Managing director Neville Simpson said he hoped the business would grow quickly, and complement its offices in Luton, London and Yeovil.
The Essex branch, which will employ four staff, will be headed by Michael and Phil Roblin, who used to own Zodiac Paper in Shenfield prior to its purchase by Capital Paper.
Clarence Paper Sales, Moorgate's branch in Yeovil, will change its name to Moorgate Paper.
Its website address will change to www.moor gatepaper.com.
Moorgate Paper acquired York & Ford's Luton branch from the company's administrative receivers PricewaterhouseCoopers last month (PrintWeek, 18 March).
