Daily living component
Standard rate – If you have a limited ability to carry out daily living activities - £57.30 (2017 to 2018 - £55.65)
Enhanced rate – If you have a severely limited ability to carry out daily living activities - £85.60 (2017 to 2018 - £83.10)
Standard rate – If you have a limited mobility - £22.65 (2017 to 2018 - £22.00)
Enhanced rate - If you have a severely limited mobility - £59.75 (2017 to 2018 - £58.00)
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.
