Best EV Tariff UK 2025: Compare Cheapest Electric Car Charging Rates

The search for the best EV tariff in the UK has never been more important. As electric vehicle adoption accelerates, the cost of charging at home can vary dramatically depending on the energy plan you choose. The right tariff could slash your annual charging bill by hundreds of pounds while also offering greener energy and smarter charging solutions. This is why comparing different suppliers and their rates in 2025 is essential for every EV owner.

In the UK, several energy providers now offer dedicated EV tariffs with cheaper off-peak rates, typically overnight when national energy demand is lower. This is ideal for those who can schedule charging during these hours, as the cost per kWh can drop to as little as 7p. Whether you’re with Octopus Energy, British Gas, EDF, OVO, E.ON Next, Scottish Power, Utility Warehouse, or Power NI, understanding the differences between plans can help you identify the best EV tariff for your lifestyle and driving habits.

What is an EV tariff and how does it work

An EV tariff is a specialist electricity plan tailored to the needs of electric vehicle drivers. Unlike a standard home energy tariff, it offers reduced rates during specific time periods, often late at night. This encourages charging when the grid is under less strain, making it both cost-effective for the customer and efficient for the energy network. Some tariffs also include benefits like renewable electricity or integration with smart charging technology.

To make use of the best EV tariff, most households will require a smart meter. This technology records when electricity is used, allowing your supplier to apply cheaper off-peak rates during the designated charging hours. For example, Octopus Energy’s Intelligent Octopus Go and E.ON Next Drive both use this approach, enabling drivers to benefit from low-cost electricity while keeping their vehicles fully charged and ready for the day ahead.

EV tariff comparison UK 2025 – who offers the best deals

In 2025, Octopus Energy continues to lead the pack with its Intelligent Octopus Go tariff, which offers overnight charging at just 7.5p/kWh during a six-hour window. This makes it possible to fill a typical 60kWh EV battery for less than £5. British Gas competes with its Electric Driver tariff, which provides a low 7.9p/kWh rate between midnight and 5am, ideal for those who have a regular charging schedule.

E.ON Next’s Next Drive tariff is another strong contender for the best EV tariff, with competitive overnight rates and fixed pricing for peace of mind. EDF’s GoElectric 35 plan offers 9p/kWh off-peak rates and 100% renewable electricity. OVO Energy’s Charge Anytime add-on is especially popular because it provides a low rate of around 7p/kWh whenever the vehicle is plugged in, regardless of the time. Scottish Power, Utility Warehouse, and Power NI also offer region-specific deals, ensuring there is a suitable EV tariff option for almost every UK driver.

How to choose the best EV tariff for your needs

Finding the best EV tariff depends on your individual circumstances. Drivers who primarily charge overnight should focus on plans with the lowest off-peak rates, while those who need flexibility might prefer a tariff with a consistently low rate across the day. It’s important to calculate your typical monthly mileage, battery size, and charging frequency to estimate potential savings.

An EV tariff comparison can reveal differences not only in price but also in contract length, green energy credentials, and customer service ratings. For example, if sustainability is a priority, you might choose EDF’s or Octopus Energy’s 100% renewable plans. On the other hand, if you already use a supplier like British Gas for other services, bundling an EV tariff could make switching easier and cheaper.

Cheapest EV tariff options – real cost breakdown

The cheapest EV tariff can significantly reduce your running costs. To illustrate, charging a 60kWh battery at an off-peak rate of 7p/kWh would cost £4.20, while the same charge on a standard rate of 30p/kWh could cost £18 or more. Over a year, this could save frequent drivers hundreds of pounds, making the choice of tariff crucial.

Octopus Energy, OVO Energy, and E.ON Next currently offer some of the lowest overnight rates in the UK. If your driving habits align with their off-peak times, you can achieve maximum savings without changing your charging routine. Many suppliers also provide mobile apps that allow you to monitor your energy usage and schedule charging sessions, ensuring you always take full advantage of the best EV tariff rates.

Future of EV tariffs in the UK

Looking ahead, the best EV tariff options are expected to become even more competitive. As more people transition to electric vehicles, energy suppliers will likely introduce innovative plans with longer off-peak windows and integration with renewable energy sources. The expansion of vehicle-to-grid (V2G) technology could also allow EV owners to sell excess energy back to the grid, potentially offsetting charging costs entirely.

Government policies supporting clean transport and smart energy infrastructure will further shape the EV tariff market. This means that in the coming years, choosing the best EV tariff won’t just be about saving money—it will also be about playing an active role in the UK’s journey to net-zero emissions.

Conclusion – making the switch to the best EV tariff in 2025

Switching to the best EV tariff can transform the cost of running your electric vehicle. With options from leading suppliers such as Octopus Energy, British Gas, EDF, OVO, E.ON Next, Scottish Power, Utility Warehouse, and Power NI, there’s no shortage of competitive deals in 2025. By choosing a tariff that matches your charging habits and energy values, you can enjoy both financial savings and environmental benefits.

Whether your priority is the cheapest EV tariff, the most flexible charging window, or 100% renewable energy, there has never been a better time to explore your options. The right choice will ensure you drive into the future fully charged, both literally and financially.
