The rapid rise of artificial intelligence (AI) data centres in the UK is raising alarm bells among builders and housing advocates, who argue that proposed government measures may further exacerbate the ongoing housing crisis. As the demand for electricity surges, the prioritisation of AI infrastructure over new homes could effectively halt residential development across the country.
Electricity Demand Soars
Recent government proposals aim to tackle the pressing issue of soaring energy demands driven largely by a burgeoning number of AI data centres. Currently, all new infrastructure projects—including hospitals and industrial sites—must navigate a lengthy queue to secure an electricity connection. In the first half of 2025 alone, this queue expanded by a staggering 460%, primarily due to the voracious energy needs of data centres, leaving many essential projects waiting years to commence.
Under the new proposals, projects that promise significant economic growth and job creation would be allowed to bypass this queue. However, this has sparked concern from the Home Builders Federation (HBF), which cautioned that such a move could create a de facto “moratorium” on new housing developments.
The Impact on Housing
The HBF has voiced strong objections to the prioritisation of energy-intensive data centres over essential housing projects. Steve Turner, the executive director of HBF, expressed frustration at the current regulatory environment. “As we continue to face a housing crisis, it is disheartening that planning and policy frameworks favour energy-intensive data centres instead of energy-efficient homes for families,” he stated.
In December, members of the London Assembly highlighted the pressing reality that some housing developments in west London had already experienced delays due to electricity grid capacity issues. The Planning and Regeneration committee noted that the situation is becoming increasingly untenable, as the queue for connections grows longer, jeopardising the availability of new homes when they are most needed.
Future of Data Centres and Energy Grid
The situation is compounded by the fact that there are already nearly 500 operational data centres across the UK, responsible for managing a wide array of digital services from banking to online gaming. Collectively, they account for approximately 2% of the nation’s electricity consumption. However, projections suggest that the electricity demand from these facilities, driven by the growth of AI, could increase by as much as six times by 2050.
The energy regulator, Ofgem, has previously warned that the current queue for electricity connections has surpassed even the most ambitious forecasts for future demand. Many of the projects in line for connections remain speculative, lacking adequate financing, planning permission, or land rights to become viable. This raises concerns that genuine housing projects, which could foster local job creation and economic growth, are being sidelined.
Government’s Response
In light of these challenges, the government is considering measures to prioritise what it deems “strategically important” projects, including AI infrastructure, electric vehicle 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 HBF remains sceptical about the implications of these reforms for housing development, underscoring the need for a balanced approach that addresses both energy demands and housing shortages.
Why it Matters
The debate over energy prioritisation has far-reaching implications for the UK’s housing landscape. As the government seeks to foster technological advancement and economic growth through AI data centres, it must not lose sight of the critical need for affordable housing. The current trajectory risks entrenching the housing crisis further, leaving families without suitable homes while prioritising energy-intensive infrastructure. Striking a balance between innovation and residential development is crucial for ensuring a sustainable future for all.
