The UK government’s recent proposals to prioritise artificial intelligence (AI) data centres for electricity connections could inadvertently stymie new housing developments, builders have cautioned. As the demand for energy surges, particularly from power-hungry data centres, the growing backlog for electricity connections has reached alarming levels, raising questions about the future of housing amidst the nation’s ongoing crisis.
The Rising Tide of Energy Demand
As of now, there are approximately 140 data centres awaiting new electricity connections across the UK, a number that has surged dramatically in recent months. In the first half of 2025 alone, the queue for connections increased by a staggering 460%, primarily driven by the burgeoning needs of AI data facilities. This surge has created significant delays for various infrastructure projects, many of which could take years to launch.
Under the new proposals, projects demonstrating substantial economic growth and job creation could leapfrog the queue, effectively sidelining other essential developments, particularly in housing. The Home Builders Federation (HBF) has expressed grave concerns that this prioritisation could lead to a de facto halt on new homes, exacerbating the existing housing crisis.
The Implications for Housing Development
In November, Ofgem, the energy regulator, highlighted that the electricity connection queue had surpassed even the most ambitious forecasts for demand, largely due to the appetite of AI data centres. Alarmingly, many of these projects are merely speculative, lacking essential financing, planning permissions, or land rights necessary to transform proposals into tangible projects.
The risk here is palpable: genuine housing developments, which could provide vital jobs and stimulate local economies, are being obstructed by a prioritisation system that favours speculative AI projects.
The government’s plan aims to rectify this by consulting on the potential for “strategically important” projects—such as AI infrastructure, electric vehicle charging stations, and industrial sites transitioning from fossil fuels—to bypass the queue. This initiative is intended to streamline the integration of vital energy infrastructure while bolstering economic growth.
Concerns from the Home Builders Federation
AI Minister Kanishka Narayan has stated that timely reforms are essential for harnessing AI’s potential in fostering a prosperous and equitable Britain. However, Steve Turner, executive director of the HBF, has strongly voiced that housing developments should also be treated as critical infrastructure. “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 remarked.
Turner further warned that the lack of prioritisation for housing could lead to an “effective moratorium” on new homes in areas where electricity capacity is already constrained. This sentiment resonates particularly in London, where members of the Assembly’s Planning and Regeneration committee have noted that some housing projects have faced delays due to the electricity grid reaching its limits.
The Growing Number of Data Centres
Currently, the UK hosts nearly 500 data centres, which are integral to digital services spanning from banking to online gaming, accounting for about 2% of the nation’s electricity demand. However, with the escalating growth of AI, the need for data centres is expected to skyrocket. The electricity demand from these facilities could potentially increase by as much as six-fold by 2050, as outlined by the national grid operator.
This impending surge punctuates the urgency of balancing the energy needs of data centres with the necessity for new housing. As the government deliberates on new policies, the challenge remains: how to effectively manage the energy demands of the digital future while ensuring that housing developments are not left in the lurch.
Why it Matters
The interplay between energy demands and housing development is intricately linked to the broader socio-economic landscape of the UK. As the government seeks to embrace the potential of AI, it must also navigate the pressing need for affordable homes. The prioritisation of data centres may drive technological advancement, but if it hampers housing availability, the ramifications could be felt across communities already grappling with a housing crisis. Ensuring a balanced approach is crucial to fostering a sustainable future, one that accommodates both innovation and the basic need for shelter.
