Google DeepMind's PlanAssist expands to 15 UK councils after cutting review times by 58%
AI tool designed to streamline routine planning applications moves into 12-month beta phase across England.
What to know
- PlanAssist reduced planning officer time on routine applications by 58% in pilot testing across three councils, with over 70% of AI-generated reports approved by officers without edits.
- The tool expands to 15 councils for a 12-month beta phase, with plans for nationwide deployment to all English councils by end of 2027.
- Householder applications account for up to 70% of planning workloads but represent straightforward decisions; automating their processing frees officers to focus on complex cases.
- Human oversight is maintained: planning officers retain final decision authority on every application, and all AI-generated reports are editable before approval.
“Subject to successful testing, the government plans for the tool to be made available to all councils in England in 2027, with every assessment reviewed and approved by a qualified planning officer before any decision is made.”
