Arriva North West became responsible for the management of Arriva Cymru Ltd from 25 February 2002, and to reflect this, the name for this division of Arriva became Arriva North West and Wales. Arriva North West and Wales expanded further when the Crewe, Macclesfield and Winsford depots of Arriva Midlands North Ltd were transferred to it on 1 February 2003 and this has enabled Arriva North West and Wales to assume control of much of what was Crosville Motor Services with the exception of the Rock Ferry - Birkenhead, Chester and Ellesmere Port (now closed) depots which are part of First Chester & The Wirral.
