Google DeepMind PlanAssist for UK planning

The gist

Latest: Google DeepMind PlanAssist Cuts UK Planning Assessment Time 58%

Planning application backlogs are a persistent constraint on housing delivery in England. A tool that cuts officer assessment time by more than half, if it holds at scale, could materially increase throughput across all English councils.

The full picture

Google DeepMind's PlanAssist, an AI tool built on Gemini, cut the time planning officers spend assessing householder applications by 58% in pilots across Barnet, Camden, and Dorset. More than 70% of AI-generated assessment reports were approved by planning officers without edits. Routine householder applications account for up to 70% of planning officers' workloads. The tool is now moving into a 12-month Beta phase with 12 additional councils, bringing the total to 15, with a planned rollout to all English councils in 2027. Every assessment is reviewed and approved by a qualified planning officer before any decision is made. PlanAssist was developed by Google DeepMind in collaboration with the UK government, Google Cloud, and Faculty.
