Plug and Charge is one of those features that sounds almost too good to be true: you arrive at a compatible charger, plug in your car, and charging starts automatically. No app to open, no RFID card to tap, no payment screen to navigate in the rain. The car and charger simply recognise each other, authenticate, and get on with it.
The technology works, and when it does, it genuinely feels like a glimpse of how EV charging should always work. But here’s the reality: in the UK right now, Plug and Charge is patchy at best. Whether it’s worth factoring into your next EV purchase depends entirely on which networks you’re likely to use.
How Plug and Charge Actually Works
The technical name is ISO 15118, a communication standard that allows your car and the charger to exchange information through the charging cable itself. Think of it like contactless payment for your car: the charger recognises your vehicle’s unique identity, checks it’s authorised to charge, and bills the correct account automatically.
For this to work, you need three things: a car that supports ISO 15118, a charging network that’s implemented it properly, and the car registered with that network’s system. Miss any one of those, and you’re back to opening an app.
Which Cars Support Plug and Charge?
The list is growing, but it’s still relatively short. In the UK market, these vehicles currently support Plug and Charge (at the time of writing):
Tesla Model 3 and Model Y (at Tesla Superchargers only), Porsche Taycan, Audi e-tron GT, BMW iX and i4 (certain variants), Mercedes EQS and EQE, Ford Mustang Mach-E and F-150 Lightning (where available), Genesis GV60, Hyundai Ioniq 5 and Ioniq 6, and Kia EV6 and EV9.
That list comes with caveats. Some manufacturers have rolled out support via software updates, so earlier models might have gained the feature retrospectively. Others have it enabled in principle but haven’t activated it with many UK networks yet. It’s frustratingly unclear, and dealers often don’t know the answer.
Which UK Networks Support It?
This is where things get properly complicated. IONITY was the early champion in the UK and generally works well with compatible cars, though you’ll need to register your vehicle through their app first. Tesla Superchargers offer seamless Plug and Charge for Tesla vehicles, obviously, and now support it for some non-Tesla EVs too, though the experience varies wildly by car manufacturer.
Gridserve has implemented ISO 15118 at many of its Electric Highway locations and some Electric Forecourts, with decent reliability in my experience. bp pulse claims support at newer rapid chargers, though I’ve found it inconsistent. Shell Recharge is gradually rolling it out. Osprey has it at select locations, and Pod Point supports it on some newer units.
Here’s the honest truth: even when your car and the network theoretically support Plug and Charge, it doesn’t always work. I’ve tested a Hyundai Ioniq 5 at various IONITY chargers and had it work flawlessly three times, then fail completely on the fourth visit for no obvious reason. At that point, you’re reaching for your phone anyway.
The App Fallback Problem
This is why Plug and Charge isn’t quite the purchasing priority it might seem. Every network that supports it also has an app, and you’ll need that app installed anyway for the times when Plug and Charge doesn’t work. You’re not escaping apps entirely, you’re just reducing how often you need to use them.
That’s still worthwhile, particularly at motorway services when you’re tired or it’s pouring with rain. But it’s not transformative in the way that, say, a genuinely rapid charging curve is.
Should This Influence Your Buying Decision?
If you’re choosing between two otherwise identical cars and one has Plug and Charge, sure, it’s a nice tiebreaker. But I wouldn’t prioritise it over range, charging speed, price, or whether you actually like sitting in the thing.
The infrastructure simply isn’t widespread enough yet. If you do most of your charging at home and only use public rapid chargers occasionally, you’re not saving much hassle. And if you use apps like Zapmap or Octopus Electroverse that provide access to multiple networks through one interface, you’re already getting much of the convenience without needing ISO 15118.
Where Plug and Charge genuinely shines is for company car drivers or fleet users who charge at the same network repeatedly. If your regular motorway route has IONITY chargers and you’re considering an Ioniq 5, the feature becomes more valuable because you’ll use it consistently.
What’s Coming Next?
The situation should improve. More networks are adding support, more cars ship with it as standard, and the technology itself is maturing. In a couple of years, Plug and Charge will probably be unremarkable rather than noteworthy.
Until then, I’d suggest checking which networks you actually use most often (Zapmap’s statistics feature is helpful here) and whether your shortlisted cars support Plug and Charge with those specific networks. Register your vehicle with any networks that require it, but don’t be surprised when you still need the apps half the time. At best, Plug and Charge is a lovely convenience when it works. At worst, it’s a feature you’ll forget your car even has.
