Best AI consultancies in the UK for mid-market firms

There are more UK AI consultancies than there were UK AI projects a few years ago, and their homepages promise the same things in the same words. The differences that decide whether an engagement works sit elsewhere: who does the work, what it costs to find out whether the idea is any good, whether the certificate in the footer covers the team on your project, and what happens once the system is live.

This page covers ten UK AI consultancies a mid-market buyer is likely to shortlist, what each firm publishes about its own work and prices, and where each fits best. Several of them compete with us directly.

On published prices alone the market has a visible shape. Entry diagnostics, the piece of work that tells you where AI fits before you commit to a build, run from £3,500 to £15,000 across the firms below that publish one. Published day rates run from £950 to £2,400 depending on seniority, and ongoing part-time AI leadership, sold as a fractional Chief AI Officer or an embedded team, runs from £3,000 to £8,500 a month. Half the firms on this page publish no prices at all. With them, the first number you hear arrives on the sales call.

How we put this list together

OpenKit wrote this page and OpenKit is one of the ten, so read it as our reading of the market rather than an independent ranking. Our own entry comes first because this is our site; the other nine follow in alphabetical order. Every entry is built from what the firm publishes about itself, read on its own website on 31 August 2026, and the references at the end link to the pages we read. Nobody paid to be included, and where we could not confirm something the entry says so.

OpenKit

Most of our engagements open with the AI Audit and Transformation, a fixed-scope, fixed-fee piece of work from £10,000 that lands within four weeks and produces a written report and a prioritised 12 month roadmap. OpenKit becomes your business’s embedded AI team: the people who ran your audit stay on to deliver it. That follow-on is the Embedded AI Lead, from £5,000 a month, and both floors sit on our pricing page rather than behind a call.

The work we can name is in the portfolio. For FW Thorpe’s Thorlux Lighting we validated proof-of-concept queries against roughly 6.5 million occupancy records. The Stow Brothers engagement mapped five admin workflows against a measured 172 hours a month, and an EMQN discovery sprint tested AI marking at 93 to 96% per-criterion accuracy across six languages. We hold ISO 27001 and ISO 9001, both since November 2024, along with Cyber Essentials, and we operate to UK GDPR.

The fit is an organisation that needs to know where AI belongs in its operations before committing to a build, and that has to satisfy a compliance or procurement review on the way. We are not a staff augmentation shop, so if you want three contract engineers by the day there are better routes, and a group-wide transformation at FTSE scale belongs with a firm many times our size.

&above

&above is a London AI product studio formed when the design agency RCCO merged with the film studio WILD, and it treats AI as product craft rather than a consulting discipline.¹¹ It is a Google partner, and its founder has described building AI products for Google and Tesco in interviews with Consultancy.uk.¹² It publishes no prices and no security certifications.

It is here as the other kind of supplier: if the thing you want is a customer-facing product where design quality carries the value, a studio may serve you better than a consultancy.

AI Expert UK

AI Expert UK works with small and mid-sized firms from Worcester, and its entry point is the cheapest on this page: a free two-minute AI readiness assessment, followed by a workshop and a roadmap, then implementation.⁷ It lists AI compliance and EU AI Act readiness among its services, and carries testimonials from Scimitar Sports, Build Group and Hayward-Wright Accounts. It publishes no prices and no certifications.

It suits a smaller firm that wants a cheap answer to whether AI is worth its time and does not face a formal procurement review at the end.

Aiimi

Aiimi is a Milton Keynes data and AI firm built for large organisations, and it says so plainly: its customer descriptions run to national security, critical infrastructure and government.⁴ Its depth is in the unglamorous half of the work, getting an organisation’s data governed and findable before anything intelligent is built on top, and its published certifications are the strongest on this page, ISO 27001 and Cyber Essentials Plus, with carbon neutral certification alongside. It publishes no prices.

A mid-market buyer should expect an enterprise methodology and enterprise process. The fit is the upper end of the mid-market, where the data problem is bigger than the AI problem.

Boardman

Boardman sells fractional technology leadership, covering CTO, CIO, CISO and Chief AI Officer roles, to scaling businesses it defines as £2 million to £30 million in revenue and 10 to 100 people.⁸ Its AI work carries fixed published prices: an AI Ready Review at £7,500 over five days, an AI strategy at £22,000 and a full strategy with a 90 day plan at £35,000; ongoing fractional leadership is priced on consultation. It operates from Manchester, London and Edinburgh and publishes no certifications.

Choose Boardman if you are a founder-led business at the smaller end of this page’s range and need a senior head in the room more than a delivery team.

Fifty One Degrees

Fifty One Degrees is the firm here whose positioning most resembles ours, and it is direct about who it serves: mid-market businesses of £5 million to £250 million turnover, from offices in London and New York.¹ Its “Embed Over Advise” model states that the deliverable of every engagement is a production system in your environment, not a strategy deck, and it names clients with numbers attached, Heatable, Freddie’s Flowers, Resi and Panmure Liberum among them. It publishes partial pricing, with proofs of concept typically under £15,000 and Claude implementation packages from £25,000 to £70,000,² and no security certifications.

The fit is a mid-market firm that wants senior practitioners building inside its team from the first week and can carry supplier assurance in the contract rather than off a certificate.

Geeks Ltd

Geeks has been building software for 18 years by its own count, and pairs AI and data strategy with a full development shop that runs from opportunity discovery through model training and integration.⁵ It names easyJet, UK Parliament and Reed in Partnership among its clients, holds ISO 27001, and has a Queen’s Award for Enterprise in Innovation behind it.⁶ It publishes no prices; in their place it offers an automated scoping tool.

Geeks fits an organisation that wants one supplier from strategy through to a large build, with the paperwork to clear procurement on the way.

Insightful AI

Insightful AI is a governance-first consultancy in Warrington serving SMEs, charities and the public sector, and it is unusually open about money: training from £895, advisory at £1,200 a day, AI automation from £1,500 and custom software from £10,000.⁹ Its named work includes the National Crime Agency and the National Police Chiefs’ Council. It publishes no security certifications, though it is ICO registered.

The fit is a smaller organisation, or one spending charitable or public money, that needs governance settled before anything is built and a price it can see before the first call.

Intelance

Intelance is an advisory and assurance firm rather than a builder: it reviews and assures AI, cyber and data risk, and a system that needs building will need a second supplier.¹⁰ Within that scope it is the most price-transparent firm on this page, with fixed fees on every service page. Assurance reviews start at £4,500 plus VAT, an AI Governance QuickScan at £15,000 plus VAT and monthly advisory at £6,500 plus VAT, with day rates of £1,100 to £2,400. It is founder-led, holds Cyber Essentials Plus and IASME Cyber Assurance Level 2, and names the NHS, Rolls-Royce and the Welsh Government among its clients.

The fit is a board that needs independent assurance over AI it is already buying or building elsewhere.

The AI Consultancy

The AI Consultancy publishes its entire rate card, which no other delivery firm on this page does: a Readiness Sprint from £3,500, Discovery and Pilot from £15,000, Build and Embed from £40,000, day rates of £950 to £1,500, and fractional Chief AI Officer retainers from £3,000 to £8,500 a month.³ It is London-based, describes itself as an Anthropic Consulting Partner, and works heavily with professional services, covering law, accountancy, dental practices and logistics. It publishes no security certifications. Its site blocked our in-browser check, so those figures come from two automated reads in August 2026 that matched.

It fits an SME or scaleup that wants every price before the first conversation and is comfortable starting small.

Every certification in that column is what the firm displays on its own site. We have not seen the certificates or checked their scope with the issuing bodies, and you should not take ours on trust either: ask any supplier for the certificate and the scope statement that goes with it.

How to shortlist

Start from the decision you are buying. If you do not yet know where AI fits in your operations, buy the smallest piece of work that answers that question, which on this page costs between £3,500 and £15,000 depending on depth, and judge each firm on what its diagnostic commits to putting in writing. If you already know what you want built, weight named clients with numbers over logo walls and ask who will actually be doing the work. If what you need is oversight of AI you are already buying, the assurance and fractional firms here cost far less than a wrong build.

Then ask the boring questions. Ask for the certificate and the scope statement rather than the badge on the homepage, and ask where the people doing your work will sit. Ask too what happens after go-live: a system that reads accurately in March can drift by September, and somebody has to own that. Published prices and named numbers do not prove the work will be good, but they are the habits of a firm that expects to be checked.

If the question you are stuck on is where AI fits at all, that is what our AI audit answers, and our pricing page carries the same numbers this page quotes.
