It look's to me like the boot has been gripped when putting the shaft on, which as then pushed it inwards so is most likely rubbing, either get it back to the garage that did the job, or undo the outer clip and then try to put the shape back, add new clip after.
Thank you Arctic2. Just called the blokes and next appointment is Tuesday, so got booked in, but might get under the car and see if I can get it sorted. Have a new boot somewhere in the attic which should have a new clip.
Quick update on that one. Was at the garage last week, they checked and said all would be ok, air got sucked in sometimes.
Sounds a bit odd. Didn't have the chance to take the wheel off yet to see.
