UK councils trial Google DeepMind AI tools that could cut householder planning decisions from 8 weeks to 4 weeks and digitise documents in 40 seconds, aiming

A new AI prototype built with Google DeepMind is being piloted in Barnet, Camden and Dorset to cut the average householder planning decision time from eight weeks to four, while a companion tool called Extract can turn two‑hour document checks into 40‑second jobs, promising a national rollout by spring 2026 [1][2][3].

| At a glance | |
|---|---|
| Prototype decision‑time reduction | 8 weeks → 4 weeks |
| Councils testing prototype | Barnet, Camden, Dorset |
| Extract digitisation speed | 2 hours → 40 seconds per document |
| Planned national rollout | Spring 2026 |

## Faster decisions for routine applications  

The prototype, co‑created by the UK government, Google DeepMind, Google Cloud and planning‑authority partners, triages applications, summarises key information and offers an initial assessment for planners to review. Householder applications—nearly 70 % of the 350 000 annual submissions—are the focus, meaning planners could redirect time from routine cases to complex housing projects if the trial meets its target [1]. The government aims to halve the processing time for these straightforward cases, a change that would free thousands of officer hours and help meet the 1.5 million‑home building target set by Parliament.

## Extract turns paperwork into data in seconds  

Extract, the second AI tool, uses Google’s Gemini multimodal model to convert historic planning maps, handwritten notes and other paper records into structured digital data in about 40 seconds—down from the typical two‑hour manual effort [2][3]. Trials across four councils showed the same speed gain, and the tool is expected to save an average council roughly 255 hours of manual work per year, cutting the national estimate of 250 000 hours of annual labour on document checks [1][3]. The government plans to make Extract available to every English council by spring 2026, fulfilling a promise made in the previous parliamentary session [1][2].

## What to watch  
- **Spring 2026 rollout** – monitor the government’s progress on delivering Extract to all 350 000 planning applications.  
- **Decision‑time metrics** – watch for published results from the Barnet, Camden and Dorset pilots to see if the four‑week target is achieved.  
- **Sector response** – observe whether other UK public‑service bodies adopt similar AI tools, potentially expanding the market for generative‑AI applications in local government.

If the trials deliver the promised speed gains, AI could become a core productivity lever for UK local authorities, reshaping how planning departments allocate staff and accelerating the delivery of new housing across the country. The open question remains whether the technology will scale without compromising the quality of complex planning judgments.
