The Church Building Act of 1818 provided funds for two new Leicester parishes, one of which was Holy Trinity. The church was built in 1838 to Sydney Smirke's classical design as the city expanded, and formed part of a new suburb. The new parish, also established in 1838, was created out of part of the parish of St Mary de Castro Church. In 1872, Holy Trinity was completely redesigned by Samuel Sanders Teulon in a High Gothic style, with spire and side turrets in red-purple brick with limestone decoration. During the 19th century the church had wooden pews and a single central aisle, with balconies on both sides of the church; the central aisle was occupied by the middle classes and the balconies by their servants. Access to ground floor was via the main church entrance, with two side entrances for the balconies.

Buildings
A significant building project was carried out in 2018–2019, resulting in a reordered building, including main worship space, and entrance area that incorporates a coffee house. The existing balcony has been extended with new stairs within the Chancel, and the stage area has been reordered. The chancel end wall has five arched stained glass windows featuring contemporary designs of the Parable of The Sower, above which there is a more traditional floral design including an emblem of the Trinity, with smaller windows featuring "The Truth" and "The Life", but there is not a window depicting "The Way". The chancel marble end wall also features a depiction of the Last Supper. The pipe organ was transferred to a church in the Netherlands in mid-2018. The church and nearby buildings are now part of the New Walkconservation area.
Present
Holy Trinity is a Mission-Shaped church, where church members belong to mid-sized Mission Shaped Communities based around geographical locations, social networks or interests. Holy Trinity states that its vision is to "be a community that glorifies God by transforming Leicester and beyond." The church community is made up of a range of different ages, including many children and young people and a large population of University Students. Holy Trinity is also connected with the ministry of the Charismatic Evangelical movement New Wine and John McGinley, the Vicar, is New Wine's designated leader of Church Planting. The church is actively involved in outreach into the local communities in Leicester including an expanding ministry to the city's Homeless called "Triangle". Holy Trinity runs the Alpha course throughout the year as well as a multimedia and arts table-talk style event called "Questions", pioneered by the previous vicar, Roger Morgan. The Sunday services follow a theme during each term. The morning services are family-oriented with music by a live band, and the evening tends to attract more students and young adults. At each service the sermon is recorded and later made available as a podcast; sermons can be downloaded individually from the church website in MP3 audio format. Average attendance at the Sunday services totals 500.
