What types of tariffs are there? ⚡💡

Within the UK there are four major types of tariffs available to customers. These are:

Fixed 🔒

• The price per kWh stays the same throughout the day (though it can change over time). 
• Standard variable tariffs fall into this category. 
• This is the most common tariff for home energy users, but not ideal for EV charging because you can’t optimize for cheaper times.

Time of use ⏰

• Prices vary depending on the time of the day. 
• This tariff is very popular with EV users because they offer cheap overnight windows for charging. 
• Most have 2 rates per day, but some have 3 or 4. 
• Great for scheduling EV charging when energy is cheaper and greener.

Agile 🔄

• Prices change every 30 minutes, linked to wholesale energy costs. 
• Highly dynamic and influenced by weather conditions. 
• Prices are published the evening before, so only certain smart chargers can optimize for this tariff.

Smart EV tariffs 🔌

• The price depends on how you use the energy, not just when. 
• The tariff requires platform integration between your EV or EV Charger and the energy company. 
• The energy company controls when your car charges in exchange for very low rates.
