I found the per unit caps set by ofgem in April 2021.

19p for electric and 3p for gas, added 12% for October 2021, this suggests to me the variable deals cant go up much in price because of the cap. So I went with variable on Octopus, their fixed is circa 25% higher for me way above the cap, and for a heavy gas user would be nearer 50%.
