The UK faces a potential housing crisis as new government proposals may prioritise artificial intelligence (AI) data centres over residential developments in the race for electricity connections. With an unprecedented surge in demand for power, particularly from energy-intensive data facilities, builders warn that this shift could effectively halt new housing projects across the nation.
Surge in Demand for Electricity Connections
Recent statistics indicate that the number of projects awaiting electricity connections in the UK has skyrocketed, increasing by 460% in the first half of 2025. The vast majority of this demand stems from AI data centres, which have surged to the forefront of energy consumption. This dramatic rise has left other essential infrastructures, including hospitals and residential developments, in a long queue for power supply.
The energy regulator, Ofgem, has expressed concerns regarding this influx, noting that the current queue has exceeded even the most optimistic forecasts for energy demand. Many projects within this queue are deemed speculative, lacking the necessary financing, planning permissions, or land rights to transition into actual developments. This scenario raises alarms that genuinely viable projects, which could foster economic growth and create jobs, are being sidelined.
Government Proposals for Electricity Prioritisation
In an effort to manage this burgeoning issue, the government has unveiled proposals that would allow certain projects to leapfrog the existing queue based on their potential for economic growth and job creation. Among these “strategically important” projects are AI infrastructure, electric vehicle (EV) charging stations, and industrial sites transitioning away from fossil fuels.
AI Minister Kanishka Narayan emphasised 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.”
However, the Home Builders Federation (HBF) has raised significant concerns about the exclusion of new housing developments from this prioritisation. Steve Turner, the HBF’s executive director, pointed out the irony of prioritising energy-intensive data centres over much-needed family homes, especially amidst an ongoing housing crisis. “As we continue to face into 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 said.
Impact on Housing Developments
Data centres have already been designated as critical national infrastructure, which grants them preferential treatment in planning processes and shields them from local objections. This has raised alarms among housing advocates, who fear that if housing is not given priority, it could lead to an “effective moratorium on new homes” in areas where electricity capacity is already constrained.
Members of the London Assembly highlighted that certain housing developments in west London have been stalled due to the electricity grid reaching its capacity, illustrating the real-world implications of these prioritisation proposals.
Currently, nearly 500 data centres operate across the UK, responsible for about 2% of the country’s total electricity consumption. As the demand for AI processing power is expected to rise significantly—potentially by as much as six times by 2050—the strain on the electricity grid is only set to escalate.
Why it Matters
The potential ramifications of prioritising AI data centres over housing developments extend far beyond mere inconvenience. If housing projects continue to face delays or are sidelined altogether, the UK could find itself deepening its housing crisis while attempting to accommodate the burgeoning tech sector. As the nation grapples with energy demands and housing shortages, striking a balance between technological advancement and residential needs will be crucial for fostering sustainable growth and ensuring that all citizens have access to safe, affordable housing.
