Quicker switching

Flip when time is right

Better switching, greater savings

Here’s what separates our new algorithm from the others.

Fairer

Joules ensures that whenever you're switched, you'll pay less for energy than you currently do. The traditional method of calculating savings isn't always fair for UK energy customers, and can result in heavily inflated “phantom” savings.

Smarter

As we search for better tariffs throughout the year, Joules considers more than just individual savings. Amongst other things, we have to make sure exit fees are properly accounted for. Since Joules is likely to find you better deals while you're within contract, it will factor exit fees on new deals as well as old ones into each flip for you.

Quicker

Joules takes ‘switching times’ into account, prioritising tariffs that you’ll benefit from sooner. The faster you can switch to a cheaper tariff, the less time you spend on your more expensive current deal — and the more you save.
