The rest of the top 10 online stores
The rest of the top 10 is made up of more supermarket chains, as well as international players like Apple and Amazon. The United Kingdom is also known for online stores such as Asos, Secret Sales and Missguided. Due to a massive rise in inflation in the country since 2022, many online stores saw their sales volumes decline. This is why Asos, after being in the top 10 for many years, is not included anymore by 2023.
Local sellers have large market share
The ecommerce market in the United Kingdom is dominated by local omnichannel sellers. Because of their established reputation with their brick-and-mortar stores, they were able to perform well online when launching their online channels.
This can make it difficult for online sellers to gain a customer base in the country. However, by being active on online marketplaces like Amazon or Etsy, they automatically reach a larger audience.
