TL;DR:
- Octopus Energy launched the UK’s first V2G bundle in June 2026 — drivers are saving over £620 a year by selling electricity from their cars back to the grid
- V2G requires a compatible car, a bidirectional charger, and a V2G-capable tariff — all three need to align
- Compatible UK models in 2026: Kia EV9, Kia EV2, Hyundai IONIQ 5 Long Range, BYD Dolphin, Renault 5 E-Tech, VW ID.3/ID.4/ID.7
Most of the time, your electric car sits parked. For the average UK driver, that’s around 95% of the day. Vehicle-to-grid (V2G) technology turns that parked time into an income stream, letting your car export electricity to the grid when demand and prices are high, then recharge cheaply overnight when both are low.
It’s been technically possible for years. In June 2026, Octopus Energy and BYD made it commercially real for UK consumers with the launch of Britain’s first integrated V2G bundle.
How V2G Works
A standard EV charger moves electricity in one direction: from the grid into your car. A bidirectional charger, which V2G requires, can move electricity both ways. Your car’s battery becomes a local storage asset. The grid operator or your energy provider can call on it to export electricity when demand spikes — typically mid-morning and early evening — and recharge it when electricity is cheap (often overnight on an agile tariff).
From your point of view: you set the minimum charge you want in the battery (say, 40% for your commute) and the system handles the rest automatically. Your car charges and discharges in the background around your schedule. You get a monthly credit for the electricity exported.
The financial case rests on the spread between cheap overnight electricity and the higher rates paid for peak-time exports. On Octopus Agile, overnight electricity can be 5-8p/kWh. Peak-time export rates on the Power Pack tariff run significantly higher. Export your car’s battery at the right time and you’re effectively acting as a small grid battery — which is exactly how Octopus models it.
Octopus Power Pack: The UK’s First V2G Bundle
On 23 June 2026, Octopus Energy launched the Power Pack Bundle in partnership with BYD. The bundle combines:
- A BYD Dolphin (leased)
- A Wallbox Quasar 2 bidirectional home charger (installed)
- The Octopus Power Pack V2G tariff
Early users are saving more than £620 a year, according to Octopus CEO Greg Jackson, who called it a “game-changer.” The savings come partly from cheaper overnight charging and partly from export payments when the car discharges during peak periods.
The bundle model is significant because it solves the compatibility puzzle all at once. One of the barriers to V2G adoption has been the requirement for three separate components to align: a compatible car, a bidirectional charger certified for that car, and an energy tariff that pays you to export. Buying them separately is complex. The bundle handles it as a package.
Which Cars Support V2G in the UK in 2026
The V2G-capable vehicle list is growing but still limited. Confirmed bidirectional-capable models certified for UK V2G operation in 2026:
CHAdeMO standard (older but currently most widely certified):
- Nissan Leaf (older models via CHAdeMO port)
ISO 15118 / CCS-based bidirectional (the growing standard):
- Kia EV9
- Kia EV2
- Hyundai IONIQ 5 Long Range
- BYD Dolphin (via Octopus bundle)
- Renault 5 E-Tech
- Volkswagen ID.3, ID.4, ID.7
Tesla vehicles do not currently support V2G in the UK, though Vehicle-to-Home (V2H) is available in some markets via the Powerwall + Cybertruck combination. Tesla’s V2G roadmap for UK compatibility has not been confirmed.
V2G vs V2H: The Difference
V2G (Vehicle-to-Grid) exports electricity to the grid and typically earns you export payments. V2H (Vehicle-to-Home) powers your house from your car’s battery — no grid connection needed — useful during power cuts or for shifting self-generated solar. They’re not the same thing and don’t require the same setup.
Most UK interest in 2026 is V2H for resilience and V2G for income. If you have solar panels and want to maximise self-consumption, V2H is the play. If you want to generate income from your parked car, V2G is the route.
What You Need to Set It Up
A working V2G setup in the UK requires:
- A compatible car — from the list above. Check your specific model and year, as not all variants of a model may support bidirectional charging.
- A certified bidirectional charger — the Wallbox Quasar 2 supports CHAdeMO and CCS-based V2G. Ohme and Indra have also certified bidirectional units for specific vehicles.
- A V2G-capable tariff — currently Octopus Power Pack is the only widely available option. More are expected as the market develops.
- DNO approval — your distribution network operator (the company responsible for local grid infrastructure) may need to approve your setup. Octopus handles this as part of the bundle installation process.
The Honest Assessment
For the right setup — a compatible car, home ownership, an energy tariff that rewards smart charging — V2G is a genuinely compelling value proposition. £620 a year in savings is meaningful, and as grid flexibility services expand and more energy providers launch competitive V2G tariffs, the returns should improve.
The limits are real: the compatible vehicle list is still short, the charger installation cost is non-trivial (though bundled in the Octopus offer), and V2G savings depend heavily on how much you actually drive and how much battery headroom is available for export.
If you’re buying an EV in 2026 and thinking long-term, V2G compatibility is worth checking before you sign. The infrastructure is here and the tariffs exist. The market is early but functional.
