How long does a typical AI consultancy engagement last?

Most engagements run between four and twelve weeks, depending on scope. A readiness audit typically takes four to six weeks. A full strategic roadmap takes six to eight weeks. Fractional CAIO arrangements are ongoing, usually on a monthly retainer basis.

What is the difference between a Fractional CAIO and ad-hoc advisory?

A Fractional Chief AI Officer provides ongoing, structured leadership - attending board meetings, shaping AI strategy and overseeing AI initiatives. Ad-hoc advisory is project-based support for specific decisions or evaluations. Fractional CAIO suits organisations embedding AI long-term; ad-hoc works for one-off strategic questions.

How long does it take to see ROI from AI consultancy?

In our experience, measurable productivity gains arrive within three months. What makes the difference is whether recommendations are tied to specific, baselined outcomes (time saved, cost avoided, revenue opportunity) rather than vague promises. Our engagements track ROI from day one, against baselines set in the readiness audit.

What if our team has no experience with AI at all?

That is completely normal for most SMEs we work with. We typically recommend starting with AI training to build a shared foundation across your team, then moving into consultancy once leadership has enough context to make informed strategic decisions.

What happens in a first consultancy session?

We start with a discovery conversation to understand your business goals, current capabilities and concerns about AI. From there, we scope a readiness audit or targeted assessment. You leave the first session with a clear understanding of next steps and expected timelines.

How do you measure ROI from AI consultancy?

We tie every recommendation to specific, measurable outcomes - time saved, cost avoided, revenue opportunity or risk reduced. After implementation, we track these metrics against the baseline from your readiness audit.

What is the 30% rule in AI?

We have not found a recognised source for a '30% rule' in AI: the phrase is used online for several different ideas. What we apply instead is simpler: a person reviews any decision AI contributes to, and we start with the projects most likely to succeed.

Which is the best AI for business advice?

There is no single best tool. General AI assistants are useful for research, drafting and testing ideas, but they do not know your business, your data or your risks. In our experience, they work best alongside advice from someone who does. Our guide to getting started with AI covers how to choose a first tool for your business.

Trusted by organisations across the UK

What is a fractional Chief AI Officer and why do UK SMEs need one?

IBM Institute for Business Value

A fractional CAIO gives your organisation executive-level AI leadership on a part-time basis. Instead of the cost of a full-time executive hire, you get structured strategic guidance, team training and board-level decision support at a fraction of the cost. For SMEs looking to hire AI consultant expertise with leadership-level strategic support, a fractional model is often the most practical route.

According to IBM's Institute for Business Value (opens in a new tab) (2025), 26% of the more than 2,300 organisations it contacted have a CAIO, and 66% of the Chief AI Officers it surveyed expect most organisations to have one within two years. For UK SMEs with 10 to 250 employees, a fractional model closes the AI leadership gap without the headcount commitment. An AI advisor for business at this level covers strategy, supplier evaluation, team training and implementation oversight.

Our fractional CAIO service covers AI strategy, supplier evaluation, team training and implementation oversight. As an AI consultancy UK SMEs trust, we ensure every engagement is proportionate to your size, budget and ambition. Some organisations use the term virtual CAIO. The model is the same: senior AI leadership embedded in your business on a flexible basis.

A fractional Chief AI Officer from Hartz AI gives a UK SME senior AI leadership from £4,000 per month + VAT, without a full-time executive salary.

A fractional CAIO provides the leadership, but the first deliverable is usually a strategy and roadmap that gives the board clarity on where AI fits.

AI Readiness Audit Strategic AI Roadmap Fractional CAIO

How does AI strategy consulting turn ambition into a roadmap?

An AI strategy consultant helps your leadership team move from ‘we should do something with AI’ to a prioritised AI roadmap for business growth with timelines, resource requirements and expected returns for each initiative. The roadmap sequences projects by impact and complexity so your organisation invests in the right order.

The process starts with a readiness assessment that evaluates your current capabilities, data quality, team skills and risk profile. From there, we identify two to three high-impact AI opportunities and build a phased implementation plan your board can approve with confidence. The right AI strategy consultant UK organisations need is one who understands local regulatory requirements, funding opportunities and the practical constraints of SMEs.

In McKinsey's global survey The state of AI in 2026 (opens in a new tab), nearly nine in ten respondents report regular use of AI in at least one business function, yet only 37% attribute at least some EBIT impact to AI use. Using AI is now common; seeing it in the bottom line is not. That gap is what a roadmap is for, which is why we map how your work is done before we recommend any tool.

In our experience, for UK SMEs the gap between having ambition and having a plan is where most value is lost. A structured approach to strategy consulting closes that gap. For teams who need to build AI fluency before shaping strategy, our AI training workshops provide the foundational understanding that makes strategic conversations more productive. Once the roadmap is clear, the next question every board asks is: what does this actually cost, and what return should we expect?

Where our numbers come from

What does AI consultancy actually cost UK SMEs?

Hartz AI publishes fixed fees for AI consultancy, starting with an AI readiness audit from £5,000 + VAT, because opaque pricing wastes an SME's time. An organisation-wide audit is from £8,500 + VAT and a Strategic AI Roadmap from £7,500 + VAT. Audit and roadmap together are from £10,000 + VAT.

Retained AI leadership starts at £2,500 per month + VAT for an AI Advisor and £4,000 per month + VAT for a fractional Chief AI Officer, a fraction of the cost of a full-time executive hire. AI consulting for SMEs works best when every pound invested ties directly to a measurable business outcome.

The University of St Andrews Business School (opens in a new tab) (2025) found productivity gains of 27–133% for UK SMEs adopting AI, compared with non-adopters, with the benefits varying by sector. We help you build a business case your board can approve, tying every recommendation to specific outcomes like time saved, cost avoided, revenue opportunity or risk reduced. With costs understood, the practical question becomes whether your organisation is ready to act, and that starts with a structured readiness assessment.

Discuss pricing for your organisation

How do you assess whether your business is ready for AI?

An AI readiness assessment evaluates your organisation across five dimensions: data quality, team capability, process maturity, technology infrastructure and leadership alignment. The result is a clear picture of where you stand today and what needs to change before AI can deliver measurable value. An artificial intelligence consultant UK organisations trust will ground this assessment in your specific context, not generic frameworks.

Few businesses have gone deep with AI yet. Among UK businesses with 10 or more employees that use AI, only 10% use it extensively, according to the ONS (July 2026) (opens in a new tab).

In our experience, the SMEs that get real value from AI are the ones that assess where they stand before they buy tools. Our AI audit evaluates 40+ processes across your organisation to surface genuine risks, gaps and opportunities, not theoretical ones.

Most SMEs we work with discover they are more ready than they think in some areas and less ready in others. An AI maturity assessment removes guesswork: you get a prioritised list of actions ranked by impact and effort, a practical digital transformation roadmap, not a theoretical one. For organisations that need hands-on implementation after the assessment, our AI implementation services turn roadmap priorities into working systems.

For SMEs weighing their options, the choice of consultancy partner matters as much as the methodology, which raises the question of whether a boutique firm or a Big Four consultancy is the right fit.

Where our numbers come from

Why do UK SMEs choose boutique AI consultancies over the Big Four?

In our experience, enterprise consultancy frameworks rarely fit an organisation where the managing director also handles procurement. If you need an AI consultant for small business, a boutique firm delivers proportionate advice at proportionate cost.

Among AI consulting firms in the UK, boutique consultancies like Hartz AI offer three advantages for SMEs: proportionate pricing, direct access to senior independent consultants (not graduate analysts) and recommendations that are tool-agnostic rather than locked to a supplier's partner ecosystem.

In our experience, most SMEs do best with a small in-house AI lead, backed by outside expertise when they need it. For SMEs, a boutique consultancy provides that outside layer without the overhead of a Big Four retainer. If you are still weighing up firms, our guide to choosing an AI consultant for your SME sets out the questions to ask before you sign anything.

Not sure if you need consultancy or training?

If your team needs to build AI fluency before making strategic decisions, training is usually the right starting point. Many organisations combine both - training first, then consultancy to shape the plan.

Common questions

Common Questions About AI Consultancy with Hartz AI

AI consultant rates vary by seniority and engagement type. Hartz AI charges fixed fees instead. A scoped AI readiness audit is from £5,000 + VAT for an SME with 10 to 250 employees, rising to from £8,500 + VAT organisation-wide and from £10,000 + VAT where the environment is complex or regulated. A Strategic AI Roadmap is from £7,500 + VAT, or from £10,000 + VAT bought with the audit. Retained leadership runs £2,500 per month + VAT for an AI Advisor, £4,000 per month + VAT for a fractional Chief AI Officer and £6,000 per month + VAT embedded. We publish pricing because opaque fees waste your time and ours. The right consultant for you should be transparent from the first call.

For most UK SMEs, the answer is both, in sequence. In our experience, a consultant accelerates strategy and supplier evaluation in the first six to twelve months: areas where mistakes are expensive and senior expertise is scarce. After that, you want internal capability owning day-to-day AI decisions. We typically recommend a structured handover: consultancy embeds frameworks and trains your team, then transitions to a fractional advisory or ad-hoc support model.

An AI maturity assessment scores your organisation across five dimensions - data quality, team capability, process maturity, technology infrastructure and leadership alignment - to show where you are ready for AI and where you are not. The output is a prioritised list of actions ranked by impact and effort. It is the foundation of any credible AI roadmap and the first step we recommend for SMEs starting a structured engagement.
