Unless you have solar and/or batteries (or work regular night shifts) then the tracker really is a no brainer at this time of year (perhaps all year). As a dynamically changing flat rate for each day it consistently performs better than the Agile or similar tariffs.
Right now I don't see a reason to change. Might reconsider that coming up to winter depending on the noise around word wide gas supplies and the issues with Russia at which point getting a fixed might be the way to go.
It's crazy that when I changed to Tracker at the start of the year the representative on the phone was talking about the benefits of Agile pricing every 30 mins but I pointed out that on average the tracker was always cheaper which they didn't understand.
