Jersey Gas Workers Face Manslaughter Charges Over Fatal 2022 Explosion

Three gatekeepers who cut the wrong pipe in a Jersey gas network have been charged with gross negligence manslaughter following a December 2022 blast that killed ten residents. On the eve of a tragic blast that claimed the lives of ten residents at Jersey's Haut du Mont flats, a court heard that the gas work carried out by three workers was not merely negligent but profoundly flawed. The workers, Lee Ward aged 59, Neil Armstrong 58 and John Wright 60, each pleaded not guilty to ten counts of gross negligence manslaughter in relation to the December 10, 2022 explosion. The case is being presented alongside a health and safety claim against the gas supplier Island Energy, whose chief executive Graeme Millar has also pleaded not guilty to two counts of failing to keep people safe. The prosecution's case hinged on a series of failures in the planning and execution of a planned gas disconnect that preceded the tragedy. Prosecutor Simon Thomas explained to a bright‑skied courtroom that well‑intended maintenance work left in the dark an entire network of pipes that fed the Haut du Mont flats and several adjacent buildings, including the St Helier Yacht Club and Island Energy's own premises. In early December, the three workers - funded by Island Energy and mobilised by an Andium Homes request - cut a pipe that, according to the prosecution, was the wrong one. Their errors were not merely technical but systematic: they misidentified the location of a critical T‑shaped branch and made hasty cuts without the proper excavation or testing that the company's own procedures require. These mishandlings, the court heard, did not directly cause the explosion but set the stage for it. By cutting the wrong pipe, the workers unintentionally left a corridor of unisolated gas flowing through still‑connected lines. When the Yacht Club's system was later cut to address the wrong section, gas carried on the same conduit back up into the Haut du Mont network, unbeknownst to the workers. They tried to shut down gas in the flats, but the cuts had severed the safety valves R. The illegal approach ran along the granite wall, cutting under the street without proper supervision or verification. The prosecution described how the men had "guessed" the pipe locations rather than conducting mandatory pressure tests. The result was a disjointed network with a complete lack of redundancy to isolate the flats, culminating in the fatal task of re‑injecting gas into a system that had been left in a precarious state. Island Energy's own internal procedures were cited as another layer of negligence. The company's safety manager had highlighted deficiencies in the supervising staff's training, the lack of a clear emergency response plan for the area, and a culture of staff "pressure" to expedite the restart of services at the Yacht Club. The company also failed to ensure that the "shoe‑horn" methods used to label pipe routes were adequate. Combined, these factors formed a narrative of a company that had ignored its own health and safety obligations, leaving a street‑level network still live with gas when the general house‑holder customer had already gone off gas. The court concluded that the forethought that had been absent was absolute: Ionised gas remained linked to the off‑line mechanisms, and the crew's hasty re‑insertion of pressure into the system was illegal at every step. The case has just opened into the heart of Jersey's new Royal Court Rooms at Jubilee Wharf, a fresh and yet familiar venue for the seriousness of the incident. The defense claims that the workers were following orders and that unforeseeable complications resulted from a unique set of property conditions. The prosecution, however, will seek to make the point that the pattern of oversight - from Island Energy's capital budget to the training heuristics - shows a legal failure in several layers. Essential for the jury is whether the steps taken to isolate the network were adequate and whether the decision to reroute gas without full verification violated safety protocols. The verdict, if reached after the predicted two‑month hearing, will hold entire teams accountable for an incident that ended ten lives and shook the island's sense of security. No doubt the outcome will reverberate across regulatory frameworks for utility management in Jersey. The court will have to decide if the negligence was purely operational or if a systemic lack of safety mechanisms contributed to the failure, and, if so, how to remedy it for a population that depends on reliable, safe supplies of essential services
