Clutch problem

[WM-S12]

Only today after a long trip I noticed my clutch goes in fine but sometimes it gets stuck just above where the biting point is.

Then occasionally it'll pop back to normal on either the two factors, one being letting it do it by itself or secondly tapping at the clutch pedal with your toe. ( i.e it doesn't sit level with the brake or accelerator pedals and makes a annoying thumping noise 1-2 seconds after changing gear <<< sometimes it just gets stuck )

I'm guessing something to do with the clutch but the clutch is only just 2 years old, it's not a con thing about the car is it. That the clutch tends to go every couple of years. ( Just frustrating knowing I might have to hike on foot over 2.5 miles in a day and at bloody after midnight in Scottish weather )
If anyone has a relative idea on what's wrong then fire them on, but my last clutch cost £215 supplied and fitted....so any help knowing where to look than my local garage would be a big bonus.

Cheers
