Google AI to Help Decide Planning Applications in England- England is set to trial a new artificial intelligence system developed by Google to assist in planning decisions, marking the first time AI will play a formal role in determining whether building projects should be approved or rejected.
The tool, known as the Augmented Planning Decision Tool, will generate recommendations on planning applications before final decisions are signed off by council officers. A small group of local authorities is expected to begin testing the system within weeks, with ministers aiming for a nationwide rollout if the pilot proves successful.
The initiative forms part of a broader government effort to modernise public services and improve efficiency through digital technology. Officials hope the system could significantly reduce delays in the planning process, with ambitions to cut decision times in half. The move comes as the government struggles to meet its target of delivering 1.5 million new homes during the current parliament.
By combining digitised planning data—such as property boundaries, conservation areas and local policies—with AI analysis, the system is designed to rapidly assess applications and produce structured, “reasoned” recommendations. It is also expected to help councils manage a growing volume of submissions and objections, including those generated using AI tools.
James Murray, chief secretary to the Treasury, has been among the leading advocates for expanding AI use across government. He has argued that the greatest benefits will come from rethinking entire processes to make them faster and, where possible, automated. In the context of planning, that could mean reducing the administrative burden on both applicants and local authorities.
The government awarded an £8.3 million contract earlier this year to build the system, with the aim of enabling more consistent and transparent decision-making. Supporters say the technology could help planners navigate increasingly complex rules and large volumes of documentation, particularly in major development proposals.
However, the rollout has raised concerns among planning professionals and industry experts, who warn that efficiency gains must not come at the expense of quality or public trust.
Daniel Slade of the Royal Town Planning Institute cautioned that AI should not replace human judgment in a field that often requires balancing technical considerations with local knowledge and community values. He warned there is a risk that planning systems could become overly shaped by what works best for AI, rather than what delivers the best outcomes on the ground.
“There’s little benefit in speeding up decisions if the developments themselves are poor quality,” he suggested, adding that transparency and professional discretion remain essential.
Others have pointed to potential challenges around public confidence. Matthew Spry of Lichfields said there may be skepticism about decisions perceived to be influenced by machines, even if officials retain final authority. This could be particularly sensitive in large or controversial developments, where community opposition is often strongest.
At the same time, some experts see clear advantages in using AI as a support tool rather than a decision-maker. By analysing large datasets, consultation responses and technical reports, AI could help planners organise information more effectively and identify key policy considerations. This, in turn, could allow human decision-makers to focus on more complex judgments.
Questions have also been raised about how such systems are trained. If AI models rely heavily on historical planning decisions, there is a risk they could reinforce outdated policies or existing biases, potentially conflicting with current government priorities aimed at accelerating growth and development.
Ministers have stressed that the technology will remain advisory, with human oversight built into every stage of the process. For more complex cases, the system is expected to provide a framework for decision-making rather than a definitive recommendation.
The government says the initiative reflects a wider commitment to harness innovation in tackling long-standing challenges in housing and infrastructure. With planning delays frequently cited as a major barrier to development, officials hope that integrating AI into the system could unlock faster approvals while maintaining accountability.
As the pilot begins, its success is likely to depend not only on technical performance but also on whether it can gain the trust of planners, developers and the public alike.
