People who claim Personal Independence Payments (PIP) or who were denied the benefit entirely could be entitled to backpay following a new review by the Department for Work and Pensions (DWP).
The DWP is looking into past claims made by deaf or hearing impaired people following a decision by the Upper Tribunal.
It relates to whether people who are deaf or hearing impaired are considered to be able to wash or bathe safely, as part of the PIP assessment.
