On 31 January 2014, Moncur joined Scottish Premiership team Partick Thistle on loan. He joined until the end of the season, but was confined to appearances in the under-21 team during the early stages of his loan. He eventually made his debut as an 80th-minute substitute for Lyle Taylor in their 1–0 defeat to Inverness Caledonian Thistle on 22 March. His second and final appearance for the Jags was a goalscoring one, netting five minutes after replacing Chris Erskine in the 73rd minute of their 3–2 home defeat by Ross County on 10 May.
