Hi Sam
Whenever I apply for a MR I use a CRMR1 form but you do not have to use it.
How to ask for mandatory reconsideration
Contact the benefits office that gave you the decision. You can contact them: by phone
by letter
by filling in and returning a form
The contact details are on your decision letter.
www.gov.uk/mandatory-reconsideration There are details in our PIP Claim guide, half way down the page
