The UK government’s latest proposals to prioritise artificial intelligence (AI) data centres in accessing the electricity grid have raised alarm bells for the housing sector. As builders warn of a potential “moratorium” on new home developments, concerns mount that the ever-increasing energy demands of data centres could stifle essential housing projects at a time when the country faces a housing crisis.
The Surge in Demand for Electricity
Recent reports indicate that there are currently around 140 data centres awaiting new electricity connections across the UK. As the demand for energy continues to escalate—particularly due to the explosive growth of AI technologies—the situation has become increasingly precarious. In the first half of 2025 alone, the queue for electricity connections grew by a staggering 460%, predominantly driven by power-hungry data centres. This dramatic increase has led to some projects facing waits of several years before they can commence operations.
Under new government proposals announced recently, projects deemed to foster significant economic growth and job creation may be allowed to bypass this extensive queue. However, the Home Builders Federation (HBF) has voiced strong objections to this approach, stressing that prioritising data centres over housing developments could effectively halt new home building in the UK.
Concerns from the Housing Sector
The energy regulator, Ofgem, recently cautioned that the queue for electricity connections has surpassed even the most optimistic projections for future demand. Much of this surge has been attributed to AI data centres, with Ofgem highlighting that many of the projects in the queue are merely speculative at this stage. This means that while they may receive a connection, they are often lacking the necessary funding, planning permissions, or land rights to transform these plans into tangible developments.
Steve Turner, executive director at HBF, articulated the frustration felt within the housing sector, stating, “As we continue to face a housing crisis, it is frustrating that regulatory, planning, and policy arrangements effectively prioritise energy-intensive data centres over energy-efficient homes for families.” He warned that neglecting housing developments in favour of data centres could result in a de facto halt on new housing in areas where the electricity grid is already under strain.
The Critical Infrastructure Debate
Currently, data centres are classified as critical national infrastructure, allowing them to bypass local objections that might otherwise impede their development. This status has led to fears that the needs of the housing sector are being overshadowed. London Assembly members have highlighted that some housing projects in west London have already experienced delays due to electricity grid capacity issues, reinforcing the urgent need for a balanced approach to infrastructure planning.
With nearly 500 data centres operating across the UK, they are responsible for approximately 2% of the nation’s electricity consumption. As the demand for AI capabilities continues to surge, the energy requirements of these facilities could increase by as much as six times by 2050, according to projections from the grid operator. This growth presents a formidable challenge to the already strained energy infrastructure.
A Shift in Priorities
In light of these developments, the government is consulting on measures that would enable “strategically important” projects—including AI infrastructure and electric vehicle charging hubs—to skip the electricity connection queue. AI Minister Kanishka Narayan has expressed optimism about 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.”
Yet, the persistent concern remains that without a concerted effort to prioritise housing developments, the construction of much-needed homes could be severely hampered.
Why it Matters
The intersection of energy demands from AI data centres and the urgent need for new housing represents a critical juncture for the UK. As the government grapples with balancing economic growth and the housing crisis, the decisions made now will have lasting implications. Prioritising data centres at the expense of residential projects could exacerbate the already dire housing shortage, leaving families in limbo while the country’s energy landscape undergoes seismic shifts. The challenge lies not only in meeting energy demands but also in ensuring that the basic need for housing is not sidelined in the process.
