There is a brief listing in English Heritages’s inventory which lists a chapel of 1850 in Ickleford. I think this is it as it is along a footpath called Chapel Walk west of the Arlesey Road at the correct grid reference. It closed in 1978 and was sold in 1979 and is now somewhat altered as housing.
In suburban Hemel Hempstead. Opened in 2015, this church replaced a town centre building demolished in 2014 and an older building on this site. The worship area is at one end as part of a larger development of ancillary rooms by Life Build Solutions.
This range of buildings was the town’s Methodist complex from 1824 to 1841. Ashbrittle House on the left was a schoolroom, Dagnall House in the centre was the Chapel and Canon House was the Minister’s House.
