UC claim -health conditions UC50 form

Can you inform me of the procedure of claiming UC with old and a new health condition? Old health conditions are listed in current Claimant Commitment (I'm on income based JSA) but a new condition that I was hoping would improve wasn't added when it began. Should I add this to my Claimant Commitment before I apply for UC?

Is the UC claim form and UC50 form completed and sent together?

Will a 'FIT NOTE' be required with the UC50 form?

Will I be required to provide medical evidence with the UC50 form?

Thank you Gordon.

I am not clear on the process:
'make a claim for UC and once this is accepted you declare yourself unfit for work and ask to be assessed'

When I make the UC claim, how is this accepted?
How do I declare myself unfit, (how does the Fit Note come into play) and ask to be assessed?
I am particularly worried if at the time I need a Fit Note the GP familiar with my case will be away?

Thank you Gordon.

In regard Activity 9: Evacuation of the bowel and/or bladder (LCW)
That is: Absence or loss of control whilst conscious leading to extensive evacuation of the bowel and/or bladder, other than enuresis (bed-wetting), despite the wearing or use of any aids or adaptations which are normally or could reasonably be worn or used.
Activity 9 considers the ability to maintain continence of bladder or bowel, or prevent leakage from a collecting device. The descriptors take into account loss of continence while a claimant is awake/conscious and the loss of continence must lead to 'extensive' leakage of urine or faeces which is likely to require the person to have to wash and change clothing.

If I qualify for this condition, will I be put into the 'no work related' activity group?
