So Energy Launches 'SO EV' – One of The UK’s Most Competitive Home EV Charging Tariffs

So Energy, one of the UK’s leading renewable energy providers committed to a greener future, is excited to announce the launch of So EV, a dedicated tariff designed specifically for electric vehicle (EV) drivers who charge their cars at home.

With the number of EVs on UK roads continuing to grow - as highlighted in to So Energy’s May 2025 market tracker research¹, which found that 8% currently have an EV and a further 33% expect to own one within the next 2 years – So EV addresses this rising demand and offers drivers an affordable, sustainable, and smart solution for overnight charging.  

The same research also revealed that 79% of consumers are interested in energy tariffs tailored to their individual needs. This insight underpins the launch of So EV, reflecting So Energy’s commitment to developing simple, flexible products that match customers’ lifestyles and support the UK’s shift to cleaner transport.  

The tariff includes an off-peak electricity rate of just 6.5p per kWh between 12am and 5am, making it one of the most competitive EV charging tariffs currently on the market.

So EV enables EV owners to significantly 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 provides a reliable way for customers to maximise their EV investment and save.

Key Benefits of So EV:

• Low overnight rate of 6.5p/kWh (12am–5am) – perfect for scheduled home charging

• 100% renewable electricity – helping EV drivers further reduce their carbon footprint

• Reduces strain on the national grid – by shifting demand to off-peak hours

• Fixed 12-month tariff – offering price stability and peace of mind

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.”
