How long is a piece of string? A rough guide is a simple proof of concept may cost between £0 and £5,000 and typically takes 4–8 weeks, while a minimal viable product (MVP) usually ranges from £5,000 to £20,000 over 8–12 weeks. A full application can cost between £20,000 and £50,000 and take around 3–6 months to develop. More complicated applications often fall in the £50,000 to £100,000 range with timelines of 6–9 months, while complex business platforms can exceed £100,000 and take 9 months or more. Ultimately, the final cost depends on factors such as features, integrations, scalability, and ongoing support requirements.
