The top marketplaces in the United Kingdom (2026)

1) Amazon.co.uk

The UK's most visited marketplace and default starting point for product search; FBA and Prime remain conversion engines (Similarweb).

• Suits: most categories; retail media and fast fulfilment drive visibility.
• Notes: price competitiveness and delivery SLAs impact Buy Box.

2) eBay UK

A powerhouse for refurbished, parts & accessories and collectibles; broadened appeal with fee changes for private sellers in 2024 (The Guardian).

3) Temu

One of 2025's UK traffic leaders, driven by ultra-competitive pricing and app-first engagement (Similarweb). Temu now counts around 13.1 million monthly active users in the UK, up 16.3% year-on-year, and roughly 12% of UK consumers say they have bought from it in the past year (Backlinko). After US tariff pressure pushed Temu to pivot toward Europe in 2025, it raised UK ad spending and made Europe its largest GMV region, so UK demand runs deep even though Temu's wallet share still trails its reach.

• Suits: value-led assortment across home, accessories and gadgets.
• Notes: cross-border logistics; set clear delivery/returns expectations, and note EU/UK scrutiny on product safety and compliance.

6) TikTok Shop UK

A fast-growing social commerce marketplace combining short video, live shopping and in-app checkout (TikTok Shop Seller Centre). The UK was TikTok Shop's first market and remains one of its most developed: roughly 200,000 UK small businesses now sell on it, and beauty, its strongest UK category, grew about 60% year-on-year (SQ Magazine). Globally, TikTok Shop GMV roughly doubled to around $66 billion in 2025, so UK sellers are competing for attention on a channel scaling faster than any other marketplace on this list.
