UK government taps Google Cloud for AI planning tool aimed at near-instant decisions
The UK government has awarded Google Cloud a £6.9 million contract to build an AI tool to speed up planning decisions for the Ministry of Housing, Communities and Local Government (MHCLG). The Department for Science, Innovation and Technology (DSIT) made the award on MHCLG's behalf after a two-week prototype phase.
The goal: cut processing times for planning applications from eight weeks to around four in the near term, with "near-instant decisions for straightforward applications" over time. For busy local authorities under pressure, this is about clearing routine cases faster and freeing planners to focus on complex work.
What the tool will automate
- Policy research and compliance checks
- Generating citations, reports, and documentation
- Identifying material considerations
- Evaluating planning balance
- Drafting decision reasoning
Think of it as an assistant for the high-volume, repetitive parts of casework-while officers retain final say.
Procurement, timeline, and rollout
- Contract value: £6.9 million
- Awarded by DSIT on behalf of MHCLG after a two-week prototype
- Google Cloud selected over AtkinsRéalis UK, Cognizant Worldwide, Endava, and PA Consulting Services
- Contract start: 17 February; runs to 17 May 2028 with a possible 12-month extension
- Initial deployment: householder developments (69% of applications)
- Availability: local planning authorities and other bodies processing applications
Why this matters for government teams
Approvals for new homes recently hit a record low. Around 7,000 housing applications were granted between April and June 2025-the lowest since records began in 1979. Faster decisions on straightforward cases could relieve backlogs and improve public satisfaction without expanding headcount.
Success here looks like measurable time savings, fewer errors in documentation, and better consistency across similar applications, all while maintaining legal defensibility.
What you should do now
- Data readiness: map where case data, policy references, and historic decisions live. Clean up formats and permissions.
- Guardrails: plan for human-in-the-loop review, version control, and auditable decision trails.
- Compliance: prepare Data Protection Impact Assessments and equality impact assessments. Set retention and access rules.
- Accuracy and bias: define acceptance thresholds, sampling plans, and appeal triggers for AI-assisted outputs.
- Change management: train officers on prompts, checks, and overrides. Start with a small pilot and iterate.
- Integration: line up connections with your planning portal and back-office case management systems.
- Transparency: craft clear resident-facing explanations about how AI is used and how to challenge a decision.
- Metrics: track cycle time, rework, appeal rates, and officer satisfaction before and after deployment.
Key numbers at a glance
- Target cycle time: eight weeks down to circa four
- Long-term aim: near-instant decisions for straightforward applications
- Scope first: householder developments (69% of applications)
- Contract term: to 17 May 2028, with a potential 12-month extension
- Supplier: Google Cloud; award by DSIT for MHCLG
