An investigation by the Health & Safety Executive (HSE) found that Mullberry Homes Limited failed to plan, manage, and monitor health and safety work on construction sites across England. Mullberry Homes Limited was given a series of notification of contravention (NoC) letters outlining how it needed to improve, with advice on doing so. It also received numerous formal improvement notices and prohibition notices due to unsafe work, yet the firm repeatedly failed to ensure the work being done on their sites. These included sites in: Aintree, Liverpool; Middleton, Rochdale and Thorncliffe Road, Barrow-in-Furness. The company failed to reach the required basic legal standards, the HSE said. The HSE investigation also found that Alistair Wilcock, in his role as managing director, should have ensured measures were taken to comply with each concern when it was raised by HSE and these measures were maintained.
