V2G cars in the UK: what's on sale now and what's coming
There's one vehicle-to-grid setup you can buy in the UK at the moment, a BYD Dolphin with a Zaptec Pro charger on Octopus Power Pack, and a lot of what else is advertised is US-only, a pilot or announced for later.

If you want V2G in the UK today, the Octopus Power Pack bundle with a BYD Dolphin is the only live option. Mercedes, Nissan and Renault have all announced UK V2G for 2026, and Mercedes has launched in Germany, but we wouldn't pick a car on the strength of that until the UK offer is actually on sale.
Power Pack sits on top of an Octopus import tariff, so you need to be an Octopus customer first. If you're not with them yet you join on a standard tariff and move across once they've connected to your smart meter, which Octopus says takes around 14 days.
V2G, V2H and V2L
- V2G (vehicle-to-grid): the car sends stored energy back to the grid and you can be paid for it.
- V2H (vehicle-to-home): the car powers your house through a bidirectional charger, at peak times or in a power cut, without exporting to the grid.
- V2L (vehicle-to-load): the car powers individual appliances through a socket or adapter, with no home charger needed.
A lot of cars advertised as “bidirectional” only offer V2L in the UK, which is handy for powering equipment away from home but does nothing for your energy bill.
What you can buy now
Octopus Power Pack with a BYD Dolphin
Power Pack is an add-on to your normal import tariff where Octopus schedules when the car charges and exports, and credits back what you paid for charging as measured by the charger. It doesn't have a standing charge of its own.
Octopus's own figures put the saving at about £620 a year compared with Flexible Octopus, or £161 compared with Intelligent Octopus Go. Those are Octopus's figures rather than ours, and they assume:
- the car is plugged in 12 hours a day, 20 days a month
- you charge less than 210 kWh a month
- you set a minimum charge level below 30%
- you're not on Agile, Tracker or one of the Intelligent tariffs, as it can't be combined with them
There's also a car bundle, a V2G-enabled BYD Dolphin on a 24, 36 or 48-month contract with charging included up to 12,000 miles a year, and anything above that billed at the Intelligent Octopus Go off-peak rate (8p/kWh). Servicing and the Zaptec Pro installation are included, you need a single-phase supply and a half-hourly smart meter, and Octopus says delivery takes 2 to 4 months. It was “under £300 a month” at launch in June 2025, and Octopus EV's bundle page now asks you to get a quote rather than publishing a price.
Where each carmaker stands in the UK
| Car | UK status | What it needs |
|---|---|---|
| BYD Dolphin (V2G-enabled) | V2G live | Zaptec Pro, Octopus Power Pack, G99 approval, half-hourly smart meter |
| Kia EV9, EV6, EV3 | V2L only in the UK | n/a |
| Volkswagen ID range | V2L now, V2H and V2G pilots only | Software 6, or software 3.5 with a 77 kWh or bigger battery |
| Mercedes GLC electric and electric C-Class | V2G launched in Germany in October 2026; UK announced but we haven't found a UK launch | Mobility House DC wallbox, MB.CHARGE Home Pro |
| Nissan (new AC system) | Announced “from 2026, UK first”, model not named | Enovates charger |
| Renault 5, 4, Megane, Scenic, Alpine A290 | UK planned for 2026, “not yet available” | Mobilize Power Box Verso |
| Volvo EX60 and later | Staggered rollout, UK not confirmed | Volvo wallbox and home energy system |
| Older Nissan Leaf (CHAdeMO) | Trials only, no retail offer | CHAdeMO bidirectional charger |
Kia and the Wallbox Quasar 2
The Kia EV9 with a Wallbox Quasar 2 charger gets asked about a lot, but Kia UK says its cars only support V2L in the UK at the moment. The EV9 and Quasar 2 V2H package is a US offer, and in the UK the Quasar 2 was pre-registration only as of April 2026 with no UK price.
What's coming
- Mercedes, Nissan and Renault all have UK V2G announced for 2026. Mercedes started its V2G offer in Germany in October 2026 with the electric GLC and C-Class, and none of the three had a UK offer on sale when we last checked on 22 October 2026.
- ISO 15118-20 Amendment 1, the standard covering AC V2G, was published on 17 July 2026, which should make AC bidirectional chargers easier to certify.
- The government's Clean Flexibility Roadmap (13 July 2026) commits to a consultation on charger communication standards for V2X by the end of 2026 and a V2X technical specification in 2027.
Things to check
- Grid approval. V2G counts as generation, so your network operator has to approve it under G99. Octopus quotes 10 to 45 working days on one page and up to 12 weeks on another. There's a simpler notify-only route, but only at 3.68 kW per phase or less with a type-tested charger on the ENA register.
- Battery warranty. Volvo UK says bidirectional use shouldn't significantly affect battery life and the warranty is unaffected, whereas Volkswagen (in Germany, 2023) limited discharging to 10,000 kWh or 4,000 hours and not below 20% charge. Octopus's Power Pack page doesn't mention warranty, so check with the carmaker before you commit.
- Charger cost. We couldn't find an official UK price for a standalone bidirectional home charger.
Where that leaves you
If you want V2G now and a BYD Dolphin suits you, the Power Pack bundle is the only route and the conditions are worth reading carefully. If you're replacing your car in the next year and V2G matters to you, we'd wait until the UK offer is live before paying for it. Until then a standard EV on Octopus Go gets you cheap overnight charging without any of the grid approvals.
Common questions
Which cars can do V2G in the UK now?
The only live UK V2G setup is the BYD Dolphin with a Zaptec Pro charger on Octopus Power Pack. Mercedes, Nissan and Renault have announced V2G for the UK in 2026.
What is the difference between V2G, V2H and V2L?
V2G sends the car's stored energy back to the grid and you can be paid for it. V2H powers your home through a bidirectional charger without exporting. V2L powers appliances through a socket or adapter and does nothing for your energy bills.
Does V2G need approval from the network operator?
Yes. V2G counts as generation and needs G99 approval, which Octopus quotes at 10 to 45 working days on one page and up to 12 weeks on another. A notify-only route is available at 3.68 kW per phase or less with a type-tested charger on the ENA register.
