Maintaining Limited Capability for Work Status

I was reading this example on the ESA FAQ page re the 12 month limitation of ESA (CB):

A claimant was subject to the time limitation for ESA(CB) and did not qualify for ESA(IR). They have opted to receive NI credits and have maintained their Limited Capability for Work status. At some future point in time due to deterioration of an existing condition or a new condition, they meet the criteria for the Support Group.

The claimant is placed in the Support Group and their ESA(CB) is re-instated, however, if at any time they no longer meet the criteria for the Support Group, their entitlement to ESA(CB) ceases immediately.

How does a claimant 'maintain their Limited Capability for Work status' in the above situation? Are claimants given the opportunity to send in a regular ESA50 to complete or is this done in some other way?

(Reading that all hope is not lost if one's condition deteriorates to support group level after ESA (CB) has ceased due to time limitation is a revelation to me - I have been very worried about this as I have a number of degenerative conditions. Where would we be without this site?!)

Thanks in anticipation.

This has not been made totally clear yet. We expect that claimants will be sent regular ESA50s but are not sure whether they would also have to attend face-to-face assessments periodically.

Thanks Mrs Hurtyback.

And I guess they may have to attend work focused interviews too?

No (at last, some good news!). One can only be obliged to attend WFIs while being awarded the WRAG component of ESA.

Thanks Mrs Hurtyback.

Thank goodness for that!
