John Richards, sought to provide additional church accommodation for the outlying parts of the parish.

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.

[4] 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.

[4] Construction began in 1821 and the completed church was consecrated by the Bishop of Gloucester and Dean of Wells, the Right Rev.

[9] The work included the removal of the galleries in the north and south transepts and the raising of the holy table.

[10] Another restoration of the church was carried out in 1914, owing to a defective roof and settlement of the walls, which had resulted in dampness and fungoid growth within the interior.

[12] The restoration plans were drawn up by the Diocesan surveyor Percival Hartland Thomas and the church was reopened by the Bishop of Bath and Wells, the Right Rev.

[16][17] For the second phase of work, the church council were successful in obtaining a £120,000 grant from English Heritage among other donations and a Diocesan loan.

The church's entire exterior was then refurbished and repaired, including the cupola, clock and western porch.

In 2014, the final phase of work was completed, which saw the interior refurbished and improved with new heating, new lighting and electrical rewiring.

[16][17] Holy Trinity is built of rendered Wedmore stone, with freestone dressings and a slate roof.
