Energy tariffs

If your tariff is coming to an end this month, now is the time to switch to a top energy deal

If your energy deal is coming to an end in March, now is the time to switch before you pay more for a standard tariff. 

When your tariff comes to an end, your supplier will switch you to its standard (also known as variable) tariff. In most cases, this will be more expensive. In some cases, it will be much more expensive. 

Read on to see if your energy deal is coming to an end, and see how much more you'll pay if you don't switch. Scroll down to reveal the five cheapest energy deals.

Switch your energy deal now and avoid exit fees

Your supplier has an obligation to alert you between 42 and 49 days before your tariff ends. You don't have to wait until the tariff has actually ended to switch, as suppliers are not allowed to charge you an exit fee during this time. 

It's best to switch as soon as you receive the notification, as you could waste money by ending up on the standard tariff while you wait for the switch to go through.

So if your tariff is ending at the end of March, you should be able to switch now to avoid any exit fees.
