Details
- Google DeepMind's PlanAssist pilot with Barnet, Camden, and Dorset councils resulted in a 58% reduction in officer time spent on householder assessment tasks.
- Over 70% of the AI-generated reports were accepted by planning officers without edits, though the author notes this does not independently verify the correctness of every statement.
- The pilot is expanding to a 12-month beta with 15 councils total, including live applications, to test the tool on a larger scale.
- The author cautions that government staffing and process changes may also contribute to any reduction in total waiting times, making it difficult to attribute improvements solely to the AI.
- The tool functions by checking application documents and drawings, reviewing planning policies and site constraints, and drafting a cited report for officer review.
