The UK government’s latest proposals to prioritise artificial intelligence (AI) data centres for electricity connections could severely hinder the construction of new homes, according to industry experts. As demand for energy surges, the Home Builders Federation (HBF) has raised alarms that this move may effectively place a moratorium on housing projects in areas where electricity capacity is already strained.
Energy Demands Surge
Recent statistics reveal that there are approximately 140 data centres in the UK seeking new electricity connections. The first half of 2025 witnessed an astonishing 460% increase in this queue, primarily fuelled by the insatiable energy appetite of data centres. These facilities, deemed critical national infrastructure, have been granted preferential access to the electricity grid, forcing other essential projects—such as housing developments—to languish in a lengthy waiting list.
Ofgem, the energy regulator, has expressed concern that the current queue has surpassed even the most optimistic projections for future demand. Many prospective projects are deemed “speculative,” lacking the necessary financing, planning permissions, or land rights to materialise. As a result, genuine initiatives that could stimulate job creation and local economic development risk being sidelined.
Government’s Proposal
On Wednesday, the government announced plans to facilitate faster electricity access for projects deemed economically vital, including AI infrastructure and electric vehicle charging hubs. The proposal aims to allow strategically important projects to bypass the existing queue, thereby expediting their connection to the grid. AI Minister Kanishka Narayan emphasised that these reforms are essential to harness the potential of AI for building a more prosperous and equitable Britain.
However, the Home Builders Federation has expressed frustration over the exclusion of housing developments from this priority list. Steve Turner, executive director of the HBF, described the current situation as deeply troubling, especially amidst an ongoing housing crisis. He pointed out that prioritising energy-hungry data centres over energy-efficient homes for families is a misguided approach that could exacerbate the housing shortage.
The Reality on the Ground
The implications of these proposals are already being felt in various parts of the UK. Members of the London Assembly reported in December that several housing developments in west London had been delayed due to the electricity grid reaching capacity. The Planning and Regeneration committee noted that this situation is becoming increasingly common, with areas facing significant obstacles in advancing vital housing projects.
Currently, there are nearly 500 data centres operating throughout the UK, contributing to 2% of the nation’s electricity demand. As the growth of AI continues, the energy requirements for these facilities are projected to multiply six-fold by 2050, creating further strain on the already burdened electricity grid.
Why it Matters
The government’s decision to prioritise AI data centres could have far-reaching consequences for the housing market and the overall economy. With an acute housing crisis already in play, sidelining residential developments in favour of energy-intensive data centres may not only delay the construction of much-needed homes but could also stifle economic growth in local communities. As the demand for electricity continues to climb, it becomes crucial to strike a balance that addresses both technological advancements and the urgent need for housing. In making these decisions, policymakers must consider the long-term implications for families and communities across the UK.
