hi ppl, have just had handbrake adjusted for mot (02 fabia) drove home, straight road 18 mile ish and not much braking needed,and rear o/s wheel was very hot ?. will  i need to take it back

Yes sounds like a stuck on brake!

Could be they over tightened the handbrake.

Could be stuck caliper, pad or one of a number of issues.

As is was OK before and hot after, take it back as they've obviously done something to change it.

Why did you have the brakes adjusted?
