National estimates for the number of reassessments we expect to be carried out each quarter are quoted in the 'Personal Independence Payment—Reassessments and Impacts' briefing note, which can be found at: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/180964/pip-reassessments-and-impacts.pdf This document has not been updated yet, following the decision to use a controlled roll out of reassessment to certain postcodes on 28 October, as we plan to update it following the autumn statement. However, we estimate that the postcodes included in the Department's Quick Guide to PIP will account for a quarter of the estimated reassessment volumes.
