The UK’s burgeoning demand for artificial intelligence (AI) data centres could severely hamper new housing projects, builders have warned. As government proposals emerge that would prioritise energy connections for these facilities, concerns are mounting that the housing crisis could worsen, with home builders facing delays that may effectively freeze new developments across the country.
Surge in Demand for Electricity Connections
Recent statistics highlight a staggering increase in the demand for electricity connections, with the queue for new supply growing by an astonishing 460% in the first half of 2025. This surge is predominantly fuelled by the appetite for power-hungry data centres, which are anticipated to dominate the energy landscape in the coming years. Currently, all new infrastructure, from healthcare facilities to industrial sites, must navigate a virtual queue for access to the electricity grid, leading to significant delays for various projects.
The energy regulator, Ofgem, has sounded the alarm, noting that the queue for electricity supply has surpassed even the most optimistic forecasts. Many of the projects currently in line are described as “speculative,” lacking adequate financing, planning permission, or land rights necessary for them to materialise. As a result, genuine projects that could stimulate local economies and create jobs are being sidelined.
Government Proposals to Prioritise Economic Growth
In response to these challenges, the government has announced plans to consult on new measures that would allow certain economically significant projects to bypass the lengthy queue for electricity connections. Under these proposals, AI infrastructure, electric vehicle (EV) charging hubs, and industrial sites making the transition from fossil fuels to electricity would be given preferential treatment.
AI Minister Kanishka Narayan emphasised the urgency 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 expressed strong reservations about these developments, arguing that housing projects are being overlooked in favour of energy-intensive data centres. Executive director Steve Turner stated, “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.”
Implications for Housing Supply
The preferential treatment of data centres is not a new phenomenon; they have been classified as critical national infrastructure, allowing them to bypass local objections during the planning process. This status has already led to delays in new housing developments, particularly in areas where the electricity grid is at capacity. Members of the London Assembly highlighted this issue in December, noting that several housing projects in west London had been temporarily stalled due to the limitations of the grid.
Currently, the UK is home to nearly 500 data centres, which cater to a wide range of digital services, from banking transactions to online gaming, consuming about 2% of the nation’s electricity. With the rapid expansion of AI capabilities, the demand for data centres is projected to escalate further. The National Grid estimates that electricity usage by these facilities could increase as much as six-fold by the year 2050.
Why it Matters
The intersection of energy supply and housing development could have profound implications for the UK’s future. As the government prioritises data centres in the race to harness AI’s potential, the risk of exacerbating the housing crisis looms large. Delaying new homes not only impacts families currently struggling to secure affordable housing but also threatens local economies reliant on construction and related jobs. The delicate balance between technological advancement and societal needs must be navigated with care, or the consequences could be felt for generations to come.
