Leroy Merlin is the largest DIY and home-improvement retailer in continental Europe, owned by the Adeo group (Mulliez family). Its marketplace — running on Mirakl in France, Spain and Italy — has become a serious third channel for brands in tools, building materials, garden, smart home, bathroom, kitchen and outdoor living. It is not a generalist marketplace and it is not Amazon. The traffic is intent-driven, the catalogue is curated, and approval is gated. This guide explains how the 2026 onboarding actually works across the three live markets, what compliance you carry as a seller, and where the typical traps sit.
What Leroy Merlin Marketplace actually is
Leroy Merlin Marketplace is a third-party seller layer sitting on top of the Leroy Merlin retail site in each country. Customers shop a single catalogue; products are either sold by Leroy Merlin itself (1P) or by an approved external seller (3P). Orders, returns and customer messaging are routed through the Mirakl seller back-office. The marketplace runs as a separate legal flow per country — leroymerlin.fr, leroymerlin.es and leroymerlin.it each have their own contract, their own EPR registrations, their own payout entity and their own catalogue rules. There is no single "EU account" the way Amazon offers one.
The proposition for a brand is straightforward: you reach a buyer who is already in the DIY mindset, who trusts the Leroy Merlin brand, and who is often spending on basket sizes that do not exist on a generalist site (a €600 garden shed, a €1,200 fitted kitchen module, a €300 power-tool kit). The trade-off is curation: Leroy Merlin only opens categories it wants to deepen, and only to sellers it has vetted.
Category fit: what gets approved, what does not
The marketplace is anchored in home improvement and outdoor living. In practical terms, the categories that consistently get through onboarding in 2026 are:
- Power tools, hand tools, workshop equipment and accessories
- Building materials, fixings, plumbing, electrical components
- Garden — furniture, BBQs, sheds, irrigation, power garden tools, plants in some markets
- Bathroom and kitchen — furniture, fittings, taps, sinks, storage
- Smart home, lighting, heating and cooling
- Decoration, paint, flooring and tiling adjacencies
- Pet supplies and outdoor leisure in selected sub-categories
Categories that are typically refused or heavily restricted: fashion and apparel, food and groceries, raw consumer electronics outside the home-improvement context (phones, laptops, gaming), toys outside outdoor play, and anything regulated as a medical device. Chemicals, batteries above certain energy thresholds, pressurised gas, paint above flash-point limits and pesticide-classified garden products carry transport and labelling rules that often disqualify smaller sellers — not because the marketplace bans them, but because the carrier and dangerous-goods workflow is heavier than most 3P sellers can support.
The partner approval workflow
Onboarding to Leroy Merlin Marketplace is an application, not a self-signup. The path in 2026 looks like this:
- Expression of interest per country, submitted through the Leroy Merlin "Vendre sur Leroy Merlin" / "Vende en Leroy Merlin" / "Vendi su Leroy Merlin" portals. You submit company details, brand portfolio, category, expected SKU count, country of dispatch and an indicative catalogue.
- Category and assortment review, run by the local commercial team. They are looking for catalogue depth in a category they want to grow, not single-SKU sellers. A 5-SKU power-tool range will rarely clear; a 60-SKU coherent range will.
- Commercial pre-qualification call. Expect questions about price positioning against the Leroy Merlin own-brand range, expected logistics SLA, after-sales capacity, language coverage and EPR/compliance status.
- Contracting and Mirakl onboarding. You sign the local seller contract, complete the Mirakl seller record, connect a bank account in the right currency and pass KYC. Each country is a separate contract and a separate Mirakl shop.
- Catalogue integration. You upload via the Mirakl product feed, an EDI connector or one of the supported PIM/integrator routes. Leroy Merlin enforces its own attribute schema per category — generic Amazon feeds will not work without remapping.
- Test orders and go-live. The shop is opened in a controlled state, a handful of orders are processed end-to-end (including a real return), and the assortment is then released to full catalogue exposure.
End-to-end the process typically runs eight to fourteen weeks per country in 2026, and the three markets do not share a queue — France clearing does not accelerate Spain or Italy. See /merchant-of-record for how this interacts with seller-of-record routing.
Per-market language and content rules
Leroy Merlin is unusually strict on local-language content. The marketplace will not let you go live with English-only listings, and machine-translated copy is rejected at quality review more often than sellers expect.
- France — full French listings (title, description, attributes, safety information, manuals). The Toubon Law applies: any commercial information presented to a French consumer must be available in French. Customer service must be answered in French within the marketplace SLA.
- Spain — Spanish (Castilian) listings. Catalan, Galician or Basque are not required at marketplace level but are appreciated in support. Manuals and safety inserts must be in Spanish per consumer law.
- Italy — Italian listings, including the safety, warranty and CE-marking text required by the Codice del Consumo. Italian-language after-sales is mandatory.
Images, technical drawings and measurement units also need to match local convention (metric throughout, EU plug types, EU-spec voltages on electricals).
EPR: Citeo, RD 1055/2022 and CONAI
Every product placed on the market in FR, ES or IT carries Extended Producer Responsibility obligations, and the marketplace is required by law to verify that you are registered before activating you. This is the single most common reason go-lives slip.
- France — Citeo. Household packaging EPR is managed by Citeo (formerly Eco-Emballages). You need a Unique Identification Number (UIN) for the packaging stream and, depending on assortment, additional UINs for furniture (Ecomaison), DIY and garden (Ecomaison / Ecologic), electricals (Ecosystem / Ecologic), batteries (Corepile / Screlec) and tyres. Leroy Merlin will request the UIN per stream during onboarding and again at any category extension. See /compliance-glossary for the full UIN map.
- Spain — Real Decreto 1055/2022. Since 2023 Spain treats packaging EPR much closer to the French model. You register with a SCRAP (typically Ecoembes for household packaging, Ecoembes-managed schemes for commercial) and report tonnage. Leroy Merlin Spain validates the producer registry number before activation.
- Italy — CONAI. The Consorzio Nazionale Imballaggi is the umbrella scheme; you register and pay the Contributo Ambientale CONAI per material stream (paper, plastic, glass, wood, metal, aluminium). WEEE is handled separately under D.Lgs. 49/2014 through a registered consortium. The marketplace asks for the CONAI registration number.
For non-EU brands, all three markets also require an authorised representative for WEEE, batteries and, increasingly, packaging. This cannot be the marketplace and cannot be a freight forwarder.
GPSR — the new baseline since December 2024
The EU General Product Safety Regulation (EU 2023/988) applies to all three markets and is enforced rigorously by Leroy Merlin. For every product you list you must show:
- A responsible economic operator established in the EU — manufacturer, authorised representative, importer or fulfilment service provider — with name, postal address and contact email on the listing and on the product or packaging.
- Traceability information (batch or model identifier) on the product.
- Safety warnings and instructions in the language of each market the product is sold in.
- Technical documentation available on request and a corrective-action procedure ready to execute.
Listings without a valid EU responsible person are taken down automatically. Non-EU sellers without an EU establishment route this through an authorised representative or through a merchant-of-record partner.
Logistics, returns and SLA
Leroy Merlin runs on a seller-fulfilled model in 2026 across the three markets — there is no equivalent of FBA. You ship from your own warehouse (or your 3PL) to the customer, with carrier of your choice but subject to SLA: acceptance within one working day, dispatch within two, tracking on every order, and full returns acceptance per the local distance-selling regime (14 days in all three markets, sometimes extended by Leroy Merlin to 30 or 100 days for specific categories). Bulky items follow a separate, longer SLA and require a confirmed delivery slot with the customer.
Where Operator One fits
Operator One is a merchant-of-record operator for European marketplaces — founded in 2023, headquartered in Almere (Netherlands) with a Lucca hub in Italy (KvK 90562704), running MoR-as-a-service since 2021 across 27 EU countries plus the UK and 100+ marketplaces including Leroy Merlin FR, ES and IT. We handle the seller-of-record contract, local EPR registrations, GPSR responsible-person duties, Mirakl onboarding, localised catalogue work and the per-country VAT and reporting layer so the brand keeps owning the product, the price and the customer relationship.
