Costa is the UK’s biggest coffee chain according to venues registered with local councils for food hygiene inspections. There were 2,661 Costa outlets across the country as of February 2022.
Looking at the national picture, the City of London is probably the easiest place to get a cup of coffee with a Costa, Caffe Nero, Greggs, Pret or Starbucks for every 108 people who live in the area. This is likely because while only 10,938 people live in the Square Mile, it’s visited by many more workers and tourists.
This particular area has 16 Costas, six Greggs, 15 Starbucks, 14 Caffe Neros, and 50 Prets - one in eight of the company’s entire UK operation. The City of London is also the nation’s Pret capital.
