New proposals from the UK government to prioritise artificial intelligence (AI) data centres for electricity connections could severely hinder the construction of new homes, builders have cautioned. As the demand for energy grows exponentially, the existing backlog for electricity connections has skyrocketed, leaving housing projects in jeopardy.
Electricity Connection Queue Swells
The number of projects awaiting electricity connections has surged, with reports indicating a staggering 460% increase in the first half of 2025 alone. This surge is primarily attributed to the insatiable energy demands of AI data centres, which are now vying for limited grid capacity alongside essential infrastructure like hospitals and schools. Currently, new projects must navigate a virtual queue to access electricity, resulting in lengthy delays—sometimes extending into years.
According to the energy regulator Ofgem, the backlog has surpassed even the most ambitious forecasts for future energy demands, raising alarms about the feasibility of many proposed projects. Some of these, designated as “speculative,” lack adequate funding, planning permission, or land rights, jeopardising their actualisation. The concern is that genuine housing and job-creating projects may be overshadowed by less viable data centre initiatives.
Government’s New Prioritisation Plans
In response to these challenges, the government is contemplating a new framework that would allow projects deemed to contribute significantly to economic growth and job creation to bypass the waiting list. This initiative includes prioritising AI infrastructure, electric vehicle (EV) charging stations, and industrial sites moving away from fossil fuels. AI Minister Kanishka Narayan asserted that these reforms are crucial for harnessing AI’s potential to foster a more prosperous and equitable Britain.
However, the Home Builders Federation (HBF) has expressed strong reservations regarding this strategy. Steve Turner, executive director at HBF, articulated his frustration over the lack of prioritisation for housing projects, particularly amidst an ongoing housing crisis. He warned that if housing developments are not regarded as critical infrastructure, it could effectively impose a moratorium on new homes in areas where electricity capacity is already stretched.
The Impact on Housing Developments
The situation is particularly dire in London, where local Assembly members have noted that some housing projects in west London have faced delays due to grid saturation. The Planning and Regeneration committee highlighted that as data centres continue to receive preferential treatment—labelled as critical national infrastructure—they can move forward despite local objections, leaving housing projects in limbo.
Currently, there are nearly 500 data centres across the UK, responsible for managing various digital services, from banking transactions to online gaming. They already consume around 2% of the nation’s electricity. With the anticipated growth in AI usage, the number of data centres is expected to multiply, pushing electricity demand potentially six-fold by 2050, according to projections from the National Grid.
A Balancing Act Between Growth and Necessity
As the government seeks to modernise its energy infrastructure, a delicate balance must be struck between fostering economic growth through technology and ensuring that essential housing developments are not sidelined. The current trajectory suggests that without immediate action to prioritise residential projects, many communities could face a prolonged housing crisis exacerbated by energy supply constraints.
Why it Matters
The intersection of energy policy and housing development is a critical battleground for the UK. With the demand for electricity rising rapidly, especially from energy-intensive data centres, the potential sidelining of housing initiatives poses a significant threat to community stability and affordability. As the government navigates these complexities, it must recognise that sustainable growth relies not just on technological advancement but also on meeting the fundamental needs of its citizens for adequate and affordable housing. The choices made today will shape the landscape of Britain’s future, determining whether it can achieve a balance that supports both innovation and community well-being.
