Data centres added to NSIP route in England and Wales

From 8 January 2026, data centres can be treated as Nationally Significant Infrastructure Projects in England and Wales. Regulations signed on 7 January 2026 by Housing Minister Matthew Pennycook allow developers to ask ministers to determine qualifying proposals through a single Development Consent Order rather than multiple local permissions, where a project is judged nationally significant. UK Parliament statements confirm this ‘opt‑in’ approach. (questions-statements.parliament.uk)

Let’s get our bearings. An NSIP is a very large scheme decided nationally under the Planning Act 2008, covering areas like energy, transport, water and waste. Instead of a standard planning application, the developer seeks a Development Consent Order (DCO) decided by a Secretary of State. This is still a rules‑based process with public input and legal safeguards. The House of Commons Library has a clear primer on how this works. (commonslibrary.parliament.uk)

How a DCO runs in practice matters for everyone who wants to have a say. The Planning Inspectorate first checks the application is complete. If it’s accepted, the examination phase can run for up to six months. Inspectors then have three months to recommend a decision, and the minister normally has another three months to decide. There is a six‑week window for legal challenge after that. (infrastructure.planninginspectorate.gov.uk)

What exactly changed in law? Ministers amended the Infrastructure Planning (Business or Commercial Projects) Regulations 2013 so the Schedule now lists one more type of project: “10. Data centres.” That single line matters because section 35 of the Planning Act lets ministers only direct projects of a prescribed description into the NSIP route. (legislation.gov.uk)

Is this automatic? No. In the Commons debate, ministers stressed that the NSIP route will be optional and used case‑by‑case. A developer can request a direction, and the Secretary of State can only agree if they believe the proposal is of national significance and the other section 35 tests are met. That safeguard is written into the law and was reiterated to MPs. (hansard.parliament.uk)

To guide consistent decisions, the Department for Science, Innovation and Technology is preparing a new National Policy Statement for data centres. Ministers told Parliament this policy will set out parameters and thresholds that indicate when a data centre may be nationally significant, and it will frame how applications are assessed. Expect a public consultation. (questions-statements.parliament.uk)

Why now? Demand for secure computing power is growing across AI, cloud services and public systems. National planning policy was also updated in December 2024 to ask councils to plan for data centres as part of meeting the needs of a modern economy. That provides local plan support alongside the new national consenting option. (commonslibrary.parliament.uk)

Will local voices still be heard? Yes. Developers must consult widely at pre‑application. Anyone can register as an “Interested Party” by making a relevant representation once an application is accepted. The Planning Inspectorate’s GOV.UK guide explains who can register, what to submit and how updates are issued. (gov.uk)

What to expect if a data centre uses the DCO route: after acceptance, the examination invites written evidence and questions over a tightly managed timetable. The Inspectorate aims for six months on examination, then three months to recommend, and a further three months for the decision. This schedule helps everyone plan their involvement. (infrastructure.planninginspectorate.gov.uk)

Which schemes might choose this route? In committee, ministers pointed to very large or complex proposals, projects with on‑site power generation, or cases that would benefit from a single consent instead of numerous separate permissions. That gives developers and councils a clear signal about when NSIP could save time and uncertainty. (hansard.parliament.uk)

A quick teaching point. This change arrived through secondary legislation rather than a new Act. It’s a good example to use in class: Parliament debated and approved the draft instrument, ministers then made it, and it took effect the next day. The Parliamentary record shows it was laid on 15 October 2025, debated in November, and approved by both Houses before being made in early January 2026. (statutoryinstruments.parliament.uk)

Another note from the official explanatory text: ministers can only direct a project into the NSIP system if they think it is of national significance, and no full impact assessment was produced for this instrument because no significant impact on the private or voluntary sectors was expected. That context is published alongside the instrument. (legislation.gov.uk)

What this means for you. If you’re studying planning or teaching civic participation, this is a ready‑made case study. You can track any data centre NSIP on the Planning Inspectorate’s site, sign up for updates, and practise drafting a clear, evidence‑based relevant representation when a consultation window opens.

What to watch next. Look out for DSIT’s draft National Policy Statement for data centres and the first section 35 directions that test the new route. Together they will show how “national significance” is interpreted and which issues-such as grid capacity, siting and community benefits-carry the most weight. (questions-statements.parliament.uk)
