The UK government’s latest proposals prioritising artificial intelligence (AI) data centres for electricity grid connections could significantly hinder new housing projects, builders have cautioned. As the demand for energy surges, particularly from data centres, the construction of homes might face considerable delays, exacerbating the ongoing housing crisis.
Surge in Electricity Demand
Recent figures reveal that approximately 140 data centres are currently vying for new electricity connections across the UK. The first half of 2025 witnessed a staggering 460% increase in the queue for these connections, largely driven by the insatiable energy appetite of AI data centres. This surge has resulted in some projects facing waiting periods extending into years before they can become operational.
The government’s proposals, unveiled on Wednesday, suggest that projects promising substantial economic growth and job creation could be given precedence in the connection queue. However, the Home Builders Federation (HBF) has issued a stark warning: neglecting to prioritise housing developments could effectively impose a moratorium on new homes.
Concerns Over Housing Prioritisation
As energy regulator Ofgem noted in November, the electricity connection queue has far exceeded even the most optimistic projections for future demand, primarily due to the influx of applications from AI data centres. Many of these applications, however, are deemed “speculative,” lacking sufficient financing, planning permissions, or land rights to transition into viable projects. The risk, according to Ofgem, is that legitimate projects further down the queue, which could generate jobs and stimulate local economies, may be sidelined.
In response, the government aims to address this predicament by considering the prioritisation of “strategically important” projects, including AI infrastructure, electric vehicle charging hubs, and industrial sites transitioning from fossil fuels to electricity.
The Builders’ Perspective
AI Minister Kanishka Narayan emphasised the importance of these reforms, stating that timely access to the grid is essential for harnessing AI’s potential to foster a more prosperous and equitable Britain. Yet, the HBF’s executive director, Steve Turner, expressed frustration over the apparent sidelining of housing projects. “As we grapple with a housing crisis, it is disheartening that regulatory and policy frameworks prioritise energy-intensive data centres over energy-efficient homes for families,” he remarked.
Turner further warned that without prioritising housing, the result would be an effective ban on new home constructions in areas where energy capacity is already strained. This sentiment has been echoed by members of the London Assembly, who noted that some housing developments in west London have already been temporarily halted due to electricity grid capacity issues.
The Growing Need for Data Centres
Currently, there are nearly 500 data centres across the UK, powering essential digital services ranging from banking to online gaming. These facilities account for around 2% of the nation’s electricity demand. As the role of AI expands, the number of data centres is expected to rise dramatically, with energy requirements projected to increase by as much as six times by 2050, according to the grid operator.
The implications of these developments are profound. While the government’s push for AI infrastructure aims to stimulate economic growth, the potential sidelining of housing projects raises urgent questions about the balance between technological advancement and essential living needs.
Why it Matters
The government’s focus on AI data centres, while economically motivated, risks compounding the UK’s housing crisis at a critical time. As energy demands grow, the prioritisation of data centres over housing could leave many families without adequate homes, further straining communities already facing housing shortages. Policymakers must navigate the delicate balance between fostering technological progress and ensuring sustainable living conditions for all citizens. The outcome of this debate will shape the future of both the economy and the fabric of society itself.
