“The way we have worked with Great Wave has given us the trust and control to deploy AI, get feedback from our users on what is working and what is not, and make the adjustments needed.”

What's live at Warwickshire Police
Each agent recommends, checks or flags. Decisions stay with officers, supervisors and authorised staff.
Overtime claim evaluation
Checks claims submitted through a Power App against force policy, shift patterns, duties and entitlement rules, then gives an outcome for human review.
£147k total annual benefit
£72k in time saved on manual checks, plus £75k cashable from fewer incorrect payments.
Crime classification support
Analyses crime reports against the Home Office Counting Rules and recommends a classification. Authorised staff review and confirm it.
More accurate, consistent crime data
Fewer records for the Force Crime Registrar team to reclassify downstream.
Investigation standard audit
Audits investigation quality against defined standards and highlights findings for authorised staff to review.
Up to 140 crimes audited by one person in a day
Previously, 20 officers audited around 40 crimes a month between them, at 30–60 minutes each.
Investigation review
Reviews eligible investigation records against policy and standards, and presents potential gaps to the supervisor, who completes the review.
Around 10 minutes saved per review
Current estimate. Frees supervisors to support officers and manage risk.
Figures are taken from the signed-off Warwickshire Police case study. The investigation review time saving is an estimate.
“We are bombarded every day with solutions and ideas, all claiming to be powered by AI. Some are genuinely innovative; others are little more than distractions. The question is no longer whether we can adopt AI, but whether we should, where it adds value, and how we do so responsibly. Organisations need a trusted partner to help them build enterprise-scale AI that delivers early benefits while remaining secure, scalable, and sustainable for the future.”

Built in-house, at low cost
- One person, the whole lifecycleA technical Business Analyst builds, tests and releases every agent, with end users helping on design and testing.
- Works with what the force already hasAgents link into existing Power Apps and RPA rather than replacing them.
- Very low running costsFrom around £30 a year for a simple agent to £9k a year for a complex one.
Secure and governed from day one
- Data stays under force controlNever shared with third parties or used to train external AI models.
- People stay accountableAgents are approved with operational leads and information governance before release, and humans make every final decision.
- Compliance designed inSupports UK GDPR, the Data Protection Act 2018 and Law Enforcement Directive requirements, with role-based access, audit logging and encryption.
- Tested before trustNo agent reaches operational use without testing first.
Generative AI in policing: common questions
What did Warwickshire Police achieve with generative AI?
Warwickshire Police has six generative AI workflows live in operational use. They have saved 10,560 hours, released the capacity of more than six operational and supervisory roles each year, and the overtime claim evaluation workflow alone delivers £147k in total annual benefit.
How does Warwickshire Police use generative AI securely?
The Great Wave AI platform runs on the force's own infrastructure. Data is never shared with third parties or used to train external AI models, and humans make every final decision. Each agent is approved with operational leads and information governance before release. The setup supports UK GDPR, the Data Protection Act 2018 and Law Enforcement Directive requirements, with role-based access, audit logging and encryption.
Do you need a team of AI engineers to build police AI agents?
No. At Warwickshire Police a single technical Business Analyst builds, tests and releases every agent, with end users helping on design and testing. The first working prototype was ready within 24 hours, and running costs range from around £30 a year for a simple agent to £9k a year for a complex one.
What are the live AI workflows at Warwickshire Police?
Four are described here. Overtime claim evaluation reaches 97% accuracy against a 73% manual baseline. Crime classification support reaches 91% against 70%. Investigation standard audit lets one person audit up to 140 crimes in a day. Investigation review saves around 10 minutes per review, which is an estimate.
Does the AI replace existing police systems?
No. The agents link into the force's existing Power Apps and RPA rather than replacing them. They recommend, check or flag, and decisions stay with officers, supervisors and authorised staff.
