Horace Edward Griggs is commemorated at St. Andrew’s Church, Ilford. The memorial takes the form of three stained glass windows: the first depicts the figure of a man dressed in a university gown with Oxford University spires in the distance; the second window depicts the figure of Christ seated with an orb in his left hand; and the third window depicts a figure in officer's uniform with a helmet and map.
An epitaph to Horace Edward Griggs is divided into three parts at the foot of each window.
