Holy Trinity Church was built as a chapel of ease to the parish church of St Mary in Wedmore.
As a result of the growing population of the parish during the early 19th century, the vicar of Wedmore, Rev. John Richards, sought to provide additional church accommodation for the outlying parts of the parish.
The population of Wedmore had reached over 3,000 and the parish church was only capable of accommodating 700 people.
The hamlet of Blackford was selected as the location for the first chapel of ease, which would also serve the inhabitants of Westham and West Stoughton, all of whom were approximately two miles from the parish church.

Plans for the church were drawn up by Richard Carver of Taunton, with seating for 300 people, 200 of which would be free and unappropriated for the benefit of the poor.
Construction began in 1821 and the completed church was consecrated by the Bishop of Gloucester and Dean of Wells, the Right Rev. Henry Ryder, on 29 August 1823.
Blackford was made its own ecclesiastical parish on 11 October 1844.

In 1889, a public meeting was held to discuss the replacement of the church's harmonium with an organ.
The harmonium was considered inadequate to conduct the choir and was also in a poor state of repair.
The required £100 was successfully raised and the organ, built by Mr. W. Vowles of Bristol, was opened by the Bishop of Bath and Wells, the Right Rev. Lord Arthur Hervey, on 1 August 1890.
