The Wirral Christian Centre Missions Department promotes overseas missions and collects donations via the Elim Missions Box scheme, which are sent to the central Elim Missions Fund for use in work overseas.

The department also makes information and materials from Headquarters available to church members and promotes a missions prayer programme, with prayer partners receiving a regular prayer diary. Information about the Walker's work in Cambodia and the Pates' work in Africa is of particular interest to the church as members sponsor these families directly.

Members of the church have taken part in overseas missions, working with Elim churches and other denominations. Recent work has been done in France and in Nigeria. Pastor Epton has been leading missions teams in Nigeria for over 10 years, with recent work focussing on leading Ministers' conferences and taking part in outdoor gospel meetings.
