Fast-growing EV charging operator Source has signed a partnership with Siemens eMobility and Evolt Charging for a unified maintenance model that will give fleets confidence its hubs will be up and running when they need them.

The agreement will deliver an integrated operational and maintenance model across the growing Source UK and Ireland charging infrastructure. The ultra-rapid electric vehicle charging network, launched in 2024 as a joint venture between SSE and TotalEnergies, is powering up toward 300 hubs by 2030.

As part of the collaboration, Siemens eMobility will supply high-performance charging hardware across an increasing number of Source sites. Evolt Charging will provide the field engineering capability to install, commission and maintain that hardware at scale, with engineers deployed across Scotland, England, Wales and the Republic of Ireland.

At the heart of the agreement is a single point of contact for all maintenance and repair activity across Source’s estate regardless of charger type or location – backing up the charging network’s 99%+ uptime ambition.

This will draw on Evolt Charging’s specialist field engineering capability, with its team already trained and accredited on Siemens eMobility equipment. As Source continues to add sites, Evolt Charging is expanding its pool of Siemens-trained engineers to keep pace.

Source opened its first ultra-rapid charging site in Edinburgh in May 2025 and already operates around 40 ultra-rapid charging hubs across the UK and Ireland. All hubs feature chargers of at least 150kW, with higher-powered options available across the network, all powered by renewable energy. Most EV drivers can add approximately 100 miles of range in around 15 minutes.

Deepa Chandrasekaran, managing director at Source, said the new collaboration delivers a model that means customers can rely on the network wherever they are.

“As we grow, maintaining that reliability is what will set Source apart. EV drivers and fleet operators need to know that when they pull up to one of our hubs, it will work. Partnerships such as this are how we make that promise credible.”

Stephen Wood, head of Siemens eMobility UK, said the partnership would support Source in setting high standards for uptime and customer confidence as their network continues to grow

“Our collaboration with Source EV and Evolt Charging is built for scale and designed to deliver high uptime, reliable customer experience and operational excellence. Backed by a strong framework agreement, it demonstrates how strong alignment can accelerate the delivery of reliable, ultra-rapid charging that EV drivers can depend on.”
