Summary
- Ministers formally rejected a proposed national construction ban on 11 November.
- The response reiterates the Data Centre Covenant's expectations on energy, water, communities, and resilience.
- Individual developments remain subject to planning assessment, including the emerging national infrastructure framework.
The UK Government has rejected calls for an immediate ban on new AI data centres, maintaining that proposed facilities should be assessed individually against planning, environmental, and community requirements.
Its position was confirmed in a formal response on 11 November to a parliamentary petition seeking to prevent the construction of new AI data centres, including developments that had already received approval.
The petition cites electricity consumption, water use, industrial noise, environmental effects, and the potential consequences for the UK’s climate commitments.
Ministers have declined to introduce the requested prohibition, arguing that responsible domestic data centre growth is necessary to support digital services, public infrastructure, and future computing demand.
The response does not introduce a new development consent process or remove existing environmental obligations.
Instead, it reiterates the government’s approach through the planning system and the Data Centre Covenant, published earlier in November.
The Covenant sets expectations for how new facilities should support the electricity system, manage energy and water responsibly, invest in local communities, contribute to employment and supply chains, and strengthen national security and resilience.
These expectations are encouraged across the sector, while the most strategically important developments must meet them to qualify for additional government support.
That distinction limits the extent to which the Covenant can be treated as a universally binding statutory code.
The government also refers to its October statement on responsible energy and water use, which recognised that large concentrations of data centre development can place pressure on national infrastructure.
That statement encouraged operators to disclose information about water and electricity performance, including their ability to adjust electricity demand.
The planning system remains responsible for examining environmental effects at the level of individual proposals.
Depending on the location and application, those assessments may include noise, emissions, ecology, flood risk, water requirements, transport, and the interaction with nearby communities.
A proposed data centre may be refused if significant adverse effects cannot be appropriately managed or mitigated.
The government’s position therefore distinguishes between supporting the growth of computing infrastructure nationally and deciding whether a particular development is acceptable.
That distinction is increasingly important as projects vary considerably in scale.
Smaller facilities serving established commercial applications have different physical requirements from hyperscale campuses seeking hundreds of megawatts of electricity.
The latter can require extensive electrical infrastructure, including substations, transformers, high-voltage connections, and supporting backup systems.
Their cooling requirements also depend on the type and density of computing equipment, the selected heat-rejection method, and local environmental conditions.
The resulting electricity and water demands cannot be determined from building floorspace alone.
Nor does the status of data centres as critical national infrastructure mean that every proposed facility automatically receives permission.
Individual developments must still satisfy the relevant planning and regulatory requirements.
England is currently consulting on a draft National Policy Statement for data centres, intended to establish an assessment framework for projects proceeding through the nationally significant infrastructure regime.
That consultation closes on 8 January 2027.
The draft statement is not yet adopted policy, and the government’s petition response does not determine the outcome of the consultation.
Developers also face requirements beyond planning permission.
A site may be suitable for construction while lacking a deliverable electricity connection or the agreements necessary to support the proposed operating load.
Network reinforcement, electrical engineering, and project financing can affect whether permitted capacity progresses into operation.
The government’s refusal to impose a national ban leaves those decisions to the established combination of planning, infrastructure delivery, and commercial investment.
Opposition to the sector’s expansion remains visible through parliamentary petitions and local development disputes.
Ministers have confirmed that they intend to permit further data centre investment, but the practical conditions for individual projects will continue to be tested through planning decisions and the emerging policy framework.
