# Google PlanAssist: Gemini Planning Tool Expands to 15 Councils

A wider English council beta will test whether early time savings survive real applications, local policies and human review.

Google DeepMind's Gemini-powered PlanAssist is moving into a 12-month beta involving 15 English councils. The tool helps planning officers assess householder applications and draft reports. Early pilots reported a 58% reduction in officer assessment time, but the expansion will test whether those results hold across more councils.

The [October 31 DeepMind announcement](https://deepmind.google/blog/speeding-up-planning-decisions-with-ai/) adds 12 authorities to the original Barnet, Camden and Dorset pilots. This is an expansion of work begun in June, not a newly launched public chatbot for homeowners.

## What PlanAssist actually does

PlanAssist checks application documents and drawings for required information, examines policy and site constraints, considers earlier objections, and drafts cited assessment reports. Officers can edit those reports and retain responsibility for the decision.

Google developed the tool with the UK government, Google Cloud and Faculty. DeepMind says more than 70% of reports generated during the pilot were accepted by officers without edits. That is a report-review result, not an independently established accuracy rate or permission for the system to approve applications itself.

The workflow is useful because it connects document checking to the evidence an officer needs. A general chatbot answer still leaves someone assembling the application, relevant policies and constraints. Putting those materials into a reviewable report could reduce that repeated preparation work, provided the citations and conclusions withstand checking.

## Where PlanAssist is available

The additional councils will join in three cohorts. DeepMind describes a beta using live applications, with wider English availability in 2027 conditional on successful testing.

The [government's October 30 announcement](https://www.gov.uk/government/news/faster-planning-decisions-as-new-rules-and-ai-tackle-delays) names the new participants: Ashford, Lambeth, Newcastle, Nottingham, Bristol, Cumberland, North Lincolnshire, Rochdale, Redbridge, South Gloucestershire, Stoke-on-Trent and Westminster.

Officers will use PlanAssist alongside their normal process. The government says it will not be mandatory software and intends to make it available to every English council by the end of 2027. Neither announcement offers a general self-service signup, public API or commercial price.

## What the 58% result does and does not show

**Less officer assessment time is not the same as a guaranteed shorter wait for every applicant.** The result comes from early testing in three councils. A planning application can also depend on missing documents, consultations, objections and work elsewhere in the process.

The wider beta can test whether a report remains useful when local rules, document quality and application types change. The share of reports needing correction matters, but so does the effort required to check a report that initially looks complete.

For public-sector AI, keeping a human decision-maker is only part of the design. That person needs evidence they can inspect and enough time to challenge it. PlanAssist's next meaningful result will be whether it reduces total work while preserving that review, rather than simply producing the first draft faster.
