The ongoing surge in demand for artificial intelligence (AI) data centres could severely hinder the construction of new homes across the UK, industry experts have cautioned. Recent government proposals prioritising these energy-intensive facilities may exacerbate an already critical housing crisis, as builders struggle to secure necessary electricity connections.
Surge in Demand for Electricity Connections
According to the latest figures, there are currently around 140 data centres awaiting electricity connections in the UK. The first half of 2025 witnessed an alarming 460% increase in the queue for new connections, primarily fuelled by the insatiable energy appetite of AI data centres. This surge has led to significant delays for a variety of projects, with some developers facing waits of several years before they can commence operations.
The government’s recent proposals, announced on Wednesday, suggest that projects promising substantial economic growth and job creation—such as AI infrastructure—might be allowed to bypass this lengthy queue. However, the Home Builders Federation (HBF) has voiced strong objections, arguing that this could effectively place a moratorium on new housing developments.
Concerns from the Home Builders Federation
Steve Turner, executive director of the HBF, expressed frustration over the prioritisation of data centres over much-needed housing. “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 stated, urging the government to reconsider its stance.
Currently, data centres enjoy preferential planning treatment, having been classified as critical national infrastructure. This designation allows them to circumvent local objections that typically impede other types of development. Turner warned that if housing developments are not given similar priority, it would significantly stall new projects, particularly in regions where existing electricity capacity is already strained.
The Impact of AI on Energy Demand
The rapid expansion of AI technology is expected to further increase the number of data centres across the UK. Presently, there are nearly 500 data centres operating nationwide, catering to essential digital services, from banking transactions to online gaming, and collectively accounting for approximately 2% of the nation’s electricity demand. Experts predict that the energy requirements of these facilities could potentially multiply six-fold by 2050, as the need for advanced processing capabilities continues to grow.
In December, members of the London Assembly highlighted that some housing projects had been temporarily halted in west London due to capacity issues within the electricity grid. The Planning and Regeneration committee reported that the escalating demand from data centres is already affecting the feasibility of new residential developments.
Government Response and Future Considerations
In response to these challenges, the government is considering reforms that would allow “strategically important” projects to bypass the electricity connection queue. This includes not only AI infrastructure but also electric vehicle charging stations and industrial sites transitioning away from fossil fuels. Concurrently, Ofgem is reviewing the criteria for joining the queue to ensure that genuine, viable projects are not left behind.
AI Minister Kanishka Narayan emphasised the need for swift action, 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.”
Why it Matters
The intersection of technological advancement and housing development in the UK presents a critical challenge. As the government weighs the future of infrastructure investment, the prioritisation of data centres over housing could exacerbate an already pressing crisis. With the nation facing a significant shortage of homes, the potential for new developments to be sidelined in favour of energy-intensive facilities raises urgent questions about the balance between economic growth and social responsibility. The decisions made in the coming months will not only shape the future of the UK’s digital economy but also determine the living conditions for countless families.
