'Go' is only available if you have an EV, so thats not an option.
'Flux', 'Snug' & 'Cosy' all seem to have various restrictions on who can have them as well.
Economy 7 is still an option, and in winter could be a consideration, as I have partial electric heating.

I also keep an eye on the fixed price as they often review it, the current 23p is a little high.
I moved to fixed Gas at 5.67p in early November, which has saved me a lot in the last 2 months.

This is my first year on Agile, so its obviously a bit of learning, I expected winter to have bad days.
Those bad days are irritating of course, but they generally get cancelled out by the good (cheap days).
The tarriff comparisons (using my actual consumption) show that overall Agile is still the cheapest for me (since I got the meter, so Aug - Dec 2023).

Even in January (so far) the bad days have not yet cancelled out the good days.
I expect they will when todays figures are in, but there is still the rest of the month.

I keep my eye on it, but there seems no reason to make panic decisions atm.
