How to Sell on Tesco Marketplace: UK Seller Guide (2026)

What is Tesco Marketplace?

Tesco Marketplace is Tesco's third-party selling programme: approved external sellers list products on tesco.com alongside Tesco's own range, dramatically expanding the categories Tesco offers — home, garden, toys, electronics, pet, DIY and more. Customers browse and buy on Tesco's site; you fulfil the order; Tesco takes a commission.

Under the hood it runs on Mirakl, the marketplace platform used by a wave of UK retailers — B&Q, Screwfix, Currys, Superdrug and others. That matters practically: if you already sell on any Mirakl marketplace, the workflow (offers, stock feeds, order retrieval via the Mirakl seller portal or API) will feel identical, and one integration layer can serve several of them.

Why it's worth the effort

• Mainstream traffic, low seller density. Tesco's site serves one of the UK's largest retail audiences, and the marketplace is young and curated — you compete with dozens of sellers per category, not thousands as on eBay or Amazon.
• Trust transfer. Appearing on tesco.com wraps your products in one of Britain's most familiar brands. Conversion behaviour is closer to retail than marketplace bargain-hunting.
• Clubcard gravity. Tesco's loyalty ecosystem keeps shoppers inside tesco.com for more of their non-grocery spending.
• Diversification. Every pound earned off eBay/Amazon reduces your exposure to their fee and policy changes — the case we make in our multi-channel guide.

Requirements: who gets approved

Tesco curates its marketplace. Exact criteria aren't published, but successful applicants consistently have:

• A registered UK business (VAT registration expected for most)
• Marketplace track record — established sales history on other channels with strong ratings
• Reliable fulfilment — fast dispatch, tracked delivery, low defect rates
• Product liability insurance and full compliance documentation (UKCA/CE where relevant, GPSR readiness)
• Clean product data — complete attributes, barcodes (GTIN/EAN), quality images

Treat the application like a wholesale pitch, not a signup form: lead with your category strengths, fulfilment stats (dispatch time, defect rate) and existing marketplace ratings. Weak product data is a common silent rejection reason — if your catalogue lacks consistent SKUs and EAN barcodes, fix that first.

Fees and pricing

Tesco charges category-based commissionon each sale — no listing fees — with rates confirmed at onboarding, in line with other Mirakl retail marketplaces (typically in the low-to-mid teens percent range across most general-merchandise categories; confirm your category's rate directly).

Price per channel, not one-price-everywhere. Tesco's commission differs from eBay's fee stack and your Shopify processing costs, so a single blanket price either leaks margin on one channel or looks uncompetitive on another. This is exactly what per-channel price rules are for — e.g. Tesco = cost × 2.4, eBay = cost × 2.6 — applied automatically from one catalogue.

Listing: the Mirakl workflow

Once approved you get access to the Mirakl seller portal, where the model differs subtly from eBay-style marketplaces:

1. Products vs offers. Mirakl separates the product record (shared catalogue data — title, images, attributes, EAN) from your offer (your price, stock quantity, condition, delivery promise). If the product already exists in Tesco's catalogue, you attach an offer to it by EAN; if not, you submit new product data for approval.
2. Feeds or API. Small catalogues can be managed manually in the portal; anything beyond a few dozen SKUs wants automated stock/price feeds via the Mirakl API — the connection Salync maintains for you.
3. Data quality gates. Tesco reviews new product submissions. Complete attribute sets and retail-grade images pass; sparse listings bounce.

Fulfilment expectations

You fulfil from your own operation (no Tesco fulfilment service for marketplace sellers). Expectations are retail-grade:

• Dispatch within your stated handling time — typically 1–2 working days
• Tracked delivery with carrier scan events
• Returns handled to Tesco's customer standards
• Service metrics (acceptance rate, on-time dispatch, defect rate) monitored — sustained misses risk suspension

The metric that kills marketplace accounts fastest is cancellation due to no stock — which is an inventory-accuracy problem, not a fulfilment one. That brings us to the operational heart of it.

Running Tesco alongside your other channels

Adding Tesco means the same physical stock is now promised on one more storefront. Sell a unit on eBay at 2pm and your Tesco offer must know within seconds — otherwise Tesco's customer buys stock you no longer have, and you take the cancellation defect on the account you worked hardest to open.

The manual version of this (log into Mirakl, adjust quantities after every sale elsewhere) collapses beyond a handful of orders a day. The workable version is a central inventory system that treats Tesco as one more synced channel:

• One catalogue with SKUs and EANs, mapped once to your Tesco offers
• Every sale on any channel updates every other channel in real time
• Orders from Tesco flow into the same dispatch queue as eBay, Amazon and Shopify
• Low-stock alerts and reorder points computed across total demand, not per-channel silos

Salync connects to Tesco Marketplace via Mirakl alongside eBay, Amazon, Shopify, B&Q, OnBuy, Wayfair and more — full list here — with real-time sync from a single stock ledger. Free up to 50 SKUs.

Application checklist

1. UK business + VAT details ready
2. Product liability insurance certificate
3. Compliance documentation per category (UKCA/CE, GPSR)
4. Catalogue with clean SKUs, EANs, retail-grade images and full attributes
5. Fulfilment stats from existing channels (dispatch time, defect rate, ratings)
6. Apply via Tesco's marketplace seller page; expect a review period
7. On approval: connect Mirakl to your inventory system before listing, not after
