Bidirectional charging lets your car send power back to your home instead of just drawing it from the grid. After years of waiting, we’ve finally got affordable EVs that support it, chargers you can actually buy, and regulations that make installation straightforward. The question now isn’t whether it’s possible, but whether it makes financial sense for your household.
Which EVs Support Vehicle-to-Home in the UK?
You need a car with vehicle-to-home (V2H) capability, which is different from the vehicle-to-grid (V2G) tech that’s been around longer. V2H powers your house directly, while V2G feeds back into the national grid for payment. Some cars do both, some just one.
As of early 2026, your realistic options include the MG 5 EV (from around £28,000), the BYD Seal and Dolphin (both V2L and V2H capable), the Hyundai Ioniq 5 and Kia EV6 with the right spec, and the newer Genesis models. The Renault 5 that arrived late last year supports it too, which brought the entry price down considerably. Most Chinese brands launching now include bidirectional capability as standard, it’s become a tick-box feature rather than a premium add-on.
Tesla vehicles still don’t support V2H in the UK despite years of speculation, though there are mutterings about a hardware update. For now, if you’ve got a Tesla, this isn’t for you.
The Charger: Your Biggest Decision
You can’t use your existing AC wallbox for this. You need a bidirectional charger, and currently there are three main options available in the UK.
The Indra V2X charger (around £3,500 for the unit alone) works with most V2H-capable cars and has proven reliable in the installations I’ve seen. Wallbox’s Quasar 2 (approximately £4,200) is compact and well-regarded, though compatibility is pickier depending on your car’s charge port communication protocol. OVO’s Kaluza platform also offers V2H through their approved installers, bundling hardware and software together, typically coming in around £4,800 all-in.
These prices are just for the charger itself. Installation adds another £800 to £2,000 depending on your consumer unit (fuse box) setup, whether you need an earthing upgrade, and how far the charger sits from your existing electrics. If your home still has an old-style fuse box rather than circuit breakers, budget for the higher end of that range.
What About Solar and Home Batteries?
This is where it gets interesting, and potentially complicated. If you’ve already got solar panels and a home battery like a Tesla Powerwall or Givenergy system, adding V2H requires careful planning. Your car essentially becomes another battery in the system, but not all setups talk to each other nicely.
The ideal scenario is a smart energy management system that coordinates everything: solar generation, home battery, car battery, and grid import/export. Some V2H chargers include this intelligence, others need third-party energy management software. Octopus Energy’s Intelligent Octopus platform now supports some V2H setups, letting you optimise charging times and discharge periods automatically.
If you’re installing V2H alongside existing solar and batteries, expect to pay an integration specialist a few hundred pounds to configure everything properly. Getting it wrong means your expensive batteries fight each other about who charges first.
Real-World Costs and Savings
Let’s be honest about the numbers. A complete V2H setup costs between £4,500 and £7,000 including installation. That’s a serious chunk of money.
The savings come from using cheap overnight electricity (currently around 7p per kWh on Octopus Intelligent Go) to charge your car, then discharging it during peak hours when grid electricity costs 25p to 30p per kWh. If you’re replacing 10 kWh of peak-rate electricity with stored off-peak power every day, you’re saving roughly £2 daily, or around £700 annually.
At that rate, payback takes six to ten years, which is longer than most people keep a car. The financial case improves considerably if you’re also avoiding demand charges, using it as backup power during outages, or if peak/off-peak price gaps widen further. Some energy suppliers are trialling enhanced tariffs that pay you for exporting during specific peak periods, which could improve returns.
The real benefit, honestly, is backup power. When the grid goes down, your house keeps running. For most households, that peace of mind is worth more than the marginal electricity savings.
What You Actually Need: The Checklist
Here’s what to sort before committing: a compatible EV (check your exact model year and spec), a bidirectional charger matched to your car, adequate space on your consumer unit (typically 40A supply needed), off-street parking where you can install the charger, and ideally a time-of-use energy tariff that makes the economics work.
You’ll also want to think about battery degradation. Using your car battery for daily home backup adds charge cycles, though modern batteries handle this better than early EVs. Most manufacturers warrant batteries for eight years regardless, and the impact of moderate V2H use appears minimal based on the data we’ve seen so far.
My practical advice: if you’re buying a new EV anyway and have solar panels, V2H makes increasing sense in 2026. If you’re retrofitting everything just for V2H, the numbers are harder to justify unless you live somewhere with frequent power cuts or have a specific use case. The technology works, the costs are coming down, but it’s still a premium feature rather than a money-printing machine.
