Martin Lewis talks a little about those that have already fixed. It's a low % due - probably due to varous restrictions on finding a fix when your company went bust or your previous fix ended.
"What happens to those who have fixed tariffs? Up to 15% of households are on fixed tariffs, many have locked in at higher prices, as they are risk averse and wanted to protect their bills. So what happens? Will they automatically be put on the price freeze?
If they are not automatically moved, will they be allowed to switch to the price freeze? If so and their tariff has early exit penalties (some of which can be £300+), will they still be charged? (Hopefully not, especially as it'd likely be an internal tariff change and exit penalties are often wiped for those).
This will need sorting out as a priority so those who've tried to protect themselves don't miss out. I would of course be lobbying for that and hope there's a chance some policymakers may just be reading this now to ensure it is addressed.
If you fixed within the last 14 days, do check when the cooling off period ends, as on Thursday when we hopefully know what's actually happening you may want to cancel.
PS: The political risk of policy shift has always been there (it's one I included in my Should I fix guide) though this is perhaps a more radical turn than many expected. The 'should I fix' call has never been easy. That's one reason when explaining the level it's worth considering at, I've always described as 'crystal ball gazing' with no way to know if it's the right call.
Some who have made the call to fix recently may feel frustrated by this. Yet ultimately remember, you made the call based on the information available at the time, that's all you can do, it was a good decision for you based on what you knew, even if the outcome doesn't turn out to be the best."
