Good luck with whatever that is, Dave. Blue badge is pretty easy and there's usually plenty of good signage. I don't know the rules these days but in years gone by one could park on a single or double in most, but not, all places.
That is what I thought, but not so.
If there is also a small yellow stripe on the kerb then blue badge CANNOT park there at any time.
Unfortunately town centre has those stripes virtually everywhere eg I cannot get to specsavers in town as EVERY kerb for 100s of yards has them.
