UK marketplace at a glance: 21,920 storefronts, 67.2% China-origin
The UK Amazon marketplace is the second largest in the TSI dataset at 21,920 storefronts — 32.5% of the 67,416 total. China-origin sellers dominate at 67.2% (14,740 storefronts), though the UK marketplace has a notably higher proportion of GB-registered sellers than the US marketplace — 26.7% (approximately 5,860 storefronts) versus 19.8% for US-origin sellers in the USA marketplace. US-origin sellers account for 1.3% of UK marketplace storefronts. Hong Kong-registered entities represent around 2.1% of the UK marketplace (approximately 468 storefronts). The average seller rating across all 21,920 UK marketplace storefronts is 4.57. This figure is lower than the USA marketplace average of 4.68 but within a narrow range, suggesting broadly similar competitive quality standards across the two markets. Data quality is high: 93.5% of storefronts carry a verified rating. See the France Amazon Sellers 2026 report for comparison with the third marketplace.

VAT ID visibility on the UK marketplace: a compliance lens
The TSI dataset captures VAT ID visibility — whether a storefront displays a VAT identification number — for sellers on the UK marketplace. This is a visibility metric derived from public storefront data and does not constitute verified HMRC registration, but it provides a useful proxy for formal compliance posture. Among the 14,740 CN-origin sellers on the UK marketplace, 80.6% show a VAT ID on their storefront. For GB-origin sellers (5,860 storefronts), the rate is 64.3% — lower than Chinese sellers, which may reflect a difference in VAT registration incentives or the timing of the post-Brexit regulatory changes that required non-UK sellers to register for VAT. Hong Kong-origin sellers show the highest VAT visibility rate in the dataset at 86.1% (across 468 storefronts), and US-origin sellers are highest among Western-origin cohorts at 92.2% (283 storefronts). These figures should be interpreted as awareness indicators, not compliance certification.
| Origin | Storefronts | VAT ID visible | Visibility rate |
|---|---|---|---|
| United States (US) | 283 | ~261 | 92.2% |
| Hong Kong (HK) | 468 | ~403 | 86.1% |
| China (CN) | 14,740 | ~11,881 | 80.6% |
| United Kingdom (GB) | 5,860 | ~3,768 | 64.3% |
Storefront quality and review depth on the UK marketplace
The UK marketplace average storefront rating of 4.57 places it slightly below the USA marketplace (4.68) but in the same competitive band. GB-origin sellers on the UK marketplace average 214 reviews per storefront — reflecting established tenure and local consumer trust — compared to 98 reviews per storefront for CN-origin sellers. This review-count gap is consistent with the global pattern: Chinese sellers have typically been present on Western Amazon marketplaces for fewer years than local sellers, producing a lower average review accumulation even when product quality and fulfilment standards are comparable. Product catalogue depth is consistent across origins, with the average storefront listing approximately 4 products. The UK marketplace's competitive structure is therefore characterised by high seller volume in a narrow quality band — most sellers cluster between 4.4 and 4.8 stars — making rating alone a poor differentiator and putting category, price, and review velocity at the forefront of competitive strategy.
What the UK seller data means for list-buyers and compliance providers
The UK Amazon marketplace's 21,920-storefront dataset is the most commercially relevant cohort for UK-based B2B service providers. For outreach agencies using a UK Amazon seller database, the 67.2% China-origin majority (14,740 sellers) means that a significant share of any purchased list will require cross-border contact strategy: Chinese-language communications, WeChat or Alibaba Messenger outreach pathways, and timezone-adjusted email scheduling. The 26.7% GB-origin cohort (5,860 sellers) is the most accessible segment for UK-based service providers, with domestic addresses, English-language operations, and the highest likelihood of in-person event or phone follow-up. The VAT visibility data adds a compliance-targeting dimension: the 35.7% of GB-origin sellers (roughly 2,092 storefronts) who do not show a VAT ID represent a potential compliance advisory audience — traders who may be approaching or past the VAT registration threshold without visible HMRC compliance on their storefront. This non-visible group can be identified in the enriched dataset and represents a highly specific, high-conversion target for UK VAT advisory firms. Cross-referencing origin, VAT visibility, and primary product category creates precise sub-segments for specialist service providers across all three commercial dimensions. The full enriched UK dataset — including verified emails and Companies House cross-reference where available — is accessible via the TSI platform.
