Britain’s residential crisis could deepen as artificial intelligence data centres move to the front of the electricity grid queue under new government proposals, industry leaders have cautioned. Currently, an estimated 140 data centres are waiting for new power connections alongside hospitals, industrial sites and housing developments in a fast-growing backlog. The queue has increased by 460% in the first half of 2025 alone, propelled almost exclusively by power-hungry AI infrastructure requiring unprecedented amounts of electricity. The government intends to permit “strategically significant” projects—including AI facilities, EV charging hubs and industrial decarbonisation sites—to move forward in line. However, the Home Builders Federation has raised alarm that homes are not included in the priority list, warning the move could effectively place a “moratorium” on new housing construction across the country.
The Growing Queue for Power Grid Access
The power network connection queue has become a significant obstacle for Britain’s infrastructure ambitions. In the opening months of 2025 alone, the queue expanded by 460%, a surge that far exceeded even the bleakest predictions made by energy regulators. The overwhelming bulk of this growth originates with AI data centres, which require substantial quantities of electricity to power their computing operations. With an roughly 140 data centres currently seeking connections, legitimate development initiatives—from hospitals to housing developments—now face waits stretching years into the future. The situation has become so acute that Ofgem, the power industry authority, warned in November that the queue had surpassed “even the most ambitious forecasts for future demand.”
Adding to the intricacy, many projects in the queue are speculative ventures that may never materialise into actual infrastructure. Some applicants lack sufficient funding, appropriate planning consent, or even land rights to move forward with their projects, yet they still hold prime spots in the queue for connections. This generates a problematic scenario where legitimate projects with tangible economic advantages become blocked behind applications that may never come to fruition. Ofgem has identified this problem as a significant barrier to genuine economic growth and employment generation across the country. The regulator is now considering stricter rules for entering the queue to prevent speculative applications from clogging the system and delaying legitimate infrastructure projects.
- Queue expanded 460% in first half of 2025
- AI data centers fueling bulk of demand surge
- Many projects lack financing or planning permission
- Extended waiting periods hindering legitimate development initiatives
Government Aims to Fast-Track Strategic Projects
The government has unveiled a solution to untangle the electricity grid connection bottleneck by establishing a fast track for projects considered strategically important to Britain’s economic future. Under the updated system, infrastructure projects that promise substantial economic benefits and job creation could skip the long backlog and achieve faster grid connections. This approach aims to differentiate authentic, game-changing initiatives and speculative applications that clog the system without generating real benefits. AI Minister Kanishka Narayan stated that the reforms would “help us accelerate progress, to seize AI’s potential to help create a wealthier and fairer Britain,” signalling the government’s commitment to accelerating critical infrastructure deployment across the country.
The review process will establish which business areas and schemes qualify for expedited handling under the revised framework. By allowing strategically important infrastructure to skip ahead, the government seeks to drive real economic growth while concurrently partnering with Ofgem to strengthen regulations for entry into the queue. This two-pronged strategy targets both sides of the problem: speeding up worthy projects while preventing speculative applications from blocking the system in the initial stage. However, the success of this strategy will depend heavily on how authorities interpret “of strategic significance” and whether housing initiatives get comparable priority treatment.
What Constitutes Strategically Important
- AI infrastructure and data centre infrastructure for computational needs
- Electric vehicle charging stations and electric vehicle network infrastructure
- Industrial sites switching from coal and gas toward electricity
- Projects demonstrating substantial economic expansion and job creation potential
Housing Market Raises Concerns Over Shift in Direction
The Home Builders Federation has raised serious concerns that the government’s fast-track system for data centres practically marginalizes housing developments at a time when Britain faces an acute housing shortage. Steve Turner, head at HBF, warned that prioritising energy-intensive data centres over energy-efficient homes for families represents a troubling regulatory mismatch. With housing construction already hindered by planning delays and infrastructure bottlenecks, the new power supply system threatens to worsen the crisis by allowing homes to stagnate further down the queue. The federation contends that new homes should be classified as strategically important infrastructure, given their significant effect on families and communities across the country.
The concern reflects a core conflict in the government’s development strategy. While AI data centres offer economic gains and technological advancement, residential projects deliver direct community benefit by resolving homelessness, cost-of-living strain, and community job creation. Without explicit protection for residential projects in the priority system, construction companies fear the electricity grid bottleneck might create an de facto ban on residential building. This result would undermine the administration’s housing goals and increase the shortfall between availability and need that has pushed property prices to unprecedented heights. The HBF’s warning indicates the engagement process must carefully balance conflicting infrastructure demands to avoid sacrificing long-term housing security for short-term tech sector gains.
Practical Effect in London and Beyond
Across significant metropolitan areas like London and other growing regions, housing developers already face extended delays spanning years for grid connections as the queue has grown by 460% in just the first half of 2025. Without housing included in the priority system, residential projects could experience even longer delays, pushing completion dates further down the line and reducing the annual supply of new homes. This bottleneck threatens to deepen housing shortages in areas where demand is highest and affordability pressures most severe, potentially forcing developers to abandon projects or relocate to areas with improved connection availability.
Data Centre Demand Transforming Energy Infrastructure
The dramatic surge in artificial intelligence has fundamentally transformed Britain’s power grid landscape. With an estimated 140 data centres currently waiting for new power connections, the demand for power has far exceeded even the most bullish forecasts. These installations, which require vast amounts of electricity to operate the computing systems that enable AI services, have established themselves as the main catalyst of new connection requests. The upswing reflects the worldwide competition to establish AI infrastructure, with major technology companies and network operators competing to establish data centre operations across the UK to support European demand and support emerging artificial intelligence services.
Ofgem’s recent warnings highlight the severity of the infrastructure challenge confronting Britain’s energy system. The regulatory authority has raised concerns that many projects in the queue are entirely speculative, lacking proper financing, planning approval, or secured land rights despite their position in the queue. This produces a bottleneck effect where genuinely viable projects—whether residential developments, hospitals, or industrial facilities—find it difficult to advance while data centre applications that are speculative occupy queue positions. The proposed government reforms aim to address this ineffectiveness by introducing a merit-based system that gives priority to projects offering real economic growth and job generation, though the framework’s exact parameters are still being consulted on.
| Year Period | Electricity Demand Change |
|---|---|
| First half of 2025 | Queue grew by 460% |
| Recent months (pre-2025) | Surged past ambitious forecasts |
| Current status | 140 data centres awaiting connection |
| Typical project wait time | Multiple years for grid access |
Reconciling Innovation and Housing Demand
The government’s effort to prioritize AI data centres has highlighted a basic contradiction in Britain’s infrastructure approach. While government representatives maintain that data centre investment is essential for economic expansion and technological advancement, housing advocates warn that reducing focus on housing projects could have severe consequences for the nation’s chronic housing challenge. The Home Builders Federation has been notably critical, arguing that the existing policy essentially establishes a “moratorium” on new homes by relegating housing developments lower than data centres in the grid queue. This worry underscores wider concerns that energy-intensive facilities are being favored over efficient housing developments intended to provide homes and resolve Britain’s persistent housing deficit.
The planned reforms seek to establish a merit-based system where projects demonstrating the greatest economic value and employment generation potential can move forward in the queue. However, housing developments—which produce significant local employment, tax revenue, and social benefits—have not been clearly designated as key priorities. This oversight has concerned builders and housing advocates who argue that homes should be treated on par with technology hubs and manufacturing plants in terms of long-term significance. The consultation process will determine whether residential projects can be recategorized as priorities for development, fundamentally changing how Britain reconciles technological innovation with the pressing demand for low-cost housing.
