Seeking the Best EV Tariff: Struggling with High Costs? TESLA Model S (5YJS) (09.2012 - ...)

To manage the high costs of charging your 2016 Tesla Model S in the UK, finding the best EV electricity tariff and optimizing your charging times are key strategies.

Tips for Finding the Best EV Tariff
- Look for dedicated EV tariffs: Specialized EV tariffs can reduce your charging costs by up to 70% compared to standard rates. For example, while a full charge on a standard tariff might cost around £24.86 for a 100 kWh Tesla Model S battery, an EV tariff charging at about 7p/kWh could lower this to roughly £7.50 per full charge.
- Compare suppliers: Use comparison websites that include EV tariffs, as many energy providers now offer plans tailored for EV owners with cheaper off-peak rates.
- Check for smart meter compatibility: Many EV tariffs require a smart meter to enable time-of-use pricing and accurately measure off-peak charging.

Managing Peak vs. Off-Peak Rates
- Charge overnight during off-peak hours: Most EV tariffs offer significantly cheaper electricity overnight (often from around 11 pm to 7 am). Scheduling your Tesla to charge during these hours can drastically cut costs.
- Use Tesla’s built-in charging scheduler: Set your Model S to start charging only during off-peak periods to avoid expensive peak rates.
- Avoid daytime or peak-time charging at home: Electricity prices during the day can be 3-4 times higher than off-peak rates, so delaying charging until off-peak hours is financially beneficial.
- Public charging caution: Public rapid chargers, especially ultra-rapid networks like Ionity, can cost as much as £0.74 per kWh or more, making a full charge over £70. Use public chargers sparingly and only when necessary.

Additional Cost-Saving Tips
- Install a Tesla Wall Connector: Although it has an upfront cost (£300-£475), a dedicated home charger can improve charging efficiency and reduce energy waste.
- Monitor your charging efficiency: Tesla’s charging efficiency is around 85%, so expect some energy loss; optimizing charging habits helps reduce wasted electricity.
- Consider solar panels or home battery storage: If you have solar, charging your Tesla during sunny periods can further reduce grid electricity use.

* Switch to a dedicated EV tariff with low off-peak rates (around 7p/kWh) to cut your charging cost by up to 70%.
* Charge overnight during off-peak hours using Tesla’s charging scheduler.
* Avoid expensive public rapid chargers unless necessary.
* Consider installing a Tesla Wall Connector for better home charging efficiency.

By combining these strategies, you can significantly reduce your Tesla Model S charging expenses while maintaining convenience.
