Data centres can opt into England’s NSIP planning

Data centres now have a clearer national route through planning. Regulations made on 7 January 2026, in force from 8 January 2026, add “data centres” to the list of business or commercial projects that can be brought into the Planning Act 2008 regime. In plain terms, very large or complex server farms can, on request, be examined through the Nationally Significant Infrastructure Project (NSIP) process rather than only through local planning. The change updates the 2013 Regulations and reflects commitments set out by ministers. (legislation.gov.uk)

What actually changed is simple: the Schedule to the 2013 rules now includes “Data centres” as a prescribed project type. That unlocks Section 35 of the Planning Act 2008, which allows the Secretary of State to direct that a specific proposal is of national significance and should use the NSIP process. It is not automatic. Developers apply to “opt in”, and a direction is made only if ministers judge the scheme meets the national significance test. (legislation.gov.uk)

If a data centre is directed into the NSIP route, the consent is a Development Consent Order (DCO). The steps are structured: pre-application engagement, an acceptance decision within 28 days, an examination, and then a ministerial decision. Government guidance explains typical timings and how the public can register as “interested parties” to have a say, with fast‑track options aiming for a decision in around 12 months from acceptance where standards are met.

Ministers say this shift is about supporting the UK’s digital backbone while improving certainty for applicants and communities. The written statement by Matthew Pennycook confirmed the policy and flagged that the Department for Science, Innovation and Technology will prepare a National Policy Statement (NPS) for data centres to guide decisions, including the kinds of thresholds that might indicate national significance. (questions-statements.parliament.uk)

For you as a student planner or early‑career practitioner, the practical question is when a promoter might choose NSIP. The Commons debate set out examples: proposals tied to on‑site energy generation, exceptionally large footprints, complex grid or water needs, or cases that would benefit from a single consent instead of multiple local permissions. These are the sorts of schemes likely to consider the “opt‑in” request. (hansard.parliament.uk)

Public involvement remains central. Even when a data centre uses the NSIP route, there is mandatory consultation before submission, an open registration period so people can become interested parties, and a structured examination where issues are tested in public. Local authorities still prepare a Local Impact Report setting out effects on housing, transport, environment and services in their area. (gov.uk)

A quick geography note helps. The instrument sits under “Infrastructure Planning, England” but the Regulations extend to England and Wales. In practice, the NSIP system is the consenting pathway for specified infrastructure under the 2008 Act, while devolved planning arrangements continue to apply in Wales for areas outside that framework. The legal text adding “Data centres” is in the amended Schedule itself. (legislation.gov.uk)

Most proposals will still go through normal town and country planning. The NSIP direction is there for exceptional cases, not as a blanket rule. That balance-local decision‑making for typical developments, a national process for nationally significant ones-is set out in Parliament’s debate and in the Planning Inspectorate’s own explainer. (hansard.parliament.uk)

If you’re mapping this for an assignment or workplace project, think in sequences. Start with the question of scale and complexity, then check policy fit and infrastructure needs. If NSIP looks sensible, early engagement is vital: talk to the Planning Inspectorate’s pre‑application service, build your consultation plan with local communities, and prepare for an examination that focuses on evidence. The headline for learners is this: you now have two lawful routes-local planning or, where it truly matters nationally, the NSIP process-and understanding both is part of being an informed planner.
