AI Consultancy UK: The Four Tiers, and What Each One Charges

Accenture publishes its day rates. Not in a brochure, but on the government’s own Digital Marketplace, because selling to the public sector obliges suppliers to file a rate card. The current version runs from £190 a day at the bottom up to £1,800 for the grade it calls Set strategy, inspire, mobilise. You can download the PDF this afternoon without speaking to anybody.

I keep going back to that document because it is the only honest thing on this subject you can read for free. Search this term and you get a league table of McKinsey and Deloitte, a directory that charges those firms for the listing, an agency landing page with a calendar link where the price should be, and a dozen pricing guides that contradict each other by a factor of ten.

So here is the map instead. Four tiers of supplier sell AI consultancy in this country. They charge very different money for work that overlaps more than any of them will admit, and two of the four are wrong for almost every business reading this. I sell in the smallest tier, so weigh what follows accordingly. Every number below points at a source you can check yourself.

What does an AI consultancy in the UK charge?

Somewhere between £575 and £1,800 a day, and which end you land on is decided by who you ring rather than by what gets built.

ITJobsWatch puts the median UK contract day rate for an AI consultant at £575 in the six months to 31 August 2026, drawn from 73 quoted rates. That is the market clearing price for a competent individual, and I have taken that figure apart to show how a quote gets assembled on top of a day rate. Accenture’s card tops out at £1,800 for its most senior grade. Boutique UK AI consultancies that bother to publish numbers tend to advertise somewhere around £950 to £1,500.

Now add VAT. Every figure quoted to you is exclusive of it, and if your taxable turnover sits under the £90,000 registration threshold you cannot reclaim a penny of the 20 percent. On a £12,000 pilot that is £2,400 of pure cost that never appeared in the proposal.

Who sells AI consultancy in this country?

Four distinct kinds of business, and the label on the website tells you almost nothing about which one you are talking to.

The global firms and integrators. Accenture, Deloitte, PwC, IBM, CGI. They sell programmes rather than projects, they staff those programmes with a pyramid, and their real customer is a company large enough to have a transformation budget. Their public sector rate cards are genuinely useful to you even though you will never hire them, because they are the only large supplier prices in Britain published under obligation rather than for marketing.

The mid market technology and data consultancies. Often the firm that already looks after your Microsoft 365 tenancy or your Salesforce instance, now with an AI practice attached. The advantage is real: they already know where your data lives. The risk is that AI arrives as an upsell on the estate they maintain, so the recommendation tends to be whatever their existing partnership sells.

The boutique AI consultancies. Between five and thirty people, usually founded in the past three years, often genuinely good. They sell in a ladder. A readiness sprint from a few thousand pounds, then a discovery and pilot phase in the tens of thousands, then a build. The honest ones will tell you when to stop climbing. The rest will keep selling you the next rung.

The solo specialists and small automation shops. One person or a handful, no pyramid, no discovery phase billed as a deliverable. Many trade under the automation agency label, so it is worth knowing what that label actually covers before you ring one. This is where the £575 median sits. The obvious weakness is capacity. The obvious strength is that the person who sold you the work is the person doing it.

Which tier fits a business your size?

Almost certainly one of the bottom two, and the adoption data explains why the market keeps pitching you the top two anyway.

The Office for National Statistics published AI adoption figures on 20 July 2026 showing 28 percent of UK businesses with fewer than ten employees using at least one AI technology, against 49 percent of businesses with 250 or more. The largest firms adopt at nearly twice the rate of the smallest.

That gap is what the marketing is calibrated to. Programme language, twelve week discovery phases, change management workstreams: all of it was built for the 49 percent, then pointed at everyone. When a boutique quotes you £35,000 for a discovery and pilot, it is not overcharging in the abstract. It is quoting a company with a hundred staff, and you happen to have eleven.

Here is the test I would apply. If you can name the task you want gone, in one sentence, without using the word strategy, you are in solo specialist territory and you should not be paying for discovery. If you genuinely cannot name it, that is a real problem, but it is a cheap problem to solve. Our AI Opportunity Scorecard takes about two minutes and gets most owners to a named task without an invoice.

Can the government pay for part of it?

Yes, and the two most accessible schemes are unglamorous enough that almost nobody selling AI consultancy mentions them.

Made Smarter Adoption is for English manufacturers with 10 to 249 employees. It offers match funding of up to 50 percent of a project cost, capped at £20,000, and it now covers technical advice and training rather than only machinery. Regional delivery and deadlines vary, so start with your region’s adviser rather than a national form.

Help to Grow: Management is broader. Any UK business employing 5 to 249 people can send a senior decision maker on a 12 week, 50 hour programme for £750, with the remaining 90 percent covered by government. It is not an AI course. It is the strategic thinking half of what a consultancy sells you, at roughly one day of a boutique’s rate.

Who owns what the consultancy builds?

Not you, unless somebody wrote it down. This is the single most expensive thing UK buyers get wrong, and it costs nothing to fix before you sign.

Paying an invoice does not transfer intellectual property under English law. Absent a written assignment, the supplier who created the work generally owns it. Consultancies also reserve their background IP, meaning the templates and methods they brought with them, which is fair enough right up until the boundary between background and foreground quietly swallows everything they built for you.

So name the artefacts in the contract. The prompt files. The Make or n8n scenario exports. The scripts. The written documentation. The credentials and the account ownership, which people forget until the day the automation breaks and it turns out the API key lives in someone else’s login.

A supplier who will assign all of that without a fuss is selling you a system. One who resists is selling you a subscription and calling it a project.

Do the UK rules mean you need a consultancy?

Rarely, and less often than the compliance led sales pitch implies. There is no UK AI Act. Britain chose to regulate AI through its existing regulators rather than a single statute, so the law that governs your AI is mostly the law that already governed your sector.

Where personal data is involved, UK GDPR and the Data Protection Act 2018 apply exactly as they always have. The Data (Use and Access) Act 2025 adjusted the rules on automated decision making, and if you are planning anything that decides something about a person without a human involved, the ICO’s guidance is the thing to read before a consultancy’s white paper.

The EU AI Act is a separate question, and it can reach a British company whose AI outputs are used inside the EU. Its implementation timetable has shifted more than once, so check the current position rather than a dated summary.

None of that requires a retainer. It requires somebody in your business reading two pages of regulator guidance. Where a specialist genuinely earns the fee is in regulated sectors and in anything making decisions about people, where a data protection impact assessment is not optional and the cost of getting it wrong dwarfs the day rate.

What could you build yourself before ringing anyone?

The first automation, in most cases, for less than the cost of lunch. This is the part the tier ladder is designed to skip past.

Claude Pro is $20 a month and includes Claude Code, which works on real files on your own machine rather than in a chat window. Make starts at $9 a month with a usable free tier. Zapier gives you 100 free tasks a month. Power Automate Premium is £11.50 per user per month paid yearly, excluding VAT, and if you already pay Microsoft it may be the shortest path. n8n costs nothing if you host it yourself.

Pick one job you already understand completely. Not the important one. The annoying one, the twenty minutes that vanish every time a supplier invoice arrives. Build that, then fix it when it breaks. You will learn more about where AI genuinely helps your business than any readiness sprint will tell you, and you will be able to read a consultancy’s proposal properly afterwards. The questions those sprints ask are not secret either, so you can work through the readiness check yourself first.

That is the whole wedge, and I will state it plainly since it costs me money to say: most owners should learn to build the simple half themselves and buy only the hard half. More about why I work that way.

So who should you actually ring?

If I ran a business under fifty people, I would not ring the top two tiers at all. I would spend a fortnight building something small and slightly rubbish myself, because that fortnight turns you from someone who can be sold anything into someone who can read a quote. Then I would hire one person, for a named job, on a fixed price, with an IP assignment clause I had actually read.

The uncomfortable part is that a good chunk of what the market sells as AI consultancy is discovery you could do yourself and building that has quietly become easy. The part that holds its value is judgement about what not to build, and the regulated work where a mistake is expensive. That is a much smaller purchase than the ladder implies, and it is meant to be.

If you want the short version of that judgement applied to your business, my AI Opportunity Audit is a £500 fixed fee session where we go through your processes, find the highest impact place to put automation, build one live in Claude Code, and you leave with a prioritised roadmap. There is a free 15 minute intro call first, and I will tell you on that call if the honest answer is that you do not need me yet.
