The British construction sector is sounding the alarm as proposed government reforms may prioritise artificial intelligence (AI) data centres over much-needed housing developments. With the UK grappling with a severe housing crisis, the Home Builders Federation (HBF) warns that these changes could lead to an effective halt on new homes, creating further strain on the already stretched housing market.
The Surge in Demand for Electricity
The power demands of burgeoning AI data centres have led to a dramatic backlog in the queue for new electricity connections across the UK. Recent figures indicate a staggering 460% increase in this queue during the first half of 2025, primarily fuelled by the energy needs of these data-intensive operations. Currently, all new infrastructure projects, ranging from hospitals to industrial estates, must navigate this lengthy queue, leaving some developers waiting for years to gain access to essential electricity supplies.
Concerns have been raised by various stakeholders, including politicians, about the sustainability of this growth. In November, Ofgem, the energy regulator, revealed that the electricity supply queue had exceeded even the most optimistic projections for future demand. The regulator highlighted that many projects in the queue are speculative, lacking the necessary financing or planning permissions to proceed. This raises a crucial issue: genuine projects capable of delivering economic growth and job creation are being sidelined.
Government Proposals for Change
In response to these mounting issues, the government has proposed a new framework that would allow projects deemed “strategically important” to bypass the queue for electricity connections. AI infrastructure, electric vehicle (EV) charging stations, and industrial sites transitioning away from fossil fuels are among the categories that could benefit from this expedited access.
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.” However, the HBF has expressed frustration that housing developments have not been included in this priority list, a glaring omission in light of the ongoing housing crisis.
Steve Turner, executive director of the HBF, articulated the federation’s concerns: “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 implications of this prioritisation could be dire for homebuilders and prospective homeowners alike.
Implications for Housing Developments
The preferential treatment afforded to data centres as critical national infrastructure means they can circumvent local objections, complicating the landscape for new housing projects. Turner cautioned that failing to prioritise housing could create an “effective moratorium on new homes in areas where capacity is constrained.” This scenario is already unfolding in parts of London, where the Planning and Regeneration committee reported that some housing developments in west London faced delays due to grid capacity issues.
The UK currently hosts nearly 500 data centres, which account for approximately 2% of the nation’s electricity demand. As the demand for AI services continues to escalate, the grid operator warns that electricity consumption from these data centres could increase six-fold by 2050. This burgeoning demand raises significant concerns about the sustainability of the grid and the long-term implications for housing availability.
Why it Matters
The intersection of energy policy and housing development is critical at this juncture. As the government seeks to embrace the potential of AI and other emerging technologies, it must not lose sight of the pressing need for affordable housing. The current proposals risk exacerbating an already severe housing crisis, potentially leaving countless families without suitable homes while prioritising energy-intensive data centres. The decisions made today will ultimately shape the future of both the housing market and the energy landscape in the UK, underscoring the need for a balanced approach that addresses the needs of all sectors.
