The challenge
Why UK companies struggle with prompt engineering.
Every company integrating LLMs has the same problem: prompts that work in a demo break in production. Output quality varies wildly across edge cases. Hallucinations appear when inputs deviate from the examples you tested with. Your engineers wrote the initial prompts in an afternoon, but nobody owns ongoing optimisation. Hiring a dedicated prompt engineer in London costs £50,000–£70,000 — and the discipline is so new that most candidates have three months of experience and a portfolio of ChatGPT screenshots.
