Work and Pensions Secretary of State Amber Rudd announced in March that people receiving PIP who have reached State Pension age will no longer have their awards regularly reviewed, instead moving to a light touch review at 10 years. Nearly 290,000 people of State Pension age are in receipt of PIP.
This has been rolled out for new claimants to PIP whose review would have been scheduled after they had reached State Pension age will receive an ongoing award with a light touch review at 10 years.
