The law is changing from 15/2/2022. Rather than being at the discretion of the work coach, there will be a specific exemption from the requirement to accept a claimant commitment, for those classed as terminally ill.
The government say-
'7.1 To be entitled to receive Universal Credit (UC) and New Style Employment and Support Allowance (NS ESA) a claimant is legally required (as per UC 2013 and ESA 2013 regulations) to accept a claimant commitment. The exemption to have an accepted claimant commitment was designed to allow for exceptional circumstances where it would not be appropriate to apply.'
The time period in the defnition of terminal illness will be increasing from 6 to 12 months, probably at some point this year. This will be for issues such as this and others like PIP, AA and DLA claims and getting in the support group.

claimant commitment.
