You drove off the ferry at Calais with your UK-plated car, all your belongings in the boot, and a new life waiting in France. Weeks later the car is still on its British plates, the post from the DVLA has stopped, and a neighbour warns you that the gendarmes are less patient than they used to be with foreign registrations. Since Brexit, bringing a British car to live in France is no longer an internal European move. The United Kingdom is a third country for customs purposes, which means your car must pass through French customs, pay import VAT and in most cases customs duty, and then be registered for French plates within a strict one-month window. Miss a step and you face an ANTS refusal, an immobilised car, or a fine that grows every day the file sits idle. This guide walks you through the whole chain in order: what to do with the DVLA before you leave Britain, how to clear French customs and secure the famous 846A clearance certificate, how to assemble an ANTS file that gets accepted first time, and exactly what to do when the administration says no.
I. Getting Your UK Car Into France Lawfully After Brexit: Customs, Tax and the Papers ANTS Will Demand
A. How Long Can You Keep Your British Plates, and What Must You Sort With the DVLA Before You Leave?
Start on the British side, because French customs will later ask for the very documents you handle at this stage. If you are taking your car out of the United Kingdom for twelve months or more, the move counts as a permanent export and you must tell the Driver and Vehicle Licensing Agency, the DVLA, the British authority that keeps the vehicle register. The official guidance treats a car taken out of the United Kingdom for twelve months or more as a permanent export that must be notified to the DVLA. In practice you complete the permanent-export section of the V5C log book, the British registration document, detach it and post it to the DVLA in Swansea, keeping the rest of the log book, since the French authorities will ask for that remainder when you register the car in France (GOV.UK guidance on taking a vehicle out of the United Kingdom). If a vehicle-tax refund is due, it usually arrives within four to six weeks, calculated from the date the DVLA receives your declaration. Do this before you sail, because the DVLA cannot send a log book to an address outside the United Kingdom, and arriving in France without the V5C makes every later step harder.
Once in France, the decisive question is whether you are a visitor or a resident. A British tourist touring the Dordogne for three weeks keeps his UK plates without difficulty. A British national who has settled in France, taken a lease, enrolled children at school or obtained a residence permit is a French resident, and a resident may not drive indefinitely on foreign plates. The National Agency for Secure Documents, known as ANTS (Agence Nationale des Titres Sécurisés), the online portal that now handles every registration, states the rule plainly: a foreign vehicle must be registered within one month of arrival. One month from the moment the car enters France with a resident owner, the file for French plates must be lodged. That deadline is the spine of your whole timetable, because customs clearance, the certificate of conformity and the roadworthiness test all have to fit inside it or be well under way before it expires.
The legal foundation is straightforward. French law defines its terms broadly: “Le terme “véhicule à moteur” désigne tout véhicule terrestre pourvu d’un moteur de propulsion, y compris les trolleybus, et circulant sur route par ses moyens propres, à l’exception des véhicules qui se déplacent sur rails” (Article L110-1 of the Code de la route). Your British saloon, your motorbike and even your caravan trailer fall inside that definition, and all of them are subject to registration. The obligation itself is set by Article R322-1 of the Code de la route: “Tout propriétaire d’un véhicule à moteur autre qu’un cyclomobile léger, d’une remorque dont le poids total autorisé en charge est supérieur à 500 kilogrammes ou d’une semi-remorque et qui souhaite le mettre en circulation pour la première fois doit faire une demande de certificat d’immatriculation en justifiant de son identité”. The carte grise, the French vehicle registration certificate, is therefore not optional paperwork. It is the document that identifies the vehicle and authorises it to circulate, and the same article requires you to show insurance, a matching driving licence and conformity of the vehicle when the administration asks.
Insurance deserves immediate attention because it is checked at every stage. Before the ferry, confirm in writing that your British insurer covers permanent residence in France; most annual UK policies cover only visits, typically up to ninety days, and some exclude a car that has been permanently exported altogether. French law is uncompromising: “Toute personne physique ou toute personne morale autre que l’Etat, dont la responsabilité civile peut être engagée en raison de dommages subis par des tiers résultant d’atteintes aux personnes ou aux biens dans la réalisation desquels un véhicule est impliqué, doit, pour faire circuler celui-ci, être couverte par une assurance garantissant cette responsabilité” (Article L211-1 of the Code des assurances). Take out French cover as soon as the car sleeps in France, keep the certificate in the vehicle, and remember that driving without it is a criminal offence punishable by a 3,750 euro fine, as Article L324-2 of the Code de la route provides: “Le fait, y compris par négligence, de mettre ou de maintenir en circulation un véhicule terrestre à moteur ainsi que ses remorques ou semi-remorques sans être couvert par une assurance garantissant sa responsabilité civile conformément aux dispositions de l’article L. 211-1 du code des assurances est puni de 3 750 euros d’amende.” Negligence is no defence, so an expired British policy is as dangerous as no policy at all.
B. How Do You Clear French Customs, Pay Duty and VAT, and Obtain the 846A Clearance Certificate?
This is the step that surprises most British newcomers, because before Brexit it did not exist. A car arriving from Manchester is now arriving from outside the European Union, and French customs treats it like a car arriving from America or Japan. You must present the vehicle to a customs office, a bureau de douane, lodge an import declaration and pay the duties and taxes before any registration is possible. The reason lies in the tax code: “Les importations de biens sont soumises à la taxe sur la valeur ajoutée” (Article 291 of the Code général des impôts), and an import expressly includes “l’entrée en France d’un bien, originaire ou en provenance d’un Etat ou d’un territoire n’appartenant pas à l’Union européenne, et qui n’a pas été mis en libre pratique”. Your UK-registered car, which has never been cleared for Union-wide circulation since Brexit, matches that definition exactly. The rate is the standard French rate: “Le taux normal de la taxe sur la valeur ajoutée est fixé à 20 %” (Article 278 of the Code général des impôts).
Customs duty may apply on top of VAT, depending on the origin of the vehicle and the proof you can produce. The Franco-British position is governed by the EU-UK Trade and Cooperation Agreement, which allows zero duty for goods that genuinely originate in the United Kingdom when origin is documented, while non-originating vehicles bear the common tariff. Whatever the rate, customs calculates it on the ex-VAT value of a standard vehicle plus extras such as transport costs and options. Bring every document that establishes value and origin, because the office assesses duty and tax on your declarations and supporting papers. At a minimum, hand over the foreign registration certificate or an equivalent official document and, where there was a sale, the purchase invoice, which means your V5C log book or equivalent and the bill of sale or transfer certificate (French customs guidance on buying a vehicle outside the European Union). If the car travelled under an external transit document, add that too. One practical warning from customs: the foreign plates on the cleared vehicle must still be valid. Expired British plates, plates copied onto French-style blanks, or any registration that does not comply with Article R317-8 and R322-3 of the Code de la route will be rejected at the counter, so keep the UK registration live until clearance is granted.
After payment, customs hands you three things: a copy of the customs declaration, a receipt, and the document your whole registration depends on, the 846A customs clearance certificate, the certificat de dédouanement, which proves the duties and taxes were paid and must be shown to the registration service where the car will be plated. The 846A is the British importer’s equivalent of the quitus fiscal that intra-European buyers know. Do not confuse the two. The quitus fiscal, the tax clearance slip, shows the vehicle is in order for VAT purposes (service-public.fr guidance on the quitus fiscal), but it is issued by the tax office for vehicles bought inside the European Union, whereas a car from Great Britain must go through customs and produce the 846A. ANTS confirms the split by asking for the quitus only for vehicles arriving from Europe. Filing a quitus request for a Manchester car wastes weeks; filing the 846A is the correct route.
There is one major exemption, and it covers the classic case of the family that ships its whole household across the Channel. If you lived outside the European Union for more than a year and you move your normal residence to metropolitan France for good, “your vehicle is admitted free of duties and taxes provided it appears on the duplicate inventory of your effects and meets three conditions: it must not be a commercial vehicle, it must have been in your possession and use for more than six months, and the taxes normally due in the country of origin must have been paid (French customs guidance on transfer-of-residence relief). List the car on the typed inventory of your effects in duplicate, prove six months of ownership and use with insurance records and the V5C history, and the transfer-of-residence relief wipes out both duty and import VAT. Note the trap hidden in the relief: sell the car within twelve months of the franchise and customs will reclaim the suspended taxes, so keep the vehicle for the full year.
Conformity is the second half of customs and registration alike. A standard British-market car built for the European market usually holds a European certificate of conformity, the document in which the manufacturer certifies the type, and ANTS asks for it in every file. Right-hand drive itself is not a ground for refusal, but the headlamps of a UK car dip to the left and will dazzle on French roads, so budget for a headlamp change or certified beam deflectors before the roadworthiness test. If the car has been substantially modified, fitted with non-approved parts or built in small series without European type approval, it must go through individual approval, the réception à titre isolé before the regional environment authority, the DREAL. The rule is strict: “Tout véhicule isolé ou élément de véhicule ayant subi des transformations notables est obligatoirement soumis à une nouvelle réception” (Article R321-16 of the Code de la route). Book that inspection early, because its report joins the ANTS file and its waiting lists are the longest in the chain.
II. Registering Your UK Car for French Plates and Challenging an ANTS Refusal
A. How Do You Get the Carte Grise: Conformity, Roadworthiness Test, Insurance and the One-Month Clock?
Registration happens exclusively online through your ANTS account, reached via FranceConnect, the state single-sign-on. Select the first-registration procedure for a vehicle bought abroad, enter the vehicle identification number, the VIN stamped on the chassis, and upload the supporting documents in digital form. The standard bundle has five items: the Cerfa 13750 application form, valid identity documents, the manufacturer’s certificate of conformity or equivalent, proof of address in France less than six months old, and the tax paper, meaning the 846A clearance certificate for your British car. If someone files for you, add a signed mandate and that person’s identity document. Then the file goes to an examining officer, the instructeur, and the waiting begins: a few days for a clean file, several weeks for a complicated one. Watch the status screen, because “en instruction” means analysis is under way, “à compléter” means the officer wants an extra document and the clock is running against you, “en attente de paiement” means the registration taxes are ready to pay by bank card, and “demande rejetée” means refusal with reasons you must answer.
The roadworthiness test, the contrôle technique, catches many British files. France requires it for light vehicles four years after first circulation and then every two years: “Les véhicules légers définis au II de l’article R. 323-6 doivent faire l’objet : 1° D’un contrôle technique dans les six mois précédant l’expiration d’un délai de quatre ans à compter de la date de leur première mise en circulation ; 2° Postérieurement à ce contrôle, d’un contrôle technique périodique, renouvelé tous les deux ans” (Article R323-22 of the Code de la route). ANTS accepts a French test or a foreign test less than six months old where applicable, so a recent British MOT certificate can bridge the gap for a freshly imported car, but plan a French test promptly because test centres examine headlamp aim, emissions and the VIN plate with particular care on right-hand-drive cars. Keep the insurance certificate current throughout, since Article R322-1 of the Code de la route makes cover a condition of registration and Article L324-2 punishes its absence.
While the file is examined, the law lets you drive under a provisional registration certificate, the certificat provisoire d’immatriculation, commonly called the CPI, which ANTS issues once the core documents check out. The text provides that “la circulation d’un véhicule est autorisée sous couvert d’un certificat provisoire d’immatriculation” (Article R322-3 of the Code de la route). Treat the CPI as fragile: it lasts about a month, it must be carried with the insurance certificate, and if it expires before the final carte grise arrives the car must stop moving. A recent appeal decision shows what happens when paperwork stalls. A buyer left with only an expired provisional certificate saw his car seized off the road: “Le 25 avril 2023, le véhicule a fait l’objet d’une immobilisation administrative en raison de la péremption du certificat provisoire d’immatriculation” (Court of Appeal of Douai, 24 April 2025, RG 24/00057, official full text). Never let a CPI lapse assuming the final document will catch up on its own.
Plates and costs close the procedure. French plates follow the SIV system, the national registration series, with the number assigned for the life of the vehicle. The display rules are exact: “Tout véhicule à moteur, à l’exception des matériels de travaux publics doit être muni de deux plaques d’immatriculation, portant le numéro assigné au véhicule et fixées en évidence d’une manière inamovible à l’avant et à l’arrière du véhicule” (Article R317-8 of the Code de la route). Order them only after the final number is issued, fix them immovably, and remove the UK plates from circulation use. The registration tax itself combines a regional horsepower tax, the taxe régionale per cheval fiscal, which varies by region and by the car’s rated power, with a flat handling fee and, for high-emission vehicles, the malus sur les véhicules polluants. Simulate the total on the official ANTS calculator before paying, because a powerful second-hand Range Rover can cost several hundred euros to register while a small hybrid costs far less, and the payment is by bank card only.
B. What Can You Do When ANTS Rejects Your File, and What Are the Penalties for Driving on Invalid Papers?
A refusal is rarely the end of the road; it is usually a diagnosis. The most frequent grounds in British files are a missing or unreadable 846A, a certificate of conformity that does not cover the exact variant, a proof of address older than six months, a VIN that does not match across documents, or an unpaid customs balance. When the status reads “à compléter”, reply inside the portal quickly with the missing page in a clean scan, because silence lets the file slide toward rejection. When it reads “demande rejetée”, read the stated reasons line by line, fix each one at source, customs office, manufacturer or insurer, and lodge a fresh, complete application rather than re-uploading the same defective pages. If the refusal looks legally wrong, for example customs clearance granted but registration denied on a ground the codes do not support, write a reasoned informal appeal, the recours gracieux, to the prefectural registration service, then an appeal to the Minister of the Interior, and finally an action before the administrative court, the tribunal administratif, within two months of the express refusal. Keep every receipt, every portal screenshot and every letter, because limitation periods run from notification and a judge decides on papers.
When the blockage comes from a seller or an intermediary rather than the state, the courts order delivery of the missing document under financial pressure. In the Douai case, the buyer of a second-hand car had waited months for his final registration while the dealer stalled, and the court of appeal “Condamne la société EB Auto à fournir à M. [N] [E], entrepreneur individuel exerçant sous la dénomination EIRL [E] [N], le certificat définitif d’immatriculation du véhicule de marque Peugeot, modèle Partner”, adding that “ladite société devra s’acquitter de cette obligation dans les deux mois de la signification du présent arrêt, sous astreinte définitive de 100 euros par jour de retard pendant une durée de deux mois” (Court of Appeal of Douai, 24 April 2025, RG 24/00057, official full text). The astreinte, the daily penalty payment for delay, plus a 1,438.68 euro provision for the loss caused by the immobilisation, shows the method: a formal demand letter first, then summary proceedings, the référé, before the judicial court to obtain the document under penalty. British buyers who purchase from French dealers should use the same sequence and never accept vague promises once the CPI nears expiry.
Driving on while the papers are wrong carries its own ladder of sanctions, and registration changes who pays. Once the carte grise exists, criminal liability for driving offences stays with the driver, but the financial burden shifts to the registered keeper. The Court of Cassation restated the split recently: “Selon le premier de ces textes, le conducteur d’un véhicule est responsable pénalement des infractions commises par lui dans la conduite dudit véhicule”, while “Par dérogation à ce texte, le second prévoit que le titulaire du certificat d’immatriculation du véhicule est redevable pécuniairement de l’amende encourue pour les contraventions aux règles sur le sens de la circulation, à moins qu’il n’établisse l’existence d’un vol ou de tout autre événement de force majeure ou qu’il n’apporte tous éléments permettant d’établir qu’il n’est pas l’auteur véritable de l’infraction” (Court of Cassation, criminal chamber, 18 November 2025, No. 25-83.480, official full text). In plain terms, register the car in your own name the day you can, lend it only to insured drivers, and keep proof of any theft or sale, because fines follow the keeper shown on the certificate. Add the insurance offence at 3,750 euros, the immobilisation that follows an expired CPI, and the customs penalties for an undeclared import, and the cheapest strategy is obvious: clear customs in week one, file ANTS in week two, and chase every “à compléter” within days.
The tax side does not end at the customs counter either. Import VAT and the transfer-of-residence franchise decide the entry cost, but using the car in France raises residence and reporting questions that belong to the wider settlement: where you are tax resident, how your British income is declared, and which treaty article shields your pension or your rental income. Readers sorting the whole move should study our companion analysis of the Franco-British double tax treaty alongside this guide (British-French double tax treaty: residence, tie-breaker and relief), because customs residence and tax residence are cousins, not twins, and the treaty answers the questions the 846A does not ask.
Conclusion
Bringing a British car to France after Brexit is a three-gate course, and the gates must be taken in order. First, close the British file properly with the DVLA permanent-export declaration and keep the V5C, because every French counter will ask for it. Second, pass French customs, pay the 20 percent import VAT and any duty, or prove the transfer-of-residence franchise with your duplicate inventory and six months of ownership, and leave with the 846A clearance certificate that alone opens the registration door. Third, lodge a complete ANTS file inside the one-month window with conformity, roadworthiness, insurance and fresh proof of address, drive only under a valid provisional certificate while waiting, and answer every request for supplements within days. Refusals yield to method: corrected papers, reasoned appeals up to the administrative court, and court-ordered delivery under daily penalties when a seller withholds the document. Take the timetable seriously from the ferry ramp, and your UK car becomes a French car without drama, fines or impound lots.
