The Norfolk firm was handed down the fine, and ordered to pay £80,000 by Nottingham Crown Court, in October 2007 after one of its employees died when he fell when working on a site in Bilsthorpe.
Daniel Askew, 22, died in November 2003 when he fell 10m after leaning on an unsecured handrail on the mezzanine area of a cold store, under construction.
The work was being undertaken at the premises of Phil Hanley, in the Belle Eau Industrial Park.
Heath and Safety Executive head of operations for construction in the Midlands Rosi Edwards said: "The decision on whether to reduce fines and costs (or not) is a decision for the court, however we welcome [the] decision as it serves as a strong reminder to the construction industry.
"Falls from height remain the most common kind of accident causing fatal injuries."
