Who does the work
Person-days per role in each phase, low and high effort.
| Phase | Role | Days (low to high) |
|---|---|---|
| Process mapping | Business analyst | 6 to 12 days |
| Build | AI engineer | 15 to 30 days |

| Test and rollout | Project manager | 3 to 6 days |
How the cost adds up
| Role | Low (days × 25th percentile) | Typical (days × median) | High (days × 90th percentile) |
|---|---|---|---|
| Business analyst | 6 × £425 = £2,550 | 9 × £500 = £4,500 | 12 × £662 = £7,944 |
| AI engineer | 15 × £488 = £7,320 | 22.5 × £589 = £13,253 | 30 × £863 = £25,890 |
| Generative AI (LLM) engineer | 3 × £417 = £1,251 | 6 × £543 = £3,258 | 9 × £825 = £7,425 |
| Test engineer | 3 × £350 = £1,050 | 4.5 × £438 = £1,971 | 6 × £588 = £3,528 |
| Project manager | 3 × £451 = £1,353 | 4.5 × £540 = £2,430 | 6 × £714 = £4,284 |
| Total, rounded | £14,000 | £25,000 | £49,000 |
How these estimates are worked out
Effort: for each phase we estimate how many days each role works, as a low and a high case. These are our estimates for a typical project of this kind, not measured data.
Rates: each role's daily rate comes from UK contract job adverts over the last six months, as published by IT Jobs Watch. These are freelance contractor rates as advertised, not what was paid, and not what a consultancy or agency charges.
Low end: the low-effort days at each role's 25th-percentile rate. We use the 25th percentile, not the 10th, because the lowest effort at the cheapest rates gives a floor few buyers would ever meet.
Typical: the mid-point between low and high effort, at each role's median rate.
High end: the high-effort days at each role's 90th-percentile rate.
Totals are rounded to the nearest £500 below £10,000 and the nearest £1,000 above, and exclude VAT. Phases run one after another.
Not included:
- Software licences, model and hosting fees
- Travel and expenses
- Your own staff's time
- A consultancy's or agency's margin, overheads and risk
Real prices vary with the supplier, the state of your data and systems, how much of the work your own team does, where the work happens and how much risk the supplier carries. Consultancies and agencies usually charge more than these contractor rates, and a fixed price usually costs more than time and materials because the supplier takes the risk.
