Which Supplier Is Cheapest?

There is no single cheapest supplier for everyone.

Your cheapest option depends on:

• Your postcode

• Your gas and electricity usage

• Whether you have a smart meter

• Whether you have an electric vehicle

• Whether you want a fixed or variable tariff

• Whether you can shift usage to cheaper times

• Any exit fees with your current supplier

Always compare current tariffs before switching.

Which Supplier Is Best For EV Owners?

For EV owners, Octopus Energy is one of the strongest options because of tariffs such as Intelligent Go and Octopus Go.

These tariffs are designed around cheaper overnight charging and can reduce the cost of home EV charging when used properly.

If you charge a Tesla or another EV at home, Octopus Energy is worth comparing against standard fixed tariffs from other suppliers.

Which Supplier Has The Best App?

All major suppliers now offer apps or online account tools, but Octopus Energy is particularly useful if you want to monitor usage, track costs and manage smart tariffs.

British Gas, EDF, E.ON Next and OVO also provide digital account management, but the best app for you depends on what you need it to do.

If you only want to submit meter readings and view bills, most supplier apps can do that.

If you want detailed smart tariff and EV charging control, Octopus may be the better fit.

Which Supplier Is Best For Customer Service?

Customer service changes over time, so it is worth checking current reviews before switching.

In general, larger suppliers may have more established support teams, but that does not always mean better service.

Before choosing any supplier, check:

• Recent customer reviews

• Complaint handling

• App reviews

• Contact options

• Billing accuracy

• Support for smart meter issues
