Railway Modelling Groups in Churchdown and surrounding area.

My husband and I are planning to move near our daughter and her husband, who live in Churchdown, Gloucestershire.
My husband belongs to several railway modelling groups here in West Yorkshire.
He models in EM gauge and he would like to find a group who has members who also model in this gauge. His area of interest is the Great Western Railway.
Does anyone know of any such group? Thank you.
