Most PIP awards last for fixed periods; the end date is stated in your decision letter. However, the DWP has discretion to contact claimants to review a PIP claim, even if the PIP award still has several years to run.
Short-term awards of PIP for up to two years are given where the claimant is expected to improve significantly.
Awards of 5-10 years are made where changes in the claimant’s condition are possible but less likely.
In summer 2018, the DWP announced that claimants who are awarded the highest level of award under PIP - and who have severe or progressive conditions where their needs are expected to stay the same or increase - will receive an ongoing award of PIP with a 'light touch' review every ten years.
Before your award ends, you will be invited to apply to renew your claim. You may be asked to complete a PIP review form (AR1), which is much shorter than the PIP2 form completed by new claimants and focuses on changes in your circumstances, Alternatively, you may be asked to complete the PIP2 form again.
On September 6th 2022 the DWP announced that the automatic extension period for existing PIP awards awaiting review would be up to 12 months, it had been 3 months, and that from October 31st 2022 they would write to claimants affected explaining this. Until October 31st they would continue with the existing practice of informing them by text. The extension is because they are struggling to deal with the number of new claims.
