V2G vs V2H — what’s the difference?
- Vehicle-to-Grid (V2G): V2G charging lets a compatible EV battery send electricity back to the public grid through a bidirectional EV charger. Depending on your EV, charger, supplier and tariff, you may earn money from exported electricity or reduce energy costs. You need a compatible EV, bidirectional charger and supported V2G service or tariff.
- Vehicle-to-Home (V2H): V2H uses bidirectional EV charging to send power from your EV battery into your home. This can reduce electricity imported from the grid. It can also use solar energy stored in your car. Unlike V2G charging, V2H does not export electricity to the public grid.
Compatible EVs and bidirectional charging in 2026
Not every EV supports bidirectional charging. Compatibility depends on the EV model, battery, software, connector, charger and UK service. A car may support V2X technology without offering V2G or V2H to every owner.
- Nissan LEAF**: Compatible LEAF models support V2X use, including V2H and V2G, with the right hardware and CHAdeMO connection. Nissan confirms charging and discharging capability for compatible vehicles.
- Mitsubishi Outlander PHEV: Some Outlander PHEV models support V2H with a compatible CHAdeMO bidirectional charging system.
- Volkswagen ID models: Volkswagen supports bidirectional charging on eligible ID vehicles. Availability depends on the model, battery size and software version. Many ID models with a 77kWh battery or larger can use the technology, while V2G applications continue to develop.
- Tesla: Tesla is developing Vehicle-to-Home (V2H) capability. Availability depends on the vehicle, hardware and market. Tesla’s UK information currently focuses on bidirectional home energy use rather than a general V2G service across its EV range.
Is V2G or V2H worth it right now?
For UK homeowners in 2026, the costs depend heavily on your existing EV and charging hardware. Bidirectional EV chargers usually cost more than standard home EV chargers. Availability also remains limited.
Several factors affect whether V2G charging or V2H makes financial sense. These include EV compatibility, software, charger availability and energy service support.
For many households, smart EV charging with a time-of-use electricity tariff remains simpler. Overnight charging can also reduce electricity costs. Homes with solar panels should consider how solar self-consumption, home battery storage and EV charging work together.
A home battery stores energy without relying on your car being connected. By contrast, V2H can use the larger battery in your electric car when the vehicle is plugged in.
