New partnership combines So Energy's new low-cost renewable EV tariff with Zaptec's premium charging technology to help customers get more from home energy.
London, UK, 8 July 2026 - Zaptec, Europe's market-leading AC home charging brand, and So Energy, a renewable energy supplier helping customers use greener energy more intelligently, today announced a new UK partnership designed to help electric vehicle (EV) drivers get more from charging at home.
By combining So EV, So Energy's new low-cost renewable EV tariff, with Zaptec's premium charging technology, the partnership gives customers a simple way to reduce charging costs, use 100% renewable electricity and prepare for a smarter, more connected energy future.
Analysis from LCP Delta shows around three-quarters of UK EV drivers already use dedicated EV tariffs, one of the highest adoption rates in Europe. As EV ownership matures, the opportunity is shifting from simply getting people behind the wheel of an EV to helping them get more value from charging at home through smarter tariffs, cleaner energy, and intelligent charging technology.
Helping people get more from home energy
The So EV tariff enables customers to charge their electric vehicle for 7.5p per kWh between midnight and 5am using 100% renewable electricity.
For drivers able to charge at home, shifting charging into off-peak hours can significantly reduce EV running costs while making better use of renewable energy generation. In So Energy's example, charging a Tesla Model Y overnight on So EV costs around 1.7p per mile, compared with 17.6p per mile using a typical public rapid charger. Public charging remains an essential part of the UK's charging infrastructure, while smart home charging offers many drivers an opportunity to significantly reduce day-to-day charging costs.
To help customers make the most of So EV, So Energy has chosen Zaptec as its preferred premium home charging partner.
"The next phase of the EV transition isn't simply about getting more people driving electric. It's about helping people get more from home energy. Drivers increasingly expect their car, charger and energy tariff to work together as one connected experience, and that's where the market is heading.
Our partnership with So Energy brings together low-cost renewable energy and premium charging technology designed to evolve alongside the UK's changing energy system, helping customers make smarter energy choices today while preparing for tomorrow's connected energy future."
