Glasgow and Salisbury have ushered in the 2020s with small pioneering batches of zero-emission battery electric single-deckers that at least one of those cities hopes will be the norm in 10 years’ time.
Electrification of the UK’s bus fleets — especially outside London — may still seem to be painfully slow and the numbers of vehicles involved almost tokenistic, but even in places where single figures of zero-emission vehicles are entering service, the ambition to operate much greater numbers is palpable.

The first two such projects in 2020 — in Glasgow and Salisbury — are cases in point. First Bus put two 10.8m BYD/Alexander Dennis Enviro200EV single-deckers into service in January on a meandering hourly service through some northern districts of Glasgow, a city whose politicians are talking of a move to 100% zero-emission vehicles within the next 10 years.
