UK: DeepMind's AI for Permits Targeted for 2027

After tests in Barnet, Camden, and Dorset, an AI-based housing application assistant is entering a 12-month beta phase. Pilot programs report an average time savings of 58% and over 70% of reports accepted. Subject to success, the government aims for a rollout to all English councils by 2027, with systematic validation by qualified agents.

2027 Goal and Human Oversight Remain in Place

If the tests prove successful, the UK government plans to offer PlanAssist to all councils in England by 2027. Before any decision is made, a qualified planning officer must review and validate each assessment. The tool is beginning a twelve-month beta phase, relying on real-world applications, launched with a small group of councils. The involved councils cover both metropolitan and rural districts to test PlanAssist in varied contexts.

Pilots: 58% Less Time and 70% of Reports Validated

During experiments conducted since June in Barnet, Camden, and Dorset, PlanAssist has reduced the average time spent by agents on housing application assessments by 58%. More than 70% of the reports generated by the tool were accepted without modification by the agents. These results come as current applications account for up to 70% of agents' workloads and take up a disproportionate amount of their time. Current delays hinder progress toward the government's goal of building 1.5 million new homes by 2029 and can lead to several months of waiting for approval of simple home improvement projects.

Key Features, Technical Consortium, and Scaling Up

PlanAssist was developed by Google DeepMind in collaboration with the UK government, Google Cloud, and Faculty, and is based on Gemini. The tool automates the processing of applications and the drafting of assessment recommendations. It reviews documents and architectural plans, analyzes files against heritage constraints and planning policies, identifies any prior objections, and produces fully sourced reports that can be modified by agents before decision-making. The final decision on each application rests with the planning officers. Following the announcement of an opening to 12 new authorities, three groups of four councils will be added to the trial, bringing the total to 15. The opening of access to these new councils is the next step in the timeline.
