In a move that could reshape the landscape of energy distribution in the UK, the government is considering proposals to grant artificial intelligence (AI) data centres priority access to the electricity grid. This decision has raised alarms among housing developers, who warn that prioritising these power-hungry facilities could effectively halt new home construction at a time when the country is grappling with a severe housing crisis.
Surge in Demand for Electricity Connections
The UK currently has approximately 140 data centres awaiting new electricity connections, a backlog that has exploded by 460% in the first half of 2025. This surge is predominantly driven by the energy demands of data centres, which has led to prolonged waiting times for various infrastructure projects—including hospitals and housing developments. As a result, some builders face delays of several years before they can commence work.
The government’s latest proposals aim to alleviate this bottleneck by allowing projects deemed economically beneficial to bypass the queue. However, the Home Builders Federation (HBF) has expressed grave concerns that this approach prioritises data centres over much-needed housing. Steve Turner, the HBF’s executive director, stated, “It is frustrating that regulatory, planning, and policy arrangements effectively prioritise energy-intensive data centres over energy-efficient homes for families.”
Energy Sector Warnings
The urgency of the situation was underscored by Ofgem, the energy regulator, which in November warned that the backlog had surpassed even the most optimistic projections for future demand. Much of this growth is attributed to AI data centres, which are often speculative ventures lacking the necessary financing, planning permissions, or land rights to materialise into tangible projects. Consequently, legitimate housing developments further back in the queue may be sidelined, stalling local economic growth and job creation.
In response, the government is looking to consult on a new framework that would enable “strategically important” projects—such as AI infrastructure, electric vehicle charging hubs, and industrial sites transitioning from fossil fuels—to jump ahead in the line for electricity connections. AI Minister Kanishka Narayan emphasised the need for swift reforms: “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.”
Existing Challenges for Housing Developments
Despite the pressing need for new housing, data centres are currently classified as critical national infrastructure, allowing them to bypass local objections during the planning process. This preferential treatment has raised eyebrows, especially as local authorities in areas like London report that electricity grid capacity issues have already delayed new housing projects. The Planning and Regeneration committee in the capital noted that some developments in west London have faced temporary halts due to this capacity constraint.
With nearly 500 data centres already operational across the UK, they are responsible for about 2% of the country’s electricity demand. However, the growth of AI technologies threatens to escalate this figure dramatically, with projections indicating that energy usage by these centres could rise as much as six-fold by 2050.
Implications for Future Development
The tension between energy demands and housing needs underscores a critical dilemma facing policymakers. The potential prioritisation of AI data centres over residential developments could lead to an effective moratorium on new homes in regions with limited capacity. As the UK continues to struggle with a housing shortage, the challenge of balancing energy requirements with the pressing need for affordable homes remains paramount.
Why it Matters
The government’s approach to prioritising energy connections for AI data centres could have far-reaching implications for the housing market and overall economic stability in the UK. As towns and cities grapple with a lack of affordable housing, the risk of sidelining residential developments in favour of energy-intensive facilities threatens to exacerbate an already critical situation. Policymakers must navigate this complex landscape carefully to ensure that the needs of families do not fall by the wayside in the race to accommodate emerging technologies.
