The Yutong E12 is popular in the Nordic countries. The city of Roskilde in Denmark received its first Yutong buses in 2019, replacing its diesel bus fleet with 20 E12s. The cities of Copenhagen and Odense, as well as Bergen in Denmark, who all have bus services run by Keolis soon followed, with each city receiving deliveries of Yutong E12s throughout 2020 and 2021. 14 Yutong E12s were also delivered for service in Iceland's capital city of Reykjavik in November 2018, while 35 E12s were delivered to both the Finnish capital of Helsinki and neighbouring Kerava in 2019.

The initial incident occurred on June 16, 2023, and, according to the driver's statement, was a result of unresponsive brakes. No casualties were reported in this occurrence. The second incident took place on October 3, 2023, when the bus inexplicably breached the guardrail of a viaduct and plummeted 15 meters. This accident resulted in 21 fatalities and 15 injuries.

Yutong E10s and E12s, as well as other Yutong products, have been sold in the United Kingdom through the Pelican Bus dealership in Castleford since 2018, where a new showroom and workshop for the final assembly and technical support of Yutong buses and coaches opened in January 2023. The company is also partnered with battery supplier Zenobe, who assist in installing charging infrastructure and providing new batteries for electric bus operators. The first ten Yutong E10s ordered for the United Kingdom market entered service with Go North East in November 2020. These Yutongs were branded as Voltra buses for services on routes 53 and 54 between Newcastle upon Tyne and Gateshead, with the launch preceded by a major marketing campaign by Go North East, and were delivered with high-specification interiors and exterior LED lighting designed by Best Impressions.
