ACP insights & guidance
England’s National Scheme of Delegation commenced on 31 October 2026. It sets the framework for which planning functions officers or committees can determine. For an applicant, an early practical step is to confirm the route with the local planning authority and make the technical submission easy to check whichever route applies.
Confirm the decision route and the evidence requirements
Ask the authority which provision and current scheme apply. Check whether any category, exception or referral process is relevant and who decides that question. Track the development description and drawing revision used in the enquiry.
Then confirm the separate technical requirements. An officer-led decision can still require evidence on significant environmental effects, compliance with local policy and how mitigation will be secured. Existing EIA, habitats and other requirements continue to depend on their own legal tests and the proposal.
Give each assessment a decision to support
Use one index that makes the relationships clear. For each assessment record the relevant policy or validation item, the assessed drawing or scenario, the main finding and where any mitigation is secured. Also identify unresolved questions and who owns each one.
- For noise and air quality, note whether the assessment assumed particular equipment, routing, opening hours or façade design.
- For drainage, identify the submitted strategy, receiving route and the maintenance information that supports delivery.
- For ecology, distinguish survey evidence, embedded mitigation and measures that need a separate approval or management commitment.
Illustrative example
A site plan moves a proposed access after the transport assessment was issued. The change may affect traffic, noise and air quality assumptions. Update the evidence index to flag the revised drawing, identify the consultants who must review it and record whether each report needs amendment. This is more useful to the officer than an unexplained bundle of documents with inconsistent revision dates.
Before submission, ask a colleague unfamiliar with the scheme to find the current plan, the key mitigation and the outstanding questions. If that takes several documents and a phone call, improve the index.
Common question
Does officer determination change the environmental reports required?
Confirm both the decision route and the applicable evidence requirements with the authority. The underlying environmental tests have separate legal bases.
