MARKETPLACE GROWTH

UK Amazon sellers have a structural advantage over overseas competitors since Brexit VAT rules changed — most brands are not capitalising on it

Since January 2021, Amazon UK has been responsible for collecting and remitting VAT on goods sold by overseas sellers. That means non-UK businesses shipping into Britain now face VAT compliance obligations that UK-based sellers do not carry in the same way. The friction is real: overseas sellers must register for UK VAT, navigate customs declarations, and absorb the administrative cost of compliance. UK brands with domestic stock and a valid VAT registration are operating under materially better conditions than most of their international competition.

This is for you if

UK marketplace sellers this work is built for

UK brands on Amazon UK with 10 to 500 active ASINs who have not completed Brand Registry or built A+ Content, and whose PPC accounts have grown without a clear structure.

Etsy UK sellers who have hit a growth ceiling and are not sure whether the constraint is titles, tags, pricing, photography brief, or Etsy's own algorithm changes.

UK brands exporting to EU via Amazon who want to understand how to manage the VAT OSS and marketplace VAT split across Amazon UK and Amazon EU storefronts.

Brands already on Amazon UK who have never tested OnBuy, eBay UK, or Etsy UK as incremental channels and want a structured evaluation before committing resource.

UK product brands with a registered or pending trademark who want to complete Brand Registry quickly and start running Sponsored Brand campaigns.

What's broken

Four things costing UK marketplace sellers ranking and revenue

No review velocity strategy — listing rank erodes without consistent review accumulation.

Amazon UK's algorithm weights review recency and volume. Brands without an automated follow-up sequence — using Jungle Scout, Helium 10, or Amazon's own Request a Review button — collect reviews irregularly and fall behind competitors who run this process on every order. A listing with 200 reviews but none in the past 90 days performs worse than one with 80 reviews accumulated steadily over the same period.

Amazon Brand Registry not completed — A+ Content, Sponsored Brands, and brand protection are all locked.

Brand Registry is the prerequisite for A+ Content modules, Sponsored Brand ads, and Amazon's counterfeit removal process. Most UK brands selling their own branded products on Amazon UK have not completed registration, which means they are running on a bare standard listing while competitors with identical products are running enhanced content. The application requires a registered trademark — we advise on the trademark route for brands that do not yet have one.

OnBuy seller account not set up — an incremental UK-native channel is being left entirely unaddressed.

OnBuy is the fastest-growing UK-native marketplace by seller count. Commission rates are lower than Amazon in most categories. The buyer base is distinct — OnBuy attracts value-conscious UK shoppers who often do not default to Amazon first. For UK brands already carrying FBA or warehouse stock, the marginal cost of listing on OnBuy is low. Most UK brands are not listed.

Listings not updated for post-Brexit UK product compliance terminology.

Some UK Amazon listings still reference CE marking — the EU conformity mark — rather than the UKCA mark that replaced it for products placed on the UK market after January 2021. Incorrect compliance information on Amazon listings can trigger account warnings and, in regulated categories, listing removal. We audit listings for compliance copy and update affected ASINs.

How it works

How we approach marketplace growth for UK brands

  1. 01

    Marketplace audit and baseline.

    Week 1

    We pull ranking data, review velocity, advertising cost of sale, and Buy Box win rate across all active ASINs. We check Brand Registry status, A+ Content coverage, and whether any listings carry outdated compliance copy. We identify which competitor ASINs are ranking above you and why.

  2. 02

    Catalogue and listing prioritisation.

    Week 2

    We rank your ASIN catalogue by revenue, margin, and ranking opportunity. High-revenue ASINs with fixable ranking problems get prioritised first. We identify the 20% of SKUs driving 80% of your marketplace revenue and protect those positions before expanding anything else.

  3. 03

    On-listing optimisation.

    Week 3

    Titles, bullet points, backend search terms, and A+ Content modules are rewritten or built from scratch. Review request sequences are activated. PPC campaigns are restructured around actual search term data rather than assumed keywords.

  4. 04

    Channel expansion.

    Week 4

    OnBuy account creation, catalogue migration, and pricing strategy. eBay UK listing audit where relevant. Etsy UK optimisation for applicable product types.

  5. 05

    Performance monitoring and iteration.

    Ongoing

    Monthly ranking reports, advertising performance reviews, account health checks, and listing updates in response to algorithm changes or competitor activity.

Common questions

Frequently asked questions: UK marketplace growth

How has Brexit changed VAT rules for sellers on Amazon UK and does it help UK-based brands?

Since 1 January 2021, Amazon UK has been designated a deemed supplier for VAT purposes on goods sold by overseas sellers to UK buyers. This means Amazon collects and remits VAT on those transactions rather than the overseas seller doing so directly — but the overseas seller still needs a UK VAT registration in many cases and faces additional customs documentation requirements. UK-based brands with domestic stock already hold a UK VAT registration and do not face the same customs friction at the border. The practical effect is that overseas competitors shipping from EU or non-UK warehouses carry compliance costs and delivery delays that UK-based FBA sellers do not. Most UK brands are not pricing or positioning their listings to exploit this delivery and cost advantage explicitly.

What is Amazon Brand Registry and what does it unlock for UK sellers?

Amazon Brand Registry is a programme that links your registered trademark to your Amazon selling account and grants access to a set of tools that standard seller accounts cannot use. The key unlocks are: A+ Content (enhanced product description modules with images and comparison tables), Sponsored Brand ads (headline search ads that appear above organic results), Brand Store pages (a dedicated storefront within Amazon), and the Report a Violation tool for removing counterfeit or infringing listings. To apply, you need a registered trademark — not a pending application — in the country where you want brand registry. In the UK, this means a trademark registered with the UK Intellectual Property Office (UKIPO).

What is OnBuy and is it worth selling on for UK e-commerce brands?

OnBuy is a UK-founded online marketplace that launched in 2016 and has grown to over 35 million products from tens of thousands of sellers. It is structured differently from Amazon: OnBuy does not sell its own products and does not compete with its sellers. Commission rates vary by category but are generally lower than Amazon's referral fees in comparable categories. OnBuy does not have its own fulfilment network — sellers ship from their own warehouse or use a third-party logistics provider. The buyer base skews toward value-conscious UK shoppers and is meaningfully distinct from Amazon's UK buyer pool. For brands that already hold stock in a UK warehouse and have a product catalogue exportable to a new channel, the incremental cost of listing on OnBuy is low relative to the potential revenue diversification.

How do I build a review velocity strategy that complies with Amazon UK's terms of service?

Amazon prohibits incentivised reviews, review gating (only asking satisfied customers to leave reviews), and any communication that pressures buyers or steers them toward positive feedback. What is permitted: a single follow-up message through Amazon's Buyer-Seller Messaging system that asks the buyer to leave a review, and use of the Request a Review button in Seller Central (or automated via the Amazon API or tools like Jungle Scout). The compliant approach is to automate the Request a Review trigger on every delivered order, ensure the timing is within the 4 to 30 day window after delivery, and monitor review velocity on a weekly basis so you can identify ASINs where accumulation has stalled.

What is the difference between CE and UKCA marks and do I need to update my Amazon UK listings?

The CE mark is the EU's product conformity mark, indicating that a product meets EU safety, health, and environmental requirements. Following Brexit, the UK introduced its own equivalent: the UKCA (UK Conformity Assessed) mark, which applies to goods placed on the market in Great Britain (England, Scotland, Wales). Products placed on the Northern Ireland market continue to use the CE mark under the Windsor Framework. For Amazon UK sellers, listing copy or product images that reference CE marking for products that should carry UKCA may create a compliance discrepancy. Amazon has taken enforcement action on listings with incorrect compliance claims in regulated categories including electrical goods, toys, and PPE. The safest approach is to audit all regulated-category listings and update compliance references to reflect the correct mark for the UK market.
