Top 25 E-commerce Sites in the UK 2021

Given that US companies gained an advantage thanks to the home market size and early growth in the UK, UK e-commerce is dominated by US platforms that operate in many segments, especially Amazon and eBay, which have by far the largest e-commerce shares in Great Britain. As the UK market is technologically advanced, with high penetration and high solvency, the competition for online spending is fierce. The wealth of the British people and their e-commerce habits make the UK one of the most sophisticated e-commerce markets in the world. They use both computers and mobile devices to shop online, acquiring a wide variety of goods and services online. Some key UK grocery and grocery retailers such as Tesco have managed to make their presence felt by selling online, even though Asda, owned by US retailer Walmart, is also a close competitor in this digital segment. Some traditional retailers focusing on specific categories, such as Argos for electronics and home appliances or B&Q and Screwfix with tools and hardware, are still able to seize market share.
