No your award shouldn’t be affected.
It’s all about people with mental health conditions who claimed PIP for mobility. And the DWP will be reviewing those claims to see if more points should have been awarded, ie to pay out more money not less.
So if you were given the enhanced rate for mobility then it wouldn’t affect you (whether you were awarded it for either physical or mental heath grounds). And if you claimed on physical health grounds, then equally it shouldn’t affect you (regardless of the decision on your claim).
This means that you should be fine Paul.
Obviously, I have used the word ‘should’ throughout this post, because what the DWP ought to do and what they will actually do don’t necessarily bear much resemblance. But given that the issues this week seem very clear, and they have enough to do just reviewing the claims they have to review, giving themselves extra work would be ludicrous.
