Signed for Margate in August 2007 after solid displays in pre-season friendlies. After 22 starts and 15 substitute appearances he was one of the few players who remained with the club under new management for the 2008/09 season.

Kieran started the first ten games but then found himself frequently on the sub's bench until a surprising appearance at right-back in November saw a new side to the midfielder as he slotted into the position comfortably, although injury did, eventually, restrict him to 29 appearances.

Moved to Whitstable Town on loan in December.
