In brief: Amazon announced a package of 2026 fee changes for its European stores, including the UK, rolled out between December 2025 and February 2026. The headline is an average fee reduction of £0.15 per unit sold, driven mainly by lower FBA fulfilment fees and reduced referral fees in categories like clothing, home products and pet supplies.
But the same package includes selective increases to storage fees and return-to-seller and liquidation fees, which Amazon’s own figures show bring the net average change on FBA closer to a £0.02 per-unit increase once both sides are counted. Marketplace strategy growth in 2026 depends less on any single fee change and more on how well a retailer models its specific category and product mix against the full package, not just the headline reduction.
Marketplace strategy growth for UK sellers has a genuinely new number to work with in 2026, following Amazon’s largest package of European fee changes in years. Getting the real impact right matters more than reacting to the headline framing, since the announcement, like most fee updates, presents the changes in the most favourable light for the platform relationship rather than as a neutral summary.
Amazon’s 2026 Fee Changes Reshape Marketplace Margin Calculations
Amazon rolled out its 2026 European fee changes in three phases. From 15 December 2025, FBA fulfilment fees for parcels were reduced by an average of £0.26 per unit across the UK, Germany, France, Italy and Spain stores, building on parcel fee decreases introduced the previous year.
From 5 January 2026, referral fees were cut in several high-volume categories, including Home Products (from 15% to 8% for items up to £20), Pet Clothing and Food (from 15% to 5% for items up to £10), and Grocery, Gourmet, and Vitamins, Minerals and Supplements (from 8% to 5% for items up to £10).
The remaining changes from the original announcement took effect from 1 February 2026, including an extension of Low-Price FBA eligibility to products priced at £20 or under, up from the previous £10 threshold, which Amazon says unlocks an average saving of roughly £0.45 per unit for sellers of low-priced, high-volume goods.
Clothing and Accessories referral fees were also reduced for lower-priced items specifically, cut from 8% to 5% for items priced up to £15 and from 15% to 10% for items priced £15 to £20, which matters given how large a share of UK Amazon sales sits in that category and price band.
The Net Effect Is More Nuanced Than the Headline Reduction
Amazon’s own announcement is worth reading past the headline figure. Alongside the reductions above, the same package includes selective fee increases, specifically to monthly storage fees and to return-to-seller and liquidation fees, plus updated FBA fees in the Netherlands, Sweden, Belgium, Ireland and Poland stores. By Amazon’s own account, once both the reductions and the increases are counted together, the net effect across FBA is closer to an average £0.02 per-unit increase, not the average £0.15 reduction that leads the announcement.
The distinction matters most for the specific parts of a seller’s operation that touch storage duration and returns handling. A seller carrying slow-moving stock for long periods, or with a high proportion of items going through return-to-seller or liquidation, is more exposed to the increases than a seller with fast inventory turnover and low return volumes, regardless of which category discount headline applies to their core product range. The only reliable way to know which side of that balance a specific business sits on is to run its own product mix through Amazon’s Revenue Calculator and Fee and Economics Preview report rather than relying on the announcement’s summary framing.
Marketplace Success Still Comes Down to Visibility and Fulfilment
Fee changes aside, the underlying drivers of marketplace performance haven’t shifted. Visibility within a marketplace’s own search and ranking system remains the primary lever most sellers can influence directly, since a well-optimised listing with strong reviews and consistent stock availability will outperform a poorly optimised one even when both carry identical fee structures. Pricing strategy has to account for the full fee stack, referral fees, fulfilment fees, storage costs, and any applicable digital services or advertising costs, rather than being set against a single headline fee figure that may not reflect a seller’s actual product mix.
Ranking mechanics on a marketplace tend to reward the same underlying signals regardless of which fee package is in effect at a given time: consistent stock availability rather than frequent stockouts, competitive and stable pricing rather than volatile repricing, delivery performance that meets the platform’s own promised speed, and a review profile that reflects genuine customer satisfaction rather than one padded through incentivised reviews, which most marketplaces actively police.
A seller optimising primarily around this season’s fee structure, rather than these underlying ranking fundamentals, is optimising for the wrong variable, since fee packages change annually while ranking fundamentals stay comparatively stable.
Fulfilment method choice remains a genuine strategic decision rather than a default setting. FBA’s fee changes shift the calculation for some sellers toward using Amazon’s fulfilment network more, particularly for low-priced, high-volume goods that now qualify for Low-Price FBA rates, while sellers with slower-moving or bulkier stock may find the storage fee increases push the balance back toward fulfilling some lines themselves or through a third-party logistics provider instead.
Amazon Isn’t the Only Marketplace Worth Watching
Amazon dominates UK marketplace discussion, partly because its fee changes are unusually well documented and partly because of its sheer scale, but it isn’t the only marketplace shaping UK retail. eBay remains a genuine channel for categories where its auction and fixed-price hybrid model and existing buyer base suit the product, particularly in areas like collectibles, refurbished goods, and categories with less new-item price competition than Amazon’s core catalogue.
Social commerce platforms, TikTok Shop being the most discussed example, represent a genuinely different sales mechanism built around content-driven discovery rather than search-driven intent, which suits certain product categories and brand styles better than a traditional marketplace listing ever could.
The strategic point isn’t that every retailer needs a presence on every marketplace. It’s that treating “marketplace strategy” as synonymous with “Amazon strategy” risks missing channels that might suit a specific product range better, and it compounds the single-platform dependency risk discussed below. Evaluating each marketplace on its own merits, rather than defaulting to whichever platform gets the most attention in trade coverage, is worth doing before committing meaningful inventory or marketing spend to any one of them.
Building a Multichannel Strategy Around Marketplaces
For most UK retailers, marketplaces work best as part of a broader channel mix rather than as the sole sales channel. Relying entirely on one marketplace concentrates a retailer’s fee exposure, policy risk, and search-ranking dependency in a single platform that can change its fee structure, as the 2026 changes demonstrate, with limited notice and no negotiation. Retailers running both a marketplace presence and their own store gain a hedge against exactly this kind of platform-level change, since fee increases on one channel don’t affect margin on direct sales through the retailer’s own site.
That doesn’t mean marketplaces should be treated as a lesser channel. Amazon’s own scale, search volume and existing customer trust make it a genuine acquisition channel that’s difficult to replicate through a retailer’s own site alone, particularly for reaching customers who wouldn’t otherwise discover a smaller or newer brand. The practical balance most retailers land on is using marketplaces for discovery and volume while building direct-channel relationships, email lists, and repeat-purchase behaviour that don’t depend on any single platform’s fee structure or ranking algorithm.
FAQs
Did Amazon actually reduce fees for UK sellers in 2026, or increase them? Both, depending on where a seller’s business sits. The headline change is an average £0.15 per-unit reduction, driven by lower FBA fulfilment and referral fees. But the same package includes storage fee and return-to-seller fee increases that, by Amazon’s own figures, bring the net average change on FBA closer to a £0.02 per-unit increase once everything is counted.
Which categories benefited most from Amazon’s referral fee cuts? Home Products, Pet Clothing and Food, Grocery and Vitamins, Minerals and Supplements, and lower-priced Clothing and Accessories items all saw meaningful referral fee reductions in the 2026 changes.
Should a seller switch to FBA because of the Low-Price FBA expansion? It depends on the product. The expanded £20 eligibility threshold particularly benefits high-volume, low-priced goods with fast turnover. Sellers with slower-moving or bulkier stock should model the storage fee increases in the same package before assuming FBA is now cheaper overall.
Is it risky to rely on a single marketplace for most of a business’s sales? Yes, in the sense that fee structures, ranking algorithms and platform policies can all change with limited notice, as the 2026 Amazon fee changes show. A multichannel approach that includes a retailer’s own store reduces exposure to any single platform’s decisions.
Should a UK retailer consider marketplaces beyond Amazon? Yes, depending on the product. eBay suits categories like collectibles and refurbished goods, while social commerce platforms such as TikTok Shop suit brands built around content-driven discovery. The right marketplace mix depends on the product range, not on which platform gets the most attention.
