AI audit pricing in the UK is genuinely confusing: the same phrase covers a free five-minute quiz and a four-week £6,000 engagement. Here are the real numbers as of mid-2026, from published prices across the market.

The price bands

Free (£0). Web quizzes and short discovery calls. Some are honest lead magnets that give you a useful summary — including ours, a ten-minute AI voice audit with a written report. Others are thin questionnaires that funnel straight to a pitch. The test: do you keep something useful if you never speak to them again?

Fixed-fee light audits (£300–£1,000). A structured interview, workflow review, and a short recommendations report — typically 5–7 specific suggestions. Providers in this band publish prices around £499–£999. Good value when you want an independent second opinion in writing.

Structured engagements (£1,500–£6,000+). Two-to-four-week assessments with workflow mapping, data infrastructure review, ROI projections, and a prioritised roadmap. Pricing scales with headcount — roughly £1,500 for a five-person business to £6,000+ for thirty staff. Worth it when you're planning real investment and need the business case.

Enterprise data readiness (£5,000+). A different product: assessing whether your data foundations can support AI at all. Ours is from £5,000 +VAT, and it exists because 88% of AI projects stall on data, not technology.

What drives the price

Time with senior people, mostly. An audit's value is judgment — someone who has seen enough businesses to know which of your fifteen possible AI projects are the two worth doing, and which will quietly eat a year. Automated scoring is cheap because it doesn't contain judgment.

How to choose

If you're curious but uncommitted: start free, but pick one that produces a written output. Ten minutes of your time should still earn you a document.
If you're comparing quotes for a specific automation: a £500-ish fixed-fee audit gives you an independent written opinion to negotiate with.
If you're budgeting real money: pay for the structured engagement — the roadmap pays for itself in avoided false starts.

Our own free audit is the first kind, deliberately: ten minutes with Alice, a written summary of where AI genuinely helps your business — and where it doesn't — no obligation, and every follow-on price published on the packages page.
