In a move that could significantly reshape the landscape of the UK’s energy and housing sectors, new government proposals may prioritise artificial intelligence (AI) data centres for electricity grid connections, raising alarms among builders and housing advocates. The proposed changes come amid a substantial backlog of projects awaiting power supply, with implications that could effectively halt new housing developments as the demand for energy-hungry data centres surges.
Surge in Demand for Electricity Connections
The current situation is dire for many infrastructure projects across the UK. As of now, approximately 140 data centres are in line to secure new electricity connections, contributing to a staggering 460% increase in the queue during the first half of 2025. This unprecedented demand, primarily driven by the expansion of AI technologies, is forcing other critical projects, including housing, to face lengthy delays.
Under the proposed changes, projects that promise the most significant economic growth and job creation could be granted expedited access to the grid, effectively allowing them to bypass the existing queue. The government plans to consult on defining “strategically important” projects, which would include AI infrastructure, electric vehicle (EV) charging hubs, and various industrial sites transitioning away from fossil fuels.
Concerns from the Housing Sector
The Home Builders Federation (HBF) has voiced serious concerns about these developments, warning that prioritising energy-intensive data centres over new housing could create an “effective moratorium” on residential projects. Steve Turner, executive director at HBF, expressed frustration, stating, “As we continue to face a housing crisis, it is disheartening that regulatory and planning frameworks favour energy-intensive data centres over energy-efficient homes for families.”
This sentiment is echoed by local leaders. In December, members of the London Assembly’s Planning and Regeneration committee raised alarms about the reality in parts of the capital, where new housing developments have already faced delays as the electricity grid reached its capacity.
The Energy Landscape: A Double-Edged Sword
The latest figures from Ofgem, the energy sector regulator, underscore the severity of the situation. The regulator indicated that the demand for electricity connections has outstripped even the most ambitious future forecasts, largely due to the rapid growth of AI data centres. Alarmingly, many projects currently in the queue are merely speculative, lacking the necessary financing, planning permissions, or land rights to become viable.
This situation poses a dual threat: genuine projects that could stimulate local economies and create jobs are being sidelined, while speculative projects continue to monopolise essential resources. AI Minister Kanishka Narayan defended the proposed reforms, asserting that timely access to the grid is essential for harnessing AI’s potential to create a wealthier and fairer Britain.
The Future of Data Centres and Housing
Currently, nearly 500 data centres operate across the UK, powering a wide range of digital services, from banking transactions to online gaming, and these facilities already account for 2% of the nation’s electricity consumption. As AI continues to evolve, the demand for processing power is expected to escalate, with projections indicating that energy consumption by data centres may increase by up to six times by 2050.
The implications of this burgeoning demand cannot be overstated. With the current trajectory, the prioritisation of data centres could become a permanent feature of the energy landscape, sidelining essential housing projects and exacerbating the ongoing housing crisis.
Why it Matters
This unfolding situation underscores a critical crossroads for the UK: the balance between embracing technological advancement and addressing the pressing need for housing. As data centres expand to meet the demands of an increasingly digital world, the risk of sidelining vital housing projects threatens to deepen the existing crisis. It raises fundamental questions about the future of urban development, community welfare, and the sustainability of energy resources. The decisions being made today will shape the fabric of our communities for generations to come.
