Yes Simon but the deferrals are done on a monthly basis on dwp computer system. Therefor if you were to phone again nearer November you might be told otherwise. I first enquired late March early April for a review due this June...it was already down as being put back to 2017. Probably as the esa 50 paperwork is triggered roughly 4-6 weeks before expiry of previous prognosis date. Call in September/October you might get a different answer. However, I suspect even deferred dates could move forward (or backward) depdndant on how well or badly maximus do at sorting the backlog.
