AI consulting in the UK costs roughly £500–£2,000 a day for independent consultants, £900–£1,600 for mid-tier firms, and £2,000–£5,000 for Big 4 and strategy houses — where programme minimums start around £100,000. Fixed-scope work runs from about £3,500 for a readiness audit to £45,000+ for a quarter-long transformation programme. This is the pricing companion to our honest comparison of the best AI consulting firms in London and the UK — here we cover only the money.
Key Takeaways
- Day rates cluster in three bands: independents £500–£2,000, mid-tier consultancies £900–£1,600, large firms and strategy houses £2,000–£5,000 per consultant per day.
- The rate matters less than the multiplication: a Big 4 squad of six for a quarter is a £500,000 conversation even at mid-band rates. Always price the team-week, not the day.
- Fixed-scope benchmarks: readiness audits £3,500–£15,000, strategy sprints £12,000–£40,000, quarter-long adoption programmes £45,000–£250,000, custom builds mid five figures to seven figures.
- Very few UK AI consultancies publish prices. We do — £3,500 audit, £12,000 two-week sprint, £45,000 90-day programme, net of VAT — and we think the market would be healthier if everyone did.
- The most expensive engagement is the one that changes nothing: over 60% of UK businesses cite skills, not cost, as their main AI barrier, so budget for enablement or expect shelfware.
How AI consultants charge in the UK
Two models dominate. Time and materials: you pay per consultant per day, the norm for large firms and staff augmentation. Fixed scope: you pay for a defined outcome — an audit, a strategy sprint, a training programme — the norm for boutiques. Neither is inherently better. Time and materials flexes with messy, open-ended work; fixed scope transfers overrun risk to the vendor and makes comparison shopping possible. What matters is knowing which one you're being quoted, because a seductive day rate hides total cost, and a chunky fixed fee can still be the cheaper option.
AI consultant day rates in London and the UK (2026)
| Tier | Day rate (per consultant) | Typical engagement shape | Watch out for |
|---|---|---|---|
| Independent consultants / contractors | £500–£2,000 | Advisory days, fractional AI lead, niche expertise | Quality varies wildly; one person can't run org-wide change |
| Boutique & mid-tier firms | £900–£1,600 | Fixed-scope audits, sprints, adoption programmes | Check who delivers — partner-led sales, junior delivery exists here too |
| Large SIs, Big 4, strategy houses | £2,000–£5,000 | Multi-month programmes, teams of 4–10+ | £100k+ practical minimums; layers between you and the seniors |
These bands are compiled from published G-Cloud rate cards, framework pricing and the quotes clients share with us when comparing proposals — they're consistent with what the UK government's Digital Marketplace has made visible for years. London carries a modest premium over the rest of the UK, mostly at the top tier.
"Clients fixate on the day rate, but the day rate is the least informative number in the proposal. Six people at £1,800 for twelve weeks is £648,000. One senior practitioner at £1,500 for ten days is £15,000. The question is never 'what's your rate' — it's 'what does the outcome cost, and who exactly is producing it'."

What AI consulting projects cost by engagement type
| Engagement | Typical UK range (2026) | Duration |
|---|---|---|
| AI readiness audit / opportunity assessment | £3,500–£15,000 (Big 4 versions: £50,000+) | 1–3 weeks |
| AI strategy sprint (charter, governance, roadmap) | £12,000–£40,000 | 2–4 weeks |
| Adoption / transformation programme with training | £45,000–£250,000 | One quarter+ |
| Custom AI build (models, agents, data platforms) | £50,000–£1m+ | 3–12 months |
| Enterprise integration programme (Copilot, ChatGPT Enterprise at scale) | £100,000–£1m+ | 6–18 months |
The bands are wide because scope is elastic: an audit covering one business unit is not an audit covering nine markets. What should never be elastic is what the number buys — a full breakdown of what belongs inside an audit is in our AI readiness audit guide, and training-only budgets are covered in the UK AI training price guide.
Our prices, published
Transparency claim, receipts attached. Spicy Advisory's UK engagements are fixed-scope and public: £3,500 for a readiness audit and executive briefing, £12,000 for a two-week AI strategy sprint (charter, governance aligned to UK GDPR and ICO guidance, 30/60/90-day roadmap), and from £45,000 for a 30/60/90-day transformation programme with workflow-first training throughout. All net of VAT. SME and mid-market engagements start at the same £3,500. If a competitor's proposal is vaguer than this page, that's information too.
What actually drives the price up or down
- Seniority of who shows up. A partner who sells and a bench that delivers is the classic model; founder-led firms invert it. Ask for named people and their rates.
- Team size × duration. The multiplier that turns rates into six figures. Challenge headcount before challenging the rate.
- Scope of estate. Number of business units, markets, languages and systems in play.
- Governance load. Regulated sectors add model risk, audit trails and sign-off cycles — real work, legitimately priced. Our financial services guide covers what that premium buys.
- What's left behind. Enablement and training are sometimes stripped out to make a quote look lean. That's the line item that determines whether anything sticks — over 60% of UK businesses cite the skills gap as their main AI barrier, ahead of cost (British Chambers of Commerce; collected in our UK SME AI statistics).
How to compare AI consulting quotes like-for-like
- Normalise to outcome cost. Convert every proposal to "total fee → named deliverables → date". Ignore rates until this is done.
- Extract the people. Named individuals, their seniority, and their percentage allocation. "A team of experts" is not an answer.
- Find the enablement line. If training and adoption aren't itemised, ask why. A £200,000 build with no enablement usually loses to a £60,000 build with it.
- Check the overrun clause. Fixed scope: what triggers a change order? Time and materials: what's the cap?
- Apply the day-90 test. Ask what your teams will do differently ninety days after the engagement ends, and how it will be measured. The ten harder questions are in how to choose an AI consultancy.
"We publish our prices because the alternative — 'it depends, let's scope it' — quietly costs UK buyers months. You can disqualify us in thirty seconds if the budget doesn't fit. That's a feature. The firms that make you sit through three meetings to hear a number are charging you for those meetings somewhere."
— Toni Dos Santos, Co-Founder, Spicy Advisory
Budget rule of thumb for a 50–1,000 person company: reserve roughly a third of your first-year AI budget for people (strategy, governance, training) rather than technology. A £3,500 audit that stops a £150,000 misdirected build is the best-performing line in the budget.
Frequently asked questions
How much does an AI strategy sprint cost in the UK?
Between £12,000 and £40,000 for a two-to-four-week fixed-scope sprint producing an AI charter, a governance framework and a 30/60/90-day roadmap. Ours is £12,000, net of VAT, over two weeks.
What does AI consulting cost for a small or mid-sized company?
A 50–200 person company should expect £3,500–£15,000 to get a credible audit and plan, and £15,000–£50,000 for a quarter that includes training and measured adoption. Six-figure proposals at this size deserve scepticism.
Are London AI consultant rates higher than the rest of the UK?
Modestly, and mostly at the top tier where London-based strategy houses price nationally anyway. Remote delivery has largely flattened the gap for advisory and training work.
Can I negotiate AI consulting fees?
Scope is more negotiable than rate. Cutting a business unit or phasing the programme moves the price honestly; discounting a day rate usually just moves seniority out of your team.
