Amid rising energy demands, proposed government reforms may prioritise artificial intelligence (AI) data centres over much-needed housing developments, sparking concerns from builders and housing advocates. With the UK’s electricity grid already strained, the potential for a prioritised connection system could effectively halt new home construction, exacerbating the ongoing housing crisis.
A Surging Demand for Power
Currently, there are approximately 140 data centres awaiting new electricity connections in the UK, and the situation is becoming increasingly dire. The first half of 2025 witnessed a staggering 460% increase in the queue for electricity supply, largely driven by the insatiable appetite of data centres. This surge has resulted in some projects facing multi-year delays before they can even begin operations.
Under new government proposals, projects deemed to promise substantial economic growth and job creation could leap ahead in the connection queue. However, this prioritisation raises alarm bells for the Home Builders Federation (HBF), which warns that sidelining housing developments would create an effective “moratorium” on new homes.
Prioritising Economic Growth Over Housing
In November, Ofgem, the UK’s energy regulator, issued a stark warning about the current electricity connection queue, stating it had surpassed even the most optimistic demand forecasts. The regulator highlighted that many of the projects in line were merely speculative. Even if granted a connection, these projects often lack essential financing, planning permissions, or land rights to become viable initiatives.
The government’s strategy aims to alleviate this issue by fast-tracking projects that offer the most significant potential for economic development and job creation. Among these “strategically important” projects are AI infrastructure, electric vehicle (EV) charging hubs, and industrial sites transitioning from fossil fuels to electricity. Nevertheless, the absence of housing developments from this priority list has drawn heavy criticism.
AI Minister Kanishka Narayan stated, “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.” Yet, the HBF’s executive director, Steve Turner, argues that the focus on energy-intensive data centres is misguided given the urgent need for energy-efficient homes.
The Consequences for Housing Development
The HBF has expressed frustration over the regulatory and planning frameworks that appear to favour data centres over housing. Turner cautioned that without prioritising housing projects, the situation could lead to a significant slowdown in new home construction, particularly in areas facing capacity constraints.
In December, members of the London Assembly noted that certain housing developments in west London had been delayed due to the electricity grid reaching its limit. This situation illustrates the real-world implications of prioritising data centres at the expense of residential projects. With nearly 500 data centres already operational across the UK, providing essential digital services—from banking to online gaming—these facilities account for roughly 2% of the nation’s electricity demand.
As the AI sector continues to expand, the electricity requirements of data centres could swell by as much as six times by 2050, according to the national grid operator. This projected increase poses a formidable challenge for the UK’s energy infrastructure and its capacity to support both economic growth and housing needs.
Why it Matters
The intersection of energy demand, economic growth, and housing availability is a pivotal issue for the UK. As the government contemplates prioritising AI data centres, it must also recognise the critical need for new housing developments. Ignoring the housing crisis in favour of data centre expansion could lead to a long-lasting detrimental impact on communities, exacerbating affordability issues and making it increasingly difficult for families to secure homes. Balancing these competing demands is essential in shaping a sustainable future for the UK, one where economic progress does not come at the expense of housing security.
