The short version: Before you sign anything, ask an AI consultant to show you a past project’s actual output, name the tools they’ll use by brand, and put the price in writing tied to deliverables, not hours or “AI transformation.” If they get vague, dodge the question, or answer with a buzzword salad, walk. Most contract regret in this industry traces back to a question the client never asked out loud.
Why this list exists (and what it cost someone to learn it the hard way)
A client of mine, a Manchester based recruitment firm with 14 staff, signed a £15,000 contract in early 2025 with an “AI consultant” who promised to build them a custom candidate-matching system. Six weeks in, they had a Zapier flow connecting a spreadsheet to ChatGPT’s API and a PDF report calling it a “bespoke AI recruitment engine.” The consultant had subcontracted the build to someone in another country for a fraction of the fee and pocketed the rest for “strategy.” Nothing was technically wrong; the flow worked, sort of. But it was a £400 job dressed up as a £15,000 one, and the contract had no clause letting them claw money back once they worked that out.
That story is not rare. I hear a version of it every month. The fix is not complicated. It is a short list of questions, asked before you sign, not after the invoice lands.
The questions that matter most (ask these before you talk price)
- “Can I see the actual output from your last three clients?” Not a case study slide, the real thing: the dashboard, the report, the chatbot transcript. If they can only show you a testimonial quote, that is a red flag, not proof.
- “Which tools will you use, by name?” A consultant who says “we’ll use a proprietary AI framework” is often reselling ChatGPT, Claude, or Zapier with a markup. That is not automatically bad, but you deserve to know it, because you can buy those tools directly for £20 to £200 a month if that is all you need.
- “Who is doing the hands-on work, you or someone else?” This is the question people skip, and it is the one that would have saved my recruitment client £14,600. Plenty of consultants sell the strategy call and quietly hand the build to a junior contractor or an overseas team. There is nothing wrong with subcontracting if it is disclosed and priced fairly. It is a problem when the fee reflects the seller’s reputation and the work reflects a stranger’s Tuesday afternoon.
- “What happens if this doesn’t work?” Ask for a specific answer, not “we’ll iterate.” Get a defined number of revision rounds, a defined refund trigger, or a defined exit point written into the agreement.
- “What data of mine will you need, and where does it go?” If they need access to your customer list, your email account, or your CRM, ask exactly what happens to that data after the project ends. Get it in writing that they delete or return it.
- “What’s the fee if I want to leave after phase one?” Good consultants price in phases so you can exit cleanly. If leaving early costs you the full contract value, that is a sign the deal was structured for their protection, not yours.
Questions specifically about scope and skill
Anyone can call themselves an AI consultant right now. There is no licence, no professional body, no exam. That is not a criticism of the field, it is just the current reality, and it means the burden of vetting sits entirely with you. So push on skill directly rather than trusting the title.
Ask these questions of anyone, including me; the Glasgow page shows how I answer them for businesses in Glasgow.
- “What did you do before AI consulting became a job title?” A background in data engineering, marketing operations, or software development tells you something real. A background of “I ran a course on prompt engineering since March” tells you something too.
- “Show me a project where the AI approach didn’t work and what you did instead.” Anyone confident in their answer to this has real experience. Anyone who insists AI always works is either new to this or not being straight with you.
- “How will you measure whether this project succeeded?” Push for a number: hours saved per week, leads captured per month, response time cut from X to Y. If they answer with “increased efficiency,” ask again.
- “What’s the smallest version of this that would still be worth doing?” Good consultants will happily scope down. Ones who need the big contract to make sense of their fee will resist this question, which tells you something on its own.
Questions about the money (say these out loud, in this order)
Pricing across the industry is a mess right now, which I have written about in detail in how much an AI consultant costs a small business, but the short version is that day rates run from around £400 to £2,500 in the UK depending on seniority and whether they are freelance or attached to a larger firm. Ask these three, in order, before you discuss the total:
- “Is this priced by deliverable, by day, or by retainer?”
- “What’s included in that price, and what counts as a change request that costs extra?”
- “Can you break the total down by task, so I can see what each piece costs?”
If the answer to the third one is a flat refusal, that is worth noting. A vague total protects the seller. An itemised one protects you.
What the contract itself needs to say
The questions above are wasted if the answers never make it into the paperwork. A verbal promise about data deletion or revision rounds is worth nothing once there is a dispute. I have covered the specific clauses that matter in what an independent contractor agreement should always include, but for an AI project specifically, make sure the contract states, in plain writing:
- Who owns the finished system, prompts, workflows, and any data used to train or fine-tune it.
- What “done” looks like, described in a way you could hand to a stranger and have them agree it was met.
- A named point of contact who will do the work, not just sell it.
- A cancellation clause with a specific number attached, not “reasonable notice.”
- What happens to your data and accounts once the contract ends.
None of this is exotic legal language. It is the same due diligence you would apply to any contractor, and if a consultant treats these requests as insulting or unusual, that tells you something about how they have handled disputes before.
A short step-by-step for the actual meeting
When you get on the call, run it like this:
- Ask them to walk you through one real past project, start to finish, before any pitch about you.
- Ask the ownership and data questions while the mood is still relaxed, not at the end when you both want to wrap up.
- Ask for the price broken down by task, and write down their answer word for word.
- Ask what they’d do differently if the budget were half the size. Their answer tells you what they think matters.
- Tell them you’ll send questions back over email so the answers exist in writing, and watch how quickly and specifically they reply.
That last step matters more than people think. A consultant who answers a follow-up email within a day, with specifics, is showing you how they’ll behave mid-project when something goes sideways. One who goes quiet or sends a one-line reply is showing you that too.
The uncomfortable bit nobody puts in the pitch deck
Here is the part most guides on this topic leave out: a decent chunk of what gets sold as “AI consulting” right now is a markup on tools you could set up yourself in an afternoon for the cost of a monthly subscription. That does not make every consultant a con artist. Plenty of them are worth the fee, because they save you the weeks of trial and error, the wrong tool choice, and the workflow that quietly breaks every time your CRM updates. But the fee should reflect that judgement and time, not a made-up scarcity around “AI expertise” that any curious business owner could pick up with a few evenings of reading and testing. Ask yourself, honestly, whether you’re paying for expertise or paying for the word “AI” in the invoice.
This matters more if you’re comparing consultants who work with firms rather than solo. If you’re weighing up an agency, the same scrutiny applies, and it’s worth reading how one client approached hiring an AI consulting firm in Brisbane and what they wished they’d asked sooner, or how someone vetted an AI consultant in Sydney without getting burned by a reseller, because the reseller pattern shows up everywhere, not just in one city or one price bracket.
If you’d rather have someone sit with you through this whole vetting process rather than doing it alone from a list of questions, that is a fair reason to bring in an AI implementation coach for the first project, purely to sit on your side of the table while the contract gets negotiated.
Red flags that mean stop, regardless of how good the pitch sounds
- They cannot name a single client who would speak to you directly.
- The proposal uses the word “transformation” more than twice and no numbers at all.
- They want the full fee upfront with no phased payment tied to milestones.
- They get defensive rather than specific when you ask who does the actual build work.
- The contract has no exit clause, or the exit clause costs more than finishing the project would.
Frequently asked questions
What’s the single most important question to ask an AI consultant before signing?
Ask who will do the hands-on work, by name, and whether that person will be on the calls with you. This exposes subcontracting arrangements that inflate cost without adding value, which is the single most common source of contract regret in this field.
Should I be worried if an AI consultant can’t show me past client work?
Yes, treat it as a serious warning sign. A genuine track record includes actual outputs like reports, dashboards, or working automations, not just testimonial quotes, and any consultant with real experience will have something concrete to show you within minutes of asking.
How much should an AI consultant cost for a small business project?
UK day rates typically run from around £400 to £2,500 depending on seniority and whether they work solo or through a firm, and pricing should be broken down by task rather than handed to you as a single vague total.
What should an AI consulting contract include that people usually forget?
A clear statement of who owns the finished system and any data used to build it, a defined cancellation clause with an actual number attached, and a description of “done” specific enough that a stranger could check whether it was met.
