What is Proof of Concept? — UK Software Development Guide
Direct Answer
A Proof of Concept (PoC) is a demonstration that a specific technical approach is feasible — proving that a concept can work before committing to a full implementation. A PoC is typically internal, not production-quality, and focuses on answering a single technical question. It is distinct from a Prototype (which demonstrates UI/UX) and an MVP (which is production-quality software for real users).
POC in the UK
PoC development is common in UK enterprise and deep tech contexts: pharmaceutical companies commission PoCs for AI diagnostics before regulatory pathway; FinTechs run technical PoCs for novel Open Banking or DLT approaches before FCA Sandbox application; GovTech teams commission PoCs before G-Cloud procurement. R&D Tax Credits may apply to PoC work where genuine technological uncertainty is being tested — the PoC phase is often the most straightforwardly qualifying R&D activity. ClickMasters delivers PoCs for £8,000–£25,000 depending on complexity.
