London’s First All-Electric Double-Decker Bus Enters Service
BYD’s battery-powered double-decker begins operations in London, promising up to 190 miles of zero-emission range on a single charge and overnight recharging.
The first fully electric double-decker bus built by BYD has started service on London’s streets, marking a step forward in the capital’s efforts to cut air pollution from public transport. The Chinese manufacturer delivered the 10.2-metre bus as part of an initial fleet of five, all set to join regular routes in the city.
London already runs a number of low-emission and hybrid buses, but until now had not fielded a double-decker powered entirely by batteries. BYD developed the vehicle in response to a challenge from city officials, who doubted whether an electric double-decker could handle the city’s demanding routes. The bus uses iron phosphate batteries with a total capacity of 345 kWh, giving it a quoted range of up to 190 miles under the Standardised On-Road Test (SORT) cycle. That covers most daily urban duties without intermediate charging.
Battery and charging details
BYD’s system allows the bus to be recharged in four hours, making overnight charging on off-peak electricity feasible for operators. The company has worked with London authorities to install compatible fast-charging infrastructure and to train drivers for the new technology. This approach is intended to minimise disruption to existing schedules while maximising the environmental benefit.
Impact on London’s bus fleet
With five vehicles in the initial batch, the rollout is modest in the context of London’s thousands-strong bus fleet. However, the launch signals intent from both Transport for London and BYD to push zero-emission technology into mainstream service. If the buses prove reliable and cost-effective, further orders could follow as the city seeks to meet air quality targets.
The move builds on previous low-emission initiatives in London and mirrors growing interest in battery-powered buses elsewhere. Other manufacturers, including European and North American firms, have also begun to expand their electric bus offerings, as covered inVW and New Flyer Expand Electric Bus Offerings as Segment Grows.
What it means for operators and passengers
For operators, the main change is the shift to overnight charging and the need for new maintenance skills. For passengers, the electric double-decker promises a quieter ride and reduced local emissions, with the familiar two-level format retained. The bus’s range and charging capabilities are designed to fit existing urban schedules without major compromise.
