Plug and Charge sounds like science fiction: you arrive at a compatible charger, plug in your EV, and it automatically authenticates your account and starts charging. No app to open, no RFID card to tap, no contactless payment. The car and charger simply talk to each other using a protocol called ISO 15118, which lets them exchange authentication details securely through the charging cable itself.
It’s genuinely convenient when it works. I’ve tested it across several UK networks with a Porsche Taycan, and that moment when you plug in and the charger just starts without any faff is oddly satisfying. But here’s the reality: adoption in the UK remains patchy, the technology still has reliability issues, and you absolutely shouldn’t choose an EV based solely on whether it supports Plug and Charge.
Which Cars Support Plug and Charge?
The list is growing but still selective. At the time of writing, you’ll find ISO 15118 support in most Porsche Taycans and Macan Electrics, the BMW i4 and iX (depending on specification), Mercedes EQS and EQE models, Polestar 3, and Ford’s newer EVs including the Explorer and Capri. The Hyundai Ioniq 5 and Kia EV6 have the hardware but it’s not always activated by default, you might need a dealer to enable it.
Tesla uses its own version at Tesla Superchargers, which works flawlessly if you’ve added your car to your account, but doesn’t work with the ISO 15118 standard that other networks use. Volkswagen ID models are hit and miss, some support it after software updates, others don’t. If you’re buying an EV specifically for this feature, check with the dealer and get it in writing, because manufacturer websites aren’t always current.
UK Networks That Support Plug and Charge
This is where things get interesting. Ionity is probably the most reliable, nearly all of their UK sites support Plug and Charge and it typically works first time. Gridserve has been rolling it out across their Electric Forecourts and the experience has been solid in my testing, though not every charger at every site is enabled yet.
bp pulse claims support at selected high-power chargers, but I’ve had mixed results. Sometimes it works perfectly, other times the charger simply doesn’t recognise the car and you’re back to using the app. Osprey says they’re implementing it but availability is extremely site-dependent, I’d still carry the app as backup.
Pod Point, InstaVolt, and most destination chargers don’t support it at all. You’re using an app, RFID card, or contactless payment at those networks regardless of what your car can do.
How It Compares to App-Based Charging
I spent a month deliberately using Plug and Charge wherever possible, then a month using apps and contactless for comparison. The honest assessment? When Plug and Charge works, it saves perhaps 20 seconds compared to opening an app. That’s genuinely nice, especially in the rain, but it’s not life-changing.
The trade-off is that you have less visibility into what’s happening. With an app, you can see the price before you start, check the charging speed in real time, and stop the session easily. With Plug and Charge, you plug in and hope everything’s configured correctly on the backend. I’ve had sessions start at the wrong tariff because my account settings weren’t quite right, and you only discover this when you check your invoice later.
App reliability has also improved massively in the last year. Zapmap’s payment feature works across multiple networks, Octopus Electroverse is remarkably stable, and even individual network apps crash less than they used to. The gap between app-based charging and Plug and Charge has narrowed considerably.
Common Problems and Failure Points
The technology still fails more often than it should. Sometimes the charger doesn’t recognise your car, even though both theoretically support ISO 15118. Sometimes your car isn’t properly registered in the network’s backend system, which requires a phone call to customer service to sort out. I’ve had chargers that worked perfectly with Plug and Charge one week, then required the app the next week after a software update.
There’s also the certificate renewal issue. The digital certificates that enable secure authentication expire periodically, and if your car’s certificate expires and doesn’t renew automatically (which has happened with some BMW models), Plug and Charge stops working until you get a software update from the dealer.
Is It Worth Prioritising?
If you’re choosing between two EVs you otherwise like equally and one has Plug and Charge, sure, it’s a nice tiebreaker. But it absolutely shouldn’t be a primary decision factor. The charging experience depends far more on network reliability, charger availability, and pricing than on whether you spend 20 seconds opening an app.
For most UK drivers, you’ll still need charging apps anyway because the majority of public chargers don’t support Plug and Charge. You’re not simplifying your life dramatically by having it, you’re just adding one more option for a subset of your charging sessions.
What might change this assessment is if UK adoption accelerates significantly. If we reach a point where 80% of rapid chargers support it reliably, then yes, it becomes genuinely useful. We’re not there yet, and I wouldn’t bet on getting there in 2026 either. For now, think of Plug and Charge as a nice bonus rather than an essential feature, and keep Zapmap or your preferred charging app installed regardless.
