis, issue of an attestation de droits, reconsideration of a PUMa application, or written confirmation of the missing evidence. Ask the commission to identify any remaining document rather than leaving the request open-ended.<\/p>\n

Use the statutory language where it helps. If the dispute concerns an S1, identify the applicable Withdrawal Agreement or Trade and Cooperation Agreement route and explain why the United Kingdom remains the competent state for the cost of care. If it concerns PUMa, address stable and regular residence, the three-month rule and any exception. Cite Article L. 160-1<\/a>, Article L. 160-5<\/a> and Article D. 160-2<\/a> as appropriate. Do not cite every provision available if the facts do not engage it. A short, accurate appeal is stronger than a long list of unrelated articles.<\/p>\n

Silence also needs to be calculated. Article R. 142-6 of the Social Security Code<\/a> provides: \u00ab Lorsque la d\u00e9cision […] n’a pas \u00e9t\u00e9 port\u00e9e \u00e0 la connaissance du requ\u00e9rant dans le d\u00e9lai de deux mois, l’int\u00e9ress\u00e9 peut consid\u00e9rer sa demande comme rejet\u00e9e. \u00bb The starting point and the documents later supplied can affect the calculation. Keep proof of when the CRA received the appeal and of any later request or production of documents. If the two-month period has passed, do not wait indefinitely for an informal answer: ask for a written status and obtain advice on whether the deemed rejection has opened the next procedural step.<\/p>\n

The Court of Cassation has emphasised that the underlying French healthcare rules may apply \u201csans distinction de nationalit\u00e9\u201d in Second Civil Chamber, 3 June 2021, no. 20-10.687<\/a>. That case did not create an automatic post-Brexit route for every British resident; its facts and transitional legislation must be read carefully. It does, however, reinforce a useful point for an appeal: the administration should examine the statutory conditions and the evidence of the person\u2019s situation, not substitute nationality as a complete answer. A British claimant should therefore explain the precise condition met and the document proving it.<\/p>\n

If the refusal concerns the amount or collection of a PUMa contribution rather than the opening of healthcare rights, the financial dispute must be separated from the affiliation dispute. The Court of Cassation, Second Civil Chamber, 27 February 2025, no. 22-17.970<\/a>, dealt with the contribution mechanism and the requirement for the legal conditions to be examined. A contribution notice should be checked for the period, household resources, declared income, exemptions and the basis on which the CPAM or collecting body calculated it. An S1 holder should also ask why a French contribution is being requested and whether the UK certificate has been correctly recorded.<\/p>\n

There is a further distinction between an ordinary administrative refusal and a medical decision. A decision about incapacity, the medical necessity of a service or a professional medical assessment may use a medical appeal route, not the ordinary CRA route. If the letter is medical, read its appeal instructions before sending a standard registration appeal. If it combines an administrative refusal with a medical issue, separate the grounds and the deadlines. Sending the wrong appeal to the wrong body can consume the time that should have been used to protect the claim.<\/p>\n

Do not treat the appeal as a reason to stop paying for interim protection. A pending S1 registration or PUMa appeal does not automatically make a private policy unnecessary, and it does not guarantee that every invoice incurred before affiliation will be reimbursed. Ask the CPAM, the UK Overseas Healthcare Services and the provider what can be done while the file is being examined. If treatment is urgent, tell the provider that the administrative registration is pending, show the available entitlement evidence and request an itemised invoice and treatment form. The legal appeal and the practical continuity plan should run in parallel.<\/p>\n

B. Which evidence, deadlines and cross-border remedies protect your position?<\/h3>\n

A successful challenge usually depends on a timeline more than on the number of pages. Create a table with five columns: date, event, authority, document and consequence. Include the move to France, the first day of residence, the date of employment or pension entitlement, the S1 request and issue, each CPAM submission, every missing-document request, each reply, the first treatment or bill affected, and the date of the refusal. Mark the two-month CRA deadline in a calendar. If the person travelled to Britain, record those journeys honestly so that the residence analysis can be understood rather than attacked later.<\/p>\n

Evidence should answer the CPAM\u2019s likely objections. If the objection is \u201cyou are a visitor\u201d, show the French home, household, recurring bills and residence chronology. If it is \u201cthe S1 is not valid\u201d, obtain written confirmation from the UK issuing authority of the certificate\u2019s category, start date, dependants and competent-state basis. If it is \u201cyou have not lived in France long enough\u201d, address the statutory three-month rule and any exception with exact dates. If it is \u201canother state is responsible\u201d, explain employment, pension, posting or benefit status and attach the relevant decision. If the issue is a name mismatch, provide the civil-status evidence and ask for the record to be corrected.<\/p>\n

A person relying on the Withdrawal Agreement should prove both the historic residence position and the continuing factual circumstances. The residence card issued to a protected British national is important, but the card and the S1 answer different questions. A person who arrived after the transition period should not present a Withdrawal Agreement card that he or she does not hold, and a person protected by that agreement should not be forced into a later-mover analysis merely because an agent did not recognise the status. The official Service-Public healthcare guidance<\/a> and the GOV.UK France healthcare guidance<\/a> provide the accessible starting points, but the personal dates and status must be matched to the evidence.<\/p>\n

For a later move under the Trade and Cooperation Agreement, identify whether the British person is a pensioner receiving a qualifying UK benefit, a posted worker, a frontier worker, a French employee, a self-employed worker, a student, a jobseeker or a person relying on residence. The route may change after a new job, retirement, divorce, the end of a posting or the loss of an exportable benefit. The GOV.UK living-in-France guidance<\/a> should be read with the French rules, not used as a substitute for the CPAM\u2019s assessment. A change of personal status should be reported promptly to the relevant UK and French bodies.<\/p>\n

Continuity between competent institutions is a recognised legal concern. Article L. 160-18 of the Social Security Code<\/a> states: \u00ab En cas de changement d’organisme assurant la prise en charge des frais de sant\u00e9 d’une personne, l’organisme qui assure cette prise en charge ne peut l’interrompre tant que l’organisme nouvellement comp\u00e9tent ne s’est pas substitu\u00e9 \u00e0 lui. \u00bb The provision should not be over-read as a promise that a first application is automatically covered or that every disputed bill is payable. It does support a focused request where an already responsible scheme is being replaced or where the file is moving from one competent institution to another: identify the former institution, the new institution and the precise substitution date.<\/p>\n

When the CPAM says that the S1 has not arrived, contact the UK issuing service as well as the French fund. Ask for confirmation of whether the certificate was sent electronically or by post, the date sent, the recipient CPAM and whether a replacement certificate can be issued. Give the UK authority the French address and CPAM reference. If a temporary number has been created, ask whether the S1 can be linked to that number. Keep both sides informed in writing so that one authority cannot later say that the other was responsible for a missing transmission.<\/p>\n

If healthcare is needed before registration is complete, plan for reimbursement evidence. Ask the provider for a feuille de soins<\/em> or the electronic treatment record, retain prescriptions and invoices, and record the date of care. A hospital\u2019s administrative or social-work service may explain the immediate billing route. The patient should state that an entitlement application is pending and provide the S1 reference or CPAM application number, but should not sign a statement describing a permanent French affiliation if that has not yet been confirmed. Accurate wording prevents an interim form from being used later as evidence of a different legal status.<\/p>\n

Private insurance should also be read closely. Check the territorial scope, waiting periods, pre-existing-condition exclusions, direct payment arrangements, emergency definitions and termination date. A policy bought for a visa or for the first months after arrival may not cover planned treatment, chronic conditions or a family member. It may also contain a cooperation clause requiring the insured to notify the insurer of public cover. Keep the policy as part of the continuity file, but do not let it obscure the public-law question of which country is responsible for healthcare costs.<\/p>\n

French healthcare is not necessarily cost-free after registration. The patient may face co-payments, deductibles, regulated contributions or charges not reimbursed by the public scheme. A mutuelle<\/em> is supplementary private health insurance that can cover some of the remaining cost; it does not determine whether the CPAM must open the underlying rights. Before choosing a mutuelle, obtain the attestation de droits<\/em> and understand whether the person is registered on an S1 or under PUMa. The distinction can affect the policy\u2019s coordination and the documents requested at the point of treatment.<\/p>\n

An appeal should ask for a reasoned outcome, not just a card. If the claim succeeds, request written confirmation of the affiliation date, the identifier, the responsible institution, the status of dependants and the process for obtaining the attestation and carte Vitale. If only part succeeds, ask which part was refused and why. If the CRA remains silent, record the date on which the deemed rejection arose under Article R. 142-6 and obtain legal advice about the next step. A later court filing should attach the entire administrative record and show that the preliminary appeal was made within time.<\/p>\n

The social-security court route is not a second chance to submit an unstructured immigration file. The judge will need to see the decision, the applicable route, the evidence of status and residence, the appeal chronology and the remedy sought. A British applicant should explain whether the dispute is about eligibility, the competent state, the effective date, the amount of a contribution, reimbursement of a specific treatment or the administration\u2019s failure to process an S1. Those are different disputes even when the practical complaint is simply \u201cI cannot use my French health card\u201d.<\/p>\n

There may also be a cross-border coordination issue that should be raised with the issuing authority. If France and the United Kingdom each say the other must pay, ask for a written determination of the competent state and the legal instrument used. Do not rely on two telephone assurances that contradict one another. A dated request that cites the S1 category, the date of residence, the person\u2019s work or pension status and the healthcare invoices affected gives both authorities a question they can answer. Keep copies of every answer for the CRA and, if needed, the court.<\/p>\n

The most useful pre-appeal check is therefore a short decision tree:<\/p>\n
