The length of time that PIP is awarded is based upon each claimant’s individual circumstances. PIP awards can vary in length. The shortest award is 9 months. The longest is an ongoing award with a ‘light touch’ review at 10 years.
The letter they receive when their claim is approved will tell them when their claim will end and if it will be reviewed. We do regular checks on awards that need a review to make sure that everyone continues to receive the most appropriate level of support.
