What does Rhentech's AI consultancy cover?

Four core offerings, in the order most firms need them, plus cloud AI and executive strategy.

  1. 01

    AI usage audit

    The usual starting point. We find which AI tools your staff use, including shadow AI, which is AI used without the organisation's approval or oversight, and show what data flows into them and what the vendor terms allow.

  2. 02

    AI governance and policy

    A written AI use policy, clear accountability, a fast approval route for new tools and quarterly board reporting, aligned to UK GDPR, ICO guidance and ISO/IEC 42001, the international standard for an AI management system.

  3. 03

    AI implementation and agents

    We choose the use cases that pay back, then design, build and test AI agents that work inside your systems, with human approval for consequential actions and a full audit trail.

  4. 04

    Private and on-premise AI

    Open-weight models running on hardware you control, for work that should never reach a public AI service, such as privileged documents and health records.

  5. 05

    Private cloud AI

    Managed AI models deployed inside your own Azure, AWS or Google Cloud account, with your identities, encryption keys and logs.

  6. 06

    Executive briefing and AI strategy

    A half-day or one-day session that gives your leadership team a shared position on AI, followed by a roadmap with owners, milestones and measures.

How does a Turnkey AI engagement work?

A repeating loop: discovery, analysis, workshop, strategy, implementation, management and review.

  1. Discovery, analysis and workshop

    Understand

    We learn how the business makes money, how AI is used today and where the risk sits, then agree priorities with your leadership in a workshop.

  2. Strategy and implementation

    Deliver

    A written strategy, then projects with milestones: governance, agents, private AI, each tested before staff rely on it.

  3. Management and review

    Run and improve

    A monthly retainer for governance, monitoring and optimisation, with a quarterly review that feeds the next turn of the loop.

What do leaders ask an AI consultancy?

Not answered here? Ask it on the call.

What does an AI consultancy do?

An AI consultancy helps an organisation decide where AI should be used, put the controls in place to use it safely, and implement it. At Rhentech that covers AI usage audits, governance and policy, AI agents, and private or cloud AI infrastructure, with ongoing management if you want it.

Where should we start?

Most firms start with an AI usage audit, to see what is already happening, or with a half-day or one-day executive briefing, to agree a position. Both lead naturally into a policy and a first implementation project.

Why is AI governance urgent for UK firms?

Because adoption is ahead of control. The Cyber Security Breaches Survey 2025/2026 (DSIT, April 2026) found that 31% of UK businesses were using, adopting or considering AI, and only 24% of those had cyber security practices to manage AI risk. Clients, insurers and regulators are starting to ask for evidence.

Does the EU AI Act matter to a London firm?

It can, where your AI systems or their output reach the EU. Article 50 transparency duties applied from 2 August 2026, and the AI Omnibus (Regulation (EU) 2026/1744) moved stand-alone high-risk obligations to 2 December 2027. An AI usage audit shows whether any of your uses are in scope.

How are AI engagements structured and priced?

Entry is a half-day or one-day executive briefing or policy workshop. Implementation runs as projects with milestones, and governance, monitoring and optimisation as a monthly retainer that can be combined with Rhentech managed IT. Fees are agreed in writing before work starts.

Can you keep our data out of public AI services?

Yes. We can deploy models inside your own cloud tenant or on hardware you control, so prompts and documents never reach a public AI provider. We recommend this where the sensitivity of the data justifies it, and say so when a cloud service is the better choice.
