The UK government’s latest proposals to prioritise artificial intelligence (AI) data centres for electricity connections may severely hinder the construction of new homes, builders warn. As the demand for energy surges, particularly from these power-intensive facilities, the housing sector is raising alarms about the implications for the ongoing housing crisis.
Growing Demand for Electricity Connections
A staggering 140 data centres are currently awaiting new electricity connections in the UK, with the queue for these connections swelling by an alarming 460% in the first half of 2025. This surge is primarily fuelled by the insatiable energy needs of data centres. As a result, numerous essential projects—including hospitals and housing developments—are facing extended delays, some stretching into years.
Recent proposals from the government suggest that projects promising significant economic growth and job creation could bypass this queue. However, this has sparked a backlash from the Home Builders Federation (HBF), which argues that ignoring housing developments in these considerations effectively amounts to a moratorium on new homes.
Concerns from the Home Builders Federation
The HBF has voiced serious concerns regarding the prioritisation of energy-intensive data centres over housing projects. Steve Turner, executive director at HBF, expressed frustration, stating, “As we continue to face into a housing crisis, it is disheartening that regulatory, planning, and policy arrangements effectively prioritise energy-intensive data centres over energy-efficient homes for families.” He warned that without prioritising housing, the current situation could lead to a stagnation in new home builds, particularly in areas where grid capacity is already strained.
Data centres have been classified as critical national infrastructure, allowing them to bypass local objections during the planning process. This designation has, according to Turner, exacerbated the existing challenges in the housing market, blocking essential developments and further entrenching the crisis.
The Broader Implications
The issue has gained traction among policymakers, particularly in London, where the Planning and Regeneration committee noted that new housing projects in west London have been put on hold due to grid capacity limits. With nearly 500 data centres currently operational in the UK, accounting for 2% of the nation’s electricity demand, the anticipated growth in AI could see this demand explode, potentially increasing six-fold by 2050, according to the national grid operator.
This burgeoning energy demand raises significant concerns about the long-term sustainability of both the energy sector and the housing market. The regulator, Ofgem, has already indicated that the queue for electricity connections has surpassed even the most ambitious demand forecasts, predominantly driven by AI data centres. Some projects in the queue remain speculative, lacking adequate financing or planning permissions, further complicating the landscape for genuine housing developments.
The Government’s Response
In light of these challenges, the government is consulting on allowing “strategically important” projects, including AI infrastructure, to bypass the queue. This move is part of a broader strategy to bolster the UK’s economic growth and harness the potential benefits of AI technology. AI Minister Kanishka Narayan stated, “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.”
However, this approach raises critical questions about the balance between economic growth and societal needs, particularly in addressing the housing crisis. As the government moves forward with these proposals, the tension between the tech sector’s demands and the pressing need for new homes remains a contentious issue.
Why it Matters
The government’s prioritisation of AI data centres over housing developments could have far-reaching consequences for the UK. As the housing crisis deepens, the potential for a significant slowdown in new construction poses a threat to families in need of homes. Balancing the energy needs of an expanding digital economy with the urgent requirement for affordable housing is not just a logistical challenge but a moral imperative. The decisions made today will shape the future of communities across the country, impacting countless lives.
