TikTok Shop Is Becoming A Key Channel For UK E-commerce

We recently reported on TikTok Shop’s record-breaking Black Friday in the UK, where sales peaked at 27 items per second. That moment was not an outlier — it was a signal of a broader shift. Now, major retailers and more than 200,000 UK businesses are treating TikTok not just as a marketing channel but as a core part of their e-commerce strategy.

From Entertainment To Shopping Without Leaving The App

TikTok has quietly built a strong position in online retail. Its service, TikTok Shop, launched in the UK in 2021 and now hosts more than 200,000 small and medium-sized businesses, alongside an increasing number of major brands.

Retailers such as Marks & Spencer, Samsung, QVC, Clarks and supermarket chain Sainsbury’s are already active on the platform, selling products directly inside the app.

The model is simple: brands can tag products in short videos or livestreams, allowing users to buy instantly without being redirected elsewhere. Products can be promoted either by the brand itself or by influencers using affiliate links. Once a sale is made, the revenue is split between TikTok, the seller and any creator involved.

Numbers That Get Big Retail’s Attention

TikTok Shop recorded its biggest UK sales day ever on Black Friday, when 27 items were sold every second. Across the Black Friday and Cyber Monday period, sales rose by 50% compared with the previous year.

Sainsbury’s was one of the first supermarkets to join the platform. Its Christmas pyjamas sold out in under a week, after a sponsored collaboration with influencer Rachel Spicer, which generated 6.6 million views.

Marks & Spencer has also seen strong results from TikTok Shop livestreams, with one recent broadcast attracting 260,000 viewers and generating sales at a rate of roughly one item every 30 seconds.

Opportunity – And Pressure – For Smaller Brands

For small businesses, TikTok has become a way to expand reach at a time when visibility in search engines is becoming harder to achieve. London-based jewellery brand L’ERA expects to generate around £145,000 in revenue via TikTok this year, with some customers placing single orders worth more than £1,400.

Live shopping plays a key role in that success. The brand typically runs three three-hour livestreams each week, doubling that frequency during peak periods such as Black Friday and Christmas.

At the same time, experts warn that the model has downsides. While TikTok Shop can be a gamechanger for sales and exposure, it may also encourage aggressive price competition, push small businesses to produce constant content, and shift focus away from long-term brand building toward chasing trends.

For e-commerce players, TikTok is proving to be a powerful sales channel — but one that comes with real costs and strategic trade-offs.
