The UK government’s latest proposals to prioritise artificial intelligence (AI) data centres for electricity connections are raising alarm among builders, who argue that this could effectively halt new housing projects. With a staggering 140 data centres currently awaiting electrical supply, the implications for the housing market are profound.
A Growing Demand for Energy
In a bid to meet escalating demands for energy, particularly driven by AI technologies, the government is considering a system that allows high-potential projects to bypass the existing waiting list for electricity connections. This queue has ballooned by an extraordinary 460% in the first half of 2025, largely due to the power-hungry nature of data centres. As a result, essential infrastructure projects, ranging from hospitals to new homes, may experience delays of several years.
Energy regulator Ofgem has expressed concern over the burgeoning queue, noting that demand has surpassed even the most optimistic forecasts. Many of the data centres vying for connection are described as “speculative,” lacking the necessary financing or planning permissions to proceed. This, they warn, could impede genuine projects poised to create jobs and stimulate local economies.
Prioritising Economic Growth Over Housing
Under the proposed reforms, projects deemed “strategically important”—including AI infrastructure and electric vehicle charging hubs—would receive preferential treatment. 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, the Home Builders Federation (HBF) has voiced strong objections, arguing that housing developments have been overlooked in this prioritisation. Steve Turner, the executive director of HBF, highlighted the ongoing housing crisis, stating, “It is frustrating that regulatory, planning and policy arrangements effectively prioritise energy-intensive data centres over energy-efficient homes for families.” He warned that without a focus on housing, the situation could lead to a “moratorium” on new homes in regions where electricity supply is already constrained.
A Tipping Point for Housing in London
The situation is particularly critical in London, where the Planning and Regeneration Committee has noted that some housing projects in west London have already been stalled due to grid capacity issues. This has raised concerns that the prioritisation of data centres could further exacerbate the housing shortage in the capital, leaving families without adequate living spaces.
The UK currently hosts nearly 500 data centres, which account for approximately 2% of the nation’s electricity demand. As the AI sector burgeons, the energy consumption of these facilities is projected to increase by as much as six times by 2050. This rapid growth exacerbates competition for limited grid resources, further complicating the landscape for housing development.
Why it Matters
The government’s approach to prioritising AI data centres over new housing developments could have far-reaching consequences for the UK’s housing crisis. As families struggle to find affordable homes, the decision to favour energy-intensive projects threatens to exacerbate an already critical situation. Balancing the demands of technological advancement with the urgent need for housing is essential for ensuring a sustainable future where both innovation and community needs are met. The implications of these policies will be felt for generations, making it imperative for policymakers to consider the broader impact on society.
