Hi Glissandro
PIP reviews forms can be sent out up to a year before the PIP award's end date. If your PIP is due to end in October 2027, you could be reviewed any time from November 2026.
I know it's scary, but as it stands at the moment, you will likely be sent a review form to complete and will be assessed. It doesn't mean you will automatically lose your PIP. When the time comes, you will be able to read through the guide on how to complete your form.
It is possible that if they delay issuing a review form, you may be fortunate enough to be close enough to State Pension Age, that they decide to move you onto an ongoing PIP award, in which case your PIP would continue. However, I cannot confirm that this will happen at the moment.
