The most common question we receive from CPG and logistics leaders isn't about AI technology. It's about money.
'What does this actually cost?' It's a fair question and one that's almost impossible to answer from a Google search. Most providers don't publish prices. Most comparison pieces are written by people who've never been on either side of the invoice.
This page publishes real £ figures for every AI leadership model available to UK mid-market companies in 2026. We've been on both sides as operators inside $3B+ businesses commissioning these services, and now as providers. So the numbers here reflect both.
What this page covers:

1. The five models and what they actually cost
UK mid-market companies trying to get AI working in their business essentially have five options. Here is what each costs, and what each delivers.
| Model | Entry cost | Ongoing cost | What you get |
|---|---|---|---|
| AI Governance, Risk, and Compliance (GRC) / AI Audit | £5,000 - £9,000 | None — standalone | 2-week diagnostic. 15-page report. 90-day action plan. |
| AI Implementation& Integration Services | £15,000–£25,000 fixed | None — fixed scope | 10-week embedded sprint. Working AI product delivered. Board presentation. |
| AI Change Management & Literacy (Up-skilling) | 3-month initial | £7,500–£18,000/month | Designing training programs for non-technical staff, managing employee anxiety around automation, restructuring roles to complement AI workflows, and fostering an AI-first culture. Data engineering. Quarterly board reporting. |
| AI Strategic Consulting & Advisory | £200,000–£500,000+ | Project-based | Strategy document. No embedded delivery. No data engineering. No sector depth. |
| Fractional CAIO(Chief AI Officer) / AI-as-a-Service (AIaaS) Leadership | £250,000–£400,000/year |
| 4–6 month hire cycle. Role usually undefined on day one. No delivery guarantee. |

2. What does an AI Check cost and what do you get?
Price: £5,000 - £9,000 fixed. Duration: 2 weeks. Commitment: none beyond this engagement.
An AI Check is a structured diagnostic. It audits three things:
- Strategy alignment — does your AI direction connect to board-level business outcomes, or is it a tool list with no P&L anchor?
- Data infrastructure — is your data clean, centralised, and AI-ready, or are your analysts spending 70% of their time cleaning rather than analysing?
- Execution readiness — have previous AI initiatives stalled in committee, or have you got the sponsorship and change management capacity to land a programme?
The deliverable is a comprehensive report plus a prioritised 90-day action plan. It tells you exactly where your AI programme is stalling and what to fix first with commercial specificity, not generic frameworks.
3. What does an AI Implementation & Integration service cost and what do you get?
Price: £15,000–£25,000 fixed. Duration: 10 weeks. Commitment: fixed scope, one engagement.
This is where strategy becomes software. For AI Navi, we call this the FlightPath™ Sprint and it follows a three-phase delivery model:
| Phase | Weeks | What happens |
|---|---|---|
| Navigate | 1–2 | AI strategy aligned to board priorities. C-suite alignment session. Budget unlock narrative built. Quick wins identified. |
| Execute | 3–8 | Data audit and architecture design. One production-ready data pipeline deployed. First AI use case scoped, built, and beta-tested. Working product delivered. |
| Land | 9–10 | Change management plan. Internal team capability sessions. Board presentation with ROI measurement framework. Handover to client team. |
The AI Navi FlightPath™ Sprint is not a strategy document. It is a working AI product. By week 10, your team is using something not waiting for a consultant to return with a deck.
Within the first 30 days of the Execute phase, we deliver a working AI prototype. This is the differentiator that no other fractional provider in the UK market currently offers at this price point.
4. What does a fractional CAIO retainer cost in the UK?
Price: £7,500–£18,000 per month. Commitment: 3-month initial term, then monthly rolling. 30-day notice after month 3.
At AI Navi, our AI FlightScale™ retainer provides ongoing fractional Chief AI Officer leadership plus data engineering capacity. In practice, that means:
- 2–3 days per month — strategic AI leadership, C-suite advisory, board reporting, change management
- 3–5 days per month — data engineering execution, AI product development, pipeline management
- Quarterly board reporting included — ROI measurement framework, progress against 90-day targets, next-quarter prioritisation
The price range reflects engagement intensity. A CPG company in early build phase needing 3 days of data engineering and 2 days of strategic oversight per month will sit toward the lower end. A PE-backed business running two simultaneous AI workstreams with weekly board touchpoints will sit toward the upper end.
Revenue context: 3–5 active retainer clients = £22,500–£90,000 per month in recurring revenue. For comparison, a full-time CAIO at £300,000/year costs £25,000/month before benefits, office, recruitment, and onboarding. The retainer delivers senior AI leadership with sector-specific pladis and Deloitte credentials at a fraction of that. |
5. What does a AI Strategic Consulting & Advisory like the Big 4 AI engagement actually cost?
Minimum engagement: £200,000–£500,000. Typical duration: 3–6 months. Deliverable: strategy document.
Big 4 AI engagements — Deloitte, KPMG, PwC, EY — are structured around strategy consulting, not embedded execution. The team assigned to your project is unlikely to include people who have run data and AI functions inside businesses that look like yours. The strategy document produced is polished and credible to a board. Implementation is a separate engagement, at additional cost.
This is not a criticism — it is a structural reality. Big 4 business models are built for FTSE 250 and above. Mid-market companies (£50M–£500M revenue) are structurally underserved at Big 4 pricing.\
Three things we consistently hear from companies who have run a Big 4 AI strategy engagement before approaching us:
- The deck was excellent. Nothing has been implemented 12 months later.
- The team that pitched it was not the team that delivered it.
- The recommendations were generic. They didn't understand our category dynamics.
6. What does a full-time CAIO cost in the UK?
Salary: £150,000–£250,000 base. Total package: £250,000–£400,000+ (including bonus, benefits, employer NI). Hire cycle: 4–6 months.
Hiring a full-time Chief AI Officer is the right move for some organisations — specifically those with £1B+ revenue, a defined AI function to build, and 18+ months of runway before they need results.
For mid-market companies, the full-time CAIO hire presents three structural challenges:
- The role is almost always undefined on day one — most organisations that think they need a CAIO actually need someone to do what a CAIO does, not to build the function from scratch on an undefined mandate
- Candidate quality at £150–200K in the UK is variable — many CAIO candidates have held the title but have not delivered end-to-end AI transformation at meaningful commercial scale
- The 4–6 month hire cycle means you are 6 months away from any strategic progress before the conversation has even started — and another 90 days before a new hire has diagnosed the situation\
The fractional model exists precisely because of this gap. Senior AI leadership, deployed immediately, without the recruitment cycle, with delivery accountability built into the engagement structure.
7. Full comparison: fractional CAIO vs Big 4 vs full-time hire (UK, 2026)
This is the table your CFO or procurement lead will want to see before any decision is made.\
| Dimension | AI Audit | AI Implementation | AI Advisory | Full-time CAIO |
|---|---|---|---|---|
| Entry cost | £5,000-£9,00 | £15–25K | £200K+ | £250K+/yr |
| Time to first output | 2 weeks | 4 weeks | 3–6 months | 6–£12 months |
| Sector depth (CPG/Logistics) | Yes — insider | Yes — insider | Varies — usually FTSE depth | Depends on candidate |
| Data engineering included | Audit only | Yes — founder-led | Additional cost | Usually not |
| Working software delivered | No | Yes — in 30 days | No | Maybe, eventually |
| Change management | Recommendations | Yes — Land phase | No | Depends on individual |
| Exit mechanism | None needed | Fixed scope ends | Project end | 3–6 month notice |
| Below procurement threshold | Yes (£<25K) | Yes (£<25K) | No | No |
8. Five questions to ask before you choose any AI leadership model
Price is one variable. These questions matter more:
1. What's the deliverable — a document or a working product?
A strategy document has value if the implementation follows immediately. If your organisation has a track record of commissioning strategy and not executing it, a document-led engagement will produce the same result as every previous one. Ask for the deliverable definition in writing before you sign.
2. Who actually does the work?
In Big 4 and mid-tier consultancy models, the senior partner pitches and the junior team delivers. In a two-founder fractional practice, the people in the room for the pitch are the people who do the work. Neither model is inherently superior — but you should know which one you're buying.
3. What happens to your team's capability when the engagement ends?
The measure of a good AI leadership engagement is whether your internal team is more capable at the end than at the start. Engagements that create dependency — where the consultant is needed for every decision because they haven't transferred knowledge — are not in your interest. Ask specifically: what will my team be able to do independently at the end of this?
4. Has the person led AI transformation in an organisation that looks like mine?
A CAIO who has run data and AI at a £3B CPG business understands S&OP cycle constraints, retailer data demands, and promotional trade spend dynamics from the inside. A generalist AI advisor who has read about your industry does not. The difference is not marginal — it's the difference between advice that maps to your actual operational reality and advice that sounds credible until it meets your supply chain team.
5. What does the first 30 days look like?
The first 30 days of any AI engagement tell you everything about what the next 90 will look like. If the first 30 days involve workshops, surveys, and discovery sessions with no output committed, expect the same for months two and three. Ask for a commitment: what will I have at the end of the first 30 days that I can show my board?
9. FAQ: fractional CAIO costs in the UK
How much does a fractional Chief AI Officer cost per month in the UK?
A fractional CAIO retainer in the UK typically ranges from £5,000 to £18,000 per month depending on the number of days per month, the seniority of the individual, and whether data engineering capacity is included. AI Navi’s FlightScale™ retainer runs at £7,500–£18,000 per month and includes both fractional CAIO leadership (strategy, C-suite advisory, board reporting) and data engineering execution.
What is the difference between a fractional CAIO and a full-time Chief AI Officer?
A fractional CAIO provides senior AI leadership for 1–3 days per week rather than full-time. The cost is a fraction of a full-time appointment (£250–400K salary plus benefits), the engagement starts immediately rather than after a 4–6 month hire cycle, and the commitment is flexible. For mid-market companies that need senior AI leadership without a full-time mandate, the fractional model typically delivers faster results at lower cost.
Is a fractional CAIO cheaper than hiring a Big 4 AI consultancy?
Yes, significantly. Big 4 AI strategy engagements start at £200,000–£500,000 minimum and deliver a strategy document without embedded implementation. AI Navi’s entry product — the AI FlightCheck™ diagnostic — is £4,500 fixed. The AI FlightPath™ Sprint, which delivers a working AI product inside 10 weeks, is £15,000–£25,000 fixed. Both sit below most procurement committee approval thresholds.
What does 'fractional' mean in practice?
Fractional means the executive is embedded in your business for a defined number of days per week or month rather than full-time. In practice, this means: weekly or biweekly presence, access for strategic decisions as they arise, and delivery of agreed outputs within the engagement scope. It is not advisory-only — a fractional CAIO should be accountable for delivery, not just recommendations.
How do I know if I need a fractional CAIO or a full-time hire?
If your annual revenue is above £1B and you are ready to build a permanent AI function with a defined team and mandate, a full-time hire may be appropriate. For mid-market companies (£50M–£500M revenue) where AI is not yet a core function but board pressure requires progress, the fractional model delivers faster, at lower cost, with less risk. The FlightCheck™ diagnostic (£4,500, 2 weeks) is designed to answer this question for you — it tells you exactly what AI leadership structure your business needs and why.
10. What happens next
If you have read this far, one of three things is probably true:
- Your board has asked for an AI strategy and you are under pressure to produce one that connects to commercial outcomes, not a vendor shortlist
- You have run an AI pilot that didn't make it to production, and you are trying to understand what went wrong and what a credible path forward looks like
- You are about to make a significant AI leadership decision — a hire, a consultancy engagement, or a technology platform — and you want a second opinion from someone who has been on both sides
In any of those cases, the right first step is the AI FlightCheck™.
Two weeks. A 15-page report that tells you exactly where your AI programme is stalling and what to fix first. No commitment to anything beyond that.\
