You have found the flat: a two-bedroom appartement in the 11th arrondissement of Paris, or a stone house outside Bordeaux for the school year. The letting agent slides the lease across the desk, names a rent that makes your eyes water, and asks for a month’s rent as a dépôt de garantie (security deposit) before you get the keys. Since Brexit turned British citizens into third-country nationals in France, renting here feels like an obstacle course designed for someone else: French leases run to pages of dense clauses, Paris caps rents by statute in a way no English city does, and when you leave, landlords too often treat the deposit as a parting gift to themselves. This guide explains the two moments when British tenants lose the most money — signing, and leaving — and the exact legal levers that get money back. Every French term is explained the first time it appears, and every decisive rule is linked to its official text so you can check it yourself. Part I covers the rent you agree on the day you sign: the Paris rent cap, the lawful complément de loyer (rent supplement), and the deposit and energy-rating checks that belong in every file. Part II covers the exit: notice periods, the check-in/check-out inventory battle, the one-month and two-month refund deadlines, the 10 per cent monthly penalty for late return, and the judge who decides these disputes.

I. Is the Rent You Are Asked to Sign Lawful, and Is the Deposit Demand Legal?

Two questions decide whether your tenancy starts on sound footing: does the rent respect the cap that applies in Paris and other controlled cities, and has the landlord demanded no more money up front than the statute allows? Both answers come from the same statute, loi n° 89-462 du 6 juillet 1989 (the Act of 6 July 1989 improving rental relations), which governs nearly every residential lease with the dwelling as the tenant’s résidence principale (main home). Get these two points right on signing day and most later disputes never happen.

A. Paris rent caps: the reference rent, the increased reference rent and the supplement tenants actually pay

If your flat is in Paris, the landlord does not set the rent freely. Since July 2019 Paris has applied the encadrement des loyers (rent cap): each lease must state the loyer de référence (reference rent) and the loyer de référence majoré (increased reference rent) for the dwelling’s category, which depend on location, number of rooms, furnished or unfurnished letting, and construction period, and the loyer de base (basic rent, excluding charges and excluding any supplement) may not exceed the increased reference rent. The official explanation, kept current by the Prime Minister’s legal information service, sets out the mechanism, the simulators that compute your street’s reference rents, and the sanctions: a landlord who ignores the cap faces an administrative fine of up to 5,000 euros, or 15,000 euros where the landlord is a company (service-public.fr, rent control in tense areas). The same cap covers parts of the inner suburbs — the Est Ensemble and Plaine Commune territories — and cities including Lyon, Villeurbanne, Bordeaux, Montpellier and Lille, so check the list even outside the capital.

Three reflexes protect you before you sign. First, run your address through the City of Paris tester (Paris: test my rent) and compare the proposed basic rent with the increased reference rent for your category. Second, read the lease for the two mandatory figures: where the lease omits the increased reference rent, you have one month from the lease’s effective date to put the landlord on notice by lettre recommandée avec accusé de réception (registered letter with acknowledgement of receipt, universally shortened to LRAR) to add it, the landlord then has one month to reply, and without a satisfactory reply you have three months to ask the juge des contentieux de la protection (the protection-litigation judge, the dedicated housing judge) to cut the rent. Third, where the basic rent itself exceeds the increased reference rent, act in the statutory order: apply first to the commission départementale de conciliation (departmental conciliation commission, the free local mediation body for rental disputes, known as the CDC) (service-public.fr, conciliation commission), then to the protection-litigation judge for a rent reduction and repayment of the overpaid sums, and report the breach to the City of Paris, which can fine the landlord. Note that court action has a compulsory first step: “à peine d’irrecevabilité que le juge peut prononcer d’office, la demande en justice est précédée, au choix des parties, d’une tentative de conciliation menée par un conciliateur de justice, d’une tentative de médiation ou d’une tentative de procédure participative, lorsqu’elle tend au paiement d’une somme n’excédant pas 5 000 euros” — claims for up to 5,000 euros must first go through conciliation, mediation or a participatory procedure, failing which the judge may declare them inadmissible (Code of Civil Procedure, Article 750-1). The free conciliation commission therefore doubles as your mandatory gateway to the courts.

The lawful exception landlords rely on is the complément de loyer (rent supplement): an extra amount above the increased reference rent, allowed only where the dwelling offers location or comfort characteristics that are exceptional by comparison with dwellings of the same category in the same area, and that genuinely determined the rent. The Cour de cassation, France’s supreme court for civil matters, policed that boundary in a Paris dispute decided on 4 December 2025. The case concerned a sixteen-square-metre studio where a supplement of 120 euros sat on top of a basic rent of 440 euros; the tenant sought cancellation of the supplement and repayment. The Third Civil Chamber rejected the appeal and approved the lower courts’ reasoning in these terms: “Ayant relevé que le logement était lumineux et calme, caractéristiques rares et particulièrement recherchées à [Localité 3], provenant non pas de la situation géographique ayant donné lieu à la fixation du loyer de référence mais de l’étage élevé du logement, et que l’immeuble étant, en outre, doté d’un ascenseur, cet équipement n’étant considéré qu’en tant qu’il permet de bénéficier des avantages d’un étage élevé sans en souffrir les inconvénients, la cour d’appel, qui a procédé aux recherches prétendument omises, a pu en déduire que le complément de loyer était fondé et a, par ces seuls motifs, légalement justifié sa décision.” In plain terms: brightness and quiet, rare and much sought after in that city, flowing from a high floor rather than from the neighbourhood itself, can justify a supplement, and a lift counts only as the equipment that lets the tenant enjoy a high floor without its drawbacks (Cass., 3rd Civil Chamber, 4 December 2025, No 24-17.930).

The lesson for a British tenant is practical, not abstract. A supplement of “calm and light” in an ordinary second-floor flat on a busy boulevard is contestable; the same words for a top-floor flat with a lift survived supreme-court review. Ask the agent to write the supplement’s justification into the lease with concrete facts — floor, exposure, view, terrace, exceptional fittings — and keep the listing, because the advertisement must carry the same figures. A vague supplement with no factual anchor is the easiest kind to challenge before the conciliation commission.

One more rent rule catches British newcomers by surprise: the energy freeze. For leases signed, renewed or tacitly renewed since 24 August 2022 in metropolitan France, the rent of a dwelling rated F or G on the diagnostic de performance énergétique (energy performance certificate, the DPE) may not be increased at all — no annual indexation, no uplift. Before agreeing any rent, read the DPE, and treat an F or G rating as both a comfort warning and a legal ceiling on the landlord’s future demands.

B. Money on signing day: the one-month deposit, the inventory that decides everything later, and the energy ban

French law caps what the landlord can take before handing over the keys. For an unfurnished dwelling let as a main home, where the rent is payable monthly in advance, the dépôt de garantie may not exceed one month’s rent excluding charges (charges being the service charges for the building, such as cleaning, lift maintenance and caretaking); it must be stated in the lease and may never be increased during the lease or on renewal. Where the rent is payable two months in advance the ceiling is the same one month, and where the rent is payable quarterly in advance no deposit may be demanded at all (service-public.fr, security deposit in a residential lease). For furnished lettings the ceiling is two months’ rent. Any demand above those ceilings is unlawful, however the lease clause is drafted, and any sum beyond rent, deposit and lawful agency fees demanded as the price of signing is prohibited.

The document that will decide your deposit dispute two or three years from now is signed on moving-in day: the état des lieux (inventory of condition), drawn up jointly at entry and again at exit, describing every room, fitting and surface. Photograph everything, note every stain, crack, drip and worn seal in writing on the form itself, and keep a copy: the comparison between the two inventories is the legal measure of what changed during your occupation. The Civil Code states the default rule bluntly: “S’il n’a pas été fait d’état des lieux, le preneur est présumé les avoir reçus en bon état de réparations locatives, et doit les rendre tels, sauf la preuve contraire.” — where no inventory was drawn up, the tenant is presumed to have received the dwelling in good decorative repair and must return it so, unless proof to the contrary (Civil Code, Article 1731). And during the tenancy the tenant answers for deterioration: “Il répond des dégradations ou des pertes qui arrivent pendant sa jouissance, à moins qu’il ne prouve qu’elles ont eu lieu sans sa faute.” — the tenant is liable for damage occurring during occupation unless proof it happened through no fault of theirs (Civil Code, Article 1732). Where the landlord refuses an entry inventory, send a formal demand at once; the inventory may also be drawn up by a commissaire de justice (the judicial officer, formerly huissier de justice), whose report carries real weight later. The underlying logic is the Civil Code’s rule on proof: “Celui qui réclame l’exécution d’une obligation doit la prouver. Réciproquement, celui qui se prétend libéré doit justifier le paiement ou le fait qui a produit l’extinction de son obligation.” — whoever demands performance must prove the obligation, and whoever claims to be discharged must prove payment or extinction (Civil Code, Article 1353). In a deposit fight the landlord claiming damage proves it; the tenant claiming repayment proves the lease, the payment and the key return.

British tenants should also check the energy rating before signing anything, because the worst ratings now block lettings entirely. Since 1 January 2025, dwellings rated G on the DPE are deemed indecent and may not be let under contracts signed, renewed or tacitly renewed from that date; the ban extends to F-rated dwellings on 1 January 2028 and to E-rated dwellings in 2034, under the loi climat et résilience (climate and resilience Act) of 22 August 2021 (service-public.fr, thermal sieves banned from letting). A landlord offering you a G-rated flat on a fresh lease in 2026 is offering something the statute forbids; the tenant’s remedies for indecent dwellings include formal notice to the landlord and, failing action, proceedings to compel works. Ask for the DPE with the listing, not on moving day.

A final signing-day point for British arrivals: your immigration status does not change these rules — the 1989 Act protects every tenant whose dwelling is their main home — but it changes your paperwork. Landlords and agents routinely ask for proof of identity, income and previous landlord references, and British passports now sit in the “other nationalities” pile. The British government’s own country guide remains the starting point for the residence side of the move (GOV.UK, Living in France), while a companion guide on this site explains the landlord’s tax side of the same tenancies, which helps you understand what your rent funds (British landlord in France: furnished-rental tax guide). Keep your residence permit, employment contract or pension statements and UK bank references in one file; a complete dossier de location (rental application file) shortens every negotiation.

II. Leaving and Getting Your Money Back: Notice, Inventories and the Deposit Deadlines

Most British tenants discover French rental law when they leave: the notice letter comes back with a warning, the exit inventory lists “damage” nobody mentioned, and the deposit trickles back months late with unexplained deductions. The statute answers each of these points with a deadline, and missing a deadline costs the party that missed it. This part walks through the exit in order: giving notice correctly, surviving the inventory comparison, then recovering the deposit with interest-like penalties where the landlord drags their feet.

A. Giving notice that works and surviving the exit inventory

The tenant may end the lease at any time: no reason is required, only proper form and the notice period (préavis). Notice must be served by registered letter with acknowledgement of receipt, by a judicial officer’s writ (signification), or handed to the landlord against a signed receipt; an electronic registered letter is equally valid. The standard period is three months, but it falls to one month in the cases that matter most to mobile British tenants: dwellings in a zone tendue (tense area, the high-demand municipalities listed by decree, which include Paris and much of the inner suburbs), professional relocation, a first job, a new job after unemployment, or health reasons. In a tense area the one-month period applies only if your letter states the flat’s address and expressly invokes the one-month period under Article 15 of the 1989 Act and the decree on tense areas — omit that sentence and the period stays three months (service-public.fr, tenant notice periods). Rent remains due through the notice period, and you must allow viewings in the final weeks within the lease’s agreed limits.

On departure day, the exit inventory is compared line by line with the entry inventory, and only differences count. Usure normale (fair wear and tear) — faded paint after six years, a worn carpet path, small nail holes filled and made good — is the landlord’s cost of doing business, while burns, broken tiles, unfilled holes, Simplified: damage beyond normal ageing, and cleaning left undone can be charged. Because the entry inventory is the baseline, vague entry descriptions (“good condition” for every room) become weapons at exit: insist on detail at entry, in words and dated photographs, and attend the exit inspection personally with your copy. Where the landlord claims professional cleaning or full redecoration, ask for the comparative passage in both inventories plus an invoice or estimate — a demand supported by neither fails at conciliation.

Charges (charges locatives) deserve a separate check before you sign the final account. During the tenancy you pay a monthly provision with an annual reckoning (régularisation) against the building’s actual bills. At exit in a block of flats (copropriété, the French condominium regime), the landlord may hold back a capped provision from the deposit until the building’s yearly accounts are finally approved — no more than 20 per cent of the deposit, calculated on evidence — and must settle the final balance within one month after that approval. Agreeing an immediate full settlement on the spot is allowed where both sides prefer a clean break, and for short, simple tenancies it is usually the sensible option.

B. Recovering the deposit: the one-month and two-month deadlines, the 10 per cent penalty, and the judge who decides

The refund clock starts the day you return the keys, by hand against receipt or by registered letter, and the deadline depends on the inventories: one month maximum where the exit inventory matches the entry inventory, two months maximum where it does not. The landlord must return the new contact details you left — new address and bank details (RIB, the bank identity statement) — and may deduct only evidenced sums: unpaid rent or charges, damage established by comparing the two inventories with photographs, a judicial officer’s report, invoices or works estimates, or an unanswered formal demand for arrears. Every deduction must be documented and sent to you; a bare line reading “repairs: 800 euros” with no invoice, no estimate and no inventory reference is not a justification and will not survive a challenge (service-public.fr, deposit return rules). Where the flat was sold mid-lease, the new owner owes the refund; where the managing agent changed, the new agent owes it.

Late return is expensive for the landlord by design: the refund is increased by 10 per cent of the monthly rent excluding charges for each month of delay started. On a rent of 1,400 euros excluding charges, returning the deposit two months and a day late adds 280 euros to what you are owed, automatically, without proving any loss. That penalty runs on the deposit proper; the Cour de cassation drew the boundary precisely in a 2018 ruling on Article 22 of the 1989 Act. The Court recalled that “le dépôt de garantie est prévu pour garantir l’exécution de ses obligations locatives par le locataire” — the deposit exists to secure the tenant’s performance — and that in collective buildings “la régularisation définitive des charges et la restitution du solde, déduction faite, le cas échéant, des sommes restant dues au bailleur et de celles dont celui-ci pourrait être tenu en lieu et place du locataire, interviennent dans le mois qui suit l’approbation définitive des comptes de l’immeuble” — the final charge settlement and the return of the balance come within the month after the building’s accounts are finally approved. The lower court had applied the 10 per cent penalty to a balance that actually came from the charge settlement, which follows its own timetable; having found that the repair sums exceeded the deposit and that the landlord’s debt arose from the settlement, the court could not lawfully add the late-deposit penalty, and the judgment was quashed (Cass., 3rd Civil Chamber, 31 May 2018, No 17-18.069). For tenants the message cuts both ways: claim the penalty firmly where the deposit itself is late, but expect the landlord’s lawyer to invoke this ruling where the argument is really about charges.

The enforcement path is graduated and costs little. Start with a registered formal demand (mise en demeure) recalculating the deadline, listing each deduction you dispute and the proof you require, and setting a short payment date. Failing payment, file with the departmental conciliation commission, which hears landlord-tenant deposit and rent disputes free of charge and often settles them. Failing conciliation, that judge decides: “Le juge des contentieux de la protection connaît des actions dont un contrat de louage d’immeubles à usage d’habitation ou un contrat portant sur l’occupation d’un logement est l’objet, la cause ou l’occasion” — the protection-litigation judge hears claims arising from residential leases (Code of Judicial Organisation, Article L213-4-4). Bring both inventories with your photographs, the lease, the rent receipts (quittances de loyer), the key-return proof, every letter exchanged, and a dated calculation of the penalty. Deposit claims are document cases: the side with the complete, dated file almost always wins. And losing costs more than the deposit itself, because “Le juge condamne la partie tenue aux dépens ou qui perd son procès à payer” the other side’s recoverable costs — the judge orders the losing party to pay costs (Code of Civil Procedure, Article 700), which is why landlords so often settle once a complete file lands on the conciliator’s desk.

Conclusion

Renting in France as a British tenant after Brexit means living under a statute that, for once, favours the careful: capped rents in Paris and the other controlled cities, a deposit strictly limited at signing, a one-month or two-month refund clock at exit, and a 10 per cent monthly penalty where the landlord keeps your money too long. The tenants who recover their deposits in full share three habits: they test the rent against the reference figures before signing, they build a detailed entry inventory with photographs on moving day, and they give notice in the form the statute requires with the one-month wording where it applies. The Cour de cassation’s recent rulings show judges applying these texts exactly as written — upholding a documented rent supplement in December 2025, striking down a misapplied late penalty in 2018 — so frame every demand in the statute’s own terms, keep every receipt, and escalate through conciliation to the protection-litigation judge where the landlord will not pay. Your deposit is a guarantee for your obligations, not a gratuity for the landlord, and French law treats it that way.
