Task done for pleasure, not reward (6,2,4)

I believe the answer is:

labour of love

(Other definitions for labour of love that I've seen before include "Work performed voluntarily without hope of material reward" , "Task done for pleasure not money" , "Task undertaken for enjoyment" , "Task one enjoys" , "One not undertaken for advantage" .)

I've seen this clue in The Guardian.
