You want to add AI to your business — a chatbot, a document search tool, something that handles repetitive admin. But before you commit, you need to know what AI consultants actually charge. This page gives you honest UK numbers for 2026: day rates, hourly rates, what fixed-price projects cover, and how to tell whether you're being quoted fairly.
The short answer: in 2026, UK AI consultants charge £500–£1,500 per day, and a single fixed-price AI feature typically costs £750–£2,500. Where you land in that range depends mostly on who you hire:
| Who you hire | Day rate (2026) | Hourly equivalent |
|---|---|---|
| Freelance / independent AI consultant | £500–£750 | £75–£125 |
| Boutique AI consultancy (1–10 people) | £600–£900 | £100–£150 |
| Specialist AI firm | £900–£1,200 | £150–£200 |
| Big four / major tech consultancy | £1,000–£1,500+ | £200+ |
Location shifts these numbers too: London day rates typically run 20–40% above equivalent North West, Midlands, or Scotland rates for the same standard of work, because most AI development is done remotely anyway. If you're comparing quotes, compare the deliverable — not the postcode.
Most UK AI consultants price work one of two ways: a day rate (time and materials) or a fixed price per project. Which is better depends entirely on how clearly you can define what you want.
UK AI consultants typically charge £500–£1,500 per day, depending on experience and specialism. Large consultancies (the big four, major tech firms) charge more. Freelancers and boutique firms tend to sit in the £600–£900 range.
Day rates suit exploratory work — proof-of-concept builds, architecture reviews, or multi-phase projects where the scope will evolve. The risk is that without a defined scope, costs can expand quickly.
Some AI consultants also quote an hourly rate rather than a full day. As a rough guide, UK AI consultant hourly rates fall between £75 and £200 per hour — freelancers and independents typically £75–£125, specialist firms £150–£200+. An hourly rate is essentially a day rate divided down (a £750 day is roughly £100/hour), so the same warning applies: without a capped scope, hourly billing can drift. Hourly works best for small, well-bounded jobs — a code review, a short advisory call, or a quick fix — rather than building a whole feature. For anything larger, ask for a fixed price so the number can't move.
A fixed-price engagement defines the deliverable upfront — one feature, one sprint, a known result. You pay a set amount and know exactly what you're getting. This is better for most first AI projects because the scope can usually be defined clearly.
Fixed-price AI features in the UK typically run £750–£5,000, depending on complexity:
| Feature type | Typical UK cost | Timeframe |
|---|---|---|
| Document search (search PDFs, policies in plain English) | £750–£1,500 | 5–7 days |
| Internal AI assistant (staff Q&A over your knowledge base) | £750–£1,500 | 5–7 days |
| Customer enquiry triage / response drafting | £750–£1,200 | 5–7 days |
| Document analysis & data extraction (invoices, CVs, specs) | £750–£2,000 | 5–10 days |
| AI chatbot integrated into an existing web app | £1,500–£5,000 | 10–20 days |
| Full AI platform build (new product) | £10,000+ | Ongoing |
The biggest cost drivers are scope clarity, integration complexity, and the state of your existing system.
A well-defined brief ("I want staff to be able to search our 200-page policy manual by asking questions in plain English") is far easier to price than "we want to do something with AI." The clearer you can describe the specific workflow you want to improve, the more accurately any consultant can quote — and the less likely the project is to overrun.
Dropping an AI feature into an existing Next.js or React app is straightforward. Integrating with a legacy system that has no API, or that lives behind a complex internal network, adds cost. If your existing software is modern and has a reasonable codebase, integration is usually the smallest part of the work.
If you want the AI to search your documents, those documents need to be in a processable format. PDFs are fine. Scanned images without OCR are not. If your data is messy or poorly structured, budget for cleaning time before the AI feature itself.
An AI feature uses a model (OpenAI, Anthropic, Azure OpenAI) that charges per use. For most small business use cases — document search used by a small team, an internal assistant answering 50–100 questions a day — this is typically £10–£50/month. It's worth asking your consultant to estimate this before you commit.
If you're a small business rather than a funded startup or enterprise, the numbers above can look intimidating — but the practical entry point is much lower than most people expect. You do not need a big-consultancy engagement or a five-figure budget to get value from AI. A small business first project is usually a single, fixed-price feature in the £750–£1,500 range: one clearly defined problem, solved and integrated into software you already use.
The key to keeping small-business AI consulting affordable is scope discipline. Pick one workflow that costs you real time — searching documents, drafting the same customer replies, extracting data from invoices — and solve just that. Avoid open-ended "AI strategy" engagements, which are priced for organisations with budgets to match. A good consultant working with small businesses should be comfortable starting small, quoting a fixed price, and letting the first feature prove its value before you spend more.
Whether you're paying a day rate or a fixed price, a legitimate AI consulting engagement should include:
What it should not include: endless discovery workshops before anything is built, strategy decks that don't produce working software, or vague "AI readiness assessments" that aren't leading somewhere specific.
That depends on what problem you're solving. The clearest cases for a positive return are:
If the problem you're describing can be put in those terms, a first AI feature at £750–£1,500 will almost certainly pay back within a few months. If you can't point to a specific workflow that will improve, it's worth slowing down and clarifying the problem before spending anything.
In 2026, UK AI consultants charge £500–£1,500 per day. Freelancers and independents typically charge £500–£750/day, boutique specialist firms £600–£900/day, and large consultancies £1,000–£1,500+/day. Fixed-price projects for a single AI feature run £750–£2,500.
Around £700–£900. Freelancers sit at £500–£750, boutique firms £600–£900, and big-four or major tech consultancies £1,000–£1,500+. London rates run 20–40% above North West and Scotland rates for equivalent work.
For a well-defined first feature, yes — you know the cost upfront and the scope is locked. Day rates suit exploratory or multi-phase work where scope genuinely can't be fixed in advance.
Document search, customer enquiry triage, simple internal assistants, and document data extraction can all be delivered as a single focused feature for £750–£1,000 if the scope is clear and you have an existing system to integrate into.
Roughly £75–£200 per hour. Freelancers and independents usually sit at £75–£125; specialist firms charge £150–£200+. For anything bigger than a short advisory job, ask for a fixed price instead — it caps the total so the cost can't drift.
A first small-business AI feature is typically £750–£1,500 fixed-price: one clearly defined workflow solved and integrated into software you already use. You don't need an enterprise budget — start with one feature, prove the value, then expand.
No. Most AI development work is done remotely. There are good consultants across the UK — London day rates (often £900–£1,500) are not necessarily better than North West or national rates. What matters is the quality of the work and the clarity of the engagement. For region-specific numbers, see what AI consultants cost in London and AI consulting rates in Scotland.
Mainly the AI model API fees (typically £10–£50/month for small team use) and any hosting costs. A good consultant will give you an estimate of these before the project starts so there are no surprises.
A fair quote matches the scope. If you've described one specific feature and the quote comes back with three phases of discovery workshops before anything is built, that's a warning sign. Look for clear deliverables, a defined timeline, and a payment structure that ties to delivery milestones.
