His chapels included Robin Lane PM, Pudsey (1900), Harehills Avenue PM, Leeds (1903), Beecher Cliff UMFC, Bath (1906-7), Wesley Memorial UMFC, Bryants Hill, Kingswood(1907). The monumental porticoed Trinity UMFC, Pudsey (1899-1900) with its Sunday School (1912) was an exception to his preference for a fairly standard gothic style.
His brother Edward Oliver Dinsley (e.m. 1876; d. 1931) followed his father into the UMFC ministry.
