The app also offers smooth switching with tailored step-by-step instructions on how to transfer plans and ensure that you're getting the best deal from your chosen retailer. Additionally, Joulius continually monitors the ever-changing electricity market on your behalf and alerts you if a better deal pops up.

The app lets you monitor your spending by flicking through your electricity usage history and seeing forecasts for the months ahead. You can also set alerts for bill payment deadlines. Joulius allows you to choose the criteria that are important to you by filtering results by certain retailers according to your preferences, solar-compatible plans or green power options, offers with deals, direct debit, dual fuel, and more.
