A grandfather died after falling through a hole in his bathroom left by workers.
Kenneth Armitage, 81, fell through an unguarded hole created during a wet room conversion by Cooper and Westgate. He was found dead the next evening.
HSE found the company failed to secure the hole, train employees, and undertake a risk assessment or method statement.
Cooper and Westgate Co. Ltd pleaded guilty to breaching Sections 2(1) and 3(1) of the Health and Safety at Work etc. Act 1974. The company was fined £150,000 and ordered to pay £50,000 in costs.
Inspector Yolande Burns-Sleightholme warned that employers must assess and control work-at-height risks, secure holes effectively, and train employees to prevent such tragedies.
