It’s published by Newsquest (West Essex) from editorial offices in Epping.
Along with the Waltham Forest Guardian and the Wanstead & Woodford Guardian, it’s part of a three-title Guardian series whose rather convoluted history (with several name changes, and gained and lost editions) stretches back to 1876; the earliest mention of Epping Forest in a Guardian series title appears to be in 1942.
There’s a companion freesheet, the Epping Forest Independent. In addition, roughly a thousand copies of the Guardian are distributed free via pickup points.
It comes out on Thursdays. An e-edition (free) is also available via the website.
