On 1 October 2024, almost all of the former parish churches in Orkney united to create a single Orkney Islands Church of Scotland staffed by a team ministry. It is part of the Church of Scotland's Presbytery of the North East and the Northern Isles ("NENI"). As of September 2026, the parish churches of Evie & Rendall are not yet part of this new structure, but all other formerly separate parishes in Orkney have joined.

The former Presbytery of Orkney was split into the three presbyteries of Cairston, Kirkwall and North Isles in 1725. They merged back into the Presbytery of Orkney in 1929-30, with the union of the Church of Scotland and the majority of the United Free Church of Scotland.The Fasti Eccleasiae records show separate Presbyteries of Kirkwall, North Isles and Cairston in 1929. e.g. a minister was licensed by the Presbytery of Cairston on 12th June 1929. The 8th volume of Fasti records George Frederick Cox as the Clerk as the Presbytery of Orkney at March 1930. It would seem that the Presbyteries united in tandem with the Union of the Churches.

The parish has a congregation of approximately 1800, and is allocated 7 FTE staff.
