English Councils to Trial Google AI Tool to Speed Up Planning Decisions
Several English local councils are set to begin trials of an artificial intelligence planning tool developed by Google, in a move that could fundamentally reshape one of the most bureaucratic and contested functions of local government. The technology is designed to analyse planning applications and make initial recommendations, with the aim of cutting through backlogs that have become a significant obstacle to housebuilding and infrastructure delivery across England.Background
The planning system in England has long been identified as a critical bottleneck in the country's ability to build the homes and infrastructure it needs. Local planning authorities are chronically understaffed, with many councils struggling to recruit and retain qualified planners in the face of competition from the private sector. The result is a system in which applications can take months or even years to be decided, creating uncertainty for developers, homeowners, and communities alike.
The Labour government has made planning reform a central plank of its economic strategy, setting an ambitious target of 1.5 million new homes over the course of this parliament. Achieving that target requires not only changes to planning policy — including the restoration of mandatory housing targets for local authorities — but also a significant improvement in the speed and efficiency of the planning process itself. The government has already announced additional funding for planning departments and changes to permitted development rights, but the backlog of undecided applications remains a serious problem.
The use of technology in planning is not new: many councils already use software to manage applications and track progress. But the deployment of advanced tools capable of reading and interpreting complex planning documents, assessing applications against local policies, and generating recommendations represents a qualitative step change in how the system operates.
Key Developments
The trials, reported by the Financial Times, will see participating councils use Google's tool to process incoming planning applications. The technology is designed to read application documents, cross-reference them against local development plans and national planning policy, and produce an initial assessment of whether the application should be approved or refused. Planning officers would then review the recommendation before making a final decision.
The initiative is part of a broader push by the government to modernise public services through technology, and follows similar experiments in other areas of local government administration. The trials are expected to be closely monitored by the Ministry of Housing, Communities and Local Government, which is considering whether to roll out similar tools more widely if the pilots prove successful.
The use of such tools in planning decisions raises significant questions about accountability and transparency. Planning decisions are quasi-judicial in nature, and applicants have a right to understand the reasoning behind any refusal. Critics have raised concerns about the potential for algorithmic bias — particularly in relation to applications from smaller developers or in areas with complex heritage or environmental constraints — and about the liability implications if an assisted decision is subsequently overturned on appeal.
Why It Matters
The planning system is one of the most consequential functions of local government, shaping where people live, how communities develop, and what infrastructure gets built. The chronic inefficiency of the current system has real costs: delayed housing developments mean higher rents and house prices; delayed infrastructure projects mean congested roads and inadequate public services. If these tools can genuinely accelerate decision-making without compromising quality or fairness, the benefits could be substantial.
This is the first time a major technology company has partnered directly with English councils on assisted planning decisions of this nature, and the trials will be watched closely by local authorities across the UK and Ireland. Unlike Scotland, which has its own planning system and has been exploring digital tools separately, England's approach will set a precedent for how technology is integrated into statutory decision-making processes. The outcome of these trials could also influence the government's forthcoming Planning and Infrastructure Bill.
Local Impact
For communities across England, the practical impact of faster planning decisions could be significant. Families waiting for extensions to be approved, small businesses seeking permission for new premises, and housing associations trying to build affordable homes all stand to benefit if the backlog is reduced. In Northern Ireland, where the planning system is devolved and managed by the Department for Infrastructure, officials will be watching the English trials with interest. The Planning Appeals Commission in Belfast already faces significant delays, and any technology that demonstrably improves throughput in England is likely to prompt calls for similar pilots in Northern Ireland.
What's Next
The trials are expected to begin in the coming weeks, with participating councils yet to be publicly named. An initial evaluation is expected within six months, with a decision on wider rollout to follow. The government's Planning and Infrastructure Bill is expected to receive its second reading in the House of Commons before the summer recess. Ministers have indicated they will consider amendments to facilitate the use of technology in planning if the trials produce positive results.
