Hi Lindsay
You can put in a late appeal. Your appeal will be considered late if it is received more than a calendar month after the date on the notice.
If it is late you must give reasons why it is late. If you do not give reasons for lateness your appeal may not be considered. So in your case you would write that you needed assistance to put in an appeal and you were unable to get an appointment with the CAB.
Many late appeals are accepted so don’t give up if you are outside the one month time limit.
If your appeal is late and you have given reasons for lateness the Tribunals Service will treat it as
having been received in time, unless the DWP object within 4 weeks. If they do object you will
have a chance to comment and a Tribunal Judge will then decide whether to accept it.
All information is available in our PIP Appeals guide
