Best Bidirectional (V2H and V2G) Home Chargers in the UK
On this page

Bidirectional home chargers let your electric car do more than charge: they can send power back to your home (V2H) or to the National Grid (V2G), turning your EV's battery into a large home energy store. The technology is real and available in the UK, but it is still developing quickly, so the landscape of compatible chargers and vehicles is changing fast. If you are serious about exploring bidirectional charging, this guide explains what to look for and what to check before you buy. For standard one-way charging needs, browse EV charging cables by car while you weigh up whether bidirectional is right for you.
| Charger type | What it does | Key requirement | Typical use case |
|---|---|---|---|
| V2H charger | Feeds power from EV battery to home circuits | Compatible EV + home integration wiring | Self-consumption, backup power |
| V2G charger | Exports power from EV battery to the National Grid | Compatible EV + smart export tariff + DNO approval | Grid services, tariff arbitrage |
| Standard wallbox | Charges the EV only (one direction) | Type 2 socket or tethered cable | Everyday home charging |
What makes a charger "bidirectional"?
A standard home wallbox pushes AC electricity into your car's onboard charger, which converts it to DC for the battery. A bidirectional charger runs that process in reverse, converting DC from the battery back to AC for your home or the grid. This requires specialised hardware in both the wallbox and the car, which is why not all EVs support it and why these units currently cost significantly more than a standard wallbox. The two most relevant connection standards in the UK are CCS (used by most modern European-brand EVs) and CHAdeMO (used by the Nissan Leaf and a handful of other models). Always verify which standard your car uses before choosing a charger.
Which charger brands are available in the UK?
The UK market for bidirectional home chargers is small but growing. Names that appear regularly include Wallbox (the Quasar 2, which uses CHAdeMO), Indra (with V2H compatibility across a range of vehicles), and Zaptec, alongside emerging CCS-compatible units. New entrants appear regularly, so treat any shortlist as a starting point and check manufacturer websites for current UK availability and vehicle compatibility lists. Installation must be carried out by a qualified electrician, and many charger suppliers arrange this as part of a package.
Does your car actually support bidirectional charging?
This is the most important question before spending anything. Bidirectional capability sits with the car manufacturer, not the charger manufacturer. Well-established examples include the Nissan Leaf's V2G and V2H capability via CHAdeMO, and various Kia, Hyundai, MG, and Volkswagen ID. family models offering V2L. Full V2H and V2G support on CCS is expanding, but which model years and trim levels qualify varies. Check your car's documentation, contact the manufacturer directly, and ask the charger supplier to confirm compatibility before purchase.
What about energy tariffs and V2G schemes?
V2G is most useful paired with a smart time-of-use tariff that allows you to import cheap electricity at off-peak times and export back when prices are higher. Schemes from suppliers such as Octopus Energy have been among the UK's more visible V2G products, but tariff availability, rates, and eligibility change frequently. The financial benefit depends heavily on your tariff structure, how much you drive, and your home's energy demand. Contact your energy supplier and check gov.uk for any available grants or incentives before committing.
Is a bidirectional charger worth it right now?
For most drivers, a bidirectional charger is still a considered purchase. The hardware costs considerably more than a standard wallbox, compatible vehicles are still a limited subset of the EV market, and financial return depends on tariff structures that are still maturing. That said, if you own a compatible car, generate solar power at home, or want energy independence, the economics can work. Technology is improving and prices are likely to fall as uptake grows. For everyday home charging, a well-chosen wallbox and a good EV charging cable remain the practical choice for most EV owners.
Frequently asked questions
Can any electric car use a V2H or V2G charger?
No. Bidirectional charging requires hardware support from the car manufacturer as well as a compatible charger. Well-known examples include the Nissan Leaf via CHAdeMO and various Kia, Hyundai, and VW ID. models. Support is expanding, but always verify with the manufacturer for your specific model and year before buying.
How much does a bidirectional home charger cost in the UK?
Bidirectional home chargers currently cost significantly more than a standard 7kW wallbox. The gap reflects the more complex inverter hardware required. Prices are changing as more products enter the market, so check current pricing directly with suppliers and factor in installation costs, which can be substantial depending on your home's electrical setup.
Do I need a special energy tariff to benefit from V2G?
Yes, in practice. V2G provides the best return when paired with a time-of-use tariff that lets you buy cheap off-peak electricity and export at a higher rate. Without that, you are simply cycling the battery without meaningful financial gain. Contact your energy supplier to find out which smart tariffs currently support bidirectional export.
Is there a government grant for bidirectional chargers?
Grant availability changes over time. The OZEV EV chargepoint grant covers standard home chargers, but eligibility for bidirectional units depends on current scheme rules. Check gov.uk for the latest guidance, as criteria and amounts are updated periodically and can change without much notice.
What is the difference between V2H and V2G?
V2H (vehicle-to-home) sends power from your EV battery directly to your home's circuits, bypassing the grid. V2G (vehicle-to-grid) exports power back to the National Grid via your energy supplier. V2H suits self-consumption and backup power; V2G is about grid services and tariff arbitrage. Some chargers support both; others are designed for one.
Will using bidirectional charging degrade my battery faster?
Most modern bidirectional systems include charge management software designed to minimise degradation by limiting depth of discharge and frequency of cycling. The evidence so far is broadly reassuring for well-managed systems, but it is still an evolving area. Check the manufacturer's warranty terms for any conditions relating to bidirectional use before committing.
Bidirectional home charging rewards careful research rather than impulse buying. Start by confirming your car's compatibility, then compare charger options and speak to your energy supplier about tariff support.

Which Electric Cars Support V2L (Vehicle-to-Load)?
V2L (vehicle-to-load) is available on a growing number of EVs in the UK, most commonly Hyundai, Kia, and BYD models. It lets you plug in tools, appliances and devices through the car's Type 2 inlet, drawing up to 3.6kW. You need a specific discharge cable — not a standard charging cable. Not every EV with a Type 2 inlet supports V2L: the car needs dedicated discharge hardware Most V2L cars deliver 3.6kW (16A), enough for a kettle, power tool, or portable heater You need a V2L discharge cable matched to your car's output socket type

How-to
Can I Use an Extension Lead to Charge My EV?
Do not use a domestic extension lead to charge an EV. The sustained current draw of EV charging pushes a standard extension lead beyond its safe operating limit, causing the lead and plug to overheat. Use a purpose-made EV charging cable from a dedicated outdoor socket or wallbox instead. EV charging draws 8–32A continuously for hours, far beyond what most extension leads tolerate safely Overheating causes fires at the plug, the lead, or both — even on reels that appear to handle the current The correct solution is a longer EV charging cable, not a longer extension lead

How-to
Charging Your EV When You Park on the Street
A 10m cable covers most kerbside situations. You also need a cable ramp cover to comply with local authority guidance on pavement obstruction, and you must use a dedicated wallbox or outdoor socket, not a standard plug through a window. 10m reaches a car parked directly outside; 15m if you need extra slack A cable ramp cover prevents trips and keeps the cable protected Check your local authority rules — some require a notification or permit
