Services at Carmel were conducted in the Welsh language.
The history of the church can be traced to the 1870s when prayer meetings and Sunday Schools were held in various chapels locally.
[1] Robert Thomas, a native of Ffestiniog, was minister from 1882 until 1905, when he died aged 52.
[2] Thomas was active in public life and spent twelve years as a member of the Pontypridd Board of Guardians.
The chapel has suffered from subsidence caused by mining subsistence.
