One cannot generalise, as it depends on the operator and the depot allocation.In my experience there are not "double deck routes" and "single deck routes", though some routes are mostly double-deck and others mostly single-deck. Still others are a complete mix.
In Eastern Cheshire, nearly all buses are single deck, particularly since D&G took over most scheduled services. Previously, Arriva did have a few double deck buses, but one came to grief at a low bridge close to Macclesfield Station a few years ago.
In the Altrincham area, Metroline (on behalf of the Bee Network) only operate single deck buses from their Wythenshawe garage, as did Arriva before them. Double deck buses are used on schools services, and also route 11 operated by Stagecoach.
Frankly, few routes, except high frequency ones in major conurbations, now warrant the use of double deck buses, and they are a risk/liability in places with low bridges.
