Hi, I'm in SA and we just got an email with the changes to our tariffs from July 1. Is it correct that there is a shoulder period from 10AM-3PM where the controlled load tariff is cheaper? We have underfloor heating that is currently running on controlled load in the evening. How do I take advantage of this cheaper shoulder rate as there is currently no power being delivered to the underfloor heating during the shoulder period. Does something need to change on our smart meter, or is it to do with our underfloor heating? Thank you.
