Key Takeaways
- From 12 August 2025, online marketplaces are classified as WEEE producers for electrical and electronic equipment sold through their platforms by non-UK sellers.
- UK-based sellers remain responsible for their own WEEE producer obligations — the marketplace obligation only covers overseas sellers.
- Major platforms including Amazon, eBay, Temu, and Wish are affected, along with any online marketplace facilitating third-party EEE sales into the UK.
- This mirrors the packaging EPR marketplace obligations, creating a consistent regulatory approach across both waste streams.
What Changed in August 2025
The amended Waste Electrical and Electronic Equipment Regulations introduced a new category of obligated party: the online marketplace. From 12 August 2025, any online marketplace that facilitates the sale of electrical and electronic equipment (EEE) to UK consumers by sellers who are not established in the United Kingdom is deemed to be the “producer” of that EEE for the purposes of WEEE compliance.
This is a fundamental shift. Previously, the WEEE producer obligation sat with the business that manufactured, branded, or imported the product. For goods sold by overseas sellers through platforms like Amazon Marketplace, eBay, or Temu, the legal obligation fell on the overseas seller — a business often based in China or another country with no UK presence, no UK registration, and no practical way for UK regulators to enforce compliance.
The result was a significant compliance gap. Millions of units of EEE entered the UK market each year with no producer registered against them and no contribution to the cost of collecting and recycling those products at end of life. UK-based producers and importers — who were complying with the law — effectively subsidised the free-riding of non-UK marketplace sellers.
The August 2025 amendment closes this gap by placing the obligation on the entity that does have a UK presence and can be regulated: the marketplace platform itself.
Which Marketplaces Are Affected?
The regulations define an “online marketplace” broadly. It covers any digital platform that allows third-party sellers to offer goods for sale to UK consumers. The key criterion is that the marketplace facilitates the transaction — it provides the platform, processes payments, or otherwise enables the sale — rather than simply advertising products.
The major platforms affected include:
- Amazon (Marketplace third-party sales, not Amazon’s own retail operations)
- eBay (third-party seller listings for new EEE)
- Temu (the vast majority of sellers are based outside the UK)
- Wish (similarly dominated by non-UK sellers)
- AliExpress (Alibaba’s consumer-facing marketplace)
- Etsy (for sellers offering handmade or vintage electronics, or electronics components)
- OnBuy, Fruugo, and other smaller marketplaces facilitating cross-border EEE sales
The obligation applies only to EEE sold by non-UK sellers through the marketplace. If a UK-based seller uses Amazon Marketplace to sell electronics, the marketplace is not the producer for those sales — the UK seller retains their own producer obligations.
What About Fulfilment Services?
The regulations distinguish between marketplace services and fulfilment services. A business that only provides warehousing, packing, and shipping (such as a third-party logistics provider) is not a marketplace. However, Amazon’s FBA (Fulfilment by Amazon) service is part of the broader Amazon Marketplace ecosystem, and goods sold through FBA by non-UK sellers do fall within the marketplace’s WEEE obligation.
What This Means for Third-Party Sellers
The impact on third-party sellers depends on where they are established.
Non-UK Sellers
If you are a seller based outside the UK and you sell EEE through an online marketplace to UK consumers, the marketplace is now the WEEE producer for your products. In practical terms:
- You no longer need to individually register as a WEEE producer in the UK for sales made through the marketplace (though you remain responsible for any direct sales outside the marketplace)
- The marketplace will fund the collection and recycling of your products at end of life through its own PCS membership
- The marketplace may pass costs on to you through higher commission rates, per-unit environmental levies, or other fee structures — this is a commercial decision for each platform
- You must still comply with product marking requirements — your EEE must carry the crossed-out wheelie bin WEEE symbol regardless of who holds the producer obligation
The key nuance: this only covers sales through the marketplace. If you also sell directly to UK consumers via your own website, you still need your own UK WEEE producer registration for those direct sales.
UK-Based Sellers
If you are a UK-based business selling EEE through an online marketplace, the new rules do not change your obligations. You remain the WEEE producer for the products you place on the UK market, whether you sell through a marketplace, your own website, or a physical shop.
You must still:
- Register with a Producer Compliance Scheme
- Report the weight of EEE you place on the UK market quarterly
- Pay your PCS membership fees to fund collection and recycling
- Ensure your products carry the correct WEEE markings
The marketplace obligation exists specifically to catch non-UK sellers who cannot be effectively regulated directly. UK sellers have always been within regulatory reach and remain fully responsible.
Implications for UK-Based Marketplace Sellers
While the new rules do not change your legal obligations as a UK seller, they have indirect implications worth understanding.
Levelling the Playing Field
Before August 2025, non-UK marketplace sellers had a cost advantage: they were not paying into the WEEE system while their UK competitors were. The marketplace obligation eliminates this advantage. The costs the marketplace incurs for non-UK seller compliance will likely be reflected in the fees those sellers pay to the platform, bringing their cost base closer to that of compliant UK sellers.
Potential for Marketplace Fee Changes
Marketplaces will incur substantial costs from their new WEEE producer obligations. These costs will be distributed somehow — through general commission increases, per-category surcharges, or other mechanisms. UK sellers may see indirect effects if marketplaces adjust their overall fee structures, though the primary cost burden should fall on the non-UK seller segment that triggered the obligation.
Competitive Dynamics
The new rules may reduce the volume of EEE offered by non-UK sellers on UK marketplaces, particularly low-value items where the added compliance cost per unit makes the product uneconomic. This could create opportunities for UK-based sellers in categories where they compete directly with overseas suppliers.
Data and Reporting
Marketplaces may request additional product data from all sellers — including UK sellers — to improve their ability to identify which products are EEE and to accurately report placed-on-market weights. Be prepared to provide detailed product specifications, weights, and category classifications if your marketplace requests them.
Practical Steps for Marketplace Operators
If you operate an online marketplace that facilitates the sale of EEE to UK consumers, here is what you need to have in place.
Register as a WEEE Producer
You must join an approved Producer Compliance Scheme and register as a WEEE producer. The deadline for marketplace PCS registration was 15 November 2025. Your registration should cover all 15 WEEE categories unless you can demonstrate that certain categories are never sold through your platform.
Identify Non-UK Sellers
Build systems to accurately identify which of your sellers are established in the UK and which are not. The WEEE obligation only applies to non-UK seller transactions. Getting this classification wrong — either way — creates compliance risk.
Track EEE Sales by Non-UK Sellers
You need robust data on the weight and category of EEE sold by non-UK sellers through your platform. This data feeds into your quarterly WEEE reports. For marketplaces with millions of product listings, this requires automated product classification systems.
Report Quarterly to Your PCS
Submit quarterly data on the weight of EEE placed on the UK market through non-UK seller sales, broken down by the 15 WEEE categories. Accuracy is essential — underreporting leads to enforcement risk, while overreporting inflates your PCS fees unnecessarily.
Communicate With Sellers
Inform your non-UK sellers that the marketplace now holds the WEEE producer obligation for their sales. Communicate any changes to fee structures or data requirements. Make clear that sellers remain responsible for product marking (the WEEE symbol) and for any direct sales outside the marketplace.
Budget for Compliance Costs
PCS membership fees for a major marketplace could be substantial, given the volume of EEE flowing through the platform from non-UK sellers. Model these costs carefully and determine how they will be funded — through seller fees, general revenue, or a combination.
How This Interacts With Packaging EPR
The online marketplace WEEE obligation closely mirrors the marketplace obligations under packaging EPR. Under the reformed packaging EPR scheme, online marketplaces are similarly treated as the obligated producer for packaging on goods sold by non-UK sellers through their platform.
This creates a consistent regulatory pattern: for both WEEE and packaging, the marketplace takes on the producer responsibility that would otherwise fall on an unregulatable overseas seller.
For marketplace operators, this means:
- Combined compliance burden — you may need to register under both WEEE and packaging EPR schemes, with separate data collection and reporting for each
- Shared infrastructure — the seller identification systems you build for packaging EPR can be reused for WEEE compliance, and vice versa
- Consistent enforcement approach — regulators apply the same principle across both waste streams, reducing ambiguity about your obligations
- Holistic cost modelling — factor both WEEE and packaging EPR costs into your marketplace fee structures rather than treating them in isolation

Enforcement and Compliance Outlook
The Environment Agency has signalled that marketplace WEEE compliance will be a priority enforcement area from 2026 onwards. The initial period since August 2025 has focused on guidance, education, and voluntary compliance. From 2026, regulators are expected to move to active enforcement, including:
- Compliance audits of major marketplace operators to verify they have registered, are reporting accurately, and are funding appropriate collection volumes
- Market surveillance to identify unregistered marketplaces facilitating EEE sales
- Data cross-referencing between customs data on EEE imports and marketplace sales data to identify gaps
The penalties for non-compliance with WEEE producer obligations are severe: unlimited fines on conviction for failure to register or report, and potential criminal prosecution for providing false or misleading data. For large marketplace operators, the reputational risk of enforcement action may be as significant as the financial penalties.
Industry observers expect a period of adjustment as marketplaces refine their product classification systems and seller identification processes. Some smaller marketplaces may struggle with the compliance burden, potentially leading to consolidation in the marketplace sector or withdrawal from facilitating EEE sales by non-UK sellers.
