Big four no more: What next for UK grocery as Aldi overtakes Morrisons?


After years of incremental growth, Aldi has finally overtaken Morrisons in UK grocery market share and ended decades of the ‘big four’. What does this seismic moment mean for grocery in the long term?

For decades, the UK grocery market has been dominated by four big players: Tesco; Sainsbury’s; Asda; and Morrisons. 

But in a watershed moment for the sector, that stranglehold on the market has been broken after Aldi’s market share overtook that of Morrisons for the first time. In the 12 weeks to September 4, Aldi sales grew 18.7%, taking its market share to 9.3%, usurping the 9.1% occupied by Morrisons.
