The UK government is considering a significant shift in energy allocation policy, which could prioritise artificial intelligence (AI) data centres for electricity grid access. This move, while aimed at addressing the soaring energy demands from these centres, has raised alarms among builders who warn it could severely hinder the construction of new homes across the country.
Surge in Demand for Electricity Connections
As of the first half of 2025, the queue for new electricity connections has escalated by an astonishing 460%, predominantly due to the burgeoning demand from AI data centres. The current system requires all new infrastructure projects, from hospitals to industrial facilities, to navigate a virtual queue for access to power. The rapid growth in this queue has resulted in prolonged waiting times, with some projects facing delays of several years.
In light of this crisis, the government’s recent proposals suggest that projects promising the most economic growth and job creation could be allowed to bypass the queue, potentially relegating housing developments to a lower priority. This has prompted significant concern from the Home Builders Federation (HBF), which argues that such a policy would effectively create a moratorium on new homes.
The Conflict Between Data Centres and Housing
The HBF has voiced strong objections to the prioritisation of energy-intensive data centres over housing developments in a time of escalating housing shortages. Steve Turner, executive director at HBF, 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.”
The current planning policies already favour data centres, which are classified as critical national infrastructure. This designation allows them to bypass local objections—something that further complicates the situation for housing projects reliant on electricity connections. In December, members of the London Assembly highlighted that certain housing developments in west London had been stalled due to the electricity grid reaching its capacity.
The Future of Data Centres in the UK
The number of data centres across the UK has surged to nearly 500, fulfilling essential roles in facilitating digital services ranging from banking to online gaming. Presently, these data centres account for around 2% of the nation’s electricity consumption. With the rapid expansion of AI technology, the demand for data processing capabilities is expected to increase exponentially, potentially leading to a sixfold rise in electricity needs by 2050, as indicated by the grid operator.
To tackle the ongoing challenges, both the government and Ofgem are contemplating reforms. The government aims to expedite the development of projects deemed “strategically important,” including AI infrastructures, electric vehicle (EV) charging stations, and industrial sites transitioning from fossil fuels to electricity. However, it remains to be seen how these initiatives will balance the urgent need for housing with the demands of a growing digital economy.
Why it Matters
The tension between the need for advanced digital infrastructure and the urgent requirement for new housing highlights a critical juncture for the UK. As the country grapples with a housing crisis, prioritising energy connections for data centres at the expense of residential developments could exacerbate the situation, leading to further delays in housing availability. This dilemma underscores the need for a more nuanced approach to energy policy—one that accommodates the evolving landscape of technology while ensuring that the fundamental human need for housing is not sidelined.
