The Act’s headlines promised faster decisions and smoother delivery. But projects don’t get built on headlines. They get built when guidance, policy and day‑to‑day behaviours line up, and when promoters treat consenting, land and environment as one joined‑up delivery problem.
For infrastructure promoters, the most consequential part of the Planning & Infrastructure Act is not what received Royal Assent, it’s what happens next. Implementation is where the system’s working practices get set: what counts as “enough” consultation, what evidence is proportionate, how examinations are run, how quickly challenges are dealt with, and whether land assembly can keep pace with construction programmes. Mark Gilkes, a partner in our infrastructure land rights and consultancy team, puts it simply: this phase will decide whether the Act becomes a delivery tool, or just another layer of change to manage.
First up: NSIP reform. The DCO regime is legally robust, but it has become increasingly front‑loaded and resource‑intensive. Too many projects burn time proving process compliance, while the real risks, land, constructability, mitigation and challenge, stack up in the background.
The direction of travel is clear: removing statutory consultation requirements does not remove the need to consult. In practice, that means a shift away from rigid pre-application choreography and towards guidance-led, evidence-backed engagement. Examinations may become tighter and more focused on the issues that actually determine consent, but promoters will still need to show that they have listened, responded and built a defensible record. If anything, less prescription raises the bar on professionalism: when the rules become more flexible, teams need sharper judgement, clearer audit trails and better justification for the choices they make.
The biggest prize may still be time in pre-application, especially for linear schemes and complex energy and grid projects where design evolves. But flexibility in design is not a licence to stay vague. Projects will still need clear design fixes, clear justification for what is being taken forward, and a robust explanation of why impacts cannot be avoided. That is particularly true where land is concerned: every land take must still be justified through the compulsory acquisition process, and the underlying legislative test remains the same. The strongest promoters will not treat flexibility as permission to do less; they will use it to do better through targeted engagement, disciplined issue-tracking and a consultation narrative that can withstand scrutiny.
Then there’s land. Even where consent is secured, projects fail on delivery when land rights can’t be assembled at pace. The implementation push on compulsory purchase is about modernising the mechanics, cleaner notices, more digital process, clearer timetables and, in some cases, earlier possession, so land assembly better reflects infrastructure delivery realities. That matters because land is not an administrative afterthought; it is often the critical path.
What changes on the ground? For project managers on NSIPs, streamlining the process does not mean less work; it means making decisions earlier and resolving issues before submission. That calls for stronger multi-disciplinary coordination, timely design development and open engagement with affected parties so concerns can be understood and, where possible, mitigated before DCO and CPO submission. If the process becomes quicker, more of the outcome will depend on the quality of project management and responsiveness.
Strategic planning is less headline‑grabbing, but it shapes the battlefield. When plans are clear on growth patterns, corridors and infrastructure priorities, promoters spend less time re‑proving “need” and more time solving impacts and delivery. The risk is the handover. If policy updates lag behind investment cycles, uncertainty doesn’t disappear, it relocates. Suddenly the question is not “can we build?”, but “which framework will we be judged against when we submit, and when we are decided?”.
Environmental Delivery Plans (EDPs) could be the most practical lever of all, because they try to replace bespoke, scheme‑by‑scheme mitigation with a strategic route funded by developer contributions. For projects caught in constrained areas, that is potentially transformative: less time arguing about the mechanism, more time delivering the outcome.
Two caveats. EDPs only help where they apply, coverage will be defined by geography and impact type, so teams still need a conventional strategy for everything else. And cost and timing don’t vanish; they change form. The real test will be speed and consistency: how quickly EDPs come forward, how they’re priced, and whether the market can rely on them as a dependable delivery route.
So, will projects actually become easier to deliver? The honest answer is: yes, for some schemes, and not immediately. The reforms target real sources of delay, but the market only feels the benefit once guidance is published, decision‑makers apply it consistently, and project teams adapt how they prepare projects.
It will feel easier where the delays are mainly procedural: prolonged pre-application cycles, avoidable land assembly drag, or post-consent uncertainty. But complex and controversial developments will still require clear justification, constructive engagement and disciplined delivery. The Act is only one part of the picture, and process reform cannot by itself resolve issues such as funding delays, deferred decisions or weak coordination across project teams.
The bottom line is that implementation is likely to reward teams that make decisions early, coordinate well across disciplines and keep land, environment and consenting aligned. Greater flexibility in the system may help strong teams move faster, but it will still depend on the quality of preparation and delivery.
So, what should you do now? Re-baseline programmes around likely commencements, guidance and policy updates, and distinguish clearly between what depends on new rules and what depends on project decisions. Keep engagement focused and evidence-led, bring land and access planning into programme decisions early, and identify which environmental issues may move to strategic routes such as EDPs and which will still require bespoke mitigation.
For promoters, the opportunity is to turn reform into programme advantage. For landowners, it is to get clarity earlier and secure fair outcomes. Either way, implementation is likely to favour teams that engage early, plan land and access carefully, and keep evidence clear and proportionate. That is where we support clients day to day: helping shape practical land and access strategies, supporting engagement, and providing compensation and delivery advice to help schemes progress smoothly.
Handled well, the implementation phase offers an opportunity to improve how projects are prepared, with earlier land strategy, clearer engagement and more decision-ready evidence helping to support delivery.
