How to Maximise Savings with a Home EV Charger
Introduction
One of the biggest advantages of owning an electric vehicle is the ability to charge it at home. When used properly, home EV charging is typically the cheapest and most convenient way to keep your vehicle powered.
However, simply installing a charger is only the first step. To truly benefit financially, you need to understand how to use it effectively. Factors such as electricity tariffs, charging schedules, and charging habits can significantly influence how much you spend.
By making a few simple adjustments, many EV owners can noticeably reduce their running costs. In this guide, we’ll explain how to maximise savings with a home EV charger and ensure you get the most value from your installation.

Switch to a Dedicated EV Electricity Tariff
One of the easiest and most effective ways to reduce charging costs is switching to a dedicated EV electricity tariff.
These tariffs offer significantly lower electricity rates during off-peak hours, typically overnight when demand on the grid is lower. Some EV tariffs provide electricity for a fraction of the daytime price, meaning charging your vehicle at night can dramatically reduce your cost per mile.
For example, charging an EV overnight on a reduced tariff could cost several times less than charging during peak daytime hours.
Benefits of EV tariffs include:
- Lower overnight electricity rates
- Reduced cost per mile
- Predictable charging costs
- Better value compared to public charging
For drivers who charge regularly at home, the right tariff can make a substantial difference to monthly energy bills.
Schedule Your Charging for Off-Peak Hours
Switching to an EV tariff is only half the solution. To take full advantage of cheaper electricity, you must ensure your charging is scheduled correctly.
Many EV drivers move to an overnight tariff but forget to configure their charger. If your vehicle begins charging immediately when plugged in, it may draw power during peak hours when electricity is more expensive.
Modern smart chargers allow you to schedule charging times through a mobile app or built-in software. By setting your charger to operate only during off-peak hours, you ensure the vehicle charges when electricity is cheapest.
Once the schedule is set, the charger works automatically. You simply plug in the vehicle and let the system handle the rest.

Avoid Rapid Public Charging for Daily Use
Public rapid chargers are extremely useful, especially when travelling long distances or when you need a quick charge. However, convenience often comes with a higher price.
Rapid charging stations typically cost much more per kilowatt hour compared to home charging. In some cases, public rapid charging can cost several times more than electricity purchased through a home EV tariff.
While they are essential for long journeys, they should not be relied upon for everyday charging if you want to minimise costs.
Home charging offers several financial advantages:
- Significantly lower electricity prices
- No connection or service fees
- More predictable energy costs
- Greater convenience
Using rapid chargers only when necessary ensures you keep your overall EV running costs as low as possible.
Charge Efficiently for Everyday Driving
Another way to maximise savings is by charging only what you need.
Many drivers plug in every night and charge the battery to 100%. While this may seem like the safest option, it often results in unnecessary energy usage.
For most daily driving, charging your vehicle to around 80–90% is usually more than sufficient. This approach offers several benefits:
- Reduced electricity consumption
- Less strain on the battery
- Improved long-term battery health
- More efficient energy usage
Planning your charging around your weekly mileage allows you to use energy more efficiently while still maintaining enough range for daily travel.
Combine EV Charging with Solar Energy
If you want to maximise savings even further, combining solar panels with EV charging can be an excellent solution.
Solar panels generate renewable electricity during daylight hours, which can be used to charge your vehicle. Instead of drawing power from the grid, you can power your EV using energy generated directly from your roof.
This approach offers several benefits:
- Reduced electricity bills
- Lower carbon footprint
- Greater energy independence
- Long-term cost savings
Many homeowners choose to combine EV charging with solar systems and battery storage to store excess energy generated during the day. Together, these technologies can create a highly efficient home energy ecosystem.
Use Smart Charger Features
Modern EV chargers include several smart features designed to optimise charging and reduce costs.
Many chargers allow users to monitor electricity usage, schedule charging times, and integrate with smart home systems. Some models can even respond automatically to electricity price changes, ensuring charging occurs when energy is cheapest.
Common smart charger features include:
- Scheduled charging
- Energy monitoring
- Remote control via mobile apps
- Integration with solar systems
- Load balancing with other household appliances
Taking advantage of these features can significantly improve charging efficiency and help you better manage energy costs.
Professional installers can also help configure these systems during installation to ensure they are optimised from day one.
Ensure Your Charger Is Professionally Installed
A properly installed charger ensures safe, efficient, and reliable operation. Professional installers assess your electrical system, recommend the right charger model, and configure smart features to maximise performance.
They can also advise on:
- The best charger location
- Electrical capacity and upgrades
- Smart charging setup
- Integration with renewable energy systems
If you are considering installing a charger or upgrading your current system, professional guidance can help ensure you get the best long-term value.
Final Thoughts
Home EV charging should make running your electric vehicle simpler, cheaper, and more convenient. However, achieving the lowest possible costs requires the right setup and charging habits. By choosing an EV electricity tariff, scheduling charging during off-peak hours, limiting rapid public charging, and using smart charger features, you can significantly reduce your energy costs.
Combining EV charging with renewable technologies such as solar panels and battery storage can further enhance savings and sustainability. If you’re unsure whether your current charging setup is operating as efficiently as possible, it may be worth speaking to a professional installer for advice.

Frequently Asked Questions
Yes, charging an EV at home is usually much cheaper than using public rapid chargers. Home electricity tariffs, particularly EV tariffs with off-peak rates, significantly reduce the cost per kilowatt hour. Over time, charging at home can save EV drivers a substantial amount compared to relying on public charging networks.
The best time to charge an electric vehicle is typically overnight when electricity demand is lower. Many energy providers offer off-peak EV tariffs with reduced electricity rates during these hours. Scheduling your charger to operate overnight allows you to take advantage of these lower prices and reduce overall charging costs.
A smart charger is highly recommended for home EV charging. Smart chargers allow you to schedule charging times, monitor energy usage, and optimise charging based on electricity tariffs. These features help maximise savings, improve efficiency, and ensure your vehicle charges when electricity is cheapest.
Yes, solar panels can significantly reduce EV charging costs by generating renewable electricity at home. This energy can be used to charge your vehicle instead of drawing power from the grid. When combined with battery storage, solar systems can provide even greater energy independence and long-term savings.
Charging to 100% every day is not always necessary for most drivers. Charging to around 80–90% is typically enough for daily journeys and can help maintain long-term battery health. Adjusting charging levels based on your driving needs helps reduce unnecessary energy use and keeps charging more efficient.
Savings vary depending on electricity tariffs and driving habits, but home charging is generally far cheaper than petrol, diesel, or public charging. Many EV drivers find that overnight tariffs significantly reduce their cost per mile, making electric vehicles one of the most economical options for everyday transport.
