Hi Maxine,
I'm sorry to hear that your Mum's PIP claim has been refused
At this stage you can request a Mandatory Reconsideration and/or make a new claim. Obviously, if you were to make a new claim you would have to feel that there was something you can do to improve your chances next time.
You can submit a request for MR by phone if you wish but we do recommend that you follow this up in writing. You can then progress to a formal appeal if the MR does not go in your favour.
This is all covered in our PIP guides.
