Britain’s residential crisis could worsen as artificial intelligence data centres move to the front of the electricity grid queue under new government proposals, sector experts have cautioned. Currently, an estimated 140 data centres are seeking new power connections alongside hospitals, industrial sites and housing developments in a rapidly expanding backlog. The queue has increased by 460% in the first half of 2025 alone, driven almost entirely by power-hungry AI infrastructure demanding unprecedented amounts of electricity. The government intends to permit “strategically important” projects—including AI facilities, EV charging hubs and industrial decarbonisation sites—to skip ahead. However, the Home Builders Federation has raised alarm that homes are not included in the priority list, cautioning the move could effectively impose a “moratorium” on new housing construction across the country.
The Rising Waiting List for Grid Connections
The power network connection queue has become a significant obstacle for Britain’s development goals. In the opening months of 2025 alone, the queue expanded by 460%, a spike that far exceeded even the most pessimistic forecasts made by energy regulators. The overwhelming bulk of this growth stems from AI data centres, which consume enormous amounts of electricity to operate their processing activities. With an estimated 140 data centres currently waiting for connections, legitimate development initiatives—from hospitals to housing developments—now experience delays 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 complexity, many queued projects are speculative undertakings that may never develop into actual infrastructure. Some applicants lack adequate funding, appropriate planning consent, or even property rights to move forward with their projects, yet they still occupy valuable positions in the queue for connections. This creates a perverse situation where genuine projects with real economic benefits become delayed by applications that may never come to fruition. Ofgem has recognised this issue as a significant barrier to authentic economic development and job creation across the country. The regulator is now implementing tougher requirements for entering the queue to prevent speculative applications from clogging the system and delaying legitimate infrastructure projects.
- Queue grew 460% in opening six months of 2025
- AI data centers fueling bulk of demand surge
- Many projects are missing financing or planning permission
- Years-long waits blocking genuine infrastructure projects
Government Aims to Expedite Strategic Projects
The government has proposed a solution to resolve the electricity grid connection bottleneck by establishing a expedited pathway for projects considered strategically important to Britain’s economic growth. Under the updated system, infrastructure projects that offer considerable job creation and job creation could circumvent the lengthy queue and secure accelerated connections. This approach aims to distinguish between authentic, game-changing initiatives and speculative applications that burden the process without generating real benefits. AI Minister Kanishka Narayan stated that the reforms would “help us proceed swiftly, to seize AI’s potential to help create a wealthier and fairer Britain,” signalling the government’s commitment to fast-tracking key infrastructure projects across the country.
The review process will establish which business areas and schemes are eligible for preferential status under the new system. By enabling critical infrastructure to move forward in the queue, the government aims to unlock genuine economic development while concurrently partnering with Ofgem to tighten rules for initial queue entry. This dual approach targets both sides of the problem: speeding up worthy projects while stopping speculative submissions from clogging the process in the first place. However, the effectiveness of this approach will rely significantly on how authorities interpret “strategically important” and whether housing developments get comparable priority treatment.
What Constitutes Strategically Important
- AI infrastructure and data centre facilities for computing operations
- Electric vehicle charging hubs and EV infrastructure networks
- Industrial sites switching from fossil fuels to electricity
- Projects demonstrating substantial economic expansion and job creation potential
Real Estate Industry Issues Warning Over Change in Focus
The Home Builders Federation has raised serious concerns that the government’s expedited process for data centres effectively sidelines housing developments at a time when Britain confronts a severe 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 hampered by planning delays and infrastructure bottlenecks, the new power supply system risks exacerbating the crisis by allowing homes to stagnate further down the queue. The federation argues that new homes should be designated strategically important infrastructure, given their significant effect on families and communities across the country.
The concern demonstrates a fundamental tension in the government’s growth agenda. While AI computing facilities promise financial advantages and tech progress, housing developments deliver direct community benefit by addressing homelessness, cost-of-living strain, and community job creation. Without specific protections for residential projects in the priority structure, construction companies are concerned the electricity grid bottleneck could become an effective moratorium on residential building. This outcome would weaken the administration’s housing goals and expand the deficit between availability and need that has pushed property prices to record levels. The HBF’s caution implies the engagement process must judiciously manage competing infrastructure needs to prevent abandoning long-term housing security for immediate technology industry benefits.
Real-World Impact in London and Beyond
Across major urban centres like London and other growing regions, housing developers already face prolonged waiting periods 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 face extended hold-ups, pushing completion dates further down the line and lowering the yearly output of new homes. This capacity crunch threatens to entrench housing shortages in areas where demand is highest and affordability pressures most severe, potentially forcing developers to pull out of schemes or relocate to areas with better grid access.
Data Center Demand Reshaping Energy Infrastructure
The explosive growth in machine learning has dramatically altered Britain’s electricity infrastructure landscape. With an estimated 140 data centres currently seeking new power connections, the electricity demand has greatly outpaced even the most bullish forecasts. These operations, which need substantial quantities of electricity to run the computing infrastructure that power AI applications, have established themselves as the main catalyst of new connection requests. The spike reflects the worldwide competition to develop artificial intelligence capacity, with prominent technology providers and infrastructure providers competing to establish data centre operations across the UK to cater to European needs and facilitate cutting-edge AI solutions.
Ofgem’s latest cautions highlight the severity of the infrastructure challenge confronting Britain’s power grid. The regulatory authority has raised concerns that many projects in the queue are purely speculative, without proper financing, planning approval, or land rights secured in spite of their position in the queue. This produces a bottleneck effect where truly viable projects—whether housing developments, hospitals, or industrial operations—find it difficult to advance while speculative data centre applications occupy queue positions. The government’s proposed reforms aim to address this inefficiency by introducing a merit-based approach that prioritises projects offering real economic growth and job creation, though the exact parameters of the framework remain under consultation.
| 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 |
Balancing Innovation with Housing Needs
The government’s initiative to advance AI data centres has revealed a fundamental tension in Britain’s infrastructure planning. While officials contend that data centre investment is crucial for economic expansion and tech competitiveness, housing campaigners alert policymakers that sidelining residential construction could result in significant harm for the nation’s persistent housing shortage. The Home Builders Federation has been especially outspoken, arguing that the current approach essentially establishes a “moratorium” on new homes by relegating housing developments beneath data centers in the grid queue. This apprehension reflects wider concerns that power-hungry installations are being favored over energy-efficient residential projects designed to house families and tackle Britain’s chronic housing shortage.
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 generate substantial local employment, tax income, and social benefits—have not been clearly designated as priority infrastructure. This oversight has concerned builders and housing advocates who argue that homes should rank equally with data centres and industrial facilities in terms of strategic importance. The consultation process will determine whether residential projects can be recategorized as priorities for development, potentially reshaping how Britain balances technological innovation with the pressing demand for low-cost housing.
