One in four people in Coventry receiving disability benefits have had their payments stopped by assessors, as part of the roll-out of a new systemCharity Scope said that many disabled people are "losing out on vital support" under the new system, which it says is beset with problems.
Since 2013, the Government has been moving claimants from Disability Living Allowance to the Personal Independence Payment.
The DWP decide how much to award based on a "how your disability affects you" form and a points score from the face-to-face assessment, as well as any supporting evidence that the claimant provides.
In Coventry, 24 per cent of Disability Living Allowance claimants failed the assessment for PIP.
According to the Department for Work and Pensions, 8,115 people in Coventry have applied to switch from DLA to PIP since it was introduced, and 1,984 of them were rejected after a face-to-face assessment.
Since the beginning of the PIP roll-out, the DWP has also rejected 228 people for missing their assessment appointment.
A further 437 people were turned down because they did not send in the correct form on time.
Scope said that it regularly speaks with disabled people who are put off by the complexity and stress of applying for PIP.
A spokesperson said: “It is deeply worrying that so many disabled people are losing out on vital support when being reassessed for PIP.
"The entire system needs to be much more focused on the needs of the individual.
"With record levels of appeals against decisions successful, the whole decision making process is beset with problems."
In 2017, a survey by Disability Rights UK found that many claimants thought that the face-to-face assessment was "a punishing and traumatic process".
Survey respondents said that assessors were "ill-informed and not suitably knowledgeable of the disability they are preparing to assess".
