Tesco Marketplace on Mirakl
Tesco Marketplace puts other businesses’ products in front of shoppers on what Tesco calls “the UK’s largest grocery platform”5. Tesco counts it among its “emerging digital businesses”, alongside F&F Online2.
In October 2025, Tesco moved the marketplace to Mirakl, “to improve seller onboarding process and enhance the customer proposition”2. Over its 2025/26 financial year, average weekly traffic more than doubled, average basket spend grew by about 90% and the range passed 450,000 SKUs2.
Tesco’s interim results of 7 October 2026 report “Over 1,000 sellers now on Tesco Marketplace, up over 80% year-on-year”3. In January 2025, before the move, Grocery Gazette reported over 250 sellers and over 300,000 SKUs6. The categories then ran from baby, toys and beauty to garden, DIY and pet care6.
What Tesco looks for in sellers
Tesco’s seller FAQ sums up its approach: “Quality, trust and reliable customer service matter to us, and we work with sellers who share these values”7.
Neither that FAQ nor the application page lists eligibility rules, such as company or VAT registration, or where your business must be based75. Clarify these with Tesco before you commit, especially if you are based outside the UK.
In practice, you deliver every order and deal with return requests yourself, as Tesco’s delivery and returns rules below show14.

Delivery and Tesco’s return promise
Tesco tells customers that “All Tesco Marketplace products are delivered directly from our sellers”, by post or courier1. You choose your own delivery method and fulfilment partner1.
Marketplace items arrive separately from Tesco groceries and do not come with Click+Collect, Home Delivery or Whoosh grocery orders1. Tesco also notes that “Big heavy products need specialist delivery”1. You email customers delivery updates, and they can track orders in their Tesco account or app1.
Tesco’s “Marketplace return promise” gives customers these terms4:
- Change of mind: the customer contacts you within 30 days, and you reply with the next steps4.
- Faults: an item can be reported faulty within 12 months of delivery, and Tesco guarantees a full refund, repair or replacement within the first 6 months4.
- Delivery charges: standard delivery is usually refunded if the item is returned within 14 days of purchase; for express delivery, only the standard charge is refunded4.
- Exclusions: perishable, live, chilled or frozen items, personalised items, and hygiene-sealed items unless unopened with seals intact; clothing must be unworn, with tags4.
- Disputes: if you refuse a return, the customer can contact Tesco, and then an alternative dispute resolution provider such as Consumer Arbitration4.
The promise does not say who pays return postage after a change of mind4. Ask Tesco how this works for your products.
