Planning case preparation that keeps pace with application volumes

The situation

A district council planning team in the South East was carrying a persistent backlog. Application volumes had risen, consultation responses had grown longer, and each case required officers to digest applications, plans, policy documents, objections and case history before a recommendation could be drafted.

Experienced officers were spending their evenings summarising objections rather than exercising the professional judgement they were hired for. Recruitment was not closing the gap, and a previous attempt to use a generic AI tool had stalled over accuracy concerns — summaries that could not cite their sources were unusable in a quasi-judicial process.

What we did

Discovery sessions with officers traced three cases end to end. The pattern was clear: 60–70% of preparation time went on reading and summarising material, not on assessment. We designed a planning support workflow around exactly that: application summaries with source references, constraint extraction, policy cross-checks against the local plan, structured summaries of objections and consultation responses, and first-draft case notes in the council’s template.

Every generated summary cites the document and page it came from, so officers can verify in seconds. The system flags missing documents at validation rather than at week six. Officers were trained in pairs on live cases, and a governance note agreed with legal services records how AI-assisted preparation is disclosed.

The human role

Planning officers retain professional judgement and decision responsibility on every application — without exception. The system reads, organises and drafts; the officer assesses, weighs and recommends. Committee reports remain officer-owned documents, and the team’s sign-off process is unchanged.

Results

First-draft case notes are produced around 45% faster against the agreed baseline, returning roughly a day a week to each officer. The team is processing more applications per officer per month than before the engagement, the determinations backlog is shrinking quarter on quarter, and consultation summaries are more consistent than the manual versions they replaced.

“Nothing about the decision has changed — and that was the point. What changed is that my officers spend their time on judgement, not on retyping objections.”

What the client keeps

The planning support workflow and its prompt library, the citation and verification procedure, the governance and disclosure note, nine trained officers, and an internal owner who adjusts policy cross-checks as the local plan evolves.
