• Whole-home energy savings: Reduced off-peak rates apply to your entire household, allowing you to run heavy appliances for less overnight.

• Dynamic daytime charging: Plugging in whenever you're home triggers bonus low-cost charging windows during sudden drops in energy demand.

• Cost transparency: Live status tracking, detailed history, and cost estimates remove the guesswork from your energy bill.

• Flexible override: The app’s "Boost" feature lets you instantly bypass schedules to charge immediately at standard rates when needed.

• Up to £435 annual savings: Integrating compatible EV charging tech unlocks extra daytime savings worth up to £435/year over standard tariffs1.

Switching to an electric vehicle (EV) is one of the most rewarding steps you can take toward reducing your tailpipe emissions and adopting a lower-carbon lifestyle2. Plugging your car in at night feels simple enough, but are you getting the most out of your EV charging?

If you’re just plugging into the wall and letting your car draw power straight away, you might be missing out on lower overnight energy rates. To help maximise the potential financial and practical benefits of electric driving, moving beyond standard charging into intelligent energy management can make a significant difference.

That is where a dedicated electric car charging app comes in. Paired with a smart EV tariff like Next Drive Smart, the E.ON Next Home app turns charging your EV from a basic power point into a smart charging system designed to automatically schedule your charging during off-peak hours while you sleep.

What is smart charging and how does it work?

Smart charging is the clever technology that connects your electric vehicle, your home charger, the energy grid, and your energy supplier. Instead of drawing electricity at peak rates the moment you plug in, smart charging automatically adjusts when and how fast your vehicle powers up. It shifts your electricity demand to the cheapest times available.

The E.ON Next Home app automatically manages your power needs around cheap off-peak rates. You don't need to stay up until midnight to start a charge or spend time figuring out complicated timers. You simply plug your EV in, set your departure time and target battery level in the app, and we'll take care of the rest. The app automatically schedules your charging during low-cost off-peak hours3. The longer you leave your car plugged in overnight, the more low-cost hours our system has to pick from, keeping your running costs low while balancing demand on the UK energy grid. A smart EV tariff doesn't just work night shifts, it spots cheaper energy windows during the day, too. By keeping your car plugged in whenever you're at home, the E.ON Next Home app can automatically trigger smart charging whenever a surprise low-cost window opens up. Best of all? That bargain rate applies to your entire household's electricity, not just your car.

Budgeting and transparency: Turning energy use into clear data.

For many electric car owners, home charging costs can feel like a bit of a mystery until the monthly bill arrives. Without visual tracking, estimating what each charge costs requires manual maths.

Connecting your car to the E.ON Next Home app gives you immediate visibility over every charge session, with clear cost estimates and detailed billing reports. You can view your full charging history, check live status, and monitor future charging plans at a glance.

The app displays your off-peak rates alongside your actual usage, making it easy to calculate how much money you save. Having this real-time data helps you budget with complete confidence.

Total flexibility: Staying in control of unplanned journeys.

Handing control of your charging schedule over to an automated system and your energy supplier might feel daunting, especially if your routine changes daily. What happens if an emergency pops up or you need to make an unexpected trip?

Smart charging doesn't mean losing control of your car. The E.ON Next Home app balances automated energy management with an instant manual override, giving you full flexibility whenever plans change.

Scheduled readiness tailored to your routine.

Set your departure time, for example for 7am, and the app organises your low-cost charging windows to ensure your car's fully topped up and ready to go exactly when you leave the house.

Instant override with the Boost feature.

With remote start and stop options alongside real-time status notifications, you're not stranded when unexpected moments pop up. If an emergency arises, you can instantly by-pass your scheduled off-peak plan using the built-in Boost feature. Tapping ‘Boost’, commands your charger to draw power immediately at standard rates, giving you total peace of mind whenever plans change and you need an instant charge.

Whole-home savings: Lowering bills beyond your charging.

The perks of smart charging extend far beyond your driveway. When you set up smart charging on the Next Drive Smart tariff, you get a low 8p per kWh off-peak rate every night from midnight to 6am. What makes this even better is that this low rate applies to your entire household's electricity use during that six-hour window, not just your car.

The app serves as the anchor for broader household efficiency by integrating with household energy use. Because your low unit rate applies across the home overnight, you can set energy-heavy appliances like washing machines, tumble dryers, and dishwashers to run while you sleep.

Extra daytime savings with myenergi zappi chargers.

We've made whole-home energy savings even better through our partnership with myenergi. If you have a compatible zappi charger (such as the zappi 2.1 or zappi GLO), the E.ON Next Home app can now schedule these bonus smart charging windows during the day when grid capacity is available.

When these daytime smart charges occur, that same cheap 8p per kWh rate applies to your entire house. For a typical driver covering 8,000 miles a year, switching to Next Drive Smart could deliver savings of up to £4351 compared to charging on a standard variable tariff.

How to connect to the E.ON Next Home app and start saving.

Getting started with smart charging is simple. Follow these basic steps to get connected:
