Westminster Unveils Sweeping Planning Reforms to Accelerate National Infrastructure

UK planning reforms introduced by the Planning and Infrastructure Act 2025 are intended by ministers to change how nationally significant infrastructure projects are taken through planning processes, and the government has published implementation materials setting out when and how particular measures may be brought into effect (Planning and Infrastructure Act 2025; Ministry of Housing, Communities and Local Government, “Landmark Planning and Infrastructure Bill becomes law”, 18 December 2025). This explainer summarises what those primary sources say the reforms do, how the new Act and related policy documents interact, and which matters the sources do not establish.

This article relies only on UK government primary sources: the government press releases and implementation materials and the Act itself. All dates, procedural descriptions and policy statements are taken from those official sources and are labelled by date and legal or policy status where the sources do so (see Sources). This article is general information, not legal, planning, property, investment, financial, tax or development advice. It is a source-limited explanatory report and does not replace professional advice for a particular matter.

Background and purpose

The government describes the Planning and Infrastructure Act 2025 and associated implementation material as changes intended to streamline the planning system for national infrastructure, to support growth and clean-energy missions, and to provide greater certainty and speed for applicants in the Development Consent Order (DCO) process (Ministry of Housing, Communities and Local Government, “Streamlining infrastructure planning: implementation plan”, 23 March 2026). These intentions and estimates are stated by ministers in government publications; where the sources set out numerical aims or savings these are described in those documents as government targets, estimates or stated progress, not as independently verified outcomes (Ministry of Housing, Communities and Local Government, 18 December 2025; 2 July 2026; 23 March 2026).

The material examined for this article comprises the Act itself (Planning and Infrastructure Act 2025, 2025 c. 34), the government’s announcement of Royal Assent (18 December 2025), the implementation plan (23 March 2026), a working paper published earlier in the reform process (Planning Reform Working Paper: Streamlining Infrastructure Planning, updated 13 February 2025), and a July 2026 government release describing measures brought forward (2 July 2026). This explainer sticks to the content, dates and legal or policy status stated in those materials.

What became law: Royal Assent and the Act

The Planning and Infrastructure Act 2025 received Royal Assent on 18 December 2025; the government issued a press release on that date announcing the Bill had become law (Ministry of Housing, Communities and Local Government, “Landmark Planning and Infrastructure Bill becomes law”, 18 December 2025). The Act is published as chapter 34 of the year 2025 on the official legislation site and carries a long title that describes its main subject matter (Planning and Infrastructure Act 2025, 2025 c. 34).

The government press release and the legislation record the formal enactment event: Royal Assent marks the completion of the parliamentary legislative process by which the Bill became an Act (Ministry of Housing, Communities and Local Government, 18 December 2025; Planning and Infrastructure Act 2025). As the government release itself notes, some powers were brought into force on that date while ministers indicated the timing for remaining reforms would be set out in later weeks and months (Ministry of Housing, Communities and Local Government, 18 December 2025). The Act’s official publication page similarly indicates that some provisions may be commenced at a future date (Planning and Infrastructure Act 2025).

Long title and stated scope of the Act

The Planning and Infrastructure Act 2025’s long title, as published on the legislation site, sets out the broad legal topics the Act covers: infrastructure, town and country planning, a levy to be administered by Natural England for nature restoration, development corporations, compulsory acquisition of land, environmental outcomes reports and connected purposes (Planning and Infrastructure Act 2025). Those descriptions constitute the Act’s stated scope as recorded in official legislation.

The government press release of 18 December 2025 summarises a range of measures it said the Act includes: a Nature Restoration Fund, changes to legal challenge procedures for cases a court considers totally without merit, modernising planning committees, powers for development corporations, easier acquisition of land for specified public uses, reservoir-related measures, electricity transmission community-benefit powers and grid-connection prioritisation (Ministry of Housing, Communities and Local Government, 18 December 2025). These summaries echo the Act’s long title and provisions as described in official material; the government release frames those elements in policy terms.

UK planning reforms: enactment versus commencement

Royal Assent (enactment) and commencement (bringing provisions into force) are distinct legal steps. The Act’s Royal Assent on 18 December 2025 enacted the legislation (Ministry of Housing, Communities and Local Government, 18 December 2025; Planning and Infrastructure Act 2025). However, the official legislation page and the government announcement both make clear that enactment does not automatically make every provision of the Act operative; some provisions require separate commencement actions and the timing of those is a matter for ministers and secondary legislation or commencement orders (Planning and Infrastructure Act 2025; Ministry of Housing, Communities and Local Government, 18 December 2025).

The government press release explicitly stated that some powers came into force on 18 December 2025 and that ministers would set out when remaining reforms would come into effect in later weeks and months (Ministry of Housing, Communities and Local Government, 18 December 2025). The legislation’s official page also notes that some changes may be brought into force at a future date (Planning and Infrastructure Act 2025). Therefore, enactment (the Act becoming law) is separate from commencement (individual provisions being brought into force), and both are separate from the government’s administrative steps to implement measures in practice.

Commencement: some powers in force, others later

The primary public sources make two points about commencement: first, that Royal Assent was given on 18 December 2025 (enactment) (Ministry of Housing, Communities and Local Government, 18 December 2025; Planning and Infrastructure Act 2025); second, that some powers within the Act were brought into force on that date and that the timing for commencement of remaining provisions would be announced subsequently (Ministry of Housing, Communities and Local Government, 18 December 2025). The legislation page likewise notes that provisions may be brought into force on different dates (Planning and Infrastructure Act 2025).

Where the government has given specific commencement dates in subsequent releases, those dates are quoted in those government releases and implementation documents; for example, the government stated that the statutory pre-application consultation requirement for Nationally Significant Infrastructure Projects would be removed with effect from 24 July (Ministry of Housing, Communities and Local Government, “Fastest infrastructure building in a generation as planning rules overhauled”, 2 July 2026). That statement comes from a government press release and identifies a particular commencement date for a specific reform as stated by ministers.

Secondary legislation, guidance and implementation: separate steps

The Act provides the statutory framework. Secondary legislation (regulations, commencement orders and other statutory instruments) and policy or procedural guidance are separate instruments the government may publish to implement Act provisions and explain how the provisions will operate in practice (Planning and Infrastructure Act 2025; Ministry of Housing, Communities and Local Government, “Streamlining infrastructure planning: implementation plan”, 23 March 2026).

The government’s implementation plan (23 March 2026) sets out the intended timeline for implementing measures in the Act, and how secondary legislation and guidance flowing from the Act are intended to support growth and clean-energy missions, improve and streamline the Development Consent Order process, provide greater certainty for applicants and speed delivery of national infrastructure projects (Ministry of Housing, Communities and Local Government, 23 March 2026). The plan and the Act are therefore distinct: the Act is the primary legislation; secondary legislation and guidance are instruments and documents the government says it will use to operationalise the Act’s provisions.

UK planning reforms and government implementation planning (23 March 2026)

On 23 March 2026 the Ministry of Housing, Communities and Local Government published an implementation plan titled “Streamlining infrastructure planning: implementation plan” which, according to the government, sets out target implementation timelines for measures in the Planning and Infrastructure Act 2025 and explains how the government intended to implement policies and how applicants and others could use measures once in place (Ministry of Housing, Communities and Local Government, 23 March 2026). The implementation plan frames its proposals as intended policies and timelines rather than as statements that every provision had already been commenced.

The implementation plan describes a series of actions involving secondary legislation and guidance to support the government’s stated objectives to improve the DCO process and to provide greater certainty for applicants (Ministry of Housing, Communities and Local Government, 23 March 2026). The plan therefore represents an administrative and policy roadmap from ministers; the plan itself does not by itself change the law—the Act and any commencement orders or statutory instruments do—but it sets out how the government proposes to make changes operational.

How the government describes streamlining the NSIP regime

Across the working paper (13 February 2025), the implementation plan (23 March 2026) and the July 2026 press release (2 July 2026), the government frames a consistent objective: to make the Nationally Significant Infrastructure Project (NSIP) regime faster, more certain and less costly to navigate for applicants and to focus examination resources on key issues (Planning Reform Working Paper: Streamlining Infrastructure Planning, updated 13 February 2025; Ministry of Housing, Communities and Local Government, 23 March 2026; Ministry of Housing, Communities and Local Government, 2 July 2026).

The working paper published on 13 February 2025 discussed objectives and sought views on options for a faster, more certain and less costly NSIP regime; it was a consultation-style document and not a statement that the working-paper proposals had all been adopted (Planning Reform Working Paper: Streamlining Infrastructure Planning, updated 13 February 2025). The implementation plan explains how measures flowing from the Act are intended to support the government’s growth and clean energy missions by improving and streamlining the DCO process (Ministry of Housing, Communities and Local Government, 23 March 2026). The July 2026 government release described specific operational steps the government was taking, such as removing a statutory pre-application consultation requirement, introducing earlier Planning Inspectorate technical support and streamlining examinations to focus on key issues (Ministry of Housing, Communities and Local Government, 2 July 2026).

These statements are government descriptions of intent and operational design and are presented in official documents as policy objectives or planned changes. Where the government gives numerical estimates of time savings or cost savings the sources explicitly frame them as government estimates (see sections below).

UK planning reforms and NSIPs explained from these sources

The term Nationally Significant Infrastructure Projects (NSIPs) appears across the working paper, the implementation plan and the July 2026 release. From the sources used here, NSIPs are the set of projects for which the Development Consent Order (DCO) regime applies and for which the government is proposing and implementing streamlining measures (Planning Reform Working Paper, 13 February 2025; Ministry of Housing, Communities and Local Government, 23 March 2026; 2 July 2026).

The working paper describes objectives for the NSIP regime, including reviewing National Policy Statements more regularly, enabling proportionate amendment processes, adapting consultation approaches, and supporting post-consent flexibility and statutory guidance (Planning Reform Working Paper, 13 February 2025). The implementation plan frames the DCO process as the statutory regime the government intends to improve through secondary legislation and guidance (Ministry of Housing, Communities and Local Government, 23 March 2026). The July 2026 release sets out specific changes to how NSIPs will be handled in the pre-application period and examination stage (Ministry of Housing, Communities and Local Government, 2 July 2026).

The sources do not provide a comprehensive description of the universe of projects that fall into an NSIP category beyond using the term as they apply it to the DCO regime. The working paper and implementation plan discuss the regime’s processes and policy framework; details of specific project eligibility remain matters for the statutory regime in place and for case-by-case determinations under existing law.

National Policy Statements and their role

National Policy Statements (NPSs) are cited in the working paper as documents that set the needs case, policy approach, assessment principles and generic impacts for categories of national infrastructure and form a primary framework for many NSIP decisions (Planning Reform Working Paper: Streamlining Infrastructure Planning, updated 13 February 2025). The working paper discusses more regular NPS reviews, the potential for proportionate amendment processes and the role of statutory guidance within the NSIP framework (Planning Reform Working Paper, 13 February 2025).

The implementation plan reiterates the centrality of NPSs to the DCO decision-making framework and indicates that secondary legislation and guidance flowing from the Act will seek to support the government’s policy goals in that context (Ministry of Housing, Communities and Local Government, 23 March 2026). These are the positions found in the official working paper and implementation plan.

UK planning reforms: the pre-application period and consultation

The sources describe the pre-application period and consultation as distinct parts of the DCO process where applicants engage with statutory consultees, the public and other stakeholders ahead of making a Development Consent Order application. The working paper set out questions and options for reforming pre-application consultation and related parts of the NSIP regime (Planning Reform Working Paper, 13 February 2025). The implementation plan explains that secondary legislation and guidance would support applicants once measures were in place (Ministry of Housing, Communities and Local Government, 23 March 2026).

The government’s 2 July 2026 release stated that reforms delivered through the Act would remove mandatory pre-application consultation requirements for NSIPs and said the statutory pre-application consultation requirement would be removed with effect from 24 July (Ministry of Housing, Communities and Local Government, 2 July 2026). That statement appears in the government release; the materials frame the change as a removal of a statutory requirement and the government also said it would publish new guidance and described local-authority capacity support (Ministry of Housing, Communities and Local Government, 2 July 2026). The implementation plan and working paper discussed consultation and potential changes as matters for policy and secondary instruments (Planning Reform Working Paper, 13 February 2025; Ministry of Housing, Communities and Local Government, 23 March 2026).

The sources do not, in the documents used here, quantify or detail how individual pre-application interactions between applicants and specific consultees would change in every case; they present the statutory change and associated guidance intentions.

Removal of a statutory pre-application consultation requirement

The government release dated 2 July 2026 stated that the removal of the statutory pre-application consultation requirement for NSIPs would take effect on 24 July (Ministry of Housing, Communities and Local Government, 2 July 2026). The same release said ministers intended to publish new guidance and to provide local-authority capacity support (Ministry of Housing, Communities and Local Government, 2 July 2026).

This is a statement by the government and a dated commencement claim for that specific reform contained in the government’s public material. The implementation plan and working paper discussed pre-application consultation as a topic for reform; the July 2026 release provides a dated operational change the government said it would enact (Planning Reform Working Paper, 13 February 2025; Ministry of Housing, Communities and Local Government, 23 March 2026; Ministry of Housing, Communities and Local Government, 2 July 2026).

UK planning reforms: Planning Inspectorate support and targeted examinations

The July 2026 government release described two further operational measures it said were being introduced: earlier Planning Inspectorate technical support and streamlining examinations to focus on key issues (Ministry of Housing, Communities and Local Government, 2 July 2026). The implementation plan similarly set out the government’s intent that secondary legislation and guidance would support a streamlined DCO process (Ministry of Housing, Communities and Local Government, 23 March 2026). The working paper had discussed approaches to consultation, proportionate amendments and examinations as aspects of reform (Planning Reform Working Paper, 13 February 2025).

These government materials present the Planning Inspectorate technical support and targeted examinations as aspects of the government’s operational design for the NSIP regime. They describe intended changes to support earlier engagement and to focus examinations on what the government labels the key issues for decisions.

Applications, examinations, recommendations and decisions: defined steps

The government sources use a sequence of terms in explaining the NSIP/DCO process: an application (a Development Consent Order application), an examination (the process conducted by the Planning Inspectorate), a recommendation (the Inspectorate’s conclusion and report to the decision-maker) and a decision (made by the relevant Secretary of State or decision-making authority) (Planning Reform Working Paper, 13 February 2025; Ministry of Housing, Communities and Local Government, 23 March 2026).

The working paper and implementation plan describe reform options and operational changes affecting different steps of the DCO lifecycle. The July 2026 release describes reforms affecting the pre-application period and the examination phase, and their expected interaction with Inspectorate support (Planning Reform Working Paper, 13 February 2025; Ministry of Housing, Communities and Local Government, 23 March 2026; 2 July 2026).

The sources treat application, examination, recommendation and decision as discrete steps in the statutory process. The government documents use those terms in describing intended or enacted changes to the statutory and procedural framework for NSIPs. The material does not convert an Inspectorate recommendation into a decision; it presents recommendation and decision as distinct steps in the statutory process.

Data centres and the NSIP opt-in statements

The July 2026 government release notes that data centres can opt into the NSIP regime if granted the relevant directions (Ministry of Housing, Communities and Local Government, 2 July 2026). The release said that “data centres can opt into the NSIP regime if granted” and noted three directions; it did not state that particular projects had been approved or would be approved as a consequence (Ministry of Housing, Communities and Local Government, 2 July 2026).

This is a government statement about an opt-in mechanism and referenced directions; it should be read as a description of policy design rather than as an outcome for any individual project. The working paper and implementation plan discuss the NSIP regime and possible amendments to its scope and processes; the July 2026 release mentions data centres in that operational context (Planning Reform Working Paper, 13 February 2025; Ministry of Housing, Communities and Local Government, 23 March 2026; 2 July 2026).

The government release summarising Royal Assent on 18 December 2025 listed “powers for development corporations” among the Act’s measures (Ministry of Housing, Communities and Local Government, 18 December 2025). The Act’s long title includes development corporations among its subject matters (Planning and Infrastructure Act 2025). The government materials therefore identify development corporation powers as one strand of reforms contained in or enabled by the Act.

The implementation plan links the Act and its provisions to planned secondary legislation and guidance that would operationalise the statutory powers the Act confers (Ministry of Housing, Communities and Local Government, 23 March 2026). The working paper, as earlier-stage material, explored various procedural and systemic reforms but did not itself create statutory powers (Planning Reform Working Paper, 13 February 2025).

Compulsory acquisition and land powers described in the Act

The government’s 18 December 2025 release described “easier acquisition of land for specified public uses” as among the measures in the Act and the Act’s long title references compulsory acquisition of land (Ministry of Housing, Communities and Local Government, 18 December 2025; Planning and Infrastructure Act 2025). The Act therefore addresses compulsory acquisition subjects; the government frame this as one suite of the Act’s measures.

As with other topics, the Act provides the legal framework and the implementation plan explains how secondary legislation and guidance are intended to put aspects of the Act into practice (Planning and Infrastructure Act 2025; Ministry of Housing, Communities and Local Government, 23 March 2026).

Nature Restoration Fund and levy referenced by the Act

The Planning and Infrastructure Act 2025’s long title references “a Natural England-administered nature restoration levy” and the government’s 18 December 2025 press release summarises a Nature Restoration Fund among the Act’s measures (Planning and Infrastructure Act 2025; Ministry of Housing, Communities and Local Government, 18 December 2025). These are statutory and policy elements the Act and government release identify as part of the overall legislative package.

The implementation plan situates environmental outcomes and associated processes within the scope of the Act and the government’s intended implementation steps; again, the Act is the enabling statute and the plan is the government’s roadmap for how measures will be implemented administratively (Planning and Infrastructure Act 2025; Ministry of Housing, Communities and Local Government, 23 March 2026).

Reservoir and electricity transmission measures set out in sources

The government press release of 18 December 2025 listed reservoir-related measures and electricity transmission community-benefit powers and grid-connection prioritisation among the Act’s components (Ministry of Housing, Communities and Local Government, 18 December 2025). These summaries are official descriptions of the Act’s content as presented by ministers at Royal Assent.

The implementation plan and working paper discuss electricity transmission and grid-connection prioritisation as part of infrastructure planning priorities that the government intends to address through the DCO regime and associated secondary legislation and guidance (Planning Reform Working Paper, 13 February 2025; Ministry of Housing, Communities and Local Government, 23 March 2026).

Local-authority capacity statements in official material

The July 2026 press release said the government would publish new guidance and described local-authority capacity support in the context of reforms to the NSIP regime (Ministry of Housing, Communities and Local Government, 2 July 2026). The implementation plan likewise addressed how changes would be supported administratively, including capacity considerations (Ministry of Housing, Communities and Local Government, 23 March 2026).

These statements in government material indicate that ministers consider local-authority capacity a factor in implementing the Act’s measures and that the government intends to provide support as set out in its public materials.

UK planning reforms: government targets, estimates and stated ambitions

Government releases linked to the Act include numerical aims and estimates which the government explicitly frames as targets or estimates. The 18 December 2025 release included government ambitions and estimates such as an ambition to see 1.5 million homes, an intention to decide 150 major infrastructure decisions, and a prospective resource of up to £7.5bn over a decade; the release made clear these are government ambitions and estimates rather than established outcomes (Ministry of Housing, Communities and Local Government, 18 December 2025). The 2 July 2026 release stated that the government estimated the reform could cut pre-application time by up to 12 months and save industry £1bn this Parliament and said it was on track to decide at least 150 major infrastructure projects this Parliament—these are presented by the government as estimates and stated progress (Ministry of Housing, Communities and Local Government, 2 July 2026).

The implementation plan presents target implementation timelines and describes intended policy outcomes and administrative actions to achieve them (Ministry of Housing, Communities and Local Government, 23 March 2026). Across these materials the government frames numerical figures as targets, estimates or intentions. This explainer repeats those figures only as government statements and explicitly identifies them as such.

What UK planning reforms do not establish or guarantee

The official Act text, the working paper, the implementation plan and the government press releases set out legal changes, policy intentions, administrative plans and government estimates. They do not, in these documents, establish that any particular project will obtain planning permission, be constructed, be funded, be profitable, be cheaper or faster in practice, or secure a particular decision outcome. The government materials also do not convert Inspectorate recommendations into decisions; they describe statutory processes and the intended administrative design of those processes (Planning and Infrastructure Act 2025; Planning Reform Working Paper, 13 February 2025; Ministry of Housing, Communities and Local Government, 23 March 2026; 2 July 2026; 18 December 2025).

Where the government states numerical estimates or targets (for example, time and cost savings, numbers of homes, decisions or sums of money) those figures are presented by ministers as government targets, estimates or stated progress and are not recorded by these official documents as guaranteed outcomes (Ministry of Housing, Communities and Local Government, 18 December 2025; 2 July 2026; 23 March 2026).

Legal challenges and changes to judicial review for “totally without merit” cases

The government’s Royal Assent release stated the Act included changes to attempts at legal challenges for cases a court deems “totally without merit” (Ministry of Housing, Communities and Local Government, 18 December 2025). This is the government’s description of a procedural change contained within the Act. The Act itself and the government release present the change as an element of the legislative package; any practical effect in particular cases would be a matter for courts and later statutory practice, not established by the release alone (Planning and Infrastructure Act 2025; Ministry of Housing, Communities and Local Government, 18 December 2025).

Frequently asked questions (short)

Q: What is the Planning and Infrastructure Act 2025?
A: It is primary legislation enacted by Royal Assent on 18 December 2025 that, according to its long title, covers infrastructure, town and country planning, a nature restoration levy administered by Natural England, development corporations, compulsory acquisition of land, environmental outcomes reports and connected purposes (Planning and Infrastructure Act 2025; Ministry of Housing, Communities and Local Government, 18 Dec 2025).

Q: Are all parts of the Act already in force?
A: The government stated that some powers came into force on 18 December 2025 and that ministers would set out when remaining reforms would come into effect in later weeks and months; the legislation’s official page also indicates some provisions may be brought into force later (Ministry of Housing, Communities and Local Government, 18 Dec 2025; Planning and Infrastructure Act 2025).

Q: What is an NSIP and how do these reforms affect it?
A: An NSIP (Nationally Significant Infrastructure Project) is the set of projects for which the Development Consent Order regime applies. The working paper, implementation plan and government releases describe reforms intended to make the NSIP regime faster and more certain, including removing a statutory pre-application consultation requirement for NSIPs (Planning Reform Working Paper, 13 Feb 2025; Ministry of Housing, Communities and Local Government, 23 Mar 2026; 2 Jul 2026).

Q: Will these reforms make every project faster or cheaper?
A: The government provides estimates and targets—such as an estimate that removing the statutory pre-application consultation requirement could cut pre-application time by up to 12 months and save industry £1bn this Parliament—but these are government estimates and not guarantees; practical effects will depend on implementation and case-by-case factors (Ministry of Housing, Communities and Local Government, 2 Jul 2026).

Q: Are data centres automatically NSIPs now?
A: The government release notes that data centres can opt into the NSIP regime if granted the relevant directions; that statement describes an opt-in mechanism and does not establish outcomes for any particular project (Ministry of Housing, Communities and Local Government, 2 Jul 2026).

Primary-source timeline (dated)

13 February 2025 (updated): Planning Reform Working Paper: Streamlining Infrastructure Planning — a government working paper seeking views that discussed objectives for a faster, more certain, less costly NSIP regime and considered more regular National Policy Statement reviews, proportionate amendment processes, consultation, post-consent adjustment and statutory guidance. The working paper was a consultative policy document and not a statement that its proposals had been adopted (Planning Reform Working Paper, 13 Feb 2025).
18 December 2025: Royal Assent given to the Planning and Infrastructure Bill; the government published a press release stating the Bill had become law and that some powers came into force on that date while ministers would set out when remaining reforms would come into effect in later weeks and months. The release summarised measures including a Nature Restoration Fund, changes to legal challenges for cases a court deems totally without merit, modernising planning committees, development corporation powers, easier land acquisition for specified public uses, reservoir-related measures, electricity transmission community-benefit powers and grid-connection prioritisation; it also included government ambitions and estimates such as an ambition for 1.5 million homes and up to £7.5bn over a decade—labelled by the government as ambitions or estimates (Ministry of Housing, Communities and Local Government, 18 Dec 2025; Planning and Infrastructure Act 2025).
23 March 2026: The Ministry of Housing, Communities and Local Government published “Streamlining infrastructure planning: implementation plan,” setting out the government’s target implementation timeline for measures in the Planning and Infrastructure Act 2025, and explaining how secondary legislation and guidance flowing from the Act are intended to support government growth and clean energy missions by improving and streamlining the DCO process and providing greater certainty for applicants (Ministry of Housing, Communities and Local Government, 23 Mar 2026).
2 July 2026: Government press release titled “Fastest infrastructure building in a generation as planning rules overhauled,” which stated that reforms delivered through the Act would remove mandatory pre-application consultation requirements for NSIPs, introduce earlier Planning Inspectorate technical support and streamline examinations to focus on key issues. The release stated the statutory pre-application consultation requirement would be removed with effect from 24 July and said the government would publish new guidance and provide local-authority capacity support. The release also gave government estimates about time and cost savings and restated the on-track objective to decide at least 150 major infrastructure projects this Parliament, framing those as government estimates or stated progress (Ministry of Housing, Communities and Local Government, 2 Jul 2026).
