Amid a surge in demand for electricity driven by the rapid expansion of artificial intelligence (AI) data centres, the UK government’s latest proposals may inadvertently hinder the construction of essential new homes. As the electricity grid faces unprecedented strain, builders warn that prioritising these energy-intensive facilities could lead to a de facto halt on housing projects, exacerbating the ongoing housing crisis.
The Current Landscape of Electricity Supply
Recent figures indicate that approximately 140 data centres are currently awaiting new electricity connections in the UK. This backlog has ballooned by an astonishing 460% in the first half of 2025 alone, largely attributed to the appetite for power from these facilities. The implications are dire: essential infrastructure projects, including hospitals and housing developments, are left languishing in a lengthy queue that now stretches for years.
In a bid to address these challenges, the government’s proposals aim to give precedence to projects promising significant economic growth and job creation. This could allow AI data centres and other strategically significant initiatives to leapfrog the queue, prompting concerns from various sectors.
Concerns from the Housing Sector
The Home Builders Federation (HBF) has expressed alarm over the potential repercussions of these proposals. According to Steve Turner, the executive director of HBF, prioritising energy-intensive data centres over housing developments could effectively impose a moratorium on new homes in regions where electricity capacity is already stretched. “As we continue to face a housing crisis, it is frustrating that regulatory, planning, and policy arrangements effectively prioritise data centres over energy-efficient homes for families,” he stated.
This sentiment is echoed by local leaders in London, where some housing projects have already been stalled due to electricity grid capacity issues. The capital’s Planning and Regeneration committee highlighted that areas in west London are experiencing delays that threaten the delivery of much-needed housing.
The Growing Demand for Data Centres
With nearly 500 data centres operating across the UK, these facilities account for approximately 2% of the nation’s electricity demand. The rise of AI is set to amplify this figure dramatically. The National Grid has projected that the electricity consumption of data centres could surge by as much as six times by 2050, as the need for advanced processing capabilities intensifies.
Given that data centres have been classified as critical national infrastructure, they enjoy certain privileges in planning processes, making it difficult for local objections to impede their development. While the government’s focus on AI and renewable energy is commendable, the potential sidelining of housing initiatives raises important questions about the balance of priorities.
Navigating a Complex Energy Landscape
The situation has prompted Ofgem, the energy regulator, to consider tightening regulations around the queue for electricity connections. The aim is to ensure that genuine projects capable of fostering local economic growth are not overshadowed by speculative developments. AI Minister Kanishka Narayan suggested that timely reforms are essential for harnessing AI’s potential to create a “wealthier and fairer Britain.” However, concerns remain about how these reforms will impact housing infrastructure.
Why it Matters
The intersection of energy demands and housing needs presents a critical dilemma for the UK. As the government seeks to embrace the future of AI and renewable energy, it must not overlook the pressing requirement for affordable and accessible housing. Failing to address this balance could lead to severe long-term consequences, further entrenching the housing crisis and disenfranchising communities across the country. As we move forward, it is imperative that policymakers consider the holistic implications of prioritising one sector over another, ensuring that all citizens have access to the homes they need while also supporting technological advancement.
