“how does that work”?
Basically, if you have PIP for two years then you’ll get the review documentation some months in advance of the ‘expiry’ date on your award. This consists of a form asking you about any changes that have occurred in how your disabilities affect you. You have 30 days to return the form and also enclose any recent evidence you want to be considered with it. There will then be an assessment of whether a decision can be made or whether another face to face assessment is needed. If an assessment is needed then the process is pretty much the same as your original assessment.
Having just gone through the review process I found it at least as taxing and upsetting as the original transfer from DLA. If you have an assessment just remember to request a copy of the report from the DWP a few days after your assessment and don’t accept what Independent Assessment Services say about waiting for the DWP decision letter. This is just to put people off seeing the report in time to challenge it.
On what will happen with PIP it may become means tested but that may not raise as much money as the whole fiasco has cost. However, I’m pretty sure the tax-free status of it will bite the dust fairly soon. It requires no additional workforce for checking, as means testing does, and the HMRC would be collecting the proceeds. The DWP is, I think, on borrowed time as a separate department and savings could be made by making the DWP part of the Treasury and ‘streamlining’ the benefits and tax systems. Interesting times indeed!
