UK E-Commerce Marketplaces 2026: Best Platforms to Sell Online in the UK — Complete Guide

The 2026 UK Marketplace Landscape at a Glance

The UK marketplace mix is unusually structured: two global giants (Amazon UK, eBay UK), one global craft platform with deep UK roots (Etsy), one fast-growing domestic challenger (OnBuy), and two highly curated specialist channels (ASOS Marketplace, Notonthehighstreet). The chart below summarises the six platforms covered in this guide — keep it nearby as you read each deep-dive section.

1. Amazon UK — The Dominant Player

Amazon UK at a Glance

Amazon UK (amazon.co.uk) is, by almost every metric, the centre of gravity of British e-commerce. Launched by Amazon Inc (founded by Jeff Bezos in Seattle in 1994) on 15 October 1998 as the company's second international marketplace after Germany, Amazon UK now serves 30M+ active customers, hosts 280,000+ active UK third-party sellers and processes a Gross Merchandise Value (GMV) above £45 billion annually. Independent retail-share studies consistently place Amazon's share of UK online retail in the 30% range — the single largest concentration of e-commerce demand at any one channel in the country.

The UK was strategically central to Amazon's early international playbook: it remains one of the company's five "Tier 1" countries, alongside Germany, Japan, France and Italy, with full Amazon Web Services, Prime Video, Music, Kindle, Alexa, Fresh and Whole Foods presence. For third-party sellers, this matters because Amazon UK demand patterns shape the entire UK marketplace landscape: prices on eBay UK, OnBuy and even Etsy are routinely benchmarked against Amazon UK listings.

Amazon Prime UK — The 17M-Member Loyalty Spine

Amazon Prime UK launched in 2007 — the first non-US Prime market — and by 2026 counts over 17 million paying members at the £95/year (£8.99/month) standard tariff. Prime members spend roughly 2.4× more per year than non-Prime Amazon UK customers and convert at significantly higher rates on listings with the Prime delivery badge. From a seller's perspective, this means FBA-eligible (and therefore Prime-eligible) listings dramatically outperform Merchant-Fulfilled listings on equivalent SKUs — internal Amazon data and third-party studies put the Prime conversion lift in the 2–3× range.

FBA UK — The Fulfilment Backbone

Amazon's UK fulfilment network is among the densest of any retailer in the country. Major fulfilment centres include:

• LCY1 / LCY3 — Tilbury, Essex (multi-storey FC serving Greater London)
• MAN1 / MAN2 — Manchester / Trafford Park (Northern England spine)
• EDI4 — Dunfermline, Scotland (Scottish + Northern logistics hub)
• BHX1 / BHX2 — Rugeley + Coventry, West Midlands (geographic centre, fast everywhere)
• BRS1 — Bristol (Southwest UK + Wales corridor)
• + a dozen smaller sortation and last-mile depots covering Northern Ireland, the Highlands and Channel Islands serviceable areas

For UK third-party sellers, FBA UK means access to Amazon's same-day and next-day Prime promise across mainland Great Britain, plus seamless multi-channel fulfilment (MCF) — you can use Amazon's logistics to ship orders that originate on eBay, your Shopify shop or other marketplaces.

Post-Brexit Customs Reality for Amazon UK Sellers

Since 1 January 2021 Amazon's previous "Pan-European FBA" model no longer treats the UK and EU as one logistics zone. Stock in UK FCs serves UK customers; stock in EU FCs serves EU customers; and any movement between them is a customs export and import. For UK sellers selling cross-border, this means either: (a) a dual inventory strategy (UK FBA + EU FBA) with two separate stock pools, (b) Amazon's European Fulfilment Network (EFN) shipping from one country with slower SLAs and customs paperwork, or (c) using Amazon's UK Marketplace + IOSS for sub-£135 EU exports. Zunapro's UK module pre-classifies every SKU with HS codes and surfaces the optimal post-Brexit fulfilment route per channel.

Amazon UK Commission Structure 2026

Amazon UK uses the standard Amazon EU referral-fee schedule — a percentage of the item price, tiered by category. Categories follow Amazon's global buckets:

On top of referral fees, Amazon UK Professional Sellers pay a monthly subscription of £25 (no per-item listing fee). Individual Sellers pay £0.75 per item sold instead of the monthly fee — only economical below ~33 items/month.

Buy Box, Repricing and Brand Gating on Amazon UK

As with every Amazon marketplace, the Buy Box (now formally "Featured Offer") — the orange "Add to Basket" button on the right-hand side of the product page — is the entry point for the vast majority of sales, frequently more than 83% of total volume on a given listing. Winning it requires a tight combination of price competitiveness, FBA status, account health (Order Defect Rate, Late Shipment Rate), shipping speed, and seller history. Zunapro's repricer module integrates with Amazon's Selling Partner API (SP-API) to adjust prices every few minutes within seller-defined floors and ceilings.

UK sellers should also note Amazon UK's Brand Gating regime — categories like beauty, luxury fashion and certain electronics require pre-approval to list, with documented brand authorisation (invoices from the manufacturer or authorised distributor). Brand-gating denials in 2026 are increasingly enforced by automated supplier-network analysis.

2. eBay UK — The Heritage Marketplace

From AuctionWeb to eBay.co.uk

eBay Inc was founded by Pierre Omidyar in San Jose in September 1995 as AuctionWeb, on a personal site Omidyar registered to share information about Ebola research — the auction was a side project that consumed the rest. eBay UK (ebay.co.uk) launched on 14 October 1999, making it the UK's longest-running consumer e-commerce marketplace by a wide margin and one of the oldest internet brands still operating in Britain.

By 2026 eBay UK reports 17M+ active UK buyers and roughly 300,000+ active UK sellers, with annual UK GMV in the £12B+ range. While Amazon eclipsed eBay on raw new-product sales in the late 2010s, eBay UK retains a deep, distinctive culture around second-hand, refurbished, vintage, automotive parts, collectables and clearance — categories Amazon serves less well. The 2024 launch of eBay's "Pre-loved Fashion" initiative (alongside the Love Island sponsorship) marked a strategic doubling-down on circular commerce as a core UK proposition.

eBay UK Listing Models — Auction, Buy It Now, eBay Shops

eBay UK still supports both auction-style listings and fixed-price ("Buy It Now") listings. Most professional sellers in 2026 list almost exclusively Buy It Now — auctions remain valuable for unique or vintage SKUs where price discovery matters more than throughput. eBay Shops (Starter, Basic, Featured, Anchor, Enterprise — from £24/month to £300/month) reduce final value fees, increase free monthly listings, and unlock the seller-branded storefront UI.

eBay UK Final Value Fees 2026

eBay UK's fee structure has two main components: an insertion fee (waived for the first 1,000 listings/month for Business sellers without a Shop subscription, more if subscribed), and a Final Value Fee (FVF) on each successful sale. The 2026 FVF structure:

On top of the percentage FVF, eBay UK charges £0.30 per order as a fixed transaction fee. The "all-in" effective rate on most categories is therefore in the 13–14% range for the average parcel. Pre-loved fashion has been periodically zero-FVF as part of eBay's circular-commerce push — current 2026 policy is "buyer's fee only" on private listings under £1,000, with business sellers paying standard rates.

eBay Promoted Listings (Standard, Advanced, Offsite)

Promoted Listings Standard is eBay UK's CPS (cost-per-sale) advertising product — sellers set an ad rate (typically 2–12% of sale price) and only pay if the buyer clicks the promoted listing and converts within 30 days. Promoted Listings Advanced is a CPC product giving keyword-level control. Promoted Listings Offsite uses Google Shopping and Meta to drive external traffic on a CPS basis. For competitive categories — fashion, refurbed phones, branded sneakers — running ~4% Promoted Listings Standard is effectively table stakes in 2026 to win the top organic-equivalent slots.

3. Etsy — Global Handmade & Vintage Marketplace

From a Brooklyn Apartment to a NASDAQ Listing

Etsy was founded in June 2005 in a Brooklyn apartment by Rob Kalin, Chris Maguire and Haim Schoppik as a craft-focused alternative to eBay. The platform's defining proposition has remained unchanged: items must be handmade, vintage (20+ years old), or a craft supply — generic mass-produced retail is explicitly banned. Etsy IPO'd on NASDAQ:ETSY in April 2015 at a $1.8B valuation and by 2026 carries a market cap fluctuating in the $8–14B range, with 95M+ active global buyers and 9M+ active sellers worldwide.

The UK is Etsy's #2 country by both seller and buyer base after the US. There are roughly 350,000+ active UK Etsy sellers in 2026 — overwhelmingly small businesses, craftspeople and side-hustle creators — generating a UK Etsy GMV estimated at over £3 billion annually. The platform is the default channel for any UK creative selling jewellery, ceramics, prints, knitwear, soaps, candles, calligraphy, paper goods, vintage clothing or curated craft supplies.

The Etsy Star Seller Programme

Etsy Star Seller launched in 2021 as a quarterly badge for sellers who consistently meet four criteria: 95%+ five-star reviews, 95%+ on-time despatch with tracking, 1-business-day average message response time, and £300+ sales in the qualifying period. The badge appears prominently on listings and shop pages and demonstrably lifts conversion — Etsy's own studies cite a 5–10% conversion uplift on Star Seller listings versus non-Star equivalents. By 2026 roughly 20% of active UK Etsy sellers carry the Star Seller badge in any given quarter.

Etsy Fee Structure 2026 — Not As "Low" As It Looks

Etsy's headline "6.5% transaction fee" is famously misleading because there are three additional charges most sellers eventually pay:

• Listing fee — $0.20 per item (in USD, every 4 months) regardless of whether it sells
• Transaction fee — 6.5% of the item price + shipping
• Payment processing fee — 4% + £0.20 on UK GBP transactions (via Etsy Payments)
• Offsite Ads fee — 12% or 15% when a sale comes from Etsy's external ad campaigns (mandatory for sellers above £8K/year; opt-in below)
• Etsy Ads — optional on-site CPC budget, fully discretionary

The realistic "all-in" Etsy fee on a typical £25 UK SKU sold organically is roughly 9–12%; on a SKU sold via Offsite Ads it can exceed 20%. This matters because Etsy's positioning as a "low-fee" channel relative to Amazon UK no longer holds in 2026 — Etsy and Amazon UK are roughly comparable on net take-rate for mid-AOV SKUs.

4. OnBuy — UK's Fastest-Growing Challenger

Built in Bournemouth, Built for the UK

OnBuy was founded in 2016 in Bournemouth, Dorset, by Cas Paton — a former trader who'd spent a decade selling on Amazon UK and eBay UK and became increasingly frustrated with their commission rates and seller-treatment policies. OnBuy's pitch is deliberately positioned in the gap Paton saw: a UK-only marketplace with commission rates roughly half of Amazon UK's, no headline Buy Box war, no aggressive supplier acquisition by the marketplace itself, and a customer-acquisition strategy built on PayPal partnership (PayPal as the default checkout) and BNPL via Klarna and Clearpay.

By 2026 OnBuy reports 8M+ UK shoppers, 35,000+ active UK sellers and is consistently cited in trade press as the UK's fastest-growing mainstream marketplace by relative volume. Categories with strongest momentum are health & beauty, home & garden, sports & leisure, consumer electronics and pet supplies — exactly the long-tail categories where Amazon UK's 15% commission punishes resellers most.

OnBuy's 5–9% Commission — The Headline Number

OnBuy's commission sits in a 5–9% band depending on category and subscription tier:

OnBuy operates two main subscription plans:

• Partner — £19/month: standard commission rates, full feature set, suitable for most SMEs
• Partner+ — £39/month: reduced commission rates (typically ~1–2 percentage points lower), priority support, advanced analytics

For a £100 SKU in consumer electronics, OnBuy's 5% commission delivers the seller £95 net — versus Amazon UK's 8% referral + £25/month subscription, where the same SKU nets approximately £92 before FBA. The gap widens in fashion: OnBuy's 9% on a £100 fashion SKU nets £91, versus Amazon UK's 15.3% netting around £85.

Why OnBuy Works as a Mirror Channel

OnBuy is not (yet) a replacement for Amazon UK reach. The pragmatic 2026 OnBuy strategy is to mirror your Amazon UK / eBay UK catalogue to OnBuy at identical or marginally higher prices, capture the incremental margin on every OnBuy sale, and keep stock perfectly in sync to avoid overselling. Zunapro automates this exact mirror flow: master SKUs feed Amazon UK + eBay UK + OnBuy in parallel, with central inventory deduction the moment any of the three sells.

5. ASOS Marketplace — Curated Boutique + Vintage Fashion

The 2010 Spin-Off That Became a Talent Funnel

ASOS plc (As Seen On Screen) was founded in June 2000 by Nick Robertson and Quentin Griffiths as a London-based online fashion retailer for 16–34-year-olds. It listed on AIM in 2001 and grew through the 2000s into one of the UK's defining digital-native fashion brands. ASOS Marketplace (marketplace.asos.com) launched in 2010 as a curated channel for independent fashion boutiques and vintage curators — small, design-led brands that ASOS's main own-buy team would never stock at scale, but that ASOS's young, fashion-forward audience explicitly wanted to discover.

By 2026 ASOS Marketplace hosts roughly 900+ vetted boutiques across the UK, Europe and the US, with an inventory dominated by vintage, one-of-a-kind, indie designer and small-batch SKUs. The marketplace is a strategic talent funnel for ASOS: brands that perform well on the Marketplace are sometimes promoted to ASOS's own-buy catalogue, and the Marketplace itself benefits from sitting one click away from ASOS's main 23M-strong customer audience.

Application + Curation Process

ASOS Marketplace is application-only. Prospective boutiques submit at marketplace.asos.com/sell with a portfolio of 30+ unique SKUs, brand-quality photography, a coherent aesthetic and proof of independent ownership. The ASOS curation team reviews each application; industry estimates put the acceptance rate at 25–35%. Successful boutiques get a custom branded storefront within the Marketplace, access to ASOS Marketplace's editorial features and the ability to participate in seasonal curated edits.

ASOS Marketplace Fees 2026

The 20% commission is significantly higher than Amazon UK or OnBuy — but the audience quality justifies it for the right boutique. Independent fashion brands targeting 18–30-year-olds with distinctive aesthetic positioning generally find ASOS Marketplace one of the highest-quality UK channels available, and a meaningful PR / brand-awareness lift comes from the Marketplace's editorial features alone.

6. Notonthehighstreet — Curated UK Gifts & Personalised

Two Mums, a Garage and a 5,000-Partner Marketplace

Notonthehighstreet (NOTHS) was founded in 2006 by Sophie Cornish and Holly Tucker in West Sussex, with the explicit goal of being a digital home for the UK's small creative businesses — the makers, designers, calligraphers, ceramicists and print studios who would not naturally find a home on Amazon UK or eBay UK. The founding insight was that British consumers shopping for gifts, personalised items and home pieces wanted curation, craft and storytelling — not bulk retail. The company received early VC investment, scaled rapidly through the 2010s, and was acquired by Hg Capital in 2019; under Hg's ownership the platform has refocused on profitable growth, tighter Partner curation, and a stronger personalised-gifts proposition.

By 2026 NOTHS hosts roughly 5,000+ active "Partners" (its term for sellers), generates annual GMV estimated at £150M+, and is the UK's leading destination for personalised gifts, occasion homeware, jewellery, prints and lifestyle products. Average order value is markedly higher than mass marketplaces — the typical NOTHS basket sits in the £35–£60 range versus Amazon UK's £25–£30 mean — reflecting the gifting context.

The Partner Application Process

NOTHS is rigorously curated. Prospective Partners apply via the Partner portal with: photography of their product range, an explanation of their craft / design process, evidence of UK-based small-business ownership, and an articulated personalisation or differentiation angle. The Partner Success team reviews each application; approval rates are similar to ASOS Marketplace — in the 20–30% range — and the criteria emphasise creative differentiation, photography quality and the personalisation hook.

NOTHS Fee Structure 2026

The 25% commission is the highest of any mainstream UK marketplace in this guide — but for the right craft / personalised-gift Partner the trade-off is favourable: the audience is gift-context, high-intent and high-AOV; the editorial merchandising places curated products in front of buyers who are explicitly NOT comparing against Amazon UK; and the gifting calendar (Mother's Day, Father's Day, Valentine's, Christmas, weddings) drives demand peaks that are bigger and earlier than the mass marketplaces.

Commission Comparison Table 2026 — All Six UK Marketplaces

The single most useful artefact for choosing where to sell is a side-by-side commission view. The table below summarises 2026 commission bands and the platform's vendor / subscription fee structure.

Marketplace	Low Tier	Mid Tier	High Tier	Vendor / Subscription Fee
Amazon UK	7% – 8%	12% – 15%	15% – 17%	£25 / month Professional Selling Plan + FBA fees
eBay UK	9% – 11%	12.8% (standard)	13% – 14%	Free account + £0.30 per order · eBay Shops £24–£300/mo
Etsy	6.5% transaction + 4%+£0.20 payment processing + $0.20 listing fee · effective 9–12%			Optional Etsy Ads / Offsite Ads 12–15%
OnBuy	5% – 6%	6% – 8%	8% – 9%	Partner £19/mo · Partner+ £39/mo (reduced commission)
ASOS Marketplace	20% flat commission across all fashion + vintage categories			£20 setup + £20/mo boutique subscription
Notonthehighstreet	25% flat commission across all categories			£199 joining + £40/mo Partner subscription

Reading the table: OnBuy is structurally the cheapest mainstream channel in 2026 at 5–9%, with Amazon UK and eBay UK roughly equivalent in the 12–15% mid-tier zone. Etsy's "6.5%" headline understates real cost — the true take rate sits in the 9–12% band. ASOS Marketplace and Notonthehighstreet sit at the high-fee end (20% and 25% respectively), justified by audience curation and high-AOV gifting / fashion context. The 2026 winning configuration for most UK SMEs is Amazon UK + eBay UK as reach spines, OnBuy as a margin mirror, plus 1–2 curated specialists (Etsy, ASOS Marketplace or NOTHS) matched to product fit.

UK Legal & Compliance Framework 2026

UK VAT, HMRC and the Three Rates

The United Kingdom's VAT regime, administered by HMRC (His Majesty's Revenue and Customs), applies three core rates:

• Standard rate — 20% on most goods and services (consumer electronics, fashion, homeware, beauty, most retail)
• Reduced rate — 5% on domestic energy, children's car seats, mobility aids for the elderly and a short list of social-welfare categories
• Zero rate — 0% on most foods, children's clothing, books, newspapers, prescription medicines and certain export categories

UK-established sellers register for VAT once their taxable turnover exceeds £85,000 (the 2026 UK VAT threshold). Non-UK-established sellers selling into the UK have no threshold — VAT is due from the first £1 of UK sales, and registration is mandatory before any sale is shipped to a UK customer.

Making Tax Digital (MTD) for VAT — Mandatory from April 2026

Making Tax Digital (MTD) is the most significant compliance change of 2026 for UK marketplace sellers. From April 2026, MTD for VAT is mandatory for every VAT-registered business in the UK, regardless of turnover — the previous threshold-based exemptions (£85,000, then £30,000 from 2024) end. The MTD regime requires:

• Digital VAT records — every sale, purchase and adjustment must be stored in software (no manual ledgers / spreadsheets standing alone)
• Digital links — data must flow from source (marketplace, point of sale, accounting system) to VAT return without manual copy-paste
• Submission via the MTD API — VAT returns must be filed to HMRC via approved MTD-compatible software, not via the legacy HMRC web portal
• Quarterly return cycle retained, plus the existing requirement to keep records for six years

For sellers active on Amazon UK, eBay UK and other marketplaces simultaneously, the MTD digital-link requirement makes a unified ledger essential. Zunapro consolidates every marketplace order — including the per-order eBay UK £0.30 fee, Etsy Offsite Ads commission, OnBuy subscription, FBA fulfilment fee and Royal Mail postage cost — into an MTD-compatible VAT ledger and files returns directly to HMRC via the MTD API.

UK GDPR + Data Protection Act 2018

Since Brexit the UK has its own data-protection regime, the UK GDPR, supplemented by the Data Protection Act 2018, enforced by the Information Commissioner's Office (ICO). The UK GDPR is substantively identical to the EU GDPR in 2026 (the UK retained the framework verbatim at the point of departure) but is now legally independent. UK marketplace sellers must respect the same data-subject rights (access, rectification, erasure, portability), maintain a Record of Processing Activities, and report personal-data breaches to the ICO within 72 hours.

Consumer Contracts Regulations — 14-Day Right of Withdrawal

The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 implement the EU Consumer Rights Directive in UK law. UK consumers buying online (or otherwise at a distance) have an unconditional 14-day right of withdrawal from delivery — they can return any product within 14 days for any reason (or no reason), and the seller must refund within 14 days of return receipt. The 14-day clock starts when the goods are physically received, not when ordered.

Consumer Rights Act 2015 — The 6-Year Statutory Warranty

The Consumer Rights Act 2015 (which consolidated and replaced the Sale of Goods Act 1979 for B2C transactions) imposes three implied terms on every B2C sale: that goods must be of satisfactory quality, fit for purpose and as described. Under the Limitation Act 1980, a consumer's right to bring a claim runs for up to six years from the date of sale in England, Wales and Northern Ireland (five years in Scotland). This is independent of any commercial guarantee; sellers cannot contract out of it.

In practical terms, "6-year warranty" claims are limited: the consumer must demonstrate the fault existed at the point of sale (or was inherent) and not from wear and tear. Premium electronics and white goods are the most common categories where Year 4–6 claims appear.

Post-Brexit Customs, EORI, IOSS

Since 1 January 2021 every UK → EU and EU → UK shipment is a customs movement. UK-established marketplace sellers shipping cross-border need:

• GB EORI number — required for export customs declarations from the UK (free, applied for via gov.uk, typically issued within 1 week)
• EU EORI number — required if the seller acts as importer of record on the EU side; obtained from any EU member state's customs authority
• IOSS (Import One Stop Shop) registration — for B2C parcels under €150 into the EU, IOSS lets the seller charge EU VAT at checkout and remit via a single EU VAT registration
• Commercial invoices — every parcel needs a 2-copy commercial invoice with HS code, value, country of origin and IOSS number
• HS / Commodity codes — 8-digit (export) or 10-digit (import) classification per SKU

Marketplaces themselves act as "deemed suppliers" under UK and EU rules: Amazon UK, eBay UK and Etsy collect and remit VAT on imports under £135 (UK) or €150 (EU) for non-resident sellers, simplifying compliance but requiring careful invoice categorisation.

Trading Standards, OPSS and Product Safety

UK product-safety oversight is split between Trading Standards (local-authority enforcement of consumer-protection law, primarily reactive) and the Office for Product Safety and Standards (OPSS), the national regulator established in 2018 under the Department for Business and Trade. OPSS sets and enforces general-product-safety regulations (the UK GPSR — Product Safety and Metrology etc Statutory Instrument), regulates CE / UKCA marking (UKCA has been postponed indefinitely as of mid-2026, with CE marking still recognised in Great Britain), and runs the Product Safety Database for incident reporting.

Logistics & Shipping in the UK — Royal Mail, Evri, DPD UK

Royal Mail — The Default Spine

Royal Mail, a private company since 2013 (formerly Royal Mail Group plc, now part of International Distributions Services plc — IDS), remains the single most important parcel and letter operator in the United Kingdom. Its public-service heritage (which extends to a Universal Service Obligation requiring 6-day-a-week delivery to every UK address at uniform pricing) gives it the densest UK delivery footprint and the widest postcode coverage — including the Highlands, the Hebrides, Northern Ireland, the Isle of Man, the Channel Islands and the Isles of Scilly.

For marketplace sellers, the key Royal Mail products in 2026 are:

• Royal Mail Tracked 24 / 48 — next-day and 2-day tracked parcel services, baked into Amazon UK Buy Shipping, eBay UK Simple Delivery and Etsy UK postage labels
• Royal Mail Signed For — proof-of-delivery signature for high-value parcels
• Royal Mail International Tracked & Signed — flagship cross-border product for UK → EU and global
• Royal Mail Click & Drop — self-service portal for SMEs printing labels in bulk
• Royal Mail Business Account — corporate billing, OBA (Online Business Account) tariffs, collection slots

Evri — The Cost Leader (formerly Hermes UK)

Evri rebranded from Hermes UK in 2022 — a deliberate effort to reset a brand reputation that had suffered through the Covid-era parcel-volume surge. Operating through a network of self-employed couriers and ParcelShops, Evri is the price leader for lightweight B2C parcels up to 5kg, integrating natively with eBay UK, Amazon UK Buy Shipping, Vinted, Depop and most third-party shipping platforms. Typical 2026 Evri prices: £2.45 for a 1kg parcel via ParcelShop drop-off, vs Royal Mail's £4.95 for the equivalent tracked service. The savings matter for low-AOV SKUs.

DPD UK — The Premium Next-Day

DPD UK (part of the French postal group La Poste's DPDgroup) is the UK's leading premium 1-day parcel operator, particularly strong on next-day predicted-window technology — DPD's app lets recipients track parcels in 15-minute windows and re-route deliveries to a neighbour or DPD Pickup point in real time. The premium pricing (typically £6–£9 for a 5kg next-day parcel) makes DPD UK best suited to £100+ AOV electronics, fashion and DIY. Amazon UK FBA uses DPD UK as one of its principal carrier partners for non-Prime fast-track parcels.

The Wider Courier Layer

• Yodel — independent UK courier focused on lightweight to medium B2C parcels at competitive rates
• DHL Express UK — international premium and time-definite UK domestic; the cross-border export standard
• DHL Parcel UK — domestic-focused budget product, mainly for 2kg+ parcels
• UPS UK — strong on B2B and high-value international; less common for B2C marketplace traffic
• FedEx UK — international air, premium UK domestic, frequently bundled with DHL for cross-border
• Parcelforce — Royal Mail Group's larger-parcel arm (>2kg), often invisibly used inside Royal Mail "Tracked" tiers
• InPost UK — yes, the Polish locker giant: ~6,000+ UK lockers in 2026, growing fast through Vinted, ASOS and Amazon UK locker drop-off
• Amazon Logistics (AMZL_UK) — Amazon's own last-mile for FBA and Prime parcels in major UK metros

Practical UK Shipping Stack 2026

The pragmatic 2026 UK marketplace shipping stack is: Royal Mail Tracked 48 as the default for B2C parcels under 2kg with no time-definite SLA, Evri for low-margin SKUs where cost beats brand, DPD UK for £100+ AOV next-day premium, DHL Express UK for international and Parcelforce / DHL Parcel UK for 2–20kg parcels where Royal Mail Tracked is uneconomical. Zunapro's logistics module routes each marketplace order to the optimal carrier based on weight, AOV, destination postcode, marketplace SLA commitment and the seller's negotiated carrier rates.

Post-Brexit Cross-Border Selling — UK ↔ EU in 2026

Five Years Embedded, Still Operationally Complex

By 2026 the post-Brexit customs regime is five years old — the operational kinks are largely worked out, but UK → EU and EU → UK shipments remain materially more complex than pre-2021 domestic shipping. The basic facts: every UK → EU parcel is a customs export and import, every EU → UK parcel is a customs export and import, and the responsibility for VAT, duty and declarations depends on (a) the parcel value, (b) whether the seller or buyer is the importer of record, and (c) whether the marketplace is a "deemed supplier" under the destination rules.

UK → EU: The IOSS Route for Under-€150

For B2C parcels valued under €150, UK sellers should register for IOSS (Import One Stop Shop) via any EU member state's tax authority. IOSS lets the seller charge the destination-country EU VAT at checkout (e.g. 19% for Germany, 20% for France, 21% for the Netherlands), remit it via a single monthly IOSS return, and ship customs-cleared parcels into the EU with no VAT or duty payable on delivery. This produces a customer experience equivalent to pre-Brexit shipping.

UK → EU: The Over-€150 / DDP Route

For parcels over €150, IOSS does not apply. Either (a) the EU customer is the importer of record and pays VAT plus duty on delivery (typically a poor customer experience — couriers charge a £8–£15 handling fee on top), or (b) the seller ships DDP (Delivered Duty Paid), prepaying VAT and duty via the courier and absorbing the cost into the headline price. DDP is the strong 2026 default for premium UK exporters into the EU. Royal Mail International, DPD, DHL Express and FedEx all offer DDP services.

EORI Numbers — Required Both Sides

• GB EORI — required for export declarations from the UK. Free via gov.uk, typically issued within 5 working days. Format: GB + 12-digit number (often the VAT number padded with 000)
• EU EORI — required if the UK seller acts as importer of record on the EU side (for DDP or for stock-into-EU-warehouse flows). Obtained from any EU member state's customs authority; once issued, valid across all 27 EU countries.
• Indirect Customs Representative (ICR) — for sellers who do not want to register their own EU EORI, a logistics partner can act as ICR on the seller's behalf, taking on shared liability for the customs declaration

The Cross-Border Sales Stack

• Catalogue: master SKUs in Zunapro, mirrored to Amazon UK + Amazon DE/FR/IT/ES, eBay UK + eBay DE, Etsy global
• Pricing: multi-currency rules (GBP, EUR) with daily ECB rate sync, DDP markup logic for over-€150
• Compliance: MTD VAT for UK, IOSS for EU sub-€150, EU OSS or country-by-country for EU domestic stock, country-specific WEEE/PRO obligations
• Logistics: Royal Mail International Tracked + DPD/DHL DDP for cross-border
• Returns: dedicated EU return-address (often Netherlands or Ireland-based) to avoid customs roundtripping

How to Start Selling in the UK — 2026 Step-by-Step

1. Choose Your Marketplaces (Decision Tree)

• Maximum reach, any category, FBA-friendly → Amazon UK
• Second-hand, refurb, automotive parts, collectables, vintage → eBay UK
• Handmade, vintage, craft supplies, design-led small batch → Etsy
• Margin protection on a generalist range, lower-fee mirror channel → OnBuy
• Independent fashion / vintage brand targeting 18–30-year-olds → ASOS Marketplace
• Personalised gifts, occasion homeware, curated craft → Notonthehighstreet

The typical winning 2026 configuration is Amazon UK + eBay UK + OnBuy as the volume / mirror combination, plus one curated specialist channel (Etsy, ASOS Marketplace or NOTHS) chosen by product fit. All channels mirrored from a single master catalogue.

2. UK Company or Non-UK Established Seller Path

You have three legal-entity options:

• UK Limited Company (Ltd) — incorporated via Companies House for £12 (online), typically registered within 24 hours, requires a UK registered office address. Standard route for serious UK marketplace sellers.
• UK Sole Trader (Self-Employed) — register with HMRC for Self-Assessment, no separate legal entity. Lowest overhead, suitable for under-£85K turnover side businesses.
• Non-UK Established Seller (NETP) — keep your existing foreign company, register for UK VAT directly with HMRC (no UK establishment required), obtain a GB EORI, sell into the UK with marketplaces (Amazon UK / eBay UK / Etsy) handling deemed-supplier VAT on under-£135 imports.

3. MTD VAT Registration (Mandatory from April 2026)

Whichever entity you choose, MTD VAT compliance is non-negotiable from April 2026. The setup steps:

• Obtain a VAT registration number (GBxxxxxxxxx) via HMRC's online portal — UK established sellers at £85K turnover threshold; non-UK established sellers from the first £1
• Sign up for MTD for VAT via the HMRC Government Gateway portal
• Connect MTD-compatible software (Zunapro is HMRC-recognised) to receive a fraud-prevention header token
• Maintain digital records for every sale, purchase and VAT adjustment
• Submit quarterly VAT returns via the MTD API

Zunapro handles all five steps automatically when your marketplace orders are received, including the per-marketplace deemed-supplier carve-outs (Amazon UK and eBay UK collect VAT on certain transactions; those go to a separate ledger column to avoid double-counting).

4. Royal Mail and Evri Carrier Integration

Open a Royal Mail Online Business Account (OBA) and connect via API or Click & Drop for label printing. Open an Evri Business Account for low-cost lightweight parcels. For premium, add DPD UK via their MyDPD Business API. Amazon UK Buy Shipping and eBay UK Simple Delivery already bundle Royal Mail, Evri and DPD UK in their default shipping panels, but for cross-channel consistency you'll want direct carrier API connections via Zunapro's logistics module.
