How Much Does It Cost To Charge A Tesla With Octopus Energy? (2026)

One of the most common questions asked by electric vehicle owners is:

How much does it actually cost to charge a Tesla at home?

The answer depends on your electricity tariff, charging habits, battery size and how many miles you drive each month.

As a Tesla owner using Octopus Energy, I've found that home charging is significantly cheaper than relying on public rapid chargers.

In this guide, I'll explain the factors that affect charging costs and how Octopus Energy tariffs can help reduce them.

Is Charging A Tesla At Home Cheaper?

In most cases, yes.

Home charging is usually much cheaper than using public rapid charging networks.

The exact saving depends on:

• Your electricity tariff

• The size of your Tesla battery

• Your driving mileage

• Whether you charge during off peak periods

• Whether you use a smart charging tariff

For many Tesla owners, charging overnight can significantly reduce running costs.

How Much Electricity Does A Tesla Use?

Tesla models vary in battery size and efficiency.

The amount of electricity used depends on:

• Model type

• Driving style

• Weather conditions

• Speed

• Battery size

Motorway driving generally uses more energy than local journeys.

Cold weather can also increase electricity consumption.

What Affects Tesla Charging Costs?

Several factors can increase or decrease your charging costs.

For many households, home charging is where the biggest savings are achieved.
