Hi OB, I'm glad you have had a favourable decision
As you know, ESA is an indefinite award but there should be a review date on your DLA file. Maximus do not make the decision and do not have access to it, so the only way you can find out is to contact DWP.
Under normal circumstances (ie when assessments are not suspended due to backlogs) the longest period between reassessments, for claimants in the Support Group, is 3 years.
