Britain’s housing crisis could worsen as artificial intelligence data centres move to the front of the electricity grid queue under new government proposals, sector experts have warned. Currently, an estimated 140 data centres are waiting for 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, propelled almost exclusively by power-hungry AI infrastructure demanding unprecedented amounts of electricity. The government intends to permit “strategically significant” projects—including AI facilities, EV charging hubs and industrial decarbonisation sites—to skip ahead. However, the Home Builders Federation has sounded the 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 Backlog for Power Grid Access
The electricity grid connection queue has become a critical bottleneck for Britain’s development goals. In the first half 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 consume enormous amounts of electricity to operate their processing activities. With an roughly 140 data centres currently waiting for connections, genuine infrastructure projects—from hospitals to housing developments—now face waits stretching years into the future. The situation has become so severe that Ofgem, the energy sector regulator, 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 develop into real infrastructure. Some applicants lack sufficient funding, appropriate planning consent, or even land rights to proceed with their projects, yet they still occupy valuable positions in the queue for connections. This generates a problematic scenario where legitimate projects with tangible economic advantages become delayed by applications that may never be implemented. Ofgem has identified this problem as a major obstacle to authentic economic development and employment generation across the country. The regulator is now implementing tougher requirements for joining the queue to stop speculative proposals from overwhelming the process and holding up genuine infrastructure developments.
- Queue expanded 460% in first half of 2025
- AI data centres powering majority of demand surge
- Numerous initiatives are missing financing or planning permission
- Extended waiting periods blocking genuine infrastructure projects
Government Plans to Fast-Track Strategic Projects
The government has unveiled a solution to untangle the electricity grid connection bottleneck by creating a expedited pathway for projects considered strategically important to Britain’s economic future. Under the updated system, infrastructure projects that offer considerable job creation and job creation could bypass the extended waiting list and achieve quicker grid access. This approach aims to separate authentic, game-changing initiatives and speculative applications that burden the process without providing 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 consultation process will establish which sectors and projects are eligible for preferential status under the new system. By enabling critical infrastructure to move forward in the queue, the government hopes to facilitate authentic economic expansion while at the same time collaborating with Ofgem to strengthen regulations for initial queue entry. This combined method addresses both aspects of the issue: speeding up worthy projects while stopping speculative submissions from clogging the process in the outset. However, the effectiveness of this approach will rely significantly on how decision-makers characterize “of strategic significance” and whether housing developments obtain similar priority ranking.
What Defines Strategically Important
- AI systems and data center facilities for computing operations
- Electric vehicle charging stations and electric vehicle network infrastructure
- Industrial sites transitioning away from fossil fuels to electricity
- Projects demonstrating significant economic growth and job creation potential
Real Estate Industry Sounds Alarm Over Priority Shift
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, executive director at HBF, warned that favoring power-hungry data centres instead of efficient residential properties for families constitutes a concerning regulatory mismatch. With housing construction already hampered 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 argues that new homes should be classified as strategically important infrastructure, given their significant effect on families and communities across the country.
The issue demonstrates a basic contradiction in the government’s growth agenda. While AI data centers suggest economic gains and technological advancement, housing construction deliver instant social impact by tackling homelessness, housing affordability challenges, and community job creation. Without specific protections for home-building efforts in the priority structure, developers worry the power grid constraint could result in an effective moratorium on residential building. This outcome would compromise the administration’s housing goals and increase the shortfall between stock and requirements that has driven real estate costs to historic highs. The HBF’s alert suggests the consultation process must carefully balance conflicting infrastructure demands to prevent abandoning long-term housing security for immediate technology industry benefits.
Tangible Influence in London and Beyond
Across large cities like London and other growing regions, housing developers already face multi-year waits 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 decreasing the annual supply of new homes. This bottleneck threatens to entrench housing shortages in areas where demand is highest and affordability pressures most pronounced, potentially forcing developers to shelve developments or move to areas with better grid access.
Data Center Demand Transforming Energy Systems
The dramatic surge in artificial intelligence has substantially reshaped Britain’s power grid landscape. With an approximately 140 data centres currently waiting for new power connections, the power requirements has significantly surpassed even the most bullish forecasts. These installations, which need substantial quantities of electricity to operate the computing systems that enable AI services, have emerged as the primary force of fresh grid applications. The spike reflects the worldwide competition to develop artificial intelligence capacity, with prominent technology providers and infrastructure providers working to develop data centre operations across the UK to cater to European needs and enable new AI applications.
Ofgem’s latest cautions underscore the severity of the infrastructure hurdle facing Britain’s power grid. The regulatory authority has expressed concern that many projects in the queue are entirely speculative, without adequate funding, planning approval, or secured land rights despite their place in line. This creates a bottleneck effect where genuinely viable projects—whether residential developments, hospitals, or industrial operations—find it difficult to advance while speculative data centre applications take up places in the queue. The government’s proposed reforms seek to resolve this inefficiency by introducing a merit-based system that prioritises projects offering genuine economic growth and job creation, though the framework’s exact parameters 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 |
Striking a Balance Between Innovation and Housing Requirements
The government’s push to prioritise AI data centres has revealed a basic contradiction in Britain’s infrastructure strategy. While ministers argue that data centre investment is vital to economic development and technological advancement, housing campaigners warn that reducing focus on housing projects could result in significant harm for the nation’s persistent housing shortage. The Home Builders Federation has been particularly vocal, asserting that the present strategy essentially amounts to a “moratorium” on residential construction by relegating housing developments below data centres in the grid queue. This apprehension demonstrates general dissatisfaction that energy-demanding facilities are being favored over energy-efficient residential projects intended to provide homes and tackle Britain’s persistent housing deficit.
The planned reforms seek to establish a merit-based system where projects demonstrating the highest financial returns and job creation potential can skip ahead in the queue. However, residential projects—which generate substantial community jobs, tax revenue, and community advantages—have not been clearly designated as priority infrastructure. This omission has alarmed construction firms and housing campaigners who argue that homes should be treated on par with data centres and industrial facilities in terms of long-term significance. The review period will establish whether housing developments can be reclassified as priorities for development, potentially reshaping how Britain balances digital advancement with the urgent need for affordable homes.
