Holy Trinity Brompton

Holy Trinity Brompton, known simply as HTB, is an Anglican church in London founded in 1829. Its influence runs far past its size. HTB is where the Alpha course was developed, the evangelism tool that has introduced millions of people worldwide to Christianity. Under vicars Sandy Millar and Nicky Gumbel, HTB became the largest church in the Church of England and the engine of a church planting movement that has revitalized dozens of dying parishes across the UK. Archie Coates, who previously led HTB's first plant outside London at St Peter's Brighton, became vicar in September 2022.

HTB reaches 159,255 combined followers across three platforms, the second largest total among churches ranked 81 through 90. YouTube anchors the presence with 83,700 subscribers on @htbchurchlondon, growing 8 percent over the past year with an upload as recent as June 8, 2026. Instagram adds 50,511 followers on the htbchurch account and Facebook contributes 25,044. There is no TikTok account. The Alpha brand accounts, which are substantially larger, are not counted in these totals.

HTB's profile is breadth and steadiness rather than speed. The breadth score of 82.5 reflects consistent activity across three platforms, while the velocity score of 31 is on the lower end for this group. Eight percent YouTube growth on an 83K base is respectable, just not fast. The more interesting fact is what these numbers exclude. HTB's real digital influence flows through Alpha and its network of planted churches, none of which appear in this count. The church accounts alone still earn a top 100 spot, which says something about how much weight the HTB name carries on its own.
