That depends on whether you are getting
contributary or
income related ESA. Contributary is given to claimants who have made enough NI contributions in the last 2 full tax years, also to people being migrated from IB. Income-related ESA is paid to those who do not have enough NI contributions in the qualifying years and meet the means testing.
People on contributary ESA in the WRAG will be means tested after 365 days. Time in the Support Group is not limited
12 Month Limit for ESA(CB) These are the rules for income-related ESA
Asset rule for ESA(IR) 24 hour work rule for ESA(IR) I hope this helps.
