Afraid the 1929 Arch. Cant. (KAS) article wrongly accredits the date for the pic as 1802, but it was originally within one of Petrie's sketch books, with other churches from across the same area, dated 1807. This mis-crediting was rectified on the KAS website where it is correctly dated alongside another image of the church and one by William F. Saunders of 18th September 1856.
I agree it is a nice little church, and glad to see that after a period of redundancy it has found a new life of Christian worship.
