The main fleet of Arriva Malta was formed of 172 new King Long buses. These were supported on high-density routes by 68 former Arriva London Mercedes-Benz O530G Citaro articulated buses. Ten hybrid Optare Solos and two Bluebird mini-buses for use in the city of Valletta were also purchased. An assortment of the newest buses from the former owner/driver pre-July 2011 operation were also acquired and refurbished to bring them broadly into line with the rest of the fleet. This included the fitting of air conditioning and CCTV equipment and rebranding into standard Arriva livery for daily use alongside the main fleet. These included buses built by SCARNIF, MCV, BMC, King Long and Saracakis among others, with the main common factor being that they are all fully automatic and low floor designs.
