The escalating demand for electricity to power AI data centres in the UK may hinder the construction of new homes, according to a warning from industry leaders. As the government proposes prioritising power connections for these energy-intensive facilities, the Home Builders Federation (HBF) has voiced serious concerns over the implications for the housing crisis, suggesting that a focus on data centres could effectively freeze new residential projects.
Surge in Demand for Electricity Connections
Recent statistics reveal that approximately 140 data centres are currently awaiting new electricity connections in the UK. This backlog has surged dramatically, with a staggering 460% increase observed in the first half of 2025. The demand is largely attributed to the ever-growing appetite for power from AI operations, which require substantial energy to function effectively.
Under proposals announced this Wednesday, the government intends to allow projects that promise significant economic growth and job creation to bypass the lengthy connection queue. While this initiative aims to stimulate the economy, it raises critical questions about the prioritisation of energy resources.
Concerns from the Housing Sector
The HBF has expressed alarm over the government’s plan, arguing that it could lead to a de facto ban on new housing developments. Steve Turner, the executive director of HBF, articulated that it is disheartening to see regulatory and planning frameworks favour energy-hungry data centres over the pressing need for energy-efficient homes. “As we continue to face a housing crisis, it is frustrating that housing developments are not considered as priority infrastructure,” he stated.
Data centres, which are classified as critical national infrastructure, already enjoy preferential treatment in planning processes, allowing them to move forward despite local opposition. Turner warned that without a shift in focus, regions experiencing capacity constraints could see a significant halt to new housing projects, exacerbating the ongoing crisis.
The Broader Impact on Energy Strategy
In a report from November, Ofgem, the UK’s energy regulator, highlighted that the queue for electricity connections had exceeded even the most optimistic projections. The regulator cautioned that many projects in the queue are merely speculative and lack the necessary financing, planning permissions, or land rights to materialise. Consequently, valuable projects that could stimulate local economies and create jobs risk being overshadowed by the demands of AI data centres.
As the government seeks to address this challenge, it plans to consult on allowing “strategically important” projects, such as AI infrastructure and electric vehicle charging hubs, to skip the line. Simultaneously, Ofgem is considering measures to refine the criteria for joining the electricity connection queue.
AI Minister Kanishka Narayan commented on the importance of these reforms, stating, “Delivering data centres relies on access to the grid. These timely reforms will help us move at pace, to seize AI’s potential to help build a wealthier and fairer Britain.”
The Impending Housing Crisis
Members of the London Assembly have already noted that the wait for electricity connections has caused delays in housing projects, particularly in areas like west London where the grid has reached capacity. With nearly 500 data centres across the country currently contributing to 2% of the nation’s electricity demand, the anticipated growth driven by AI could see this figure skyrocket. The grid operator has estimated that the electricity demand from data centres could increase by as much as six times between now and 2050.
As the government navigates the complex landscape of energy demands and housing needs, the balancing act between fostering technological advancements and addressing the housing crisis remains a formidable challenge.
Why it Matters
The potential prioritisation of AI data centres over housing developments underscores a pressing dilemma in the UK’s energy and housing strategies. As the country grapples with a housing crisis, the decision to favour data centres could stall new home construction, exacerbating existing issues of affordability and availability. Ultimately, the government’s approach could shape the future of both technology and housing, influencing the lives of millions. Balancing the needs of a burgeoning digital economy with the fundamental right to adequate housing is not just a policy challenge; it is a moral imperative that will define the UK’s trajectory in the coming years.
