Aipedia: Planning consultants
AI can help draft non-technical summaries and condense technical reports, but a summary that omits or understates a significant effect can mislead decision makers. Environmental information is where errors are most likely to support a legal challenge to a consent.
Part of: AI in Planning consultants
In short
Planning consultants often coordinate environmental statements and write the non-technical summary, planning chapters and topic summaries. AI tools can condense long specialist reports quickly. The risks are omitted significant effects, summaries that differ from the technical chapters, and confident wording that overstates mitigation. Where the consent depends on the environmental information, an error can expose the decision to challenge, delay the scheme and lead the client to claim. If AI produced summaries or analysis in evidence to the Planning Inspectorate, that must be declared.
An environmental statement brings together specialist chapters on topics such as ecology, noise, air quality, landscape and transport. Planning consultants often lead the process and write the introductory, policy and alternatives chapters and the non-technical summary, which must be readable by the public. AI assistants are attractive for turning hundreds of pages of specialist text into short, plain summaries and for checking consistency between chapters.
The AI in planning consultancy overview explains how this sits with other AI uses in planning.
Specialists remain responsible for their chapters; the consultant who summarises them is responsible for the summary.
The duty is reasonable skill and care in preparing and coordinating environmental information, measured against a competent planning consultant. For RTPI members, the Code of Professional Conduct applies. Where AI produced a summary or analysis in evidence submitted to the Planning Inspectorate, including NSIP examinations, it must be declared under the AI casework guidance, with checks described and responsibility for accuracy confirmed. Each expert declares for their own documents.
Illustrative scenario. A consultant uses an AI tool to draft the non-technical summary for a mixed-use scheme. The ecology chapter identified a significant residual effect on a bat roost, but the AI summary reports no significant residual effects on ecology. The summary is relied on in the committee report. After consent, an objector challenges the decision, arguing the public and members were misled. The consent is put at risk, the developer faces delay and legal costs, and it claims against the consultant.
Legal challenges to consents can focus on whether decision makers had accurate environmental information. Even where a challenge fails, it can hold up a scheme for months, and the developer's holding and finance costs build while it is resolved. The consultant's file then becomes evidence: who wrote the summary, what it was checked against, and whether the specialists signed it off. Apex's EIA omission PI scenario shows how an omission in environmental work develops into a professional indemnity claim.
A claim for delay and costs caused by a defective summary is usually a professional negligence claim, and PI commonly responds subject to the terms. Issues include whether the error caused the challenge, how losses from delay are measured, and whether multiple claims from one scheme aggregate (see how aggregation affects PI). Where a consultant coordinates specialists, the policy should reflect that coordination role.
Apex arranges PI for planning consultants who coordinate environmental work, and a broker can review how your cover treats AI-assisted summaries. See also AI in NSIP submissions and AI-drafted planning statements.
It can produce a draft, but each specialist should confirm the summary reflects their chapter, and every significant effect must appear. The summary is read by the public and decision makers, so an omission can mislead them and expose the consent to challenge.
Usually whoever prepared and issued the summary, often the coordinating planning consultant. Specialists remain responsible for their chapters. PI usually responds to the resulting claim, subject to the wording and any coordination terms in the appointment.
Where environmental information is submitted as evidence in Planning Inspectorate casework, including NSIP examinations, AI used to draft, summarise or analyse should be declared. Each expert should declare for their own documents rather than relying on one catch-all statement.
It can be a useful extra check, flagging where chapters use different figures or conclusions. It should not replace a structured review. Confirm that flagged inconsistencies are resolved by the relevant specialist, and that the tool compared final versions rather than drafts.
