You’ve probably seen it mentioned in EV spec sheets: Plug and Charge. It sounds brilliant in theory. You arrive at a charger, plug in, and the car handles payment automatically. No fumbling with apps in the rain, no tapping cards, no wondering if the charger recognizes your RFID fob. Just plug in and walk away.
The reality in the UK right now? It’s more complicated than the brochures suggest.
How Plug and Charge Actually Works
Plug and Charge uses a technical standard called ISO 15118, which is essentially a secure handshake between your car and the charger. When you plug in, the car and charger exchange encrypted certificates to verify your identity and payment details. Think of it like contactless payment, but the card is built into your car.
The key difference from app-based charging is that everything happens automatically through the charging cable itself. Your car communicates your account details, the charger authenticates them, and charging begins. In theory, it takes about 10 to 15 seconds from plug-in to electrons flowing.
The standard also enables clever features like the car telling the charger how much energy it needs, or even allowing bidirectional charging for vehicle-to-grid systems. But the headline benefit is simple: no phone, no card, no problem.
Which UK Networks Support It
This is where enthusiasm meets reality. Despite ISO 15118 being around since 2014, actual implementation in the UK has been glacial.
Tesla Superchargers have effectively had Plug and Charge for Tesla vehicles since forever, though they use a proprietary system rather than the ISO standard. If you’re driving a Tesla, you just plug in at any Supercharger and it works. No fuss, no apps. It’s genuinely brilliant, and it’s what every network should aspire to.
Ionity is the only major UK network offering proper ISO 15118 Plug and Charge right now, and even then, only certain vehicle models are supported. You’ll need to set it up through your car’s system first, which typically involves linking your Ionity account.
Beyond that? It’s mostly promises. Shell Recharge, bp pulse, and Gridserve have all announced plans to roll out Plug and Charge support, with most targeting 2025 or 2026. The challenge isn’t just upgrading charger hardware, it’s the entire backend system that handles authentication and billing.
Which Cars Actually Have It
Here’s where it gets properly frustrating. Many EVs technically support ISO 15118, but that doesn’t mean Plug and Charge works out of the box.
Porsche Taycan owners can use it on Ionity chargers, and it genuinely works well. The Audi e-tron GT and several newer Audi models support it. BMW’s iX and i4 have the capability, as does the Mercedes EQS and EQE range. The Hyundai Ioniq 5 and Ioniq 6 are equipped for it, along with the Kia EV6 and EV9.
But here’s the catch: supporting the standard and actually having it work are different things. Some manufacturers require a software update to activate it. Others need you to enable it through the car’s settings and link accounts. And even when everything’s set up correctly, reliability can be patchy.
Ford’s Mustang Mach-E and F-150 Lightning support it in the US but not yet in the UK. The Volkswagen ID range has the hardware but limited implementation. Tesla vehicles work perfectly on their own network but can’t use ISO 15118 on other networks.
Real-World Reliability Issues
I’ve spent more time than is probably healthy reading owner forums about Plug and Charge experiences, and the pattern is clear: when it works, it’s magic. When it doesn’t, you’re standing there wondering if you should just tap your card instead.
Common complaints include the handshake taking longer than expected, authentication failing for no obvious reason, and the system working perfectly one week then mysteriously not recognizing the car the next. Some users report needing to delete and re-add their vehicle certificate to fix intermittent issues.
Part of the problem is that it requires everything in the chain to work perfectly. Your car’s software needs to be up to date, the charger needs to support it, the network’s backend needs to recognize your certificate, and your payment details need to be current. One weak link and you’re back to the app.
Is It Worth Caring About?
Here’s my honest take: Plug and Charge is genuinely more convenient than apps or cards, but only when it actually works. The UK charging infrastructure isn’t quite there yet.
If you’re buying an EV today, I wouldn’t make Plug and Charge support a deciding factor. Contactless payment, which most major networks now offer, is reliable and takes about 10 seconds. The difference between tapping a card and having your car handle it automatically is marginal.
That said, if you’re choosing between two otherwise similar vehicles and one has ISO 15118 support, it’s a nice-to-have for future-proofing. As networks roll out support over the next couple of years, you’ll be ready.
The best practical tip? Set up accounts with Zapmap or Octopus Electroverse, which let you use multiple networks through a single app or card. You’ll get most of the convenience without waiting for Plug and Charge to become universal. And when Plug and Charge does work on your regular routes, you can use it. When it doesn’t, you’ve got a reliable backup that doesn’t involve standing in a service station car park trying to download yet another charging app.
