A worker died at a Mace data centre construction site in north-west London on Saturday (23 August).
Emergency services were called to the site, on the North Circular Road in Neasden, at 9.23am, where Mace is working on a facility for Pure Data Centres.
A London Ambulance Service spokesperson said: “We sent resources to the scene, including an ambulance crew, paramedics in fast response cars, an incident response officer and paramedics from our hazardous area response team.
“Very sadly, despite the best efforts of our crews, a man was pronounced dead at the scene.”
A Mace spokesperson said the man was employed by another contractor at the site.
They added: “We share our deepest sympathies with their family, friends and colleagues.
“We are supporting the emergency services and Health and Safety Executive with their investigations.”
A Health and Safety Executive (HSE) spokesperson said that the regulator was aware of the incident and making enquiries, although police have primacy in fatal incidents.
The Metropolitan Police has been contacted for comment but had not replied before this article went live.
In November, Pure Data Centres announced work was complete on the groundworks and substructure at the facility, which is being built next to one it already operates.
Figures from the HSE released last month showed construction remained the worst sector for workplace deaths, accounting for more than a quarter across all industries.
The 35 deaths from April 2024 to March 2025 accounted for 28 per cent of all workplace fatalities in Britain.
It was almost a third lower than the 51 construction sector deaths the previous financial year and was the lowest figure recorded since 2021/22, when there were 30 – a joint-record low.
The second worst industry for fatalities in 2024/25 was agriculture, forestry and fishing, which accounted for 23 deaths, followed by transport and storage with 15.
