PIP Renewal phone call

Husband just had a phone call from PIP about his PIP Renewal. He asked for high rate mobility, as he had a knee replacement last summer and has been in constant pain since. He has a blue badge and has just had a disabled parking bay marked out at the front of our house.. He has physio and hydrotherapy at the hospital, as recommended by the consultant. She also noted down his painkiller medication. The DWP advisor has included all the information to his notes and now he's got to wait approx 2 weeks to hear the result.
