The Disability News Service (DNS) is reporting that the number of complaints about personal independence payment (PIP) assessments rose by nearly 900% in the course of a single year.
Figures obtained by MPs, and cited by DNS, show that the number of complaints went up from 142 in 2015-16 to 1,391 in 2016-17.
The number of complaints that were upheld in the same period rose from 67 to 545.
There was not a corresponding rise in the number of PIP assessments completed over the same period, suggesting either that something has changed in the way assessments are carried out or that claimants are now much more willing to make a formal complaint.
DNS have been carrying out an investigation into PIP assessments and have now heard from 250 claimants who say that their assessment reports were dishonest.
The allegations involve both Capita and Atos staff.
