Here's your grandfather aged 4 (with George Henry Brand aged 33) in 1911.
"England and Wales Census, 1911," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:X7BY-F6L : accessed 7 April 2016), Edward Frank Brand, Brighton, Brighton, Sussex, England; from "1911 England and Wales census," database and images, findmypast (http://www.findmypast.com : n.d.); citing PRO RG 14, The National Archives of the UK, Kew, Surrey
I can't upload the image from work so you'll have to wait until this evening unless another subscriber to findmypast wants to do it. Also in the household were Emma Clara Brand (29) and kids George, Ettie, Elizabeth, Louise and Reginald.
