English town ultimately counted cost of untilled ground (6,9)
I believe the answer is:
sutton coldfield
'english town' is the definition.
(suburban Birmingham town)
'ultimately counted cost of untilled ground' is the wordplay.
'ultimately' suggests the final letters.
'ground' is an anagram indicator ('grind' the letters into a new form).
The last letter of 'counted' is 'd'.
'd'+'cost'+'of'+'untilled'='dcostofuntilled'
'dcostofuntilled' with letters rearranged gives 'SUTTON COLDFIELD'.
(Another definition for sutton coldfield that I've seen is " somewhere in the Midlands".)
