Renewable energy provider So Energy has launched So EV, a dedicated tariff designed for electric vehicle (EV) drivers who charge their cars at home.
So Energy’s May 2025 market tracker research found that 8% of drivers currently have an EV, and a further 33% expect to own one within the next two years.
So EV aims to address this rising demand, and offer drivers an affordable, sustainable, and smart solution for overnight charging.
The research also revealed that 79% of consumers are interested in energy tariffs tailored to their individual needs.
The tariff includes an off-peak electricity rate of just 6.5p per kWh between 12am and 5am, So Energy have said this is one of the most competitive EV charging tariffs currently on the market.
So EV enables EV owners to reduce their charging costs by scheduling their vehicle charging during off-peak hours.
With energy prices fluctuating and public charging costs remaining high, up to 92% more expensive than charging at home, this tariff was designed to provide a reliable way for customers to maximise their EV investment and save.
Some elements of So Energy’s tariff include, low overnight rate of 6.5p/kWh between 12am-5am, 100% renewable electricity, it can reduce strain on the national grid and create stability through a fixed 12-month tariff.
To be eligible for So EV, customers must have an electric or plug-in hybrid vehicle, a home EV charger, and a smart meter providing half-hourly usage data and the tariff is available to both new and existing So Energy customers.
Michelle Little, head of propositions, said: “At So Energy we’re delighted to provide our customers who are electric vehicle drivers with our simple, highly competitive So EV tariff.
“EV drivers with a smart meter can now charge their cars overnight at the low rate of 6.5p per kWh without a complicated set up or separate plan.
“We’ve created this smart tariff with simplicity and savings in mind, helping them reduce both their carbon footprint and energy bills.”
