A Wesleyan Society is noted in Barton-upon-Humber from at least 1760. The current Trinity Methodist Church was predated by an earlier chapel on this site, built by the Wesleyan Society and opened on 9 October 1816. The society had 46 members in 1816. This number had increased to several hundred by 1839 and the original chapel was enlarged. This first chapel was demolished by 22 May 1860 and the current building was constructed in its place, opening in early 1861.
