Gridley was the son of Edward Gridley of Abbey Dore in Herefordshire. He worked as a consulting engineer but later turned to politics.

The latter year he was raised to the peerage as Baron Gridley, of Stockport in the County Palatine of Chester.

Lord Gridley married Mabel, daughter of Oliver Hudson, in 1905. He died in July 1965, aged 87, and was succeeded in the barony by his eldest son Arnold.
