Moving House

My husband just moved successfully from DLA to PIP thanks to the invaluable advise in the guides on here. He has yet to receive his first payment of PIP but we are concerned that this may all get messed up as we are planning to move house to downsize to a smaller more manageable property and live closer to our daughter for support as we get less able to cope. Has anyone experienced any problems with their PIP after moving. I have checked and lots of places say that this is not a change of circumstance that should trigger a review but nevertheless we are anxious as the whole process of applying for PIP in the first place caused my husband a lot of anxiety.
