Invergordon again withdrew from competition for the 2013–14 season, however, the void was filled by a new team from Dornoch in Sutherland United. That same season, a newly formed Shetland team and Lewis & Harris both registered for competition in the North Caledonian Cup. The following season, 2014–15, Shetland and Lewis & Harris also competed in the Jock Mackay Cup, while a new team, Orkney, was accepted as a member of the league – the first Islands team to be admitted. Invergordon returned a year later following a two-year period of abeyance, however, along with Muir of Ord Rovers, Sutherland United withdrew from the competition after just their second season, taking the number of competing teams down to six for season 2015–16.
