What the UK dataset covers
21,920 Amazon.co.uk storefronts tracked — the largest independent UK marketplace scrape available from The Sellers Index
What you get per UK seller
Each record is checked against Companies House and HMRC systems before it enters the deliverable dataset. Dissolved or dormant entities are excluded at source.
SMTP-handshaked for deliverability before inclusion. Not a generic info@ — a deliverable business contact address.
Cross-referenced against Companies House. Dissolved or dormant entities are excluded before the record is written.
Validated through HMRC and VIES systems. Includes post-Brexit UK VAT registration — not just EU VAT.
Registered office address as recorded by Companies House at the time of verification. Not a mailing address — a legal entity address.
Where the business actually operates — not where it lists products. Distinguishes UK-registered companies from overseas entities selling on .co.uk.
Full Intelligence tier delivers all 11 enriched fields including a ready-to-use business summary and the exact timestamp of last verification.
Cross-border intelligence
67.2% of the 21,920 Amazon.co.uk storefronts tracked operate from China. Only 26.7% are genuinely UK-based entities. That distinction drives the entire compliance and outreach strategy.
Our base-country field lets you filter the universe by where sellers actually operate — not just where they list. The same dataset that reveals 14,740 China-origin storefronts also pinpoints the ~5,860 UK-registered businesses that represent the cleanest domestic outreach target.
Target the 67.2% China-based cohort on Amazon.co.uk — the primary audience for EU Representative obligations post-Brexit.
Isolate the 26.7% UK-registered sellers for Companies House-referenced campaigns — zero ambiguity on legal entity status.
Identify German, French, and US brands expanding into Amazon.co.uk — a distinct sub-segment within the remaining 6.1%.
This cross-border intelligence is proprietary to The Sellers Index. No other UK amazon seller data provider offers it.

Technical foundation
Two registries. One pipeline. Every record auditable against the same public sources your compliance team would check manually.
Every seller entity is cross-referenced against the UK's official business registry. If a company is dissolved or dormant, it does not enter our amazon leads database. Only active, registered entities make it through — with the CRN attached.
VAT IDs are verified through HMRC and VIES systems — not inferred from public listing data. This is the field compliance providers and logistics agencies targeting active traders need before any outreach. Data current as of February 2026.
Every email address undergoes a live SMTP handshake before the record is written. Our pipeline absorbs the cost of filtering bounces before they reach your dataset. If hard bounce rate exceeds 5% within 7 days of purchase, we provide 2x credit replacement.
Why a UK-specific database
UK GDPR, post-Brexit VAT rules, and a Companies House registry that is unique to Great Britain mean a UK Amazon seller database that ignores those distinctions is closer to a list than a dataset. It cannot be used cleanly for legitimate-interest outreach, cannot be reconciled against HMRC, and cannot be defended in a regulator query.
Every record in our UK Amazon seller database is checked against Companies House at the entity level, validated through HMRC for VAT status, and tagged with the registered office address as recorded by Companies House at the time of verification (data as of February 2026). The database is built for buyers who need to know which sellers are UK-registered limited companies and which are overseas entities operating on the .co.uk marketplace.
The Sellers Index is ICO-registered and processes data under UK GDPR legitimate interest for B2B contacts. Companies House data is used under Open Government Licence. VAT validation uses official HMRC systems.

UK Amazon marketplace · market data 2026
The UK Amazon marketplace contains 21,920 tracked third-party sellers as of early 2026, making it the second-largest European marketplace in The Sellers Index universe. Origin concentration is pronounced: 67.2% of those sellers — 14,740 storefronts — operate from China, while 26.7% are genuinely UK-based businesses. That disparity has direct implications for compliance providers, EURP representatives, and logistics agencies whose serviceable market sits almost entirely in the cross-border cohort.
Across those 21,920 sellers, the average marketplace rating holds at 4.57 — a figure that points to a maturing seller base rather than a churn-heavy entry market. UK-registered sellers form the next largest segment and are the primary audience for Companies House-referenced outreach campaigns.
The full breakdown of seller origins and segment sizes is published in The Sellers Index 2026 reports: see the UK Amazon sellers 2026 dataset and the State of Amazon Sellers 2026 for cross-market context.
