AI tool to slash planning decision times as government accelerates push to build 1.5 million homes

Millions of homeowners waiting for permission to extend their homes, convert lofts or make other improvements could see faster decisions, with 2 new AI tools unveiled today (Wednesday 17 June) to modernise England’s planning system.

The first is a new AI prototype that aims to halve the time it takes to process householder planning applications – down from 8, to 4 weeks in an average case.

It is in early stage testing with Barnet, Camden and Dorset councils. The prototype triages applications, summarises key information and provides planning officers with an initial assessment they can consider when making their decision. It has been created by government together with Google DeepMind, Google Cloud, Faculty and local planning authorities.

The second is that another tool, Extract, is now available to all councils in England as promised by the Prime Minister last year.  It uses AI to help planning officers convert decades-old planning documents and maps, sometimes with handwritten notes, into readily useable data in minutes.

Householder applications account for nearly 70% of planning applications each year. By reducing the time spent on straightforward cases, the prototype being tested in Barnet, Camden and Dorset could help planning officers focus more on complex applications, including new housing and major developments communities rely on.

If successful, the technology will be rolled out nationwide by 2027 – with every assessment reviewed and approved by a qualified planning officer before any decision is made.

The announcement marks another step in the government’s commitment to build 1.5 million homes and use technology to improve public services.

Minister for Data and Modern Digital Government Ian Murray said

When someone wants to add a bedroom or convert their loft, they shouldn’t be waiting months for a straightforward decision. And planning officers shouldn’t be spending hours digging through decades of paper records when making the decisions that really matter.

These tools give planning officers better support to make quicker decisions – and give families the answers they deserve, faster.

This isn’t about replacing the expertise and judgement of planning professionals; it’s about taking admin off their desks so they can focus on the skilled work their communities need most.

Housing and Planning Minister, Matthew Pennycook said

Our planning system remains heavily reliant on cumbersome paper-based processes that consume the time of expert planning officers and cause delays on even the most routine types of application.

We are dragging the system into the twenty-first century by harnessing the power of AI to streamline the planning application process, freeing up planners to make quicker and better decisions and reducing unnecessary delays.

Naisha Polaine, Executive Director for Growth at Barnet Council said 

The tool’s ability to collect relevant information, undertake a provisional assessment, and draft the foundations of a report has the potential to save significant officer time spent working on the administration of planning applications and direct this to speeding up the decision-making process for residents.

In turn, this will contribute significantly to delivering our house building growth targets in the borough.

From today, Extract is now available to all local planning authorities in England. It will slash the estimated 250,000 hours a year spent by planning officers manually checking these documents. Digitising and publishing these documents, as data, helps officers and the public access high-quality planning data more easily, and create the right foundation for the next generation of tools that could dramatically reduce delays that plague the system.

Around 350,000 planning applications are submitted a year in England, yet the system remains heavily reliant on checking old documents. For every application, planning officers must check the local planning rules that apply, many of which are hidden away in hundreds of pages of documents, before reaching a decision.

This represents a step-change in productivity, freeing up thousands of hours for planning officers to focus on decision-making to speed up housebuilding. It will also accelerate the delivery of much-needed housing, improve reliability in the planning process, reduce costs and save time for councils and developers.

It comes as the government laid regulations in Parliament earlier this month to overhaul planning committees – speeding up decisions on small planning applications, such as larger home extensions and loft conversions, through a new National Scheme of Delegation. 

Marc Waner, CEO of Faculty, CTO of Accenture, said

For decades, England’s gummed up planning system has slowed families seeking simple home improvements – like new windows, or attic conversions.

By using AI to support planning officers with clear recommendations – with humans retaining final sign off – we will help cut approval times on simple renovations in half.

This will give councils more time and resource to focus on the bigger infrastructure projects that will improve communities and drive economic growth.

Lila Ibrahim, Chief AI Readiness Officer, Google DeepMind said  ​​​

The UK has an opportunity to build the homes our communities need, but local councils face a mountain of paperwork.

That’s why we’re co-creating a sophisticated planning tool directly with councils to solve real-world bottlenecks. This will help significantly cut decision times, freeing up planners to focus on the future to get Britain building faster.

Following trials across 20 local planning authorities in England including Exeter and Hillingdon, Extract is expected to save the average council around 255 hours of manual work digesting documents into digital form. This is down from more than 500 – giving staff more valuable time back to focus on complex work that delivers value for the communities they serve.

Last year the Prime Minister announced that Extract would be made available to every local planning authority in England by Spring 2026 – today the government is delivering on that commitment.  

Extract was developed by the government’s expert applied AI team, the Incubator for AI (i.AI), working with MHCLG’s Digital Planning programme. You can read more about i.AI’s work on https//ai.gov.uk/.

Notes to editors 

APD is being developed under an MHCLG contract with Google  Cloud, Google DeepMind, and UK AI company Faculty as delivery partners. Alpha trials began in May 2026.

MHCLG is funding APD (Augmented Planning Decisions) with an £8.2million contract with Google Cloud, Google DeepMind and delivery partner Faculty.

Subject to successful results, the government expects to expand trials to up to 10 additional councils later in 2026, with national rollout planned from 2027.

You can find out more about Extract at Extract – Check and provide your planning data including a video demonstration. It is available for use by local authorities.. It is a specialist tool to support planning officers and council workers; it does not replace them.

As part of Extract’s rollout, the goal is that three national planning datasets – Article 4 Directions, Conservation Areas, and Tree Protection Orders – will be published on the Planning Data Platform.

AI support for householder applications will help planning officers to make recommendations; people will remain the final decision makers.

Around 350,000 planning applications are submitted in England every year. Householder applications make up the majority of local planning authority workloads.

Maureen Costello, Vice President, UK, Ireland and Sub-Saharan Africa, at Google Cloud said

True digital transformation happens when advanced innovation is built on a resilient, secure foundation. Google Cloud is proud to partner with the UK Government to bring AI out of the lab and into production-ready public services to deliver faster outcomes for councils nationwide.

Graham Stallwood, Interim Chief Executive at the Planning Inspectorate said 

The Planning Inspectorate is following closely the work being led by MHCLG and Local Authorities to enable greater use of new AI-enabled tools like Extract and the Augmented Planning Decisions Prototype. 

 AI guidance provided by the Planning Inspectorate upholds public and professional responsibility for the information generated and supports human control and oversight. We will keep our guidance under review to maintain this ‘golden rule’ for AI use, as this technology improves and we understand more about the impact on any casework.

Mike Keily, Chair of the Planning Officers Society said

The Planning Officers Society welcomes this key announcement along our Digital Planning journey. Extract is a game changing tool as it unlocks the data trapped in PDFs and makes it available in digital form to be used by AI and other systems. We look forward to future announcements from MHCLG as their investment bears fruit.

Sarah McLaughlin, spokesperson for the Association of Directors of Environment, Economy, Planning and Transport (ADEPT) said  

ADEPT welcomes digital advancements that support efficiency, transparency and effective decision-making. By embracing innovative technologies, local authorities can streamline processes and deliver improved outcomes for communities and businesses. Digital innovation enables more collaborative, accessible and future-focused planning, helping towns and communities adapt to changing needs, while supporting economic growth, environmental responsibility and high-quality place-making.

Dr Wei Yang OBE, CEO at the Digital Task Force for Planning said

High-quality, standardised planning data is essential for a modern planning system. Extract can help local planning authorities accelerate the transition from document-based processes to data-enabled planning by making it easier to convert existing planning information into usable digital data. This represents an important step forward in improving efficiency, transparency and evidence-based decision-making across the planning system.
