Specialist used it with chancel refurbishment (9)
I believe the answer is:
technical
'specialist' is the definition.
(I've seen this before)
'it with chancel refurbishment' is the wordplay.
'with' is a charade indicator (letters next to each other).
'refurbishment' is an anagram indicator (I've seen this in other clues).
'it' after 'chancel' is 'chancelit'.
'chancelit' is an anagram of 'TECHNICAL'.
'used' acts as a link.
(Other definitions for technical that I've seen before include "relating to a particular craft" , "Requiring specialist knowledge" , "sort of college" , "Scientific" , "Using specialised skill" .)
