Why EV Charging Is More Reliable — but More Expensive
Public EV charging in the UK has just taken a major step forward.
Thanks to new reliability rules introduced in 2026, rapid charging networks must now meet a “99% uptime” requirement. This means chargers must be working almost all the time, dramatically reducing the frustration drivers used to face when arriving at broken or offline chargers.
For EV drivers, that’s great news.
But there’s a catch: keeping chargers running 24/7 isn’t cheap, and the cost of that reliability is increasingly being passed on to drivers through higher charging prices and new penalty fees.
For many EV owners, this has made public rapid charging the most expensive way to power their vehicle.
The Good News: Broken Chargers Should Be a Thing of the Past
The new reliability rules affect the UK’s major public charging networks, including companies like BP Pulse, Instavolt, and IONITY.
Under the new standards, charge point operators must ensure rapid chargers remain operational almost all the time. This requires:
- Continuous remote monitoring
- Faster repair response times
- On-site technician availability
- Hardware upgrades and network maintenance
These improvements are designed to make EV travel easier and eliminate one of the biggest frustrations drivers previously experienced.
However, maintaining this level of service comes with significant operational costs.
The Cost of Reliability: Rapid Charging Prices Are Rising

To cover the cost of maintaining near-perfect reliability, many networks have raised prices for public rapid charging.
In 2026, the average UK rapid charging price now sits between 75p – 89p per kWh.
By contrast, many home energy tariffs allow EV charging overnight for around 7p – 9p per kWh. That means public rapid charging can be almost 10 times more expensive than charging at home during off-peak hours.
💡 Tip: If you want to avoid these high costs entirely, consider a Portable EV Charger that lets you charge safely anywhere you have access to a standard outlet.
The Hidden Sting: EV Idling Fees
Higher electricity prices are only part of the story.
To maintain the new 99% uptime targets and keep chargers available for other drivers, many charging networks have introduced or increased idling fees. These fees apply when a car remains connected to a charger after charging is complete.
Typical idling fees now range from £0.50 to £1.00 per minute.
A 20-minute delay at a motorway café could easily cost more than the electricity itself.
How Idling Fees Catch Drivers Out
Imagine stopping at a motorway service station to charge your EV. You plug into a rapid charger, grab a coffee, and take a short break. While you’re away, your car reaches 80–100% charge.
If you take a little too long getting back to your vehicle, the charger may begin applying idling fees.
💡 Smart Alternative: A Third Rock Energy Portable EV Charger lets you bypass these idling fees completely by charging at your destination overnight, whether at a hotel, Airbnb, or family home.
The Smarter Strategy: Destination Charging

One way to avoid both rapid charging premiums and idling fees is to charge your EV at your destination instead of relying on motorway chargers.
This is known as destination charging.
Instead of paying high public charging rates, you simply plug your car in overnight at locations such as:
- Hotels
- Airbnbs
- Holiday rentals
- Family homes
- Standard household sockets
Charging overnight at lower power levels is often cheaper, more relaxed, and avoids the pressure of waiting beside a rapid charger.
Why Destination Charging Is Growing Fast
Many EV owners are discovering that destination charging offers several advantages:
Lower Costs
Charging overnight using a standard socket or low-power outlet typically costs far less than motorway rapid charging.
No Idling Fees
Because you’re charging at your destination, there’s no pressure to move your vehicle as soon as charging finishes.
Less Stress
You can simply plug in when you arrive and wake up to a charged car.
💡 Product Recommendation: The Third Rock Energy Type 2 13A Portable EV Charger 10m provides adjustable amperage settings, making it perfect for destination charging.
How Portable Chargers Make Destination Charging Possible

Destination charging works best when drivers have access to a portable EV charger.
Chargers from Third Rock Energy are designed to allow EV owners to plug into standard outlets safely, giving drivers greater flexibility and independence when travelling.
Why Many EV Drivers Carry a Portable Charger
Portable EV chargers are becoming increasingly popular for drivers who want more charging options on the road.
Key benefits include:
- Charging at hotels or holiday accommodation
- Using standard sockets when no charger is available
- Avoiding expensive rapid charging networks
- Reducing the risk of idling fees
- Greater travel flexibility

The Cheapest Way to Charge an EV in the UK

For most drivers, the most affordable charging strategy combines three approaches:
- Home charging on off-peak tariffs
- Solar charging where available
- Destination charging during travel
Public rapid chargers are still essential for long motorway journeys, but relying on them for everyday charging can become expensive, look here to compare EV chargers, and find the best home setup.
Charging Independence in the EV Era

The new UK public charging laws in 2026 have made public chargers more reliable than ever.
But the cost of maintaining that reliability means drivers face higher prices and stricter idling penalties.
For many EV owners, the smartest approach is to treat rapid chargers as occasional tools rather than everyday solutions.
With a portable charger from Third Rock Energy, drivers can charge safely at destinations, avoid premium motorway rates, and travel with far greater confidence.
Summary
The UK public charging laws in 2026 require rapid EV chargers to meet a 99% uptime reliability standard, making public charging networks far more dependable.
However, maintaining this reliability has increased costs, with rapid charging prices now averaging 75p–89p per kWh, and many networks have introduced EV idling fees of £0.50–£1.00 per minute.
To avoid these costs, many EV owners are turning to destination charging, using Third Rock Energy portable chargers to charge overnight at hotels, holiday rentals, or family homes, providing a cheaper and more flexible alternative to public rapid chargers.
