Two Wiltshire companies have been fined after admitting safety breaches which resulted in the death of a worker.
TH White Installations of Devizes and RF Stratton and Company, owners of Manor Farm, Kingston Deverill, Wiltshire, were fined £35,000 each.
Swindon Crown Court heard on Friday that engineer Timothy Kynaston, 50, fell eight metres through a rooflight while working at the farm in 2004.
He fell from a walkway which had no safety measures in place, it was said.
Health and Safety Inspector Andy Shaw said: "Employers need to be aware of the dangers and take appropriate action to reduce the risks before an incident occurs.
"There is a great deal of help and guidance available to help companies get it right and a relatively small investment in good safety measures could not only save lives but also save money in the long run, especially in terms of sickness absence and enforcement action."
