EKO Bulgaria EAD has a chain of 91 petrol stations under the brand EKO on the territory of the Republic of Bulgaria. The activities of the company include the retail and wholesale trade of petroleum products and lubricants under the EKO brand. In 2014, EKO Bulgaria EAD launched the “EKO Guarantee” program, where independent licensed inspectors make regular, unexpected checks at its service stations. As a result, all EKO service stations are certified by a licensed third party.
