To change over to Economy 7, you'd need to get a smart meter installed by us.
Once you have one installed, we can remotely change it to Economy 7, you'll just need to send us an email to email@example.com, or send us a message to our Facebook or Twitter pages.
It's worth checking the unit rates to make sure it's worth switching over to, however, we recommend that you use at least 30% of your electricity in the night time for the change to be cost effective.
