2 I don't want to risk being trapped on a basic price cap tarrif if Tomato go under, nor would I wish that on the people who are buying our current home
3 The house we're moving to is currently supplied by Octopus (which hopefully will make the move straightforward), but doesn't have smartmeters; my experience with getting Octopus to provide them is good, whereas there are reports of people having difficulty getting them Installed with Tomato.
4 Octopus say they are aiming to do the switch in under a week, so I can be reasonably sure it will have happened and the billing sorted before we move
If we weren't moving, I would stay with Tomato until their situation becomes clearer. I've become accustomed to their low rates and made good use of both the nighttime and morning cheap periods. Let's hope they survive.
