Hi Sarahjohn
ESA/LCWRA are indefinite awards with scheduled reassessment based on the Prognosis Date completed by the assessor in their report, so your existing LCWRA award continues in payment until a new Decision is made.
Most claimants will usually have a review every 2 - 3 years, we have heard from members who have not been reassessed in over 10 years,so to answer your question, I have no idea.
