Best AI Consultants in the UK (2026): Which Fits Your Stage

Every list like this has an author with an angle, and this one's mine. I sell AI implementation work to UK businesses, so I'm not neutral. Take my entry with a pinch of salt and judge the other six on what their own sites say. I'd rather you hire the right firm than hire me for the wrong job.

I haven't sorted these by region, size or price. I've sorted them by where you are with AI, because that's what decides who's worth a call. A firm that's brilliant at a two-year programme for a hospital trust is the wrong first phone call for a twelve-person accountancy practice that hasn't decided what AI is for yet.

Stage by stage: who fits

Your stage	Names to look at	The trade-off
Exploring: you want to know where AI is worth using	Blue Canvas, Hartz AI	You get a plan before anything is built, so results come later
One workflow or one platform, built and handed over	Bigrise, The AI Consultancy	Narrow by design; ask how they'd handle the next problem
Getting the whole team confident on the tools	Day Seven (Hartz AI also trains)	Built for groups, not a solo owner
A long programme in a large organisation	Faculty	Aimed at big organisations and public bodies
A small business that wants the work done alongside one person	Lilach Bullock (me)	One person, not a bench

Everything below about the six firms comes from their own websites, as of Nov 2026. Where a firm calls itself something, I've said so rather than repeated it as fact. I've left out every fee, headcount and client logo on purpose, because those change and you should hear them from the firm.

Exploring: is AI worth using here? Blue Canvas and Hartz AI

Blue Canvas

Blue Canvas calls itself an AI consultancy in Northern Ireland, based in Derry, working with small and medium businesses across Northern Ireland, Great Britain and the Republic of Ireland. Its site describes a clear order: find the jobs where AI is worth using, build and test the workflows, train the people who'll use them and, if you want, keep them running each month. The audit ends in a ranked written plan, which is exactly what a cautious owner needs before spending on a build.

It lists industry pages for accountants, estate agents, solicitors and construction, and says it builds across Microsoft 365 Copilot, ChatGPT, Claude, Codex and Power Automate, connected to the tools you already use. The trade-off is reach: it's a regional base, so if you want someone in your London office every week, ask how that works before you book.

Hartz AI

Hartz AI describes itself as London-based AI training, consultancy and implementation for UK SMEs. Its site says the consultancy and fractional Chief AI Officer services are for UK businesses with 10 to 250 employees, running from readiness audits to strategic roadmaps. It lists four pillars: training, consultancy, implementation and governance, with the governance work framed around UK GDPR, the EU AI Act and the UK's approach to AI regulation.

It fits a business that wants to learn first, map the options and then decide what to build. It's training-led, so if all you want is one custom system and no ongoing programme, ask how that's scoped. The real pro is the governance pillar: plenty of small firms skip that part and regret it later.

One workflow or one platform, built and handed over: Bigrise and The AI Consultancy

Bigrise

Bigrise calls itself an AI consultancy for UK small and medium businesses covering tools, training, workflows, agents and custom software. It says it's based in London and Northampton, works across the UK in person where it can and online as well. Its AI Working Sessions are a day working one to one on a specific problem, tool or workflow, and at the other end it lists custom builds for bigger problems.

What I like is the handover line: its site says that when an engagement finishes, the training material, the builds and the documentation are handed over. It also says it works with a small number of people, so ask about availability and who'll be doing the work.

The AI Consultancy

The AI Consultancy describes itself as London based, in Hoxton, working UK-wide, and says it specialises in deploying Claude across UK teams and organisations, while also working with ChatGPT and other large language models. It describes the Claude work as rollout and configuration across teams and enterprise accounts, including workspace setup, access controls and usage governance. It also offers on-site workshops and in-person strategy sessions for London businesses.

It suits a team that has already picked Claude and needs it set up safely. The trade-off is focus: if you haven't chosen a platform and want a tool-neutral view, ask how it handles that conversation.

Getting the whole team confident: Day Seven

Day Seven calls itself a UK-based AI partner offering training and consultancy. Its training is hands-on with ChatGPT, Microsoft Copilot, Claude and Gemini, built around a team's everyday work, with prompt engineering and workflow automation added in. Its site says it's for teams in UK organisations from six people, ideally ten or more, delivered at your offices or live online.

Alongside the training it lists AI strategy, adoption, agents for your own use cases and governance, plus a digital Academy of self-paced Claude and Microsoft 365 Copilot courses for organisations, by invitation. If you're a solo owner, you're not who it's built for, and that's fine. If your problem is ten people with licences and no habits, it's a sensible first call. Hartz AI's training pillar is worth comparing here too.

A long programme in a large organisation: Faculty

Faculty's address on its site is Old Street in London. Its about page says it was set up in 2014 because its founders thought AI would be the most important technology of our time, and it lists industries from energy and financial services to defence, education, public services, and health and care. The case studies on its home page include forecasting hospital demand for the NHS and improving network stability for NESO.

This is the end of the market where AI is a long, serious programme with data scientists involved. A small business shouldn't expect the same fit, and I'd skip it if you're still deciding whether AI is worth an afternoon. For a public body or a large company with a hard problem, it belongs on the shortlist. It also runs a Fellowship that helps academics retrain into commercial data science, which tells you where its talent comes from.

Doing the work alongside you: my own entry

I wrote this page and I've put myself on it, so read this part knowing that. I'm an AI implementation consultant and fractional CMO with 23 years in marketing, and I went all in on AI in 2024, rebuilding my consultancy around practical workflow work. I'm British and I work in English with clients worldwide, including UK small businesses, remotely and on UK hours. Clients have included Twitter, Dropbox, IBM, monday.com and Greenpeace, and I write a weekly newsletter that goes to 15,000 people.

My UK work is with owner-led businesses: finding the repeatable work that eats the week, building AI workflows inside the tools they already use, and leaving the team owning them. I've written more on what that looks like in my guide to choosing an AI consultant as a small UK business. The honest trade-off is the one from the table: I'm one person, not a bench, so if you need ten specialists next month, a firm above is the better fit.

Buying AI help without regret

The UK government has thought about this harder than most small firms have time to. The UK government's guidelines for AI procurement, published 8 June 2020, set out guiding principles on how to buy AI technology and the problems that can come up along the way. They were written for government departments buying AI, but the questions carry over to a business of any size.

Three of those questions are worth stealing. What problem are you buying for, in one sentence? What data will the work touch, and who's responsible for it? And how will you know, in plain numbers, whether it worked? A consultant who can't help you answer all three before a build is selling you a build, not a result. My longer guide to how to judge an AI consulting firm goes through the rest.

Narrowing it down to two

1. Name your stage honestly. Exploring, one build, a whole team or a long programme. Most businesses that think they're at stage two are at stage one.
2. Pick two names from that row of the table. Two is enough to compare. Five turns into a month of discovery calls.
3. Ask each for the receipts. One shipped piece of work like yours, with what it looked like before and after, and who did it.
4. Check the handover. Ask what you'll own when they leave: the workflows, the prompts, the documentation and the training.

My verdict: I'd shortlist two, ask each for one shipped piece of work with a before and after, and skip anyone who leads with a logo wall instead of a result. If you sell marketing services and want the wider field, my list of AI marketing consultants worth knowing covers the independents and agencies outside the UK too.

Where I sit

I'd be a hypocrite recommending AI work I don't do on my own business, so here's my receipt. Between January and September 2026, Google clicks to my site went from 1,322 a month to 6,412, and visits from AI assistants such as ChatGPT, Perplexity, Claude and Copilot went from 32 a month to 3,599. Those are my own Search Console and GA4 figures, and they're the reason I'm comfortable putting my name next to six firms with bigger teams.

That doesn't make me right for every business on this page. It makes me right for an owner who wants someone to roll their sleeves up on the first few workflows and get the business found in AI answers while they're at it.

If you're a UK small business at the exploring or first-build stage, that's where I can help. I run AI training and workshops for teams, and help businesses with AI enablement and workflow automation, so the busywork runs itself and people get time back. Most of that work is with SaaS marketing teams and small businesses. Here's how we can work together.

Frequently asked questions

Who are the best AI consultants in the UK?

I wrote this list and included myself, Lilach Bullock, so I'm not neutral. Sorted by stage, the names I'd look at are Blue Canvas and Hartz AI for exploring, Bigrise and The AI Consultancy for one workflow or platform built and handed over, Day Seven for getting a whole team confident, and Faculty for long programmes in large organisations.

Where do I start if I run a small UK business and have never used AI?

Start with a written plan, not a build. A consultant should look at how work moves through your business and rank the jobs where AI is worth using. Blue Canvas and Hartz AI both describe that kind of first step on their sites, and it's how I start with clients too.

Do I need an AI consultant based in London?

Not usually. Most of the work is done on screen, inside the tools you already use. Some firms, such as The AI Consultancy and Bigrise, say they offer in-person sessions in London, which helps if your team learns better in a room. Ask about it, but don't let postcode decide.

What should I ask an AI consultant before I sign?

Ask what problem you're buying for in one sentence, what data the work will touch and who's responsible for it, and how you'll measure whether it worked. The UK government's guidelines for AI procurement were written for public buyers, but those questions carry over to any business.

Should a small business hire a large firm, a boutique or an independent?

Match it to your stage. A large firm like Faculty suits long programmes in big organisations. A boutique suits a defined build or team training. An independent suits an owner who wants one person doing the work alongside them. Ask each for one shipped example before you decide.
