On 7 February 2015, with Newport County in sixth place in League Two, Edinburgh was appointed manager of League One club Gillingham, with Gillingham paying Newport compensation as Edinburgh was under contract. Edinburgh led the Gills to a 12th-place finish in the third tier of English football, after a poor start to the season led to the sacking of former manager Peter Taylor on 31 December. Gillingham had won just three of their first 15 league games, and were sitting 20th in League One, just two points above relegation.
