If you have a terminal illness (that is if you are suffering from a progressive disease where death can be expected within 6 months) you will automatically receive the daily living component enhanced rate. You will also be able to apply for the mobility component and receive it immediately if you qualify.
If you are in a care home you will be entitled to the mobility component so long as you satisfy the qualifying conditions.
If you are paid PIP you are free to spend the money in the way that suits you best.
