Coffee-giant Costa has installed the 5,000th self-serve Costa Express coffee bar.

Installed in locations such as convenience stores, forecourts, airports and train stations, the milestone puts Costa on track to hit its target of 8,000 machines by 2020.

Costa Express has grown at an average of 70 new machines each month following the £59.9m acquisition of Coffee Nation by Whitbread in 2011.

“Costa Express has enjoyed tremendous growth from 877 machines in 2011 to 5,000 today” said Costa Express MD Murray McGowan.

“We have always been confident that combining our superior technology with the same quality coffee and fresh milk found on the high-street through Costa, the nation’s favourite coffee shop, we would be able to deliver an unbeatable coffee experience to on-the-go customers.”

The buyout has also allowed Costa Express to expand further into previously untapped European markets such as the Netherlands, Czech Republic, Poland and Denmark where it now has 440 machines.

“This milestone 5000th install proves the consumer demand we’re delighted by the results from multiple international pilots that demonstrate the appeal of the brand in overseas markets away from the mother-brand, showcasing the potential for growth.” said McGowan.
