Not all electric cars support vehicle-to-grid charging. V2G requires a bidirectional onboard charger built into the car — a hardware component that most EVs on sale in the UK still do not have. This page lists every car confirmed as V2G compatible in the UK as of 2026, what charging standard each uses, and what hardware you need to activate V2G at home.
For the full explanation of how V2G works and what it can save you, see our V2G in the UK complete guide.
How to Check if Your EV Supports V2G
There are two things to check:
-
Does your car have a bidirectional onboard charger? This is a hardware feature — not all versions of a model will have it. Check your owner’s manual, the manufacturer’s website, or our list below.
-
Which charging protocol does it use? CCS (ISO 15118-20) is the modern European standard. CHAdeMO is older and used by legacy Nissan and Mitsubishi models. The protocol determines which home charger you need.
If both are confirmed, you can move on to choosing a charger and tariff. If your car is not on this list, it is not currently V2G compatible — though software updates are changing this for some VW Group models.

CCS vs CHAdeMO: What It Means for Your Charger Choice
The charging protocol your car uses determines which home charger is compatible.
CCS (ISO 15118-20) — the current European standard for AC and DC bidirectional charging. Compatible with the NexBlue Point 2 and Zaptec Go 2 (AC bidirectional, approximately £530 to £707). These are the right chargers for VW Group, Hyundai, Kia, and Renault bidirectional models.
CHAdeMO — the older DC bidirectional standard used by Nissan Leaf (older generations) and Mitsubishi Outlander PHEV. Compatible with the Wallbox Quasar v1 and Quasar 2. The Quasar 2 costs approximately £6,100 before installation.
If your car uses CCS, an AC bidirectional charger is the most cost-effective route to V2G. If your car uses CHAdeMO, you will need the Wallbox Quasar v1 (for Octopus Power Pack compatibility) or Quasar 2.
UK V2G Tariff Compatibility
Having a compatible car and charger is not enough on its own. You also need a V2G tariff. In the UK in 2026, only Octopus Power Pack exists.
Octopus Power Pack — currently compatible with:
- BYD Dolphin (V2G variant, via Octopus bundle with Zaptec Pro)
- Nissan Leaf (with Wallbox Quasar v1)
- Nissan e-NV200 (with Wallbox Quasar v1)
- Mitsubishi Outlander PHEV (with Wallbox Quasar v1)
For more details, see our Octopus V2G tariff guide.
Octopus has confirmed it is working on additional vehicle integrations. CCS-compatible models including those from VW Group and Hyundai are expected to be added as the market matures.
V2G Compatibility: What to Do Next
- Find your car in the list above and confirm whether it is V2G capable and which protocol it uses
- If compatible, choose the right home charger — see our best V2G charger guide
- Check whether your vehicle is currently supported by Octopus Power Pack
- Apply for Power Pack or wait for additional tariff options if your car is on the V2H-capable-but-tariff-pending list
- Allow up to 12 weeks for G99 DNO approval before your installation can begin exporting
Key Takeaways
- V2G requires a bidirectional onboard charger — a hardware feature that most UK EVs still lack in 2026
- CCS (ISO 15118-20) is the modern standard; CHAdeMO is the legacy standard used by older Nissan and Mitsubishi models
- The Kia EV9 has the largest V2G-capable battery at 99.8 kWh; the Kia EV2 and Renault 5 E-Tech offer the most affordable entry points
- VW Group ID models (77 kWh) gained V2G capability via a Software 3.5 OTA update
- The Octopus Power Pack tariff currently supports four vehicle types; more integrations are expected
- Tesla models are not compatible with V2G
Frequently Asked Questions
My VW ID.4 is on the list — what do I need to do to enable V2G? You need the 77 kWh battery variant, Software 3.5 or later installed, and a compatible bidirectional home charger (NexBlue Point 2 or Zaptec Go 2). You will also need G99 DNO approval and a V2G tariff. Octopus has not yet confirmed ID.4 on the Power Pack list — check directly with Octopus before purchasing hardware.
Can I use V2H with my car while waiting for V2G tariff compatibility? Yes. If your car is bidirectional-capable and you have a compatible home charger, you can use V2H (powering your home from your battery) without a V2G tariff or G99 approval. V2G is the additional step that involves grid export.
Why is the IONIQ 5 Standard Range not on the V2G list? The Standard Range (58 kWh) IONIQ 5 does not have the same bidirectional hardware configuration as the Long Range (77.4 kWh) version. Hyundai has confirmed bidirectional capability for the Long Range; the Standard Range is not confirmed.
Is the BYD Seal or BYD Atto 3 V2G compatible? No. The BYD Dolphin in its standard configuration supports V2L only. The Dolphin V2G variant is a specific version available exclusively as part of the Octopus Power Pack bundle. The BYD Seal and Atto 3 are V2L capable but not V2G or V2H compatible in the UK at time of writing.
How often does this compatibility list change? It is updated as manufacturer announcements, OTA updates, and tariff additions are confirmed. The market is moving quickly in 2026 — expect significant additions to the V2H/V2G compatibility roster over the next 12 to 18 months as ISO 15118-20 becomes standard across more mainstream vehicles.
