How much did EV owners save during the Crowdflex home energy trial?

EV owners participating in the Crowdflex home energy trial saved a combined total of £750,000 over 13 months.

What was the main goal of the Crowdflex home energy trial?

The Crowdflex trial studied how households could help increase flexibility in the electricity grid by shifting when energy is used, while also helping grid demand.

Do Crowdflex trials impact EV battery health?

No, Crowdflex trials do not impact EV battery health as they only shift charging times and utilize slower domestic charging rates (max 7.4kW), unlike rapid public charging.

UK EV Charging Trial Saves Drivers £750K

EV owners participating in the 'Crowdflex' home energy trial have collectively saved £750,000 over a 13-month period. This initiative studied how households could enhance grid flexibility by shifting their energy consumption. The trial, which began in May 2024 and concluded in September 2025, engaged 20,000 customers, making it the largest UK home EV charging company participation in a flexibility trial. Participants flexed nearly 150MW of electricity.

Drivers were incentivized to plug in their electric vehicles at home more frequently and for longer durations. This allowed for intelligent management of charging times, enabling customers to benefit from cheaper electricity rates and helping the grid manage demand, particularly during peak times and when renewable energy is abundant. Ohme, the UK's largest home charging company, reported a 40% increase in plug-in rates among participants compared to a control group.
