Government Unveils AI Planning Tools Targeting Half-Time Decisions

The government has unveiled two AI tools designed to fundamentally accelerate England’s planning system – a development with direct and significant implications for the construction supply chain, where planning delay remains one of the most persistent and costly constraints on project delivery.

The first is a new AI prototype, developed in partnership with Google DeepMind, Google Cloud, Faculty and local planning authorities, currently in early-stage testing with Barnet, Camden and Dorset councils. The tool triages householder planning applications, summarises key information and provides planning officers with an initial assessment, with the target of cutting average decision times from eight weeks to four. If trials prove successful, a nationwide rollout is planned by 2027, with every assessment reviewed and approved by a qualified planning officer before any decision is made.

The second tool, Extract, is available to every local planning authority in England, delivering on a commitment made by the Prime Minister last year. Extract uses AI to convert decades-old planning documents, maps and handwritten records into useable digital data in minutes, eliminating an estimated 250,000 hours of manual officer work annually. Trials across 20 local planning authorities including Exeter and Hillingdon found it saves the average council around 255 hours of document processing – down from over 500 – freeing planning officers to focus on the complex, high-value decisions that directly affect development pipelines.

Why this matters for the construction supply chain

Householder applications account for nearly 70% of all planning applications submitted in England each year – around 350,000 applications annually, and their processing backlog has a compounding effect on the wider system. When planning officers are buried in routine householder cases, capacity for complex applications, major housing schemes and the infrastructure development programmes the construction supply chain depends on is squeezed. Faster processing of straightforward cases is not just a consumer convenience; it is a systemic unlock for the entire planning pipeline.

Housing and Planning Minister Matthew Pennycook was direct: “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.”

For housebuilders, developers and the contractors and specialists who work within their supply chains, the government’s stated ambition to build 1.5 million homes this Parliament is only deliverable if the planning system can process applications at the required pace. The Extract tool’s digitisation of historic planning records also has a less visible but commercially meaningful benefit — creating accessible, high-quality planning data that reduces the time and cost burden on developers and their consultants when assessing site history, constraints and local policy context.

Marc Warner, CEO of Faculty, framed the downstream impact clearly: “This will give councils more time and resource to focus on the bigger infrastructure projects that will improve communities and drive economic growth.”

The digital planning data opportunity

Extract’s nationwide availability also signals a broader shift in the planning data landscape that the construction supply chain should be tracking. As decades of paper-based planning records are converted into structured digital data, the quality and accessibility of the information underpinning site assessment, due diligence and development appraisal will improve materially. Businesses in planning consultancy, site finding, PropTech and development data services should be assessing how this changing data environment affects their offer and their clients’ workflows.

The AI planning prototype complements regulations laid in Parliament earlier this month to overhaul planning committees through a new National Scheme of Delegation – speeding up decisions on larger home extensions and loft conversions further, and reducing the volume of applications requiring full committee consideration.

Relevant supply chain capability areas:

• Housebuilding, residential development and volume construction
• Planning consultancy and development management
• PropTech, planning data and site assessment platforms
• Digital document management and data conversion services
• Major infrastructure and mixed-use development
• Affordable housing delivery and registered provider supply chains
• Civil engineering and enabling works for residential schemes
• Building products and materials supply for householder improvement works
• Architectural and technical design services

The AI planning prototype is currently in testing with Barnet, Camden and Dorset councils, with nationwide rollout targeted by 2027. Extract is available to all local planning authorities in England from today via MHCLG’s Digital Planning programme. Further information at ai.gov.uk.
