Hi mb,
No, you don't need to speak to the assessor before asking for a Mandatory Reconsideration, nor would you actually be allowed to do so.
have a look at our advice regarding MR and also use our PIP guide to decide whether you think you should have been scored more highly on the descriptors that you did score for or whether you think you should have been awarded points for other descriptors too ( or a mixture of both).
PIP help for claimants Mandatory reconsideration FAQs Make sure that you get the request for MR submitted in good time.
If/when you have further questions, please reply to the message and we will do our best to help.
